OBJECTIVE Lumbar discectomy is a frequently performed procedure to treat sciatica caused by lumbar disc herniation. Multiple surgical techniques are available, and the popularity of minimally invasive surgical techniques is increasing worldwide. Clinical outcomes between these techniques may not show any substantial differences. As lumbar discectomy is an elective procedure, patients’ own preferences play an important role in determining the procedure they will undergo. The aims of the current study were to determine the relative preference weights patients apply to various attributes of lumbar discectomy, determine if patient preferences change after surgery, identify preference heterogeneity for choosing surgery for sciatica, and calculate patient willingness to pay for other attributes. METHODS A discrete choice experiment (DCE) was conducted among patients with sciatica caused by lumbar disc herniation. A questionnaire was administered to patients before they underwent surgery and to an independent sample of patients who had already undergone surgery. The DCE required patients to choose between two surgical techniques or to opt out from 12 choice sets with alternating characteristic levels: waiting time for surgery, out-of-pocket costs, size of the scar, need of general anesthesia, need for hospitalization, effect on leg pain, and duration of the recovery period. RESULTS A total of 287 patients were included in the DCE analysis. All attributes, except scar size, had a significant influence on the overall preferences of patients. The effect on leg pain was the most important characteristic in the decision for a surgical procedure (by 44.8%). The potential out-of-pocket costs for the procedure (28.8%), the wait time (12.8%), need for general anesthesia (7.5%), need for hospitalization (4.3%), and the recovery period (1.8%) followed. Preferences were independent of the scores on patient-reported outcome measures and baseline characteristics. Three latent classes could be identified with specific preference patterns. Willingness-to-pay was the highest for effectiveness on leg pain, with patients willing to pay €3133 for a treatment that has a 90% effectiveness instead of 70%. CONCLUSIONS Effect on leg pain is the most important factor for patients in deciding to undergo surgery for sciatica. Not all proposed advantages of minimally invasive spine surgery (e.g., size of the scar, no need of general anesthesia) are necessarily perceived as advantages by patients. Spine surgeons should propose surgical techniques for sciatica, not only based on own ability and proposed eligibility, but also based on patient preferences as is part of shared decision making.

Congenital afibrinogenemia is a rare autosomal recessive blood disorder that accompanies thrombotic complications and is associated with bleeding tendency. The management of these opposing complications remains a challenge. Endovascular treatment (EVT) for peripheral arterial thrombosis has not been described in previous studies. A 57-year-old man with congenital afibrinogenemia developed back pain and left lower leg pain. The cause of the pain was confirmed to be renal infarction and lower extremity arterial thrombosis by Doppler ultrasound and contrast-enhanced computed tomography. He was treated with EVT for the lower extremity arterial thrombosis, leading to an excellent short-term improvement without bleeding.

Objective: To determine if a brief, one-on-one pain neuroscience education (PNE) session delivered by a physical therapist (PT) can influence depression. Methods: A convenience sample of patients with persistent low back pain (LBP) (n = 23) attending PT with moderate to severe depression (Patient Health Questionnaire-9 [PHQ-9]) participated in the study. Patients received a standardized, one-on-one 30-minute PNE session by a PT with pre- and post-intervention measures of low back and leg pain (Numeric Pain Rating Scale [NPRS]), pain catastrophization (Pain Catastrophization Scale [PCS]), pain knowledge (Revised Neurophysiology of Pain Questionnaire [rNPQ] and depression (PHQ-9). Results: Immediately following PNE, all measures improved, with low back and leg pain not being significant (pback = 0.345 and pleg = 0.633), while pain catastrophization (p = 0.047), pain knowledge (p = 0.001) and depression (p = 0.004) reaching significant improvements. The PNE session shifted various patients to lower levels of depression, with 21.8% of the patients’ improvement in depression meeting or exceeding the minimal clinical important difference. Conclusion: PNE may be a safe, clinically effective way to help a subgroup of patients attending PT with depression. More studies are needed to further explore the results from this pilot study.

The aim is to assess the frequency of falls and intrinsic fall risk factors in patients requiring pacemakers. Methodology. The research was conducted from November 2020 to February 2021. Participated patients were hospitalized at the LUHS hospital Kauno Klinikos Department of Cardiology and required heart pacemaker implantation. Total 82 patients participated in the study. The questionnaire was composed by the authors of the research. The study was obtained by the Bioethics Permit of the Medical Academy of LUHS (No. BEC-SL (B) -42). Results. Almost half of the patients fell (45.1%) at least once a year. Elderly patients (65 years and older) are more likely to experience falls than patients under 65 years of age p=0,006. Elderly patients are more often exposed to various internal risk factors of falls: urination at night (82,9 %), weakness (82,9 %), dizziness (76,8 %). Perceived decreased leg muscle strength was found in both women and men (69.6% and 52.8%, respectively, p = 0.002). Patients older than 65 years and therefore

AIM: This was a prospective double-blinded randomized comparative study. Several authors have reported the efficacy of platelets derivatives for spinal union. However, the use of PRP and PRF for bone fusion with TLIF has not been fully explored. METHODS: Standard open TLIF surgery was performed on 80 patients, randomized in three groups, TLIF and local bone were used in 40 patients (control group) and TLIF, local bone, and PRP were used in 20 patients (PRP group) and PRF was used in 20 patients (PRF group). Radiological parameters were assessed by X-ray after 3 months post-operative to evaluate the position of the screws and cage migration and by CT scans at 6 months and 12 months postoperatively. Patients, surgeons, and post-surgical analysis were blinded. RESULTS: VAS scores for lower back pain and leg pain were statistically significant between the three groups preoperatively. The VAS scores of back pain improved after 12 months and were statistically significant (p < 0.001) and the VAS score of leg pain improved compared with preoperatively in the three groups during the 6- and 12-month follow-up postoperatively, however, the three groups, VAS scores for leg pain were not significantly different. After 1-year follow-up, significantly more patients achieved definite fusion, when implanted platelets derivatives compared with the control group, but with no significance regarding fusion rates. CONCLUSION: We advocated using platelet derivative as a fusion enhancer modality which is cost and time saving. It appears to be a complementary step that ensures better outcome for the patients.

Background: An increasing number of lumbar spine conditions are treated surgically. Such intervention, however, is commonly thought to be more effective in addressing leg pain than low back pain. Patient expectations may also contribute to self-reported surgical outcomes. Questions/Purposes: We sought to compare the expectations of patients in 2 groups undergoing lumbar spine surgery: those with predominantly low back pain and those with predominantly leg pain. We also sought to evaluate how these expectations were fulfilled for each group. Methods: We carried out a retrospective analysis of prospectively collected data from a prior study in which patients scheduled for lumbar spine surgery at a single institution completed validated surveys preoperatively and at 2 years postoperatively, including a 20-item survey on expectations for lumbar spine surgery. The patients were enrolled in the study between February 2010 and August 2012, and were divided into 2 cohorts: a “Back > Leg” group that consisted of patients with back pain that was isolated or greater than leg pain, and a “Leg ≥ Back” group that consisted of patients with leg pain that equaled or exceeded back pain. The primary analysis compared composite expectation scores (range, 0–100) between groups. Results: A total of 366 patients were deemed eligible for the study; of these, 162 patients were allocated to the Back > Leg group and 204 patients were allocated to the Leg ≥ Back group. Patients in the Leg ≥ Back group had a greater mean preoperative expectation score compared with those in the Back > Leg group. Multivariate analysis demonstrated that higher preoperative expectations were associated with leg pain symptoms after controlling for disease diagnosis. Both groups reported similar proportions of fulfilled expectations. Conclusion: Patients with predominantly leg pain hold greater preoperative expectations for lumbar spine surgery than do patients with predominantly back pain. That these patient groups reported similar fulfillment of their expectations at 2 years postoperatively illustrates the greater clinical outcomes achieved among patients who presented with predominantly leg pain.

