Introduction: Fifty percent of pregnant females experience pain with 20% reporting long-term pain post-partum. Pregnant females undergo changes in foot anthropometry, lower extremity alignment, and joint laxity. It is unknown if asymmetric alterations may be related to development of pain. The purpose of this study was twofold: 1) to compare asymmetric alignment in pregnant females with and without pain during pregnancy and in nulliparous controls and 2) to assess the relationship between asymmetric alignment and pain severity in all participants. Methods: Ten pregnant females in their third trimester and nine nulliparous controls participated. Bilateral asymmetry of foot length, width, arch index, arch height index, arch rigidity index, arch drop, rearfoot angle, and pelvic obliquity were determined. Joint laxity and musculoskeletal pain were also assessed. ANOVAs were utilized to compare asymmetries between pregnant females reporting pain (n = 5), those not reporting pain (n = 5), and controls. Spearman's Rho correlations were used to relate asymmetry to pain magnitude (α = 0.05). Results: No statistical differences (p>0.05) were found between pregnant females with or without pain and controls for any of the metrics. Negative correlations were found between arch index asymmetry and low back pain (p = 0.005), foot length asymmetry and lower leg pain (p = 0.008), and pelvic obliquity and lower leg pain (p = 0.020). Positive correlations were found between foot width asymmetry and knee pain (p = 0.028), as well as arch drop asymmetry and upper leg (p = 0.024), knee (p = 0.005), and lower leg pain (p = 0.019). Conclusions: This study was successful in identifying potential targets for prevention and treatment of pain in pregnancy. Furthermore, because pain during pregnancy may be predictive of pain post-partum, it is important to conduct future research to determine both if interventions such as footwear or exercise can prevent or treat these asymmetries and prevent post-partum pain.

This was a single-centre retrospective study. Minimally invasive techniques for transforaminal lumbar interbody fusion (MIS-TLIF), oblique lumbar interbody fusion (OLIF), and percutaneous endoscopic transforaminal lumbar interbody fusion (Endo-TLIF) have been extensively used for lumbar degenerative diseases. The present study analyses the short-term and mid-term clinical effects of the above three minimally invasive techniques on L4/L5 degenerative spondylolisthesis. In this retrospective study, 98 patients with L4/L5 degenerative spondylolisthesis received MIS-TLIF, 107 received OLIF, and 114 received Endo-TLIF. All patients were followed up for at least one year. We compared patient data, including age, sex, body mass index (BMI), Oswestry disability index (ODI), visual analogue scale of low back pain (VAS-B), visual analogue scale of leg pain (VAS-L), surgical time, blood loss, drainage volume, hospital stay, complications, and neurological status. Moreover, we performed imaging evaluations, including lumbar lordosis angle (LLA), disc height (DH) and intervertebral fusion status. No significant differences were noted in age, sex, BMI, preoperative ODI, preoperative VAS-B, preoperative VAS-L, preoperative LLA, or preoperative DH. Patients who underwent OLIF had significantly decreased blood loss, a lower drainage volume, and a shorter hospital stay than those who underwent MIS-TLIF or Endo-TLIF (P < 0.05). The VAS-B in the OLIF group significantly decreased compared with in the MIS-TLIF and Endo-TLIF groups at 6 and 12 months postoperatively (P < 0.05). The VAS-L in the Endo-TLIF group significantly decreased compared with that in the MIS-TLIF and OLIF groups at 6 months postoperatively (P < 0.05). The ODI in the OLIF group was significantly better than that in the MIS-TLIF and Endo-TLIF groups at 6 months postoperatively (P < 0.05). No statistically significant differences in the incidence of complications and healthcare cost were found among the three groups. Follow-up LLA and DH changes were significantly lower in the OLIF group than in the other groups (P < 0.05). The intervertebral fusion rate was significantly higher in the OLIF group than in the other groups at 6 and 12 months postoperatively (P < 0.05). In conclusion, while MIS-TLIF, OLIF, and Endo-TLIF techniques can effectively treat patients with L4/5 degenerative spondylolisthesis, OLIF has more benefits, including less operative blood loss, a shorter hospital stay, a smaller drainage volume, efficacy for back pain, effective maintenance of lumbar lordosis angle and disc height, and a higher fusion rate. OLIF should be the preferred surgical treatment for patients with L4/5 degenerative spondylolisthesis. [ABSTRACT FROM AUTHOR]

Introduction: Acute compartment syndrome of the thigh after total knee arthroplasty is a rarely described complication. After the assessment of the diagnosis, immediate surgical intervention is necessary to prevent further tissue damage. Since only a few cases have been described and because of the high complication rate, early detection is essential for ensuring patient outcomes. Case presentation: After total knee arthroplasty in a high-volume university hospital, a 57-year-old Caucasian female patient experienced strong, disproportional pain in the ventromedial thigh of the affected leg, which did not respond to an adequate adjustment in pain medication. Imaging revealed a distinct swelling of the vastus intermedius muscle. This resulted in acute compartment syndrome of the thigh, which was immediately surgically treated. Apart from receiving surgery distal from the affected compartment and continuous intake of acetylsalicylic acid, the patient had no risk factors for developing compartment syndrome. The patient's recovery was uneventful, with timely wound closure and discharge to outpatient care without significant functional limitations. Conclusion: Acute compartment syndrome of the thigh represents a rare, but severe complication that can occur after orthopedic surgery. In our case, no triggering factors for the development of acute compartment syndrome, such as the use of a tourniquet, were detected. Even in unusual locations, compartment syndrome should be considered as a differential diagnosis. With sufficient evidence, immediate fasciotomy should be indicated. [ABSTRACT FROM AUTHOR]

Background: Percutaneous transforaminal endoscopic decompression (PTED) is an ideal minimally invasive decompression technique for the treatment of lumbar spinal stenosis (LSS) with degenerative lumbar spondylolisthesis (DLS). The posterosuperior region underneath the slipping vertebral body (PRSVB) formed by DLS is an important factor exacerbating LSS in patients. Therefore, the necessity of removing the PRSVB during ventral decompression remains to be discussed. This study aimed to describe the procedure of PTED combined with the removal of the PRSVB and to evaluate the clinical outcomes. Methods: LSS with DLS was diagnosed in 44 consecutive patients at our institution from January 2019 to July 2021, and they underwent PTED combined with the removal of the PRSVB. All patients were followed up for at least 12 months. The clinical outcomes were evaluated using the visual analog scale (VAS), Oswestry Disability Index (ODI), and modified MacNab criteria. Results: The mean age of the patients was 69.5 ± 7.1 years. The mean preoperative ODI score, VAS score of the low back, and VAS score of the leg were 68.3 ± 10.8, 5.8 ± 1.0, and 7.7 ± 1.1, respectively, which improved to 18.8 ± 5.0, 1.4 ± 0.8, and 1.6 ± 0.7, respectively, at 12 months postoperatively. The proportion of patients presenting "good" and "excellent" ratings according to the modified MacNab criteria was 93.2%. The percent slippage in spondylolisthesis preoperatively (16.0% ± 3.3%) and at the end of follow-up (15.8% ± 3.3%) did not differ significantly (p>0.05). One patient had a dural tear, and one patient had postoperative dysesthesia. Conclusions: Increasing the removal of PRSVB during the PTED process may be a beneficial surgical procedure for alleviating clinical symptoms in patients with LSS and DLS. However, long-term follow-up is needed to study clinical effects. [ABSTRACT FROM AUTHOR]

Background: No other systematic review examined the measurement properties of the TUG in LSS. The present systematic review and meta-analysis aimed to investigate the measurement properties of the Timed Up and Go (TUG) in patients with Lumbar Spine Surgery (LSS). A literature search yielded 906 studies [PubMed:71, Web of Science (WoS):80, Scopus:214, ScienceDirect:471 and Cochrane Library:70]. Included 10 studies were assessed for risk of bias and quality using the "four-point COSMIN tool" and "COSMIN quality criteria tool". Criterion validity and responsiveness results were pooled with "correlation coefficient" and "Hedges' g" based effect size, respectively. Results: The correlation coefficient pooling between TUG and VAS back and leg pain was 0.26 (moderate) (95% CI 0.19–0.34) and 0.28 (moderate) (95% CI 0.20–0.36). The pooled coefficient of TUG with ODI and RMDI was 0.33 (moderate) (95% CI 0.27–0.39) and 0.33 (moderate) (95% CI 0.24–0.42), respectively. Besides, TUG has correlated with the quality-of-life PROMs with a coefficient of − 0.22 to − 0.26 (moderate) (EQ5D Index 95% CI − 0.35 to − 0.16), (SF12-PCS 95% CI − 0.33 to − 0.15) and (SF12-MCS 95% CI − 0.32 to − 0.13). The pooled coefficient of TUG with COMI, ZCQ-PF and ZCQ-SS was 0.46 (moderate) (95% CI 0.30–0.59), 0.43 (moderate) (95% CI 0.26–0.56), and 0.38 (moderate) (95% CI 0.21–0.52), respectively. TUG's 3-day and 6-week responsiveness results were 0.14 (low) (95% CI − 0.02 to 0.29) and 0.74 (moderate to strong) (95% CI 0.60–0.89), respectively. TUG was responsive at the mid-term (6 weeks) follow-up. Conclusion: In clinical practice, the TUG can be used as a reliable, valid and responsive tool to assess LSS patients' general status, especially in mid-term. [ABSTRACT FROM AUTHOR]