The use of a Viabahn VBX endoprosthesis (W. L. Gore & Associates, Flagstaff, Ariz) to exclude chronically thrombosed inferior vena cava (IVC) filters refractory to exclusion with self-expanding stents was evaluated. The mean duration of TrapEase IVC (Cordis, Milpitas, Calif) implantation was 7.6 years (range, 2-11 years). Symptoms included leg pain, edema, color changes, and back pain. The mean Villalta score and venous clinical severity score were 17 (range, 13-23) and 13 (range, 11-15), respectively. Indirect ultrasound evidence of stent patency was demonstrated at a mean of 8 months after intervention. The mean Villalta score and venous clinical severity score had decreased by 13 and 10, respectively, at a mean of 9.5 months after intervention. Iliocaval reconstruction with Viabahn VBX balloon expandable stent-graft exclusion of chronically thrombosed TrapEase IVC filters is safe, with favorable short-term results.

A 59-year-old man presented to the emergency department with fever and chills that began 6 weeks earlier, when a symptomatic deep vein thrombosis (DVT) of the right posterior tibial vein had been diagnosed. The patient had also noticed word-finding difficulties and mild headache for the week before

OBJECTIVEIn 2017, Michigan passed new legislation designed to reduce opioid abuse. This study evaluated the impact of these new restrictive laws on preoperative narcotic use, short-term outcomes, and readmission rates after spinal surgery.METHODSPatient data from 1 year before and 1 year after initiation of the new opioid laws (beginning July 1, 2018) were queried from the Michigan Spine Surgery Improvement Collaborative database. Before and after implementation of the major elements of the new laws, 12,325 and 11,988 patients, respectively, were treated.RESULTSPatients before and after passage of the opioid laws had generally similar demographic and surgical characteristics. Notably, after passage of the opioid laws, the number of patients taking daily narcotics preoperatively decreased from 3783 (48.7%) to 2698 (39.7%; p < 0.0001). Three months postoperatively, there were no differences in minimum clinically important difference (56.0% vs 58.0%, p = 0.1068), numeric rating scale (NRS) score of back pain (3.5 vs 3.4, p = 0.1156), NRS score of leg pain (2.7 vs 2.7, p = 0.3595), satisfaction (84.4% vs 84.7%, p = 0.6852), or 90-day readmission rate (5.8% vs 6.2%, p = 0.3202) between groups. Although there was no difference in readmission rates, pain as a reason for readmission was marginally more common (0.86% vs 1.22%, p = 0.0323).CONCLUSIONSThere was a meaningful decrease in preoperative narcotic use, but notably there was no apparent negative impact on postoperative recovery, patient satisfaction, or short-term outcomes after spinal surgery despite more restrictive opioid prescribing. Although the readmission rate did not significantly increase, pain as a reason for readmission was marginally more frequently observed.

Background Lumbar spine fusion surgery is traditionally performed with rigid fixation. Because the rigidity is often supraphysiologic, semirigid rods were developed. To the best of our knowledge, a comprehensive evaluation of rod material type on surgical outcomes has yet to be conducted. Methods A systematic review based on PRISMA guidelines was conducted across 3 electronic databases. After examination for inclusion and exclusion criteria, data were extracted from the studies. Results Seventeen studies, including 1399 patients, were included in this review. The mean rigid rod fusion rate is 92.2% and 95.5% for semirigid rods (P = 0.129). The mean improvement in back pain was 60.6% in rigid rods and 71.6% in semirigid rods. The improvement in leg pain was 81.9% and 77.2%, respectively. There were no differences in visual analog scale back pain score (P = 0.098), visual analog scale leg pain score (P = 0.136), or in functional improvement between rigid and semirigid rods (P = 0.143). There was no difference (P = 0.209) in the reoperation rate between rigid rods (13.1%) and semirigid rods (6.5%). There was a comparable incidence of adjacent segment disease (3%), screw fracture (1.7%), and wound infection (1.9%) between rod material types. Conclusions There is a moderate level of evidence supporting that surgical intervention results in high fusion rates regardless of rod material type. Surgical intervention improves back pain, leg pain, and function, with neither material type showing clear superiority. There are comparable rates of reoperation, development of adjacent segment disease, development of mechanical complications, and incidence of infection in both rigid and semirigid rods. Further studies regarding rod material type are warranted.

Aims To study the associations of lumbar developmental spinal stenosis (DSS) with low back pain (LBP), radicular leg pain, and disability. Methods This was a cross-sectional study of 2,206 subjects along with L1-S1 axial and sagittal MRI. Clinical and radiological information regarding their demographics, workload, smoking habits, anteroposterior (AP) vertebral canal diameter, spondylolisthesis, and MRI changes were evaluated. Mann-Whitney U tests and chi-squared tests were conducted to search for differences between subjects with and without DSS. Associations of LBP and radicular pain reported within one month (30 days) and one year (365 days) of the MRI, with clinical and radiological information, were also investigated by utilizing univariate and multivariate logistic regressions. Results Subjects with DSS had higher prevalence of radicular leg pain, more pain-related disability, and lower quality of life (all p < 0.05). Subjects with DSS had 1.5 (95% confidence interval (CI) 1.0 to 2.1; p = 0.027) and 1.8 (95% CI 1.3 to 2.6; p = 0.001) times higher odds of having radicular leg pain in the past month and the past year, respectively. However, DSS was not associated with LBP. Although, subjects with a spondylolisthesis had 1.7 (95% CI 1.1 to 2.5; p = 0.011) and 2.0 (95% CI 1.2 to 3.2; p = 0.008) times greater odds to experience LBP in the past month and the past year, respectively. Conclusion This large-scale study identified DSS as a risk factor of acute and chronic radicular leg pain. DSS was seen in 6.9% of the study cohort and these patients had narrower spinal canals. Subjects with DSS had earlier onset of symptoms, more severe radicular leg pain, which lasted for longer and were more likely to have worse disability and poorer quality of life. In these patients there is an increased likelihood of nerve root compression due to a pre-existing narrowed canal, which is important when planning surgery as patients are likely to require multi-level decompression surgery.

Schwannomas are benign, well-encapsulated and slow growing tumor arising from Schwann cells of the peripheral nerve sheath. They commonly saw in the head and neck, rarely from deep peroneal nerve in the lower limb. We present a case of 42-year-old active national hockey coach, who presented with mild pain and numbness over lateral aspect of left leg for 2 years. The pain was provoked by sporting activities, and was initially relieved by analgesics, until recently, hence his presentation. MRI was done and showed well-defined oval lesion within the deep intermuscular fascia between tibialis anterior and extensor halluces longus muscles. He had an open dissection, and the histology showed a diagnosis of schwannoma. Post-operative healing was uneventful, the pain and numbness improving after 12 months.

The World Health Organisation (WHO) defined low back pain (LBP) as pain or discomfort that is localized between the costal margin and above the inferior gluteal folds, with or without leg pain. In the world, it is estimated that the prevalence of LBP ranges from 1.4% to 20.0%. In 2013, around 24.7% of workers in Indonesia had experienced occupational diseases caused by low back pain. Based on the Riset Kesehatan Dasar (RKD) survey pada in 2018, 31.4% of Indonesians have used traditional medicine, with manual treatment skill, the type of traditional medicine effort, most widely used (65.3%) and one of it is cupping therapy. Cupping (therapy) also named Hijamah. Cupping therapy is one of the alternative medicines that uses vacuum cups on the cupping point of the skin surface. Although the mechanism of action of cupping therapy is still unclear, there are several reported effects of cupping therapy including increasing skin blood flow, changing skin biomechanical properties, increasing the pain threshold, increasing local anaerobic metabolism, reducing inflammation, and modulating the immune system. cellular. According to research conducted by Volpato et al. (2019) demonstrated the effectiveness of cupping therapy in reducing pain perception and improving function in individuals with low back pain.