(1) Objectives: The objective of this study was to quantify the exact clinical-radiological efficacy and safety of the extreme lateral interbody fusion (XLIF) technique in spinal surgery; (2) Methods: A meta-analysis was performed using PubMed, Embase, Scopus, and Cochrane Collaboration Library. Studies focusing on patients surgically treated with XLIF were included. The outcomes were as follows: visual analog scale (VAS) and Oswestry disability index (ODI), radiological outcomes, and adverse events. Cohort studies and case series were also included. Clinical outcomes were assessed at 12 months of age. Data were combined using Review Manager 5.4 and WebPlotDigitizer 13.1.4; (3) Results: Nineteen studies with a pool of 1409 patients were included in this meta-analysis. Leg pain VAS and back pain VAS significantly improved at 12 months (SMD 2.75, 95% CI 0.59–4.90; SMD 4.54, 95% CI 1.39–7.69). ODI showed significant improvement (MD 32.51, 95% CI 24.01–41.00) at 12 months. Disc height increased significantly (SMD −2.73, 95% CI −3.58 to −1.88). Lumbar lordosis and segmental lordosis were significantly corrected postoperatively (MD −2.44, 95% CI −3.45 to −1.43; MD −2.55, 95% CI −3.61 to −1.48). The fusion rates at 12 months ranged from 85.0% to 93.3%. The most frequent complications were transient neurological conditions (2.2%), hardware failure (1.9%), and transient pain (1.8%). The most frequent serious complications were nerve root injury (1.0%), gastrointestinal impairment (0.7%), and vertebral fractures (0.6%); (4) Conclusions: This is the first meta-analysis of the specific use of XLIF in spinal surgery. This study demonstrates that the XLIF technique in spine surgery is associated with good clinical and radiological results and a low complication rate. [ABSTRACT FROM AUTHOR]

Background: Considering the epidemiology of single-level lumbar disc herniations (LDH) in the young and active patients, the impact on working capacity is highly relevant. The timing of return-to-work after lumbar surgery through various modalities differs greatly. This may be partly due diverse disparate surgical approaches along with differences in patient and surgeon. The purpose of this paper is to provide evidence for a return-to-work policy after endoscopic sequestrectomy and discuss possible clues to a faster recovery of patients that did not receive a sick-leave report via a case series. Case presentation: The sample comprises fourteen cases of single-level LDH that underwent endoscopic interlaminar sequestrectomy and did not receive a sick-leave report and were advised to return-to-work whenever they felt fit so. Time until return-to-work, pre- and post-operative leg VAS pain scores and amount of analgesic used post-operatively were retrospectively analyzed. Fourteen patients were operated on using the same technique and on average returned to work after 6.6 ± 1.8 days, used 3.7 ± 2.5 analgesic tablets before returning to work and had a postoperative leg VAS pain score of 1.4 ± 1.2. No patient requested a sick-leave report during the follow-up period of 1 month. Conclusions: The patients in this case series had a remarkably short period of sick-leave and a low number of analgesic usage. These findings may be due to selection of patients who were operated on specifically for leg pain with the absence of lower back pain suggesting integrity of annulus fibrosus. We can postulate that intraoperative preservation of lamina, facet joint and annulus fibrosus along with reassurance of the surgeon suggesting to return-to-work whenever fell fit so were the key factors in the swifter recovery of the patients.

Background: Many patients with transverse myelitis suffer from sensory loss below the spinal level of the lesion. This is commonly associated with chronic neuropathic pain. However, the presence of somatic pain below a complete thoracic sensory level after transverse myelitis is exceptionally rare, and it is unclear if surgical decompression is an effective form of treatment for these patients. Case presentation: In this report, we describe a 22-year-old Caucasian female who suffered from chronic lumbar back pain despite a complete thoracic sensory level secondary to prior transverse myelitis. Imaging demonstrated multilevel central stenosis below the sensory level, and her pain improved after surgical decompression. To our knowledge, this is the first reported case of symptomatic lumbar stenosis below a sensory level after transverse myelitis successfully treated with surgical decompression. Conclusion: This is the first reported case of a patient with symptomatic lumbar stenosis after transverse myelitis whose lower back pain and quality of life improved following surgical decompression and fusion. This case provides evidence that typical lumbago is possible in patients with sensory loss from transverse myelitis, and standard lumbar decompression may provide benefit for these patients.

Background: Both instrumented and stand-alone lateral lumbar interbody fusion (LLIF) have been widely used to treat lumbar degenerative disease. However, it remains controversial as whether posterior internal fixation is required when LLIF is performed. This meta-analysis aims to compare the radiographic and clinical results between instrumented and stand-alone LLIF. Methods: PubMed, EMBASE and Cochrane Collaboration Library up to March 2023 were searched for studies that compared instrumented and stand-alone LLIF in the treatment of lumbar degenerative disease. The following outcomes were extracted for comparison: interbody fusion rate, cage subsidence rate, reoperation rate, restoration of disc height, segmental lordosis, lumbar lordosis, visual analog scale (VAS) scores of low-back and leg pain and Oswestry Disability Index (ODI) scores. Results: 13 studies involving 1063 patients were included. The pooled results showed that instrumented LLIF had higher fusion rate (OR 2.09; 95% CI 1.16–3.75; P = 0.01), lower cage subsidence (OR 0.50; 95% CI 0.37–0.68; P < 0.001) and reoperation rate (OR 0.28; 95% CI 0.10–0.79; P = 0.02), and more restoration of disc height (MD 0.85; 95% CI 0.18–1.53; P = 0.01) than stand-alone LLIF. The ODI and VAS scores were similar between instrumented and stand-alone LLIF at the last follow-up. Conclusions: Based on this meta-analysis, instrumented LLIF is associated with higher rate of fusion, lower rate of cage subsidence and reoperation, and more restoration of disc height than stand-alone LLIF. For patients with high risk factors of cage subsidence, instrumented LLIF should be applied to reduce postoperative complications. [ABSTRACT FROM AUTHOR]

Some patients with lumbar spine stenosis (LSS) have severe low back pain (LBP) with only mild leg symptoms. The effects of decompression surgery for such patients remain unknown. Of 818 patients with LSS who underwent surgical treatment in our institution from 2011 to 2019, eight patients had a numeric rating scale (NRS) score of ≥7 for LBP and 3≤ for leg pain. The patients' age, sex, clinical characteristics, preoperative leg symptoms, and level of LSS were investigated. The detailed characteristics of LBP, such as the disease duration, location of LBP, and exacerbating factors, were obtained from each patient. The NRS and Japanese Orthopaedic Association (JOA) scores for LBP were evaluated on admission, at 1 and 3 months postoperatively, and at the final follow-up (>1 year postoperatively). All patients were male with a mean age of 71.5 years (range, 57–82 years). LBP was exacerbated during walking in six patients and during an extension posture in three patients. The median duration of LBP was 2.9 years (range, 0.3–7 years). The stenosis was located at L2/3 in three patients, L3/4 in five patients, and L4/5 in seven patients. The stenosis involved one level in three patients and more than two levels in five patients. Other pathologies, such as sacroiliac joint lesions, facet pain, superior/middle cluneal nerve pain, and discogenic pain, were excluded by diagnostic anesthetic block and detailed physical examination. All patients underwent posterior decompression surgery without fusion. In all eight patients, the NRS score for LBP significantly improved from 7.6 (range, 7–10) to 1.7 (range, 0–3) and the JOA score improved from 13.1 (range, 4–19) to 21.8 (range, 18–27). A low proportion of patients showed walking-evoked severe LBP with mild leg symptoms due to lumbar spine stenosis. The patients' pain was improved by decompression surgery with satisfactory results.

Study Design: A retrospective cohort study. Purpose: To analyze the association between preoperative adjacent facet joint osteoarthritis (FJOA) and outcomes of lumbar interbody fusion (LIF). Overview of Literature: Whether preoperative adjacent FJOA is associated with the incidence of radiological adjacent segment degeneration (RASD) and low back pain (LBP) relief after lumbar fusion remains unknown. Methods: The study included patients who underwent LIF. The demographic characteristics and radiographic and surgical data were collected and evaluated. The included patients were divided into control group and FJOA group based on the preoperative adjacent facet joint Pathria grade. Preoperative and last follow-up LBP Visual Analog Scale (VAS) score, leg pain (LP) VAS, Oswestry Disability Index (ODI) and RASD were evaluated and compared. The improvement rates in VAS and ODI were calculated and compared between the two groups. Logistic regression was used to analyze the risk factors of LBP relief and incidence of RASD. Results: In total, 197 patients (control group, 86; FJOA group, 111) were included, and the median follow-up was 46 months. The VAS and ODI in both groups significantly improved after surgery. At the last follow-up, the FJOA group had higher VAS and lower VAS improvement rates of LBP than the control group (p <0.05). However, no significant difference in the LP VAS and ODI was found between the two groups. The incidence of RASD in the FJOA group was significantly higher than that in the control group (48.6% vs. 30.2%, p =0.034). Multivariate logistic regression analysis showed that preoperative adjacent FJOA was significantly associated with LBP relief (odds ratio [OR], 0.691; 95% confidence interval [CI], 0.498-0.958) and the postoperative incidence of RASD (OR, 1.406; 95% CI, 1.020-1.939). Conclusions: The preoperative FJOA in the adjacent segments was significantly associated with LBP following LIF. Patients with preoperative FJOA were more likely to have RASD following lumbar fusion surgery. [ABSTRACT FROM AUTHOR]

Chronic recurrent multifocal osteomyelitis (CRMO) is an autoinflammatory bone disease predominantly affecting the metaphyses of long bones and is usually seen in children. Although CRMO is generally a pediatric disease, it may also occur in adults. This may result in a delay in the diagnosis of adult-onset CRMO. This report presents an adult-onset female patient who presented with left leg pain followed by swelling in the right knee. The patient was initially started on colchicine treatment, but, due to unresponsiveness in the follow-up the patient, the treatment was switched to a combination of methotrexate and prednisolone. A satisfactory clinical recovery was achieved with these drugs. CRMO could be considered in the differential diagnosis of patients presenting with bone pain and joint complaints. Considering that the disease progresses with clinical flare-ups and remission periods, it should be kept in mind that patients should be followed closely and treatment can be changed.

Objectives: Transcranial direct current stimulation (tDCS) is a promising non-invasive brain stimulation technique for treating chronic pain, yet its effectiveness in chronic lower extremity pain due to lumbar spinal stenosis (LSS) has not been studied. This research aimed to investigate the impact of tDCS on pain, walking capacity, functional status, and quality of life in LSS patients. Patients and methods: In this prospective, randomized, double-blind, sham-controlled study, 32 LSS patients received either real or sham tDCS over the motor cortex contralateral to the patient's painful lower extremity for 10 consecutive weekdays (10 sessions). Evaluations were conducted at baseline, post-session, and 1–3 months later. The pain was evaluated by Visual Analog Scale (VAS), walking duration and distance by Treadmill Walking Test, functional status by Modified Oswestry Disability Questionnaire (MODQ) and quality of life by Short Form-36 (SF-36). Results: In-group comparisons, active tDCS showed sustained analgesic effects for 3-month post-treatment, distinct from sham. After the final session, active group exhibited significantly better asymptomatic walking distance and duration. Active stimulation led to notably lower MOLBDQ scores after 1 month. Significant improvements in SF-36 subscales were seen after 3 months, especially in pain, physical functioning, and general health. Positive tDCS effects on pain, claudication, and some quality of life aspects were evident at 3 months, while functional status improvements were mainly limited to 1 month. Conclusion: tDCS shows potential as a safe, non-invasive technique for alleviating chronic LSS-related pain, enhancing mobility, functionality, and quality of life.

Calcineurin inhibitor pain syndrome (CIPS) is a rare complication of graft-vs-host disease prophylaxis following allogeneic hematopoietic cell transplant (alloHCT). CIPS presents as severe bilateral lower extremity pain, and the incidence, risk factors, and management of CIPS are poorly characterized. This is a single center retrospective study of patients who received tacrolimus (TAC) following alloHCT to describe the characteristics and management of CIPS and compare to a cohort who did not develop CIPS. Fifteen of 585 alloHCT patients (2.6%) developed CIPS at a median of 5 days following TAC initiation and a median level of 10.5 ng/mL. Severe bilateral foot, ankle, or leg pain were the primary symptoms. Patients with CIPS were younger and more frequently received myeloablative conditioning and total body irradiation compared to patients without CIPS. Analgesic regimens included dihydropyridine calcium channel blockers, gabapentinoids, topical diclofenac, and opioids. Clinicians should be aware of this uncommon but severe adverse effect.

Purpose: Prospective comparison of the efficacy and safety of transforaminal endoscopic lumbar discectomy (TELD) with a 45° puncture angle versus traditional Thomas Hoogland endoscopy spine systems (THESYS) for the surgical treatment of L5/S1 lumbar disc herniation (LDH). Methods: Consecutive patients with L5/S1 LDH who underwent TELD were randomized (1:1) assigned to the 45° TELD group and the THESYS group. Clinical outcomes were assessed at pre-operation, 1-day and 3/6-months post-operation till final follow-up. Surgical-related parameters, visual analogue scale (VAS) score, oswestry disability index (ODI), and modified MacNab criteria, and surgical complications were recorded and analysed. Results: All patients were followed up for at least 24 months. Compared to the THESYS group, the 45° TELD group had a shorter operative time (P < 0.001) and intraoperative radiation time (P < 0.001) and a smaller VAS score for back pain (P < 0.001) and leg pain intraoperatively (P < 0.001). The VAS and ODI in the 45° TELD group were significantly better than those in the THESYS group within 3 months postoperatively. However, from 3 months on, both groups showed comparable VAS and ODI. There was no significant difference between the two groups of modified MacNab criteria. There were two cases of residual disc and two cases of recurrence that required reoperation in the THESYS group. Conclusion: For L5/S1 LDH, the 45° TELD technique was superior to traditional THESYS in terms of surgery-related parameters and faster improvement of VAS and ODI, with a lower complication rate.

Purpose: To investigate the clinical results and radiological parameters changes after unilateral-approach endoscopic lumbar interbody fusion (Endo-LIF) for lumbar spondylolisthesis with bilateral symptoms. Methods: 43 single-level lumbar spondylolisthesis patients with bilateral lower limb symptoms were included from June 2020 to May 2022. All patients underwent unilateral-approach Endo-LIF and postoperative computed tomography. Radiological parameters including disk height (DH), degree of upper vertebral slip (DUVS), and foramen intervertebral parameters including bilateral foraminal height (FH), contralateral foraminal areas (FA) were evaluated. The clinical outcomes including low back pain and bilateral leg pain were evaluated using Visual Analog Scale (VAS) and the Oswestry Disability Index (ODI) before and after surgery. Results: All cases were successfully completed surgery and followed for average 15.16 ± 5.2 months. DH (44% ± 11%) and DUVS were significantly improvement postoperatively compared with preoperatively (p < 0.05). Statistically significant increases in bilateral FH (25% ± 11% on the surgical side, 17% ± 8% on the contralateral side) and contralateral FA (26% ± 6%) were observed (p < 0.05). The VAS and the ODI scores were significantly decreased in comparison with the preoperative scores (p < 0.05). Conclusion: Unilateral-approach with contralateral indirect decompression in Endo-LIF can acquire satisfactory clinical outcomes. Therefore, unilateral-approach Endo-LIF may be a promising option for lumbar spondylolisthesis with bilateral symptoms. [ABSTRACT FROM AUTHOR]

Little information is available about the minimal clinically important differences (MCIDs) for objective physical measurements in people with lumbar spinal stenosis (LSS). To use disorder-specific anchor and, multiple anchor-, and distribution-based approaches to determine the MCIDs for walking capacity and physical activity in patients with LSS receiving nonsurgical treatment. Secondary analysis of a randomized controlled trial. Sixty-nine patients with neurogenic claudication caused by LSS receiving outpatient physical therapy. Zurich claudication questionnaire (ZCQ), self-paced walking test (SPWT), and number of daily steps measured by pedometry. All patients completed the ZCQ, SPWT, and pedometry at the baseline and after 6 weeks. For the anchor-based approach, ZCQ symptom severity, physical function, and satisfaction subscales were used as the external anchors. Using the receiver-operating characteristic (ROC) curve, the MCIDs were determined based on the optimal cutoff points for changes in the SPWT or daily steps. For the distribution-based approach, the MCIDs were estimated from the standard deviations (SDs) of the baseline scores of the SPWT and daily steps. In the anchor-based approach, only the ZCQ satisfaction subscale for the SPWT (0.73), and ZCQ symptom severity subscale for daily steps (0.71) exceeded the area under the ROC curve value of 0.7, which is considered acceptable. When using these subscales as anchors, the ROC curves and optimal cutoff points indicated MCIDs of 151 m for the SPWT and 1,149 steps for daily steps. The distribution-based approach estimated the MCIDs as 280 m for the SPWT and 1,274 steps for daily steps, and had a moderate effect size (0.5 SD). The anchor-based approach had limited external responsiveness when the ZCQ was used as the anchor. However, this information may be helpful for interpreting walking capacity and physical activity in patients with LSS receiving nonsurgical treatment and for estimating power and sample size when planning new trials.

Facet joint osteoarthritis (FJOA) is associated with lumbar disc degeneration and has a significant role in the development of lumbar spinal stenosis (LSS). The relationship between various radiographic parameters and the grade of FJOA is not well understood. To explore radiographical parameters associated with FJOA in LSS without lumbar dynamic instability. Retrospective study analysis. A total of 122 patients diagnosed with LSS who visited our hospital between January 2015 and July 2022. We evaluated radiographic parameters of patients at L4-5 including lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), grades of FJOA, facet joint orientation (FO), facet joint tropism (FT), intervertebral height index (IHI) and the relative cross-sectional area (RCSA) of paraspinal muscles. Patients diagnosed with LSS between January 2015 and July 2022 were enrolled. Demographic characteristics and radiographic parameters were collected. Spinopelvic parameters were measured through the preoperative lateral image of the whole spine, including LL, PI, pelvic tilt, and sacral slope. Lumbar computed tomography scan and magnetic resonance imaging were collected to measure the FO, FT, IHI, and the RCSA of paraspinal muscles respectively. Patients were divided into three groups according to the severity of FJOA graded by the Weishaupt classification: grade 0 and grade 1 were group A, grade 2 were group B, and grade 3 were group C. All variables were compared among the three groups, while the relationship between parameters and grades of FJOA were also analyzed. A total of 122 patients were included. PI was significantly greater in group C compared to group A (p = 0.025) and group B (p=0.022). FT was significantly greater in group C compared to group A (p<.001) and group B (p<.001). The RCSA of multifidus in group A were significantly greater than that in group B (p=0.02) and C (p=0.002). Additionally, FO in group C were significantly lower than group A (p<.001) and group B (p=0.028). The IHI in group C was significantly lower than group A (p=0.017). The correlation analysis indicated that grades of FJOA was positively related to Age, BMI (body mass index), PI, LL and FT, while negatively related to IHI, FO, RCSA of multifidus and RCSA of psoas major. Furthermore, the logistics regression showed that FT, PI, and IHI were important influence factors for FJOA. The current study confirmed that FT, PI and IHI were significantly associated with grades of FJOA at L4-5. Additionally, longitudinal studies are needed to understand the causal relationship between these parameters and FJOA. [ABSTRACT FROM AUTHOR]

Preoperatively, patients completed the ODI, as well as a modified ODI reflecting their expected improvement across the 10 ODI items. For example, item 1 in the ODI asks about Pain Intensity at the moment whereas the Expectations ODI asks "One year after surgery, I expect to have..." The difference between this modified ODI score and the baseline ODI score (Baseine ODI minus Expectations ODI) was defined as the Patient Expectation Score. Patients were stratified into tertiles based on their Expectations score into High (HE), Moderate (ME), and Low (LE) Expectations and compared. There were 30 patients in the HE, 35 in the ME, and 26 in the LE Group, with similar demographics and surgical parameters. Patients in the HE group had worse ODI scores preoperatively (54.96 vs 41.42, p<.001) and were expecting a greater improvement in ODI (43.8 vs 13.5, p<.001). There were fewer patients in the HE group (13, 43%) who reported that they were satisfied with the results compared to either the ME (20, 71%) or LE group (22, 85%, p=.041) despite having similar ODI scores and change in ODI scores 1 year postoperatively. An expectations tool, linked to a disease-specific measure may provide the clinician with a practical method of assessing a patient's expectation of results after treatment and aid in the shared decision-making during the preoperative surgical process.