Introduction Persistent back/and or leg pain is a common outcome after spinal surgery (otherwise known as failed back surgery syndrome [FBSS]). Studies have shown that spinal cord stimulation (SCS) at 10 kHz provides effective analgesia in FBSS patients with both back and leg pain symptoms and in those with predominant back pain. This study is the first to evaluate the therapy in FBSS patients with predominant leg pain. Methods The safety and efficacy of 10 kHz SCS was evaluated in an uncontrolled, open‐label, prospective study of FBSS patients with predominant leg pain in the Netherlands. Follow‐ups were performed at 1, 3, 6, and 12 months post implantation. Results Sixty out of 68 patients (88%) experienced sufficient pain relief during a stimulation trial. Of these, 58 proceeded to permanent implantation of a 10 kHz SCS system. After 12 months of treatment, 80% of patients experienced ≥ 50% reduction in baseline leg pain, and a similar proportion (76%) experienced ≥ 50% reduction in baseline back pain. At least two‐thirds of patients were also leg pain and back pain remitters (visual analog scale [VAS] ≤ 2.5 cm). The therapy was also associated with a general improvement in patients’ quality of life, as measured by secondary outcomes including disability, perception of health improvement, mental well‐being, and satisfaction. A positive impact on opioid consumption was also observed. Conclusions Consistent with previous findings, 10 kHz SCS for the treatment of FBSS patients with predominant radicular symptoms is safe and effective and is associated with improved quality of life.

Some of the improvements in DH, FH, and SLL achieved intraoperatively during lateral lumbar interbody fusion surgery were lost by the postoperative 1-week follow-up. An intraoperative radiograph can predict radiographic and clinical outcomes of the 2-year follow-up. The difference between preoperative DH and intraoperative DH should be4.18 mm.Retrospective cohort study The aim of this study was to evaluate whether the intraoperatively estimated parameters, as calculated on a cross-table lateral radiograph, are maintained in an upright position at discharge and at 2 years postoperatively and to identify the appropriate disc height (DH) to achieve substantial clinical benefit. The amount of correction retained following lateral lumbar interbody fusion (LLIF) surgery had not been reported. A single-center, consecutive series of patients who underwent single-level LLIF with at least 2 years of follow-up were retrospectively reviewed. Upright standardized preoperative, 1-week, and 2-year postoperative radiographs, as well as intraoperative lateral radiographs, were analyzed for DH, foraminal height (FH), and segmental lumbar lordosis (SLL) at the index level. Clinical outcomes were compared between preoperatively and 1 week and 2 years postoperatively. In total, 89 patients were evaluated (mean follow-up, 42.8 months [range, 24–83 months]). DH decreased from 12.5 ± 2.7 mm intraoperatively to 11.7 ± 3.1 mm at 1 week postoperatively, FH decreased from 15.9 ± 3.6 mm to 15.1 ± 3.6 mm, and SLL decreased from 13.6° ± 1.7° to 12.4° ± 1.7°. A linear correlation between intraoperative and 2-year postoperative parameters was found (R2 = 0.552, 0.518, and 0.616, respectively). Clinical outcomes, including back pain, leg pain, and Oswestry Disability Index (ODI), significantly improved 2 years postoperatively. The optimal cutoff point for substantial clinical benefit thresholds for the ODI was a 4.18 mm increase in DH (sensitivity, 64.3%; specificity, 80.3%; area under the curve, 0.793; 95% confidence interval, 0.642–0.855). Some of the improvements in DH, FH, and SLL achieved intraoperatively during LLIF surgery were lost by the postoperative 1-week follow-up. An intraoperative radiograph can predict radiographic and clinical outcomes of the 2-year follow-up. The difference between preoperative DH and intraoperative DH should be4.18 mm. Level of Evidence: 4.

Background The newly proposed low back pain treatment requires case classification according to the pain mechanism (nociceptive, neuropathic or nociplastic) to determine the most effective therapeutic approach. However, there is a lack of objective tools for distinguishing these pain mechanisms. The aim of the study was to identify which symptoms, signs, and standard diagnostic parameters would allow predicting the nociplastic pain (NP) subtype among low back leg pain (LBLP) patients. Methods A retrospective analysis of an LBLP case–control study database was carried out. The presence of NP was assumed if the patient presented with myofascial pain syndrome (MPS) and developed a short-term intensive vasodilatation reaction in the perceived lower leg pain area after provocation by a minimally invasive procedure. Clinical data and standard LBLP diagnostic parameters were analyzed to classify patients as NP (+) vs NP (-). Next, to predict NP probability, logistic regression analysis and a diagnostic classification tree were constructed. Results NP was confirmed in 43.75% of LBLP patients. Women represented 95.24% of all NP (+) patients. The diagnostic classification tree indicated that NP was highly probable if the LBLP subject was female and the result of a positive straight leg raise (SLR) test was lower than 45 degrees. If the SLR test result was greater than or equal to 45 degrees, a negative result on the Bragard test would have diagnostic value. This classification tree was approved to a certain extent in the logistic regression model (deviance residuals, min: −1.8519; 1Q: −0.5551; median: −0.1907; 3Q: 0.6565 and max: 2.1058) but should be verified in a larger group of subjects. Conclusion Female sex, but not clinical data or standard diagnostic parameters, is indicative of nociplastic pain in LBLP patients. More sophisticated statistical methods, based on directly measurable parameters, should be proposed to distinguish NP involvement in LBLP.

Solitary fibrous tumor in the lumbar spine is a rare pathology with non-specific radiographic features, sometimes resulting in misdiagnosis. Our patient was a 41-year old female who presented with low back pain and bilateral leg pain. Initial MRI showed a lesion misdiagnosed for a sequestered disc at the mid L4-5 level, which was subsequently characterized appropriately and treated surgically, with resolution of symptoms. Pathologic diagnosis was most consistent with a solitary fibrous tumor due to STAT 6 and CD 34 reactivity. Long-term follow up is recommended in these patients to monitor tumor recurrence and evidence of metastasis.

Supplemental digital content is available in the text., BACKGROUND Many patients with lower limb edema do not tolerate traditional higher-pressure compression devices and require alternative devices for edema control. METHODS Two systems were evaluated for control of bilateral or unilateral lower limb edema: an elasticized longitudinal stockinette (ELS; EdemaWear; Compression Dynamics, Omaha, Nebraska) and an elasticized tubular bandage (ETB; Tubigrip; Mölnlycke Health Care, Norcross, Georgia). Twenty-five patients were recruited; patients with bilateral edema (n = 12) wore the ELS on one limb, and the ETB on the other. Patients with unilateral edema (n = 13) were randomized to wear either the ELS or ETB. Edema measurements, leg pain, and patient preference were recorded. RESULTS There were 14 females (56%) and 11 males (44%); mean age was 66 years (range, 32-88 years); and mean body mass index was 40.4 kg/m2 (range, 26.1–66.9 kg/m2). Patients with bilateral edema wearing ELS had a foot-to-leg circumference between 25.5 and 42.9 cm pre-ELS that remained essentially unchanged at 2 weeks. The five patients with unilateral edema using ELS had a 24.3– to 43.7-cm circumference pre-ELS and 24.2- to 42.6-cm range at 2 weeks. The patients with bilateral edema using ETBs had a foot-to-leg circumference of 25.5 to 43.7 cm before treatment, unchanged 2 weeks later. The eight patients with unilateral edema using ETB had a 25.4- to 45.3-cm circumference pre-ETB and 24.8– to 42.0-cm range post-ETB. Mean pain levels decreased from 1.0 at week 0 to 0.5 at week 2. More patients preferred ELS (17/23, 78.3%) over ETB (5/23, 21.7%). CONCLUSIONS Both systems were easy to apply and provided low compression without increased pain. The ELS was preferred by more patients (78.3%) than ETB (21.7%).

OBJECTIVEPatients with lumbar disc herniation (LDH) typically present with lower-extremity radiculopathy. However, there are patients who have concomitant substantial back pain (BP) and are considered candidates for fusion. The purpose of this study was to determine if patients with LDH and substantial BP improve with discectomy alone.METHODSThe DaneSpine database was used to identify 2399 patients with LDH and baseline BP visual analog scale (VAS) scores ≥ 50 who underwent a lumbar discectomy at one of 3 facilities between June 2010 and December 2017. Standard demographic and surgical variables and patient-reported outcomes, including BP and leg pain (LP) VAS scores (0–100), Oswestry Disability Index (ODI), and European Quality of Life–5 Dimensions Questionnaire (EQ-5D) at baseline and 12 months postoperatively, were collected.RESULTSA total of 1654 patients (69%) had 12-month data available, with a mean age of 48.7 years; 816 (49%) were male and the mean BMI was 27 kg/m2. At 12 months postoperatively, there were statistically significant improvements (p < 0.0001) in BP (72.6 to 36.9), LP (74.8 to 32.6), ODI (50.9 to 25.1), and EQ-5D (0.25 to 0.65) scores.CONCLUSIONSPatients with LDH and LP and concomitant substantial BP can be counseled to expect improvement in their BP 12 months after surgery after a discectomy alone, as well as improvement in their LP.

A 38-year-old G1P0 presented to the Vascular Lab at 32 weeks gestation for evaluation of persistent left lower extremity edema. The patient reported a 1-month history of left leg pain and swelling after a long car trip. Of note, she had 3 negative lower extremity ultrasounds at outside imaging facilities over the previous 6 weeks. Left lower extremity venous duplex was performed with B-mode, color, power, and spectral Doppler using a linear 12-3 MHz transducer and curvilinear 5-1 MHz transducer. Images were documented using Intersocietal Accreditation Commission Vascular Testing (IAC VT) protocol. Left lower extremity duplex revealed continuous flow in the bilateral common femoral veins. Right common iliac and external iliac vein Doppler waveforms demonstrated spontaneous and phasic flow. Left proximal common iliac and external iliac veins revealed continuous flow. Acute, occlusive deep venous thrombosis (DVT) was identified in the left distal common iliac vein. The left common iliac vein was enlarged, measuring 2.2 cm compared with the contralateral common iliac vein measuring 1.4 cm. Ultrasonographic infrainguinal demonstration of acute DVT is straightforward and usually achievable with standard ICA VT protocol. However, imaging of the proximal pelvic venous circulation can be more elusive, particularly in the pregnant patient. Therefore, it is imperative to assess the spectral Doppler waveforms and to investigate pelvic venous flow. Because of the sonographer’s attention to the common femoral waveforms, additional focused pelvic imaging was performed and located acute, occlusive iliac DVT as the cause of significant edema.

Congenital absence of the inferior vena cava is an uncommon venous anomaly with treatment algorithms consisting of predominately medical management. We present a case of a 36-year-old man with venous ulcers who had failed conservative treatment for recurrent venous ulcers. From a catheter directed approach, we were able to develop an extravascular retroperitoneal space and perform an iliocaval reconstruction with Wallstents. At 1-year postoperatively, his leg pain and edema had resolved, and had achieved resolution of his venous ulceration.

Background. Highly migrated disc herniations are usually localized in the area of pars interarticularis medially to the vertebral pedicle. Removal of disk herniations of this localization is a difficult technical task.The study objective is to demonstrate the effectiveness of the transpedicular endoscopic discectomy in the treatment of patients with highly migrated disc herniations.Materials and methods. The results of treatment of 12 patients with Macnab zone herniations who were in hospital from 2016 to 2018 were analyzed. All patients underwent transpedicular endoscopic sequestrectomy.Results. Leg pain after surgery regressed in all patients from the initial 7.41 points (visual-analog scale) to 0.67 points by the end of the 1st day, and it was 0.35 points a year later. The average level of back pain by VAS before surgery was 5.25, on the 1st day after surgery – 1.25 points, 1 year after – 0.67 points. Neurological disorders completely regressed in 10 (91.6 %) patients, there were a slight residual L4 dermatome hypesthesia in 2 patients, without disrupting their quality of life. The average Oswestry Disability Index before surgery was 69.17, and 1 year after surgery was 14.12. There were no complications and reoperations.Conclusion. Transpedicular endoscopic discectomy allowed us to achieve good treatment results in patients with migration of a lumbar hernia by the pedicle. It can be a safe and effective alternative to the transforaminal or interlaminar endoscopic technique.

Background and purpose — Indication for lumbar disc herniation (LDH) surgery is usually to relieve sciatica. We evaluated whether back pain also decreases after LDH surgery. Patients and methods — In the Swedish register for spinal surgery (SweSpine) we identified 14,097 patients aged 20–64 years, with pre- and postoperative data, who in 2000–2016 had LDH surgery. We calculated 1-year improvement on numeric rating scale (rating 0–10) in back pain (Nback) and leg pain (Nleg) and by negative binomial regression relative risk (RR) for gaining improvement exceeding minimum clinically important difference (MCID). Results — Nleg was preoperatively (mean [SD]) 6.7 (2.5) and Nback was 4.7 (2.9) (p < 0.001). Surgery reduced Nleg by mean 4.5 (95% CI 4.5–4.6) and Nback by 2.2 (CI 2.1–2.2). Mean reduction in Nleg) was 67% and in Nback 47% (p < 0.001). Among patients with preoperative pain ≥ MCID (that is, patients with significant baseline pain and with a theoretical possibility to improve above MCID), the proportion who reached improvement ≥ MCID was 79% in Nleg and 60% in Nback. RR for gaining improvement ≥ MCID in smokers compared with non-smokers was for Nleg 0.9 (CI 0.8–0.9) and ­Nback 0.9 (CI 0.8–0.9), and in patients with preoperative duration of back pain 0–3 months compared with > 24 months for Nleg 1.3 (CI 1.2–1.5) and for Nback 1.4 (CI 1.2–1.5). Interpretation — LDH surgery improves leg pain more than back pain; nevertheless, 60% of the patients with significant back pain improved ≥ MCID. Smoking and long duration of pain is associated with inferior recovery in both Nleg and Nback.

Study Design: Prospective register cohort study. Objectives: The indication for surgery in patients with lumbar spinal stenosis (LSS) is considered to be leg pain and neurogenic claudication (NC). Nevertheless, a significant part of patients operated for LSS have mild leg pain levels defined as leg pain ≤minimally important clinical difference (MICD). Information is lacking on how to inform these patients about the probable outcome of surgery. The objective was to report the outcome of surgery for LSS in patients with a mild preoperative level of leg pain. Methods: A total of 2559 patients operated upon for LSS with preoperative leg pain ≤3 NRS (Numerical Rating Scale) were evaluated for outcome at the 1-year follow-up. NRS for back pain, the Oswestry Disability Index (ODI), and the EuroQol (EQ-5D) were used. Results: In the period 2007 to 2017, we identified 3239 patients (14%) who had mild leg pain (≤3 on the NRS). In this cohort, leg pain increased 0.40 (0.56-0.37) and back pain decreased 1.0 (0.95-1.2) at the 1-year follow up. ODI decreased 11.1 (10.2-11.4) and the EQ-5D increased 0.15 (0.17-0.14). A total of 31% reached successful outcome in terms of back pain, 43% in terms of ODI and 48% in terms of EQ-5D. 63% of the patients were satisfied with the outcome. Conclusion: A minority of patients with mild leg pain levels operated upon for LSS attain MICD for back pain, ODI, and EQ-5D. The results from this study can aid the surgeon in the shared decision-making process before surgery.