Background: National survey data exploring the patient experience with lipedema are lacking. Methods: We conducted national surveys from 2016 to 2022 of women with lipedema as well as female controls. Surveys collected information on symptomatology, pain, and therapies. We performed logistic regression comparing symptoms among those with lipedema versus controls adjusting for age and BMI. Results: A total of 707 women with lipedema and 216 controls completed the surveys. Those with lipedema had a mean age of 48.6 years and mean BMI of 40.9 kg/m2. Lipedema symptom onset occurred frequently at puberty (48.0%) or pregnancy (41.2%). Compared to controls, women with lipedema were more likely to report leg swelling in heat (odds ratio [OR], 66.82; 95% CI, 33.04–135.12; p < 0.0001), easy bruising (OR, 26.23; 95% CI, 15.58–44.17; p < 0.0001), altered gait (OR, 15.54; 95% CI, 7.58–31.96; p < 0.0001), flu-like symptoms (OR, 12.99; 95% CI, 4.27–39.49; p < 0.0001), joint hypermobility (OR, 12.88; 95% CI, 6.68–24.81; p < 0.0001), cool skin (OR, 12.21; 95% CI, 5.20–28.69; p < 0.0001), varicose veins (OR, 11.29; 95% CI, 6.71–18.99; p < 0.0001), and fatigue (OR, 9.59; 95% CI, 6.10–15.09; p < 0.0001). Additionally, 70.3% had upper arm involvement, 21.2% reported foot swelling, and 16.6% reported foot pain. Most (52.2%) reported no symptom improvement with diet or exercise. Common therapies used included compression therapy (45.0%), gastric bypass (15.7%), and lower-extremity liposuction (14.0%). Conclusion: In a large, national, symptom survey, women with lipedema reported excess pain, swelling, and fat in the legs along with numerous symptoms beyond those classically described. Symptom responses to common therapies remain understudied. [ABSTRACT FROM AUTHOR]

Introduction: We developed a convolutional neural network (CNN) model to predict treatment outcomes of transforaminal epidural steroid injection (TFESI) for controlling cervical radicular pain due to cervical foraminal stenosis. Methods: We retrospectively recruited 293 patients with cervical TFESI due to cervical radicular pain caused by cervical foraminal stenosis. We obtained a single oblique cervical radiograph from each patient. We cut each oblique cervical radiograph image into a square shape, including the foramen that was targeted for TFESI, the intervertebral disc, the facet joint of the corresponding level with the targeted foramen, and the pedicles of the vertebral bodies just above and below the targeted foramen. Therefore, images including the targeted foramen and structures around the targeted foramen were used as input data. A favorable outcome was defined as a ≥ 50% reduction in the numeric rating scale (NRS) score at 2 months post TFESI compared to the pretreatment NRS score. A poor outcome was defined as a < 50% reduction in the NRS score at 2 months post TFESI vs. the pretreatment score. Results: The area under the curve of our developed model for predicting the treatment outcome of cervical TFESI in patients with cervical foraminal stenosis was 0.823. Conclusion: A CNN model trained using oblique cervical radiographs can be helpful in predicting treatment outcomes after cervical TFESI in patients with cervical foraminal stenosis. If the predictive accuracy is increased, we believe that the deep learning model using cervical radiographs as input data can be easily and widely used in clinics or hospitals.

Purpose: To report the development of a new sacroiliac joint (SIJ) arthrodesis system that can be used for isolated fusion of the SIJ and, unlike known implant systems, in combination with lumbar instrumentation or as an alternative to existing sacropelvic fixation (SPF) methods, and the patient-reported outcomes in two cases. Materials and Methods: After a comprehensive review of 207 pelvic computed tomography (CT) datasets, an implant body was designed. Its shape was modeled based on the SIJ recess. A screw anchored in the ilium secures the position of the implant and allows connection to lumbar instrumentation. Two patients with confirmed SIJ syndrome underwent surgery with the anatomically adapted implant. They were evaluated preoperatively, 6 months, and 12 months postoperatively. Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), Million Visual Analogue Scale (MVAS), Roland Morris Score (RMS), reduction of SIJ/leg pain, and work status were assessed. Bony fusion of the SIJ was evaluated by radiographs and CT 12 months after the procedure. Results: Analysis of pelvic CT data revealed a wedge-shaped implant body in four different sizes. In the two patients, VAS decreased from 88 to 33 points, ODI improved from 67 to 35%, MVAS decreased from 80 to 36%, and RMS decreased from 18 to 9 points 12 months after surgery. SIJ pain reduction was 80% and 90%, respectively. Follow-up CT and radiographs showed solid bony integration. Conclusion: The implant used takes into account the unique anatomy of the SIJ and also meets the requirements of a true arthrodesis. Initial results in two patients are promising. Biomechanical and clinical studies will have to show whether the considerable theoretical advantages of the new implant system over existing SIJ implants – in particular the possibility of connection to a lumbar stabilization system - and SPFs can be put into practice.

Exertional leg pain is a common problem in the athletic population, presenting with a constellation of similar symptoms. Delayed or incorrect diagnosis and treatment may result in significant morbidity and avoidable cessation of activity. Multiple causes such as chronic exertional compartment syndrome (CECS), medial tibial stress syndrome (MTSS), nerve or vascular entrapment syndromes may be responsible. A thorough history and focused clinical examination is mandated, and may yield clues as to the definitive diagnosis. Investigative adjuncts include imaging, compartment pressure measurement and electrodiagnostic studies. Whilst specific management depends on the underlying cause, the mainstay of initial management is activity modification, with surgery reserved for those who fail to respond to conservative measures.

Here we report the case of a 71-year-old woman who complained of lower back and left leg pain due to rod fracture following instrumented fusion using the lateral lumbar interbody fusion and multi-rod technique to treat adult spinal deformity. Radiographic images revealed bilateral rod fractures at L4-5 and pseudoarthrosis at L2-5; lower lumbar lordosis was minimal, but upper lumbar hyperlordosis was noted. The patient underwent revision surgery, which included posterior spinal instrument replacement, L3-4 and L4-5 lateral lumbar interbody fusion cage removal, and L4 vertebral body replacement via the anterior approach. This is a rare case of reoperation with the multi-rod technique. Revision surgery should be performed in consideration of the proportion of lumbar lordosis and anterior bony fusion as the posterior component is resected and bony fusion can only be achieved anteriorly.

Chronic exertional compartment syndrome (CECS) is a cause of exertional leg pain and has been reported in varying frequencies in males and females. Currently, it is unclear whether there are significant sex and gender differences in lower-limb CECS. Delineating sex and gender differences is vital in determining the causes of CECS and best treatments. This systematic review aimed to determine the sex/gender distribution of CECS and to assess for sex and gender differences in CECS diagnosis and outcomes. PubMed (Medline), Cochrane Library, and EMBASE databases were searched for studies that were published from January 2000-March 2022 and reported lower-limb CECS data in males and/or females. Data on CECS diagnosis (intracompartmental pressures) and outcomes (e.g. post-surgical return-to-sport, need for re-operation) with sex/gender breakdowns were extracted. The sex/gender distribution of CECS and prevalence of CECS by sex/gender were calculated. Forty-one studies were included in the systematic review; there were 27 retrospective reviews, 8 prospective studies, and 6 retrospective studies with prospective follow-ups. Thirty studies involved surgical populations. Sex/gender distribution of CECS was calculated using data from 24 studies; 51% were female. Prevalence of CECS was available in five studies and ranged widely for males (54%-73%) and females (43%-65%). Intracompartmental pressure data varied by sex/gender. Male athletes were more likely than female athletes to return to sport following surgery for CECS, but variations in all other post-surgical outcomes were observed between sexes and genders in the general population. Females represented 51% of the patients who were diagnosed with CECS among studies. Most CECS diagnosis and outcomes data varied by sex/gender, except for post-surgical outcomes data in athletes, which demonstrated that males had higher rates of return to sport than females. Future studies are needed to examine factors contributing to sex and gender differences in CECS diagnosis and outcomes. [ABSTRACT FROM AUTHOR]