STUDY DESIGN Prospective longitudinal cohort. OBJECTIVES The aim of this study was to determine whether functional treadmill testing (FTT) demonstrates differences between patients treated operatively and nonoperatively for adult symptomatic lumbar scoliosis (ASLS). SUMMARY OF BACKGROUND DATA ASLS has become increasingly prevalent as the population ages. ASLS can be accompanied by neurogenic claudication, leading to difficulty walking. FTT may provide a functional tool to evaluate patients with ASLS. METHODS One hundred and eighty-seven patients who underwent nonoperative (n = 88) or operative treatment (n = 99) of ASLS with complete baseline and 2-year post-treatment FTTs and concurrent patient-reported outcomes were identified. FTT parameters included maximum speed, time to onset of symptoms, distance ambulated, time ambulated, and Back and Leg pain severity before and after testing. RESULTS At baseline, patients treated operatively reported worse post-FTT back pain (4.39 vs. 3.45, P = 0.032) than those treated nonoperatively, despite similar ODI, SRS-22 Pain and Activity domain scores. Mean time ambulated (+2.15 vs. -1.20 P = 0.001), pre-FTT back pain (+0.19 vs. -1.60, P

Aim: Osteoporotic vertebral compressive fractures (VCFs) ​are known to be commonly missed in X-rays indicated for pulmonary or heart diseases. In this study, we investigated the underreporting status of VCF in back pain clinic patients when the spine was the focus of interest. Materials and methods: This is a retrospective analysis of 105 female cases (mean: 72 years, range: 55–93 years) from a tertiary hospital in China (facility A, FA). The patients with back and/or leg pain were referred for a spine X-ray. The images were retrieved and transferred to a central reading facility (facility B, FB), where images were double-read by two readers experienced in evaluating osteoporotic vertebral compressive deformity (VCD)/VCF. A qualitative VCD with 40% vertebral body height loss was recorded as minimal, mild, moderate, and severe grades, respectively. A ​VCD coexisted with endplate/cortex fracture (ECF) was VCF. FB readings were considered as the reference. Results: There were 34 true negative cases where FA and FB had a consensus. In 7 cases with minimal VCD, 3 cases with ECF, and 7 cases with minimal or mild VCFs, the FA readings were false negative. No standalone singular moderate or severe VCD/VCF in a patient was missed in FA's reports. In 25 FA reading positive cases with multiple VCFs, one VCF was missed in 8 cases, more than one VCF was missed in 15 cases, and one additional ECF was missed in 2 cases. In 14 cases, FA and FB had VCF number agreement, with the term ‘vertebral fracture’ was used appropriately in FA reports. In 15 cases, FA and FB had agreement in VCF number; however, the appropriate term ‘vertebral fracture’ was not used in FA reports; instead the terms of ‘compressive change’ or ‘wedging change’ were used. In most VCFs, severity grading was not given in FA. In 13 VCFs where grading was reported, all were marked as ‘mild’, including seven mild VCFs, five moderate VCFs, and even one severe VCF. Conclusion: Among the patients with VCD/VCF, the false negative rate among was 23.9% (17/71), but the missed cases were all minimal or mild grades. One or more VCFs were missed in 32.4% (23/71) of the cases with multiple VCFs. Appropriate severity grading was not reported for most cases. The translational potential of this article: The underreporting rate of osteoporotic vertebral compressive fracture in back pain clinic patients in a typical tertiary hospital setting in China compared favorably with literature reports. However, there is a general lack of awareness of vertebral endplate/cortex fracture sign and vertebral fracture severity grading, while minimal and mild VCD with endplate/cortex fracture may have clinical significance. Moreover, after one VCF is spotted in a patient, it is highly advisable to carefully check the whole spine so that multiple VCFs will not be missed.

Objective Presently, there is only limited evidence about the cost-effectiveness of peripheral nerve field stimulation (PNFS) and no evidence to date on the cost-effectiveness of PNFS as an add-on therapy to spinal cord stimulation (SCS). In a multicenter randomized controlled trial, PNFS as add-on therapy to SCS demonstrated clinical effectiveness in treating chronic low back pain in failed back surgery syndrome (FBSS) patients. We report here the cost-effectiveness of PNFS as additional therapy. Materials and Methods Cost-effectiveness analysis was performed from a health-care perspective using the general principles of cost-utility analysis, using empirical data from our multicenter randomized controlled trial on the effectiveness of hybrid SCS + PNFS on low back pain in FBSS patients, who were back pain non-responders to initial SCS-therapy, over a time-horizon of three months. Outcome measures were costs and quality-adjusted life-years (QALYs). Cost and QALYs were integrated using the net monetary benefit (NMB). Differences in costs, effects, and NMB were analyzed using multilevel regression. Uncertainty surrounding the NMB was presented by cost-effectiveness acceptability curves. Results A total of 52 patients implanted with both SCS and PNFS, randomly assigned to a group with PNFS either activated or inactive, completed the controlled part of the study. With mean total costs for the SCS + active PNFS group of euro1813.86 (SD euro109.78) versus euro1103.64 (SD euro123.43) for the SCS + inactive PNFS group at three months, we found an incremental cost-utility ratio of euro25.311 per QALY gained and a probability being cost-effective of more than 80% given a willingness to pay for a QALY of about euro40.000. Conclusions From a Dutch national health-care context, when the willingness to pay threshold is up to 60.000 Euros per QALY, PNFS as an add-on therapy to SCS for the treatment of low back pain in FBSS patients has a high probability of being cost-effective.

Objective This prospective, open-label, multicenter study evaluated the feasibility of spinal cord stimulation (SCS) therapy programming for chronic low back pain that uses multiple electrical pulsed signals (Differential Target Multiplexed). Methods Twenty-five SCS candidates with low back pain equal to or greater than lower limb pain were enrolled at 7 sites in the United States. The subjects evaluated standard and Differential Target Multiplexed programs, each for 4 ± 1 days. A commercially available SCS trial system was used for standard SCS therapy programming. During the trialing of the multiplexed programs, implanted temporary leads were connected to an investigational external trial stimulator system. Results Twenty subjects concluded the study. The mean baseline numeric pain rating scale (NPRS) score for low back pain was 7.4, with a mean age of 62.4 years and mean pain duration of 18.0 years. Significant relief in back pain was observed for both treatments, with significantly better response with multiplexed programming. At the end of the trial period, subjects reported a reduction in their mean NPRS score from baseline to 4.2 after standard programming and to 2.4 after Differential Target Multiplexed programming. The difference between standard and multiplexed programming was significant. The responder rate for low back pain relief was 50% for standard programming and 80% for Differential Target Multiplexed programming. Eighty-five percent of subjects who evaluated both programming approaches preferred Differential Target Multiplexed SCS. Conclusion In this difficult-to-treat patient population, subjects reported significant reduction in chronic back pain when using multiplexed programming. A randomized clinical trial is needed to confirm the results from this feasibility study.

Children with spinal problems present to a wide range of healthcare providers. These providers include the emergency department, their GPs, physiotherapy and the paediatric medical and surgical clinics (including orthopaedics). They may present with a variety of symptoms, but the common complaints are: back pain, leg pain or a change in back shape (spinal deformity). Some children may experience a combination of these problems. A systematic approach to the history and examination with knowledge of the common spinal conditions in children will allow you to select the best investigations. This will maximize the chance of making the correct diagnosis and providing appropriate care. This article aims to give an overview, appropriate for surgeons in the early years of their training.