Purpose: In this study, we evaluated the therapeutic outcomes of transforaminal epidural steroid injection (TFESI) in managing chronic radicular pain due to foraminal stenosis. Furthermore, we evaluated its effectiveness according to isthmic spondylolisthesis (IS) severity. Patients and Methods: We included 40 patients with radicular pain due to IS-derived foraminal stenosis in our study and treated them with TFESI. Two patients were lost during follow-up. Based on the lateral lumbar radiograph findings, we allocated the recruited patients with < 25% slippage by IS to Group 1 (n = 23) and those having 25– 50% slippage to Group 2 (n = 15). The degree of pain was measured using a numeric rating scale (NRS) at pre-treatment and 1 and 2 months after TFESI. Results: In 38 patients who completed the study, the NRS at pre-treatment was significantly reduced at the 1- and 2-month follow-ups. In the Group analysis, the NRS scores were significantly reduced after TFESI in both Groups 1 and 2, regardless of IS severity. However, the reduction in NRS scores 1 month after TFESI was significantly greater in Group 1 than in Group 2. Moreover, the rate of successful treatment outcomes was significantly higher (65.2%) in Group 1 than in Group 2 (26.7%). Conclusion: After TFESI, chronic radicular pain was significantly reduced regardless of IS severity, and its effect persisted for at least 2 months. However, its effect was superior when the vertebra slippage by IS was less than 25% compared to patients with 25%– 50%. [ABSTRACT FROM AUTHOR]

Introduction: Many clinical musculoskeletal pain conditions are characterized by chronic inflammation that sensitizes nociceptors. An unresolved issue is whether inflammation affects all nociceptors in a similar manner. Exercise-induced muscle damage (EIMD) has been proposed as a model for simulating clinical inflammatory pain in healthy samples. We sought to test the effect of EIMD on various painful stimuli (pressure and thermal), central pain processing (via the nociceptive flexion reflex) and endogenous pain modulation via conditioned pain modulation and exercise-induced hypoalgesia. Methods: Eighteen participants (9F, age: 24.6 ± 3.3) were recruited for repeated measures testing and each completed pain sensitivity testing prior to and 48 hours after an eccentric exercise protocol. The participants performed a minimum of 6 rounds of 10 eccentric knee extension exercises to induce muscle damage and localized inflammation in the right quadriceps. Force decrements, knee range-of-motion, and delayed onset muscle soreness (DOMS) were used to quantify EIMD. Results: There was a significant main effect of time for pressure pain (%diff; − 58.9 ± 23.1; p = 0.02, ηp2 = 0.28) but no significant main effect was observed for limb (%diff; − 15.5 ± 23.9; p = 0.53, ηp2 = 0.02). In contrast, there was a significant interaction between time and limb (p < 0.001, ηp2 = 0.47) whereby participants had lower pressure pain sensitivity in the right leg only after the damage protocol (%diff; − 105.9 ± 29.2; p = 0.002). Discussion: Individuals with chronic inflammatory pain usually have an increased sensitivity to pressure, thermal, and electrical stimuli, however, our sample, following muscle damage to induce acute inflammation only had sensitivity to mechanical pain. Exercise induced inflammation may reflect a peripheral sensitivity localized to the damaged muscle rather than a global sensitivity like those with chronic pain display. [ABSTRACT FROM AUTHOR]

Purpose: To investigate the clinical outcomes of percutaneous transforaminal endoscopic discectomy assisted with selective nerve root block for treating radicular pain with diagnostic uncertainty in the elderly. Methods: A total number of 36 elderly patients were included in the study. Clinical outcomes collected for analysis include operative time, hospital stay time, Visual Analog Scale, and Oswestry Disability Index before and after the surgery, the global outcome based on the Macnab outcome criteria. Results: Seventeen males and nineteen females with a mean age of 73.72 ± 7.15 were included in this study. Radicular pain was the main complaint of all the patients with the least symptom duration of two months. Radiological findings showed that 80.6% of the patients with multilevel disc herniation, 16.7% received lumbar fusion surgery before, and 8.3% with degenerative scoliosis. Besides, 69.4% of the patients have at least one comorbidity. 85.4% of the patients showed a positive response to selective nerve root block, and 91.6% of the patients reported a favorable outcome at the last follow-up. The mean value of pre-operative leg pain was 7.56 ± 0.74 and dramatically decreased after surgery (2.47 ± 0.81, P < 0.001). Besides, the mean value of Oswestry Disability Index decreased from 43.03 ± 4.43 to 5.92 ± 5.24 (P < 0.001) one year after the surgery. Conclusion: Multilevel degeneration of the lumbar spine is common in elderly patients. Identifying the responsible segment and decompressing the nerve root through minimally invasive surgery can provide a satisfactory clinical outcome for those with radicular pain as their primary complaint. And selective nerve root block is a reliable diagnostic tool for those with an ambiguous diagnosis. [ABSTRACT FROM AUTHOR]

Background: Lumbar disc herniation is one of the most common degenerative spine conditions. In our center, the standard surgical technique for treatment of lumbar disc herniation is open microdiscectomy. The full-endoscopic transforaminal discectomy is done for selective cases of lumbar disc herniation under local anesthesia, achieving good results. This study aims to compare the clinical outcomes, operative data, and complications of the treatment of lumbar disc herniation with "percutaneous full-endoscopic transforaminal discectomy" (TED) and the gold standard "open microdiscectomy" (MD). This was a randomized controlled trial that included 65 patients with lumbar disc herniation: 32 in the TED group and 33 in the MD group. Results: There was no statistically significant difference between the two groups with regard to the visual analogue scale (VAS) for leg pain, the VAS for back pain, or the Oswestry Low Back Pain Disability Questionnaire (ODI) score at the end of the 1-year follow-up. The operative time in minutes was statistically shorter in the TED group, with a mean value of 50.38 (± 11.65) and 61.09 (± 12.32) in the MD group. The blood loss was 77.33 CC (± 23.14) in the TED group and 170 CC (± 56.06) in the MD group. The mean duration of hospital stay in days was statistically shorter in the TED group. Exposure to radiation in minutes was higher in the TED group: 1.09 (± 0.33) and 0.18 (± 0.08) in the TED group and MD group, respectively. There was no statistically significant difference in the rate of complications. Conclusion: TED showed superiority over MD with regard to blood loss, operative time and shorter hospital stays, but with increased radiation exposure. There was no difference in clinical outcomes regarding VAS for leg and back pain and ODI score at 1 year follow-up with no significant difference in complications. [ABSTRACT FROM AUTHOR]

Purpose: To understand the current practice of radiation oncologists (ROs) and orthopedic surgeons (OSs) regarding spine metastasis. Methods: In 2022, an internet-based survey was conducted for ROs and OSs who treat spinal metastasis in Korea. Respondents were asked to choose the treatment option for two clinical scenarios. Scenario 1 involved a case displaying symptoms of leg weakness due to spinal cord compression and Scenario 2 involved a case with back pain due to pathologic compression fracture. The survey also included a question that required respondents to rank the importance of 11 clinical factors that affect treatment decisions. Results: Forty-nine ROs and 30 OSs responded to the survey. There were significant differences in treatment choices between two groups for both scenarios (P = 0.001). In Scenario 1, more OSs chose surgical resection than ROs (43.3% vs. 16.7%), while more ROs chose radiotherapy than OSs (83.3% vs. 53.3%). In Scenario 2, a similar proportion of OSs and ROs chose radiotherapy (OSs, 71.4% vs. ROs, 67.3%), while more OSs opted for prophylactic fixation after radiotherapy than ROs (95.0% vs. 42.4%). The top three factors influencing treatment decisions were general performance status, life expectancy, and spinal instability for both ROs and OSs. In both Scenarios 1 and 2, the treatment decisions of ROs changed significantly when clinical conditions related to these top three factors were altered. Conclusion: Although ROs and OSs share the same factors influencing treatment decisions for spinal metastases, notable differences exist in their actual [ABSTRACT FROM AUTHOR]

Background: Spinal manual therapy and corticosteroid nerve root injection are commonly used to treat patients with lumbar radiculopathy. The SALuBRITY trial—a two parallel group, double sham controlled, randomised clinical trial—is being developed to compare their effectiveness. By gathering patients' and clinicians' perspectives and involving them in discussions related to the trial research question and objectives, proposed trial recruitment processes, methods, and outcome measures, we aimed to improve the relevance and quality of the SALuBRITY trial. Methods: We involved patients with lived experience of lumbar radiculopathy (n = 5) and primary care clinicians (n = 4) with experience in the treatment of these patients. Involvement activities included an initial kick-off event to introduce the project, establishing a shared purpose statement, and empowering patient and clinician advisors for their involvement, followed by semi-structured group and individual interviews, and questionnaires to evaluate the experience throughout the project. Results: Both patient and clinician advisors endorsed the significance and relevance of the trial's objectives. Patients assessed the proposed trial methods as acceptable within the context of a trusting patient-clinician relationship. A trial recruitment and enrolment target time of up to five days was regarded as acceptable, although patients with chronic radiculopathy may need more time to consider their trial participation decision. All advisors reached consensus on the acceptability of a medication washout phase of 12- to 24-h before pain outcome measurement, with the inclusion of a rescue medication protocol. Both advisory groups preferred leg pain over back pain as the primary clinical outcome, with patient advisors advocating for personalized primary pain localization. Furthermore, patients requested expanding the pain, enjoyment, and general activity scale with peak pain intensity, rather than average pain alone. Patient and clinician advisors evaluated their engagement in clinical research as meaningful and impactful. Conclusion: Patient and public involvement resulted in important and relevant considerations for the SALuBRITY trial, spanning all research phases. These findings hold promise for enhancing the trial's quality and relevance and improving its translation into clinical practice. Plain English summary: In the SALuBRITY trial, we are comparing the effectiveness of two common treatments, spinal manual therapy and corticosteroid nerve root injection, for patients with lumbar radiculopathy, which is back pain that spreads into the leg because of an irritated nerve in the lower back. To ensure the trial's relevance and quality, we actively engaged both patients with lived experience of lumbar radiculopathy and primary care clinicians. Their valuable input supported the trial's objectives and found the proposed methods acceptable, especially in the context of a trusting patient-clinician relationship. Key consensus points included a reasonable recruitment and enrollment processing target time of up to five days, though chronic radiculopathy patients may need more time. A 12- to 24-h medication washout phase before pain assessment was endorsed, with emphasis on a rescue medication option. Leg pain was preferred over back pain as the primary outcome, and patients advocated for personalizing primary pain location. Our advisors evaluated their engagement in this patient and public involvement project as meaningful and impactful. Involving patients and clinicians in the SALuBRITY trial development process promises to enhance the trial's quality, relevance, and translation into clinical practice, ensuring it addresses the real needs and experiences of patients with lumbar radiculopathy.