Patient-reported outcomes measures (PROMs) are critical in evaluating the effectiveness of surgical spine interventions. The Oswestry Disability Index (ODI) is commonly used but tedious to administer routinely. The EuroQol-5 Dimensions (EQ-5D) questionnaire is easier to administer but not traditionally used to measure spine surgical results. This study aimed to investigate the correlation of commonly administered PROMs in lumbar tubular microdecompression patients, and to consider whether ODI could be predicted from remaining PROMs.This study examined 304 index lumbar tubular microdecompression patients with PROMs collected at routine intervals. Spearman correlation coefficients were calculated for each pairwise combination of the following PROMs: ODI, EQ-5D index, leg pain visual analog scale (VAS), low back pain VAS, health state item. Linear regression modeling was conducted to predict ODI from the remaining four PROMs.The patients had a mean age of 65.55 ± 12.97 years and 46.4% were male. Each combination of PROMs demonstrated a statistically significant pairwise correlation (P0.001). ODI showed strong correlation with EQ-5D index (r = -0.77), leg pain VAS (r = 0.73), and back pain VAS (r = 0.65), but weak correlation with health state item (r = -0.33). Forwards stepwise model selection yielded a multiple linear regression model including all four PROMs predictors, with an adjusted R2 of 0.690. There was strong correlation between predicted and observed ODI (r = 0.83, P0.001).ODI can be predicted from EQ-5D, leg and low back pain VAS, and health state items with moderate accuracy. The added utility of capturing ODI routinely may not out-weigh the challenges in doing so.

Background Lumbosciatica is a common condition that affects patients' quality of life. Objective To determine the efficacy of Vojta Therapy and transcutaneous electrical nerve stimulation (TENS) in the treatment of lumbosciatica. Methods A "pre-post" quasi-experimental pilot study was carried out on 12 patients between 31 and 74 years of age who had been diagnosed with lumbosciatica and referred to the Physiotherapy Unit of the Quintanar de la Orden Health Center. Subjects were prescribed either TENS or Vojta, assigned alternately (6:6). All patients received one session of 30 min per day for 15 days. Tests to evaluate pain, disability, functionality, and radiculopathy were performed. Results The differences between pre-post measures and improvement after both treatments were analyzed with nonparametric tests. Significant improvements were noted after both treatments in indices for pain, disability, and flexibility, with the exception of disability after TENS, according to the Roland-Morris test (p = 0.066). Improvements in radiculopathy (Lasegue sign) were only observed with Vojta (p = 0.031). An overall decrease in scores obtained after Vojta was observed with respect to those obtained after TENS (difference V-T): pain according to the Visual Analog Scale (V-T = 2.84; p = 0.033) or Oswestry back pain (V-T = 2.67; p = 0.030) and leg pain tests (V-T = 3.25; p = 0.063); disability according to Oswestry (V-T = 28.33; p = 0.005) and Roland-Morris (V-T = 5.67; p = 0.044); flexibility according to Schober (average gain V-T = 0.43; p = 0.292) and the fingertips to floor distance test (V-T = 7.5; p = 0.016). Conclusions Vojta Therapy led to significantly greater improvements in pain, disability, flexibility, and radiculopathy than TENS. Future studies will require larger samples to confirm these findings.

Background: Myxoma is a rare tumor most frequently discovered in cardiac locations. The present report describes a rare case of extracardiac origin in the femoral vein, initially presenting as leg pain and swelling. Case Presentation: A 40-year-old woman was admitted to our regional hospital with unilateral left leg swelling and pain. She underwent a Duplex scan and CT scan, which revealed a 21 x 25 mm diameter mass in contact with the distal femoral vein, initially diagnosed as a thrombosed sacciform aneurysm. The patient underwent surgical excision of a bulging mass in the vein wall, which was directly closed by running suture. The anatomopathological report concluded with a myxoma. One-year follow-up showed a patent vein without evidence of recurrence of the tumor. Conclusion: Although very rare, peripheral venous myxoma may manifest with common symptoms as leg pain and swelling. Current vascular imaging and complete surgical excision should be performed without delay to allow a precise diagnosis and prevent further complications.

Background Patients’ perceptions/expectations may be a factor behind medical imaging referral rates. Few studies have investigated the beliefs that might drive expectations of medical imaging. Objectives This study examined whether beliefs of young Australian adults with and without impactful low back pain (LBP) concerning medical scans for LBP align with current evidence. It also investigated if these beliefs were associated with clinical factors (history of impactful LBP, history of previous medical scans, LBP-related disability and the presence of leg pain) or sociodemographic factors (sex, education, income). Design Cross-sectional observational study. Methods 78 participants from the Raine Study with a history of impactful LBP and 85 participants with no history of impactful LBP completed a study-specific questionnaire with five statements concerning beliefs about medical imaging for LBP. All statements were not aligned with current evidence about the use of medical imaging in LBP management. Results Only 15–21% (n = 24–34) of the participants held beliefs that were aligned with current evidence. Participants with a university education had slightly more aligned beliefs compared to those whose highest education was completing secondary school. There was no difference in the beliefs of participants based on their history of impactful LBP, or other clinical or sociodemographic factors. Conclusion As beliefs are likely to drive care-seeking behavior, it is notable that most participants’ views about the role of medical imaging for LBP were not aligned with current evidence. Therefore, this suggests a need for community education, especially for those with lower education.

Background: As a newly emerging technique, endoscopic transforaminal lumbar interbody fusion (Endo-TLIF) has become an increasingly popular procedure of interest. The purpose of this study was to introduce a modified Endo-TLIF system and share our preliminary clinical experiences and outcomes in treating lumbar degenerative disease with this procedure.Methods: Ninety-six patients (thirty-seven men and fifty-nine women; mean age 55.85 ± 11.03 years) with lumbar degenerative diseases who underwent Endo-TLIF in our hospital were enrolled. The surgical time, volume of intraoperative blood loss, postoperative hospitalization time and postoperative drainage were documented. Clinical outcomes were evaluated by visual analog scale (VAS) scores, Oswestry Disability Index (ODI) scores, and modified MacNab criteria. Bone fusion was identified through computerized tomography (CT) scans or X-ray during the follow-up period.Results: All patients were followed up for at least 12 months, and the average follow-up time was 17.03 ± 3.27 months. The mean operative time was 136.79 ± 30.14 minutes, and the mean intraoperative blood loss was 53.06 ± 28.89 ml. The mean VAS scores of low back pain and leg pain were 5.05 ± 1.37 and 6.25 ± 1.03, respectively, before surgery, which improved to 2.27 ± 0.66 and 2.22 ± 0.55, respectively, after the operation (P < 0.05). The final VAS scores of low back pain and leg pain were 0.66 ± 0.60 and 0.73 ± 0.66, respectively (P < 0.05). The preoperative ODI score (49.06 ± 6.66) also improved significantly at the 3-month follow-up (13.00 ± 7.37; P < 0.05). The final ODI score was 8.03 ± 6.13 (P < 0.05). There were 10 cases of non-fusion (nine women and one man) at the 12-month follow-up, but no cases of non-union were identified by imaging at the final follow-up.Conclusions: The present study demonstrated satisfactory clinical and radiologic results among patients who received Endo-TLIF treatment from our institution. This indicates that Endo-TLIF is efficient and safe for select patients.