Transforaminal lumbar interbody fusion (TLIF) is a universal surgical technique used to achieve lumbar fusion. Traditionally static cages have been used to restore the disc space after discectomy. However, newer technological advancements have brought up uniplanar expandable cages (UECs) and more recently bi-planar expandable cages (BECs), the latter with the hope of reducing the events of intra- or postoperative subsidence compared to UECs. However, since BECs are relatively new, there has been no comparison to UECs. In this PRISMA-compliant systematic review, we sought to identify all Medline and Embase reports that used UECs and/or BECs for TLIF or posterior lumbar interbody fusion. Primary outcomes included subsidence and fusion rates. Secondary outcomes included VAS back pain score, VAS leg pain score, ODI, and other complications. A meta-analysis of proportions was the main method used to evaluate the extracted data. Bias was assessed using the ROBINS-I tool. A total of 15 studies were pooled in the analysis, 3 of which described BECs. There were no studies directly comparing the UECs to BECs. A statistically significant difference in fusion rates was found between UECs and BECs (p = 0.04). Due to lack of direct comparative literature, definitive conclusions cannot be made about differences between UECs and BECs. The analysis showed a statistically higher fusion rate for BECs versus UECs, but this should be interpreted cautiously. No other statistically significant differences were found. As more direct comparative studies emerge, future meta-analyses may clarify potential differences between these cage types. [ABSTRACT FROM AUTHOR]

Background: Hip fractures are a major public health concern among middle-aged and older adults. It is important to understand the associated risk factors to inform health policies and develop better prevention strategies. Musculoskeletal pain is a possible implicating factor, being associated with physical inactivity and risk of falls. However, the association between musculoskeletal pain and hip fractures has not been clearly investigated. Methods: A nationally representative sample of the Chinese population was obtained from the China Health and Retirement Longitudinal Study (CHARLS). The study collected patient information on their demographic characteristics, socioeconomic status, other health-related behavior, and history of musculoskeletal pain and hip fractures. Univariate and multivariate analyses were conducted to investigate the factors influencing the risk of hip fracture, including factors related to the individual and to musculoskeletal pain. P for trend test was performed to assess the trend of each continuous variable. The robustness and bias were assessed using the bootstrap method. Restricted cubic spline regression was utilized to identify linear or non-linear relationships. Results: Among the 18,813 respondents, a total of 215 individuals reported that they have experienced a hip fracture. An increased risk of hip fracture was associated with the presence of waist pain and leg pain (P < 0.05), as well as with an increased number of musculoskeletal pain sites (P < 0.05). For individuals aged 65 and above, a significant association was found between age and the risk of hip fracture (P < 0.05). Furthermore, respondents with lower education level had a higher risk of hip fracture compared to those with higher education levels (P < 0.05). Conclusion: In the Chinese population, the risk of hip fracture was found to be associated with both the location and extent of musculoskeletal pain, as well as with other factors such as age and demographic characteristics. The findings of this study may be useful for informing policy development and treatment strategies, and provide evidence for comparison with data from other demographic populations.

Background: There are insufficient in-depth studies on whether percutaneous lumbar nucleoplasty (PLN) is effective and safe for the treatment of uncontained lumbar disc herniation (ULDH). This study aimed to investigate the clinical efficacy of PLN on radiating leg pain caused by ULDH. Methods: Patients who underwent PLN for ULDH and met the inclusion criteria between June 2018 and July 2022 were included. Clinical outcomes were evaluated using the numeric rating scale (NRS) for radiating pain preoperatively; at 1 day, 1 week, and 1 month postoperatively; and at the last follow-up. Patient satisfaction was assessed using MacNab criteria. Results: Forty-one patients were enrolled. The mean age was 50.2 years (range 24–73 years). The mean and standard deviation of the preoperative NRS in 39 patients with radiating pain was 9.0 ± 1.2. The NRS scores at 1 day, 1 week, and 1 month postoperatively and at the last follow-up were 4.6 ± 3.2, 3.6 ± 3.3, 2.9 ± 3.2, and 1.4 ± 2.0, respectively, showing significant improvement (all, p < 0.001). The number of patients (percentage) with excellent or good satisfaction according to the MacNab criteria was 29 (70.7%). Major complications were not observed. Three patients underwent additional surgery after PLN because of persistent radiating pain. Conclusions: PLN is a safe and feasible treatment option for ULDH. Treatment outcomes were favorable on average; however, the lack of consistency was a drawback. [ABSTRACT FROM AUTHOR]

Objective: To describe unilateral transforaminal lumbar interbody fusion (TLIF) via a modified hemilateral spinous process-splitting (MHSPS) approach and determine its effectiveness. Methods: Sixty-five consecutive patients with the lumbar degenerative disease who underwent MHSPS TLIF between August 2020 and July 2021 were retrospectively analyzed. Japanese Orthopedic Association (JOA) score and visual analog scale (VAS) scores for back and leg pain were evaluated before surgery and at the last follow-up. Postoperative paraspinal muscle atrophy was evaluated on axial T2-weighted magnetic resonance imaging. Results: Mean JOA score increased from 13.6 ± 3.21 before surgery to 24.72 ± 3.34 at last follow-up (p < 0.001). The mean recovery rate was 68.2% ± 5.68%. Clinical outcome was excellent in 22, good in 35, and fair in 8 patients. The VAS score for low back pain was significantly lower at the last follow-up than before surgery (1.18 ± 0.99 vs. 3.09 ± 1.35; p < 0.001). The VAS score for leg pain was also significantly lower at the last follow-up than before surgery (1.13 ± 0.91 vs. 6.61 ± 1.23; p < 0.001). The mean paraspinal muscle atrophy rate did not significantly differ between the symptomatic side (6% ± 3.8%) and asymptomatic side (4.8% ± 3.3%) at last follow -up (p = 0.071). Conclusion: MHSPS TLIF is an effective minimally invasive surgical treatment for selected types of degenerative lumbar disease. This technique can achieve effective spinal decompression and interbody fusion. Its advantages include direct and adequate visualization, vast surgical working space, short operation time, and minimal muscle injury. [ABSTRACT FROM AUTHOR]

Purpose: This retrospective cohort study aimed to evaluate the efficacy and safety of percutaneous endoscopic lumbar decompression (PELD) in elderly patients with lumbar spinal stenosis (LSS). Study Design: A matched retrospective study. Setting: The research was conducted in Beijing Chaoyang Hospital, Capital Medical University, China. Methods: This study included patients treated with PELD for LSS from September 2016 to September 2020. Patients with LSS aged ≥ 80 years were screened according to the inclusion and exclusion criteria as the study group, and then the same number of patients with LSS aged 50–80 years were matched according to gender, stenosis type, and surgical segment as the control group. Preoperative patient status was assessed using the Charlson comorbidity index (CCI) and the American Society of Anesthesiologists (ASA) physical status classification score. Clinical outcomes were assessed using the visual analog scale (VAS), Oswestry Disability Index (ODI) scores, modified Macnab criteria, radiological parameters and complication rates. Results: A total of 624 LSS patients met the screening criteria between September 2016 and September 2020, with 47 LSS patients ≥ 80 years old serving as the study group. Forty-seven LSS patients aged 50–80 years were matched to the study group according to gender, stenosis type, and stenosis segment. The CCI score (1.77 ± 1.67) and ASA classification (2.62 ± 0.74) of the study group were significantly higher than the CCI score (0.66 ± 0.96) and ASA classification (1.28 ± 0.54) of the control group, and the difference was statistically significant. Compared with preoperative data, postoperative ODI, leg pain VAS scores and back pain VAS scores were significantly improved in both groups (p < 0.05). However, no significant difference was found between two groups in preoperative and postoperative ODI, leg pain VAS scores and back pain VAS scores (p > 0.05). The operation time and postoperative hospital stay in control group were significantly lower than those in study (p < 0.05), but there was no significant difference in blood loss between the two groups (p > 0.05). Besides, overall radiological parameters were comparable in elder and younger patients (p > 0.05), and disc height (DH), lumbar lordosis and segmental lordosis decreased after two year follow-up in both groups (p < 0.05). In addition, complication rates were similar between the two groups (p > 0.05), and no serious complications and deaths were found. Limitations: Single-centre retrospective design, non-randomized sample, small sample size. Conclusion: Although elderly LSS patients (≥ 80 years old) are less fit and have more comorbidities, satisfactory outcomes can be achieved with PELD, comparable to those of LSS patients < 80 years old, and without increased complications.

Background: Exercise research targeting chronic kidney disease (CKD) has been conducted for more than 30years, and the benefits of exercise for CKD patients have been progressively demonstrated. This study analyzes citation classics on clinical intervention trials on exercise training and CKD to describe the research landscape and hotspots through bibliometric analysis. Methods: To identify clinical trials of exercise training interventions for CKD with more than 100 citations from the Web of Science Core Collection database. Extracted bibliometric information, participant information, and study characteristics of the included articles. The total citations, annual average citations, publication of year, author keywords, and study-related data were bibliometric analyzed and described using Excel 2019 and VOSviewer software. Results: A total of 30 citation classics were included, with a total citation frequency of 102 to 279 (mean±standard deviation: 148.4±49.4). The American Journal of Kidney Diseases (n=7) published the most (n=7) classic citations in the field of CKD exercise research, and the Journal of the American Society of Nephrology was the most cited. The hotspot of research around CKD and exercise training interventions focused on population (hemodialysis and end-stage renal disease), exercise type (resistance training, yoga, and leg-cycling), and outcomes (cardiovascular indices, physical performance, psychological status, kidney function, physical activity). Reported dropout rates ranged from 0.0% to 47.4%. Conclusion: A bibliometric analysis of citation classics on exercise training and CKD highlights the potential benefits of exercise as a non-pharmacological therapy for patients with CKD, as well as developments and hotspots in the field.

Background In this study, we evaluate the clinical efficacy and safety of full-endoscopic transforaminal lumbar interbody fusion (TLIF) for treatment of single-level lumbar degenerative spondylolisthesis. Methods Fifty-three patients were divided into two groups according to the surgical techniques: Full endoscopic (Endo)-TLIF (n = 25) and TLIF (n = 28). Clinical efficacy was evaluated pre- and postoperatively. The operation time, operative blood loss, postoperative amount of serum creatine phosphokinase (CPK), postoperative drainage volume, postoperative hospital stay time, total cost, and operative complications were also recorded. Results Compared with the TLIF group, the Endo-TLIF group had similar intraoperative blood loss, less postoperative increased CPK, less postoperative drainage volume, and shorter postoperative hospital stay, but longer operative time and higher total cost. The postoperative visual analog scale (VAS) scores of back and leg pain and Oswestry Disability Index (ODI) scores significantly improved compared with the preoperative scores in both two groups; more significant improvement of postoperative VAS scores of back pain and ODI scores were shown in the Endo-TLIF group at the 1-month follow-up (p < 0.05). No difference was found in the intervertebral fusion rate between the two groups. Conclusion The Endo-TLIF has similar clinical effect compared with the TLIF for the treatment of lumbar degenerative spondylolisthesis. It also has many surgical advantages such as less muscle trauma, less postoperative back pain, and fast functional recovery of the patient. However, steep learning curve, longer operative time, and higher total cost may be the disadvantages that limit this technique. Also, the Endo-TLIF treatment of patients with bilateral lateral recess stenosis is considered a relative contraindication. [ABSTRACT FROM AUTHOR]

Background The impact of minimally invasive decompression (MID) techniques on spinopelvic parameters and on the sagittal alignment remains a controversial topic. Here we studied the changes in clinical and radiologic parameters and their relationships in a series of lumbar spinal stenosis (LSS) submitted to MID with a minimum follow-up (FU) of 24 months. Methods We prospectively collected clinical and radiologic data of 20 consecutive patients who were evaluated preoperatively, at the 6-month FU, and at the 24-month FU. Visual analog scale (VAS) for back and leg pain, Oswestry disability index (ODI), neck disability index (NDI), sagittal vertical axis (SVA), C7 slope (C7S), lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT), and sacral slope (SS) were assessed for each patient. Moreover, the percentage variation of clinical and radiologic factors at the 24-month FU compared with the preoperative factors was calculated to perform correlation studies among these variables. Results We reported a significant improvement of all clinical parameters. A significant increase of LL and SS and a significant decrease of PT and SVA were observed. The preoperative values of ODI, LL, SS, PT, and SVA significantly affect the 24-month FU values, and the percentage improvement of SVA at the 24-month FU compared with the preoperative values was significantly related to the percentage improvement of LL. Conclusions MID is clinically effective in patients with LSS and improves the spinopelvic parameters and the global sagittal balance of the spine. The preoperative spinal alignment affects the spinal alignment at FU. The improvement of SVA was strictly related to the improvement of LL. [ABSTRACT FROM AUTHOR]

Symptomatic lumbar spinal stenosis (LSS) leads to functional impairment and pain. While radiologic characterization of the morphological stenosis grade can aid in the diagnosis, it may not always correlate with patient symptoms. Artificial intelligence (AI) may diagnose symptomatic LSS in patients solely based on self-reported history questionnaires. We evaluated multiple machine learning (ML) models to determine the likelihood of LSS using a self-reported questionnaire in patients experiencing low back pain and/or numbness in the legs. The questionnaire was built from peer-reviewed literature and a multidisciplinary panel of experts. Random forest, lasso logistic regression, support vector machine, gradient boosting trees, deep neural networks, and automated machine learning models were trained and performance metrics were compared. Data from 4827 patients (4690 patients without LSS: mean age 62.44, range 27–84 years, 62.8% females, and 137 patients with LSS: mean age 50.59, range 30–71 years, 59.9% females) were retrospectively collected. Among the evaluated models, the random forest model demonstrated the highest predictive accuracy with an area under the receiver operating characteristic curve (AUROC) between model prediction and LSS diagnosis of 0.96, a sensitivity of 0.94, a specificity of 0.88, a balanced accuracy of 0.91, and a Cohen's kappa of 0.85. Our results indicate that ML can automate the diagnosis of LSS based on self-reported questionnaires with high accuracy. Implementation of standardized and intelligence-automated workflow may serve as a supportive diagnostic tool to streamline patient management and potentially lower health care costs.

Background: School education is an important part of child's overall growth. But, during the process of attaining school education, children are burdened with heavy back packs which can cause serious health issues. Objectives: The objectives of the study were to assess the knowledge and attitude of school teachers about the ill effects of carrying heavy back packs in children. Materials and Methods: A school based cross sectional study was done among 264 school teachers teaching 6th to 8th standard selected through multistage stratified random sampling technique from selected schools of Kanyakumari district from May 2022 to May 2023. Data collected using a predesigned pre tested and self-administered questionnaire was entered into MS Excel and was analysed using SPSS version 26.0. Results: The results revealed that only 31.8 % of the school teachers knew that the ideal proportion of back packs, 56.4 % knew that the heavy bag packs can cause headache, neck pain and leg pain, 49.2 % knew that it causes shoulder pain and 43.6% knew that it causes back pain in students. For questions on attitude, 20.5 % and 42% of them agreed that heavy back packs can be a reason for tiredness and that it can cause mental stress, respectively. Conclusion: While only half of the participants were knowledgeable about the physical effects of heavy back packs in students, less than half of them were of the attitude that it can have mental and emotional effects.

Pregnant women may experience pain and discomfort during pregnancy, especially in areas such as the lower back and pelvic girdle. Pain in pregnancy is associated with poor quality of life, and because it is a common occurrence, pregnant women may be offered several resources to prevent discomforts throughout pregnancy, such as engaging in physical activity. This study was a meta-analysis of randomised controlled trials (prospectively registered in Prospero, registration number: CRD42023451320) aimed to assess the effects of physical activity during pregnancy on maternal pain and discomfort. We analysed 16 randomised clinical trials. The results of these analyses indicate that women who performed physical activity had significantly less intensity of pain (z = <2.69, p = <0.007; SMD = −0.66, 95% CI = −1.13, −0.18, I2 = <91%, Pheterogeneity = <0.001) and a reduction observed in the disability questionnaire (z = <2.37, p = <0.02; SMD = −0.80, 95% CI = −1.47, −0.14, I2 = <91%, Pheterogeneity = <0.001), and overall reduced general pain (z = <3.87, p = <0.001; SMD = −0.56, 95% CI = −0.84, −0.27, I2 = <86%, Pheterogeneity = <0.001) than women who did not practice physical activity during pregnancy. In conclusion, physical activity during pregnancy could effectively help to diminish pain intensity, reduce disability due to pain, and generally reduce pain. [ABSTRACT FROM AUTHOR]

Background: Condoliase-induced chemonucleolysis is a less invasive treatment for lumbar disc herniation (LDH); however, its long-term clinical outcomes remain unclear. We investigated 2-year clinical outcomes and assess radiographs after chemonucleolysis with condoliase.Methods: We enrolled patients with LDH who received condoliase therapy, with a minimum follow-up period of two years. Sixty-seven patients (44 men, 23 women; mean age, 46.7 ± 18.0 years) were analyzed. Time-course changes in disc height, disc degeneration, and herniation size were assessed. For clinical outcomes assessment, visual analog scale (VAS) scores for leg and back pain and the Oswestry disability index (ODI) were obtained at baseline and the 3-month, 1-year, and 2-year follow-ups. We obtained a questionnaire from these patients at two years to assess satisfaction and recommendation. Condoliase therapy was considered to be effective in patients whose VAS score for leg pain improved by ≥ 50% at 2 years from baseline and who did not require surgery.Results: Condoliase therapy was effective in 51 patients (76.1%). Eight patients (11.9%) required surgery due to ineffectiveness of the therapy. Condoliase therapy was ineffective in five out of six patients with a history of discectomy. The ODI and VAS scores for leg and back pain significantly improved from three months to two years. Of the patients, 80% satisfied with their outcomes, and 85% recommended this therapy. Progression of disc degeneration was observed in 57.1% of patients at three months; however, 30% recovered to baseline at two years. The mean disc height decreased at three months, but recovered slightly at one year and remained stable until two years. No recurrent disc herniation was observed.Conclusions: Chemonucleolysis with condoliase was effective in 78% of patients with LDH for 2 years. Chemonucleolysis-induced disc degeneration was slightly recovered and maintained for two years post-injection. This treatment resulted in high patient satisfaction and recommendations.