Introduction Work-related musculoskeletal disorders (WMSD) are defined as conditions that the environment contributes significantly to / worsens due to work conditions. WMSD comes second in the source of disability in both developed and developing countries. The aim of this study is to measure the prevalence, patterns, and risk factors of musculoskeletal pain disorders among teachers in the Qassim region, Saudi Arabia. Methods A cross-sectional study was conducted among school teachers in the Qassim region, Saudi Arabia. A validated online Arabic questionnaire was distributed among teachers living in the Qassim region through multiple social networking applications like Facebook, WhatsApp, and Telegram. The questionnaire consisted of Socio-demographic characteristics, the Nordic Musculoskeletal Questionnaire, and a modified version of the Orebro Musculoskeletal Pain Screening questionnaire. Results A total of 503 school teachers were recruited. The proportion of musculoskeletal pain was 91%, and the most common site of pain was back (74.4%), followed by the shoulder (57.5%) and leg (51.5%). The proportion of disabling pain was (80.1%) while the rest was non-disabling pain (19.9%). In the multiple regression model, the predictors of increased disabling pain were back pain, leg pain, neck pain, and those with 51-70 kg weight. In comparison, the predictors of decreased disabling pain were having more than 7 hours of sleep and those with 20-30 classes per week. Conclusion Musculoskeletal pain disorders were widely prevalent among school teachers in the Qassim region, Saudi Arabia. Most teachers considered pain as disabling, which negatively affected their attendance. The back, shoulder, and neck were the most painful sites associated with disabling pain.

Purpose This study aimed to determine whether a fasciectomy for recurrent chronic exertional compartment syndrome of the anterior leg (ant-CECS) after a minimally invasive fasciotomy is safe and beneficial. Methods Demographics and clinical course of patients undergoing a fasciectomy for ongoing exercise-related leg pain (ERLP) after an earlier minimally invasive fasciotomy for ant-CECS were prospectively obtained using questionnaires. Patient-reported severity and frequency of pain, tightness, weakness, cramping, and paresthesia in rest and during exercise were scored before and after surgery. A successful outcome was defined as a self-reported good or excellent result. Results Between January 2013 and March 2019, 24 of the 958 patients evaluated for ERLP were included in the study (15 females; median age, 24 yr; range, 14-37 yr). Intracompartmental pressure values before the minimally invasive fasciotomy and before the fasciectomy were not different. Perioperative findings were fibrotic bands, pseudofascias, or complete fusions of fascial edges. Postoperative superficial wound infections requiring oral antibiotics occurred in four legs. After rehabilitation, the total symptom scores during exercise and resting conditions decreased threefold compared with preoperatively (exercise, 55 ± 5 to 17 ± 3, P < 0.001; rest, 30 ± 4 to 10 ± 2, P < 0.001). All cardinal symptoms decreased significantly, but the largest improvements were reported for pain and tightness. At follow-up (median, 12 months; range, 2-65 months), 79% of patients reported a successful outcome, whereas 75% had returned to physical activity. Conclusion An anterior fasciectomy with associated treatment of correlated pathologies can be safe and beneficial in patients with ongoing ERLP who previously underwent a minimally invasive fasciotomy for ant-CECS.

BACKGROUND Spinal cord stimulation (SCS) is a well-established treatment for chronic intractable pain of the trunk and/or limbs; however, low back pain (LBP) is difficult to treat using traditional SCS. Differential Target Multiplexed spinal cord stimulation (DTM SCS) is an advanced approach inspired from animal studies demonstrating improved pain-related behavior and pain-relevant biological processes. OBJECTIVE The purpose of this study was to compare the effectiveness of DTM SCS and traditional SCS in treating chronic LBP and leg pain (LP). METHODS This prospective, postmarket randomized controlled trial compared DTM SCS to traditional SCS in patients with chronic LBP and LP. Primary end point was LBP responder rate (percentage of subjects with ≥ 50% relief) at 3 months. Noninferiority and superiority were assessed. Other outcomes included mean change in back and leg pain, responder rates, disability, global health, satisfaction, and safety profile throughout the 12-month follow-up. RESULTS One hundred twenty-eight subjects were randomized across 12 centers (67 DTM SCS and 61 traditional SCS). Of the 94 patients implanted, 46 subjects in each group completed the 3-month assessment. LBP responder rate of 80.1% with DTM SCS was superior to 51.2% with traditional SCS (p = 0.0010). Mean LBP reduction (5.36 cm) with DTM SCS was greater than reduction (3.37 cm) with traditional SCS (p

Objective We report a case of cauda equina syndrome related to the use of fibrin glue dural sealant "TISSEEL". Background Incidental durotomy (ID) is not uncommon in revision spinal surgery. Augmentation of the dural repair after primary closure is gaining popularity. The use of dural sealants is not risk-free. Method A 65-year old man who underwent revision lumbar decompression surgery developed postoperative cauda equina syndrome. He had urinary retention, bilateral leg pain and perianal numbness on the third postoperative day. We believe this complication was related to the use of fibrin glue to manage an ID. Result After the urgent surgical removal of the fibrin glue patch, the patient fully recovered with no residual neurological deficit. Conclusion Cauda equina syndrome development is a potential complication after the use of fibrin glue to augment intraoperative ID. Surgeons should be aware of this potential risk so it can be managed in a timely fashion.

Background Low back pain is a common presentation among pregnant women. Case This case report highlights two women who developed excessive low back radicular nerve symptoms during pregnancy as the initial presentation of proximal venous thromboembolism. Conclusion The use of Doppler ultrasound imaging or magnetic resonance imaging is suggested for women presenting with severe clinical symptoms of radicular low back or leg pain in pregnancy to rule out thromboembolism and guide patient management.

OBJECTIVE: Different approaches in neuromodulation have been used to treat chronic low back pain in failed back surgery syndrome (FBSS) patients. We previously randomized 52 FBSS patients to be treated with spinal cord stimulation (SCS) and additional peripheral nerve field stimulation (PNFS) or SCS alone. At three months, we found a significant reduction of back pain in the PNFS-SCS group compared to the SCS group. In the subsequent open phase part of the study, all patients received optimal SCS and PNFS simultaneously. Here, we present the 12-month follow-up data on back and leg pain.MATERIALS AND METHODS: Data regarding back and leg pain, function, quality of life, patient satisfaction, anxiety and depression, and use of medication were collected by analyzing patients' questionnaires at 12 months and compared with data collected at baseline. Data were analyzed using multilevel regression models.RESULTS: A combined group of 50 subjects completed the 12-month follow-up. Back pain, measured on a 100-mm visual analog scale (VAS), significantly decreased over this period by 30.0 mm (95% CI: [-37.7/-22.4]; p CONCLUSIONS: At 12-month follow-up, PNFS in addition to SCS continues to provide a statistically significant and clinically relevant relief of low back pain in FBSS patients in whom SCS alone is effective for relief of leg pain only.

A 53-year-old man presented with 2-day history of acute pain, swelling and bluish discoloration of his left lower limb (figure 1). He did not have chest pain, shortness of breath or palpitation. Vital signs were within normal limits and the dorsalis pedis and posterior tibial pulses were palpable. Muscle compartments of the thigh and leg were tense and tender. The thigh and leg pain were exacerbated by knee and ankle motions, respectively. Figure 1 The clinical photo of both lower limbs of the patient. What would …

The purpose of this study was to clarify the clinical impact of sarcopenia on the outcome of minimally invasive lumbar decompression surgery. The records of 130 patients who were >65 years and underwent minimally invasive lumbar decompression surgery were retrospectively reviewed. We collected the Japanese Orthopaedic Association (JOA) score before surgery and at the final follow-up and measured appendicular muscle mass using bioimpedance analysis, hand-grip strength and gait speed. We diagnosed the patients with sarcopenia, dynapenia and normal stages using the European Working Group on Sarcopenia in Older People definition and used cutoff thresholds according to the algorithm set by the Asian Working Group for Sarcopenia. The average age of patients undergoing surgery was 76.9 years old. The JOA score improved from 12.6 points preoperatively to 24.3 points at final follow up. The prevalence of the sarcopenia, dynapenia and normal stages was 20.0, 31.6 and 43.8%. Clinical outcomes, such as JOA score, JOA score improvement ratio, visual analog scale for low back pain, leg pain and numbness, were not significantly different among each group. Multiple regression analysis showed that preoperative JOA score and low physical performance (low gait speed) were independently associated with poor clinical outcomes. The JOA score improved after minimally invasive lumbar decompression surgery even when the patients were diagnosed as being at different stages of sarcopenia. Low physical performance had the greater clinical impact on the clinical outcome of lumbar surgery than low skeletal muscle index.