Background: Vatari Guggulu is an Ayurvedic Medicine used in the treatment of Vata disorders. It contains Vatari taila (Castor oil), Shuddha gandhaka (purified Sulphur), Haritaki (Terminalia chebula Retz.), Vibhitaki (Terminalia bellirica [Gaertn.] Roxb.), Amla (Emblica officinalis Gaertn) and guggul (Purified Commiphora mukul Hook). As per the Ayurvedic texts, it is widely used clinically in the treatment of rheumatoid arthritis, hip pain, sciatica, gout, joint pain, and burning sensation. However, there are no systematic toxicity studies were performed to scientifically evaluate the safety of Vatari Guggulu. Objectives: The present study was designed to investigate the safety of Vatari Guggulu in acute and 90-days repeated dose oral toxicity as per Organization for Economic Cooperation and Development guidelines 423 and 408. Materials and Methods: During the acute toxicity, Vatari Guggulu was orally administered at a single limit dose of 2000 mg/kg. The mortality and clinical signs were observed for 14 days. Similarly, the 90-days repeated dose toxicity was studied by administering the Vatari Guggulu at a limit dose of 1000 mg/kg. Results: In the acute toxicity, there were no signs of toxicity, and the LD50 was calculated as >2000 mg/kg. During the 90 days of repeated dose toxicity, the Vatari Guggulu at the dose of 1000 mg/kg did not show any signs of toxicity as compared to the control. The hematological, serum biochemical, and urine analysis profile of the Vatari Guggulu at the dose of 1000 mg/kg did not show any significant difference as compared to the control (P > 0.05). Further, the histopathological data of control and Vatari Guggulu-treated rats were found to be normal. Conclusions: It was concluded that the test drug Vatari Guggulu is found to be safe upto 2000 mg/kg in acute toxicity and 1000 mg/kg in 90-days repeated dose oral toxicity study. The NOAEL of Vatari Guggulu is established as 1000 mg/kg/day. [ABSTRACT FROM AUTHOR]

BACKGROUND: Currently there are not enough studies that compared frequent types of collective sports with regard to the prevalence of pain and disability of the lower limb. OBJECTIVE: To determine the prevalence of lower limb pain and disability in team sports players. METHODS: 388 athletes with average age 27.26 ± 4.69, from sports clubs at the national level were included in the study. The Oxford Hip Score was used to determine the prevalence of hip pain. The International Knee Documentation Committee was used to determine the prevalence of knee pain. The Foot and Ankle Disability Index was used to determine the prevalence of ankle pain. RESULTS: Hockey players had a prevalence of hip pain of 97.2% and a 14.3 times higher risk of developing hip pain compared with football and floorball players. Floorball players had a 81.9% prevalence of knee pain, with a 3.8 times higher the risk of knee pain compared with football and hockey. Floorball players had a 62.3% prevalence of ankle pain and a 1.8 times higher the risk of developing ankle pain compared with football and hockey players. CONCLUSIONS: The highest percentage of knee 81.9% and ankle 62.3% pain, as well as the greatest risk of pain, was found among floorball players. Hockey players had the highest prevalence (97.2%) and risk of developing hip pain. [ABSTRACT FROM AUTHOR]

Purpose: A main concern of patients with back problems is pain and its impact on function and quality of life. These are subjective phenomena, and should be probed during the clinical consultation so that the physician can ascertain the extent of the problem. This study evaluated the agreement between clinicians' and patients' independent ratings of patient status on the Core Outcome Measures Index (COMI). Methods: This was an analysis of the data from 5 spine specialists and 108 patients, in two centres. Prior to the consultation, the patient completed the COMI. After the consultation, the clinician (blind to the patient's version) also completed a COMI. Concordance was assessed by % agreement, Kappa values, Bland–Altman plots, Spearman rank, Intraclass Correlation Coefficients and comparisons of mean values, as appropriate. Results: Agreement regarding the "main problem" (back pain, leg/buttock pain, sensory disturbances, other) was 83%, Kappa = 0.70 (95%CI 0.58–0.81). Moderate/strong correlations were found between the doctors' and patients' COMI-item ratings (0.48–0.74; p < 0.0001), although compared with the patients' ratings the doctors systematically underestimated absolute values for leg pain (p = 0.002) and dissatisfaction with symptom state (p = 0.002), and overestimated how much the patient's function was impaired (p = 0.029). Conclusion: The doctors were able to ascertain the location of the main problem and the multidimensional outcome score with good accuracy, but some individual domains were systematically underestimated (pain, symptom-specific well-being) or overestimated (impairment of function). More detailed/direct questioning on these domains during the consultation might deliver a better appreciation of the impact of the back problem on the patient's daily life. [ABSTRACT FROM AUTHOR]

Objective. Determining the effectiveness of physical therapy in the surgical treatment of valgus deformity of the first toe. Methods. The clinical material of the conducted study includes 38 observations, 34 patients (38 operative interventions, 4 patients — on 2 feet. In the control group (CG) there were 16 patients (16 interventions), and in the main group (MG) — 18 patients (22 interventions). All patients who participated in the study had the same diagnosis — hallux valgus II–III degree. All patients received the same type of surgical intervention — a variant Z-shaped osteotomy of the first metatarsal bone according to the Scarf method or Chevron, which was supplemented with osteotomy of proximal phalanges of the I finger to Akin method. Patients were examined with the Visual-Analogue Scale (VAS), the Physiotherapy Clinical Outcome Variables (COVS) Motor Skills Testing Scale, and the American Orthopedic Foot and Ankle Society (AOFAS) Scale (module 2) for the Clinical Evaluation of Foot and Ankle Diseases of the American Foot and Ankle Association. Rehabilitation of MG patients consisted of developed physical therapy (PT) program, which included 4 periods. Rehabilitation included not only massage and exercises for the muscles of the front part of the foot, but also a complex of rehabilitation methods aimed to restore the function of the muscles of both lower limbs, hips and buttocks. PT program for KG consisted only of morning hygienic gymnastics, classical massage and therapeutic exercises to restore function of muscles of the foot and lower leg. Results. Assessment of the condition of patients after the end of PT on the COVS scale helped to conclude that the patients of MG have significantly better indicators of general physical activity than patients of CG. Analysis of the obtained results according to the (AOFAS) Scale confirmed that patients of MG after using developed PT program have statistically better results. Conclusions. The developed PT program significantly accelerate the clinical recovery of function not only the front part of the foot, but also general working capacity of patients. [ABSTRACT FROM AUTHOR]

BACKGROUND AND AIM: Hypoxia, dyspnea, and respiratory function abnormalities take place in patients following coronavirus disease 2019 (COVID-19) due to pulmonary involvement. Moreover, abnormalities in skeletal and respiratory muscles negatively affect exercise capacity. In this study, exercise capacity, respiratory and peripheral muscle strength, pulmonary function, muscle oxygenation, and dyspnea were compared in patients with mild and moderate functional limitations who had post-COVID-19 syndrome. METHODS: In this study, patients with moderate functional limitations with post-COVID-19 syndrome were included on the basis of the Post-COVID-19 Functional Status Scale (PCFS) score 2 mild (n=15) and PCFS score 3 (n=20). Respiratory muscle strength (mouth pressure device), exercise capacity (6-min walk test [6-MWT)], pulmonary function (spirometry), peripheral muscle strength (dynamometer) and muscle oxygenation (Moxy® device), dyspnea during daily living activity [London Chest Activity of Daily Living Scale [LCADL)] were evaluated. RESULTS: Patients with moderate functional limitations with post-COVID-19 syndrome had statistically lower maximal inspiratory and expiratory pressures, 6-MWT distance, and pulmonary function parameters (peak expiratory flow, forced expiratory flow 25%-75%) when compared to those with mild functional limitations (p<0.05). Muscle oxygen saturation, quadriceps femoris muscle strength, LCADL total, and all sub-parameters scores were similar in both groups (p>0.05). CONCLUSIONS: Patients with post-COVID-19 syndrome with moderate functional limitations have less respiratory muscle strength, exercise capacity, and more exertional dyspnea and airway obstruction than those with mild functional limitations. The effects on muscle oxygenation, lower extremity muscle strength, and dyspnea during activities of daily living are similar. Decreased exercise capacity and dyspnea in patients with moderate functional limitations may be associated with decreased respiratory muscle strength. Patients with post-COVID-19 syndrome should be evaluated according to their functional status, and exercise should be planned according to their limitations. [ABSTRACT FROM AUTHOR]

A 27-year-old man presented due to unilateral leg pain. He had a history of diabetes insipidus and panhypopituitarism. Laboratory analysis revealed hormonal undersupply. MRI showed a large contrast medium-absorbing mass in the pituitary gland extending into the hypothalamus. FDG-PET/CT examination revealed a hypermetabolic soft tissue lesion around the left femoral shaft. After biopsy of the lesion, a diagnosis of multisystemic Langerhans cell histiocytosis was made.

Study Design: This was a retrospective observational study that assessed the clinical outcome of ageing patients who received ultrasound-guided (USG) mechanical needling with sterile water injection. In addition, the clinical outcome of age-and gender matched patients randomly selected from patients who received needling with sterile water was compared to the patients injected with lidocaine in a 1:1 ratio. Objective: This present study aimed to explore the clinical effects of USG mechanical needling with sterile water injection for lumbar spinal stenosis (LSS). Methods: The data was extracted from the medical records of ageing patients with LSS who received USG injection at the lumbosacral spine by the first author. Low back pain or axial pain, and leg pain or radicular pain were assessed by the visual analogue scale, and gait ability with walking distance were obtained at six different time points. Results: A total of 4328 medical records were examined. Four thousand two hundred and twenty-eight ageing patients received mechanical needling with sterile water injection and found the efficacy lasted up to 6 months. One hundred patients were compared with 100 patients who received lidocaine injection. Those who received lidocaine had pain returned at 3 months and 6 months post-injection. Conclusions: USG mechanical needling with sterile water injection could help relieve axial and radicular pain for at least 6 months. Removal of calcification and fibrosis as well as reduction of sensitization are all possible mechanisms. [ABSTRACT FROM AUTHOR]