To measure and compare the total and normalised tibial nerve movements during forward bending in patients with and without failed back surgery syndrome (FBSS) and persistent leg pain following anatomically successful lumbar decompression surgery and demonstrated no psychological stress. Nerve pathomechanics may contribute to FBSS with persistent leg pain following anatomically successful lumbar decompression surgery. Tibial nerve movement during forward bending was measured in two groups of patients following anatomically successful lumbar decompression surgery. FBSS group (N = 37) consisted of patients with persistent leg pain following lumbar surgery, and non-FBSS (N = 37) were patients with no remaining leg pain following lumbar surgery. Total and normalised tibial nerve movement at the popliteal fossa was measured by a previously validated ultrasound imaging technique and compared between the two groups, and also between the painful and non-painful leg within the FBSS group. Both the mean total and normalised tibial nerve movement were significantly decreased in the FBSS group in both legs when compared to the non-FBSS group (P

Study Design: Retrospective cohort study. Objectives: Discectomy alone or discectomy with fusion have been 2 polarized options in the management of large lumbar disc herniations presenting with leg-dominant pain in young patients. The objective of the study was to evaluate the outcomes of discectomy in young patients with large central lumbar disc herniation (CLDH) presenting with predominant leg pain. Material and Methods: Young patients (Results: Ninety patients fulfilled the inclusion criteria. The mean age of patients was 34.9 years (range 19-45 years). Mean follow-up was 5.09 years (range 2-10 years). The incidence of CLDH in young adults was 30% and incidence among all “operated” lumbar disc herniations was 15.9%. The mean VAS for leg pain improved from 7.48 ± 0.9 to 2.22 ± 0.84 ( P < .05) and the mean ODI changed from 60.53 ± 7.84 to 18.33 ± 6.20 ( P < .05). Fifty-nine patients (65.6%) reported excellent, 25 patients (27.8%) reported good, 3 patients each (3.3%) as fair and poor outcomes respectively. Conclusion: Discectomy alone for CLDH with predominant leg pain is associated with high success rate and low need for a secondary surgical procedure. Patient selection in terms of leg-dominant pain may be the main attribute for lower incidence of recurrence, postoperative back-pain, and instability needing a secondary procedure. Minimally invasive discectomy may provide an added advantage of preserving normal spinal anatomy, thus minimizing the need for primary spinal fusion in these patients.

Background Patients with back-related leg pain exhibit nociceptive and neuropathic characteristics. Few studies have investigated the combination of interventions considering these characteristics. Objectives To investigate if the addition of neurodynamic exercises (EEN) to extension-oriented exercises (EE) promotes additional benefits in individuals with back-related leg pain and a directional preference. Methods Patients will be randomized to either EE or EEN. Patients from both groups will receive 7 sessions over 3 weeks. Low back and leg pain, function, quality of life, disability, and global perceived effect will be evaluated at baseline, 3 weeks after randomization and 1-month follow-up. A linear mixed model will be used for outcomes analysis.

Objective To examine the results of an anular closure device for prevention of lumbar disc reherniation in daily routine practice. Methods Fifty patients with large anular defects were treated with limited discectomy and a bone‐anchored anular closure device. The device physically occludes the defect in the anulus fibrosus and is intended for prevention of lumbar disc reherniation. Pain scores on a visual analogue scale, back function on the Oswestry Disability Index, and neurological status were noted. Symptomatic reherniation and reoperation rates were assessed at each follow‐up. Surgical findings and complications, device‐related and/or procedure‐related, were recorded. Follow‐up was 6, 12, 26, and 52 weeks. Results Mean anular defect height/width was 4.6 mm/10.1 mm. The overall symptomatic reherniation and reoperation rate was 2%. During the 1‐year follow‐up period, mean back pain decreased from 43 to 8 (P < 0.001), leg pain decreased from 71 to 4 (P < 0.001), and the Oswestry Disability Index decreased from 46 to 5 (P < 0.001). Among 15 patients with preoperative neurological deficits, improvements in neurological function were noted in 14 (93%). There were no serious device‐related complications. Conclusions The presented study shows promising early results in using the anular closure device. The procedure is safe with significantly fewer reherniations than for patients with large anular defects without anular closure. Further studies with longer follow‐up periods are warranted to prove these findings for long‐term outcomes.

ObjectiveThis study aimed to compare intraoperative lower back pain and leg pain, surgical time, and intraoperative X-ray dose in patients offered local infiltration anesthesia or continuous epidural anesthesia for transforaminal endoscopic spine system (TESSYS) surgery.MethodsA total of 98 patients who received TESSYS treatment for single-segmental lumbar disc herniation were included, and were randomly divided into two groups: group A (49 cases; local infiltration anesthesia) and group B (49 cases; continuous epidural anesthesia). Surgical duration, intraoperative X-ray dose, and visual analog scale (VAS) scores of lower back pain and leg pain before surgery, during surgery, and 48 h after surgery were recorded and compared.ResultsAfter surgery, the VAS scores of both lower back pain and leg pain decreased in group A, and similar findings were found in group B. Group B had a shorter surgical duration, lower intraoperative X-ray dose, and lower intraoperative VAS scores of lower back pain and leg pain compared with group A.ConclusionCompared with local infiltration anesthesia, continuous epidural anesthesia was more effective for pain relief during TESSYS for single-segmental lumbar disc herniation, and also contributed to a shorter surgical duration and lower X-ray exposure.

There are cases when symptoms are available but no abnormal stenosis is found in MRI and vice versa. Axial-loaded MRI has been shown that it can demonstrate more accurately the real status of spinal canal stenosis than conventional MRI. This is the first time we applied a new system that we have recreated from the original loading frame system in order to fit with the demands of Vietnamese people. Sixty-two patients were selected from Phu Tho Hospital in Phu Tho Province, Vietnam, who fulfilled the inclusion criteria. The Anterior-posterior diameter (APD), Dura Cross-sectional Area (DSCA) in conventional MRI and axial loaded MRI, and changes in APD and DCSA were determined at the single most constricted intervertebral level. The APD and DCSA in axial loaded MRI had very good significant correlations with VAS for back pain (rs=0.83, 0.79), leg pain (rs=0.69, 0.57) and JOA score (rs=0.70, 0.65). APD and DCSA in axial loaded MRI significantly correlated with the severity of symptoms. Our axial loading MRI provides more valuable information than the conventional MRI for assessing patients with LSCS.

BACKGROUND Diffuse fasciitis with psoriatic arthritis on magnetic resonance imaging (MRI) has not been previously described in childhood. Here we present the first case report of a pediatric patient developing fasciitis, beyond plantar fasciitis, with psoriatic arthritis. CASE SUMMARY An 11-year-old female was admitted with the complaints of psoriatic rash on the body associated with severe pain in the lower extremities and arthritis in the right knee. Psoriasis was confirmed by skin biopsy, she diagnosed with juvenile psoriatic arthritis. Diagnostic tests did not indicate any pathology except MRI. MRI of the femur and tibia revealed that high-signal inflammatory changes in the subdermal fascia. These findings led to a diagnosis of psoriatic fasciitis. Methotrexate was given for 3 mo but the patient showed no response to therapy; therefore, etanercept was added. However, there was no response to treatment. Etanercept was switched to adalimumab at the sixth month of therapy. Clinical improvement started with therapy of adalimumab within one month. Fasciitis finding in MRI disappeared at seventh months on adalimumab therapy. She has no complaint for two years with adalimumab. CONCLUSION The most effective imaging method is MRI and adalimumab may be the best choice of treatment for psoriatic fasciitis. © The Author(s) 2019.
