BACKGROUND: Lumbar degenerative disease is a common disease in middle-aged and elderly patients. Traditional lumbar spine surgery is more traumatic and takes a long time to recover after surgery. In recent years, spinal endoscopic technology has achieved great development, and endoscopic transforaminal lumbar interbody fusion, as a new treatment for lumbar degenerative diseases, is worth promoting in patients with indications for lumbar degenerative diseases because of the advantages of less trauma, shorter recovery time, less postoperative pain, and less bleeding. OBJECTIVE: To review the research progress of endoscopic transforaminal lumbar interbody fusion in lumbar degenerative diseases, review the occurrence, development, advantages, limitations, and development trend of endoscopic transforaminal lumbar interbody fusion. METHODS: The first author used a computer to search PubMed, Web of Science and Wanfang databases for the literature published from 2010 to 2022. Key words were “endoscopic lumbar fusion, lumbar degenerative disease, minimally invasive spine” in Chinese and English. Duplicate, poor quality and irrelevant articles were excluded for review analysis. RESULTS AND CONCLUSION: (1) Degenerative diseases of the lumbar spine are the pathological basis of disc herniation, spinal stenosis, and vertebral slippage, and are the main cause of discogenic lower back pain. Endoscopic transforaminal lumbar interbody fusion is a novel technique for the treatment of degenerative diseases of the lumbar spine. (2) In recent years, endoscopic lumbar spine surgery has evolved from simple decompression to simultaneous decompression and fusion, with satisfactory short-term results. Microscopic fusion and flexible anesthesia are the greatest highlights of this technique, which has the advantages of less surgical trauma, less bleeding, shorter hospital stay, less postoperative pain, faster recovery, and preservation of the posterior spinal structures, but because of the need for repeated intraoperative fluoroscopy, the relatively high radiation exposure to the surgeon and the patient, as well as the higher requirements for the surgeon’s operating skills. (3) The use of endoscopic transvertebral foramina for the treatment of degenerative lumbar spine disease is now considered to be a potentially effective novel treatment compared to conventional surgery. In previous studies of endoscopic transforaminal lumbar interbody fusion, there were some shortcomings in the use of large amounts of saline to flush the surgical site intraoperatively causing occult blood loss, and these occult blood losses could not be calculated, which was not included in the relevant literature. Second, because fewer hospitals can perform endoscopic transforaminal lumbar interbody fusion and lack the support of large samples and long-term follow-up evidence, its long-term efficacy still needs further study.

Background: Chiropractors use a variety of therapeutic interventions in clinical practice. How the selection of interventions differs across musculoskeletal regions or with different patient and provider characteristics is currently unclear. This study aimed to describe how frequently different interventions are used for patients presenting for chiropractic care, and patient and provider characteristics associated with intervention selection. Methods: Data were obtained from the Chiropractic Observation and Analysis STudy (COAST) and Ontario (O-COAST) studies: practice-based, cross-sectional studies in Victoria, Australia (2010–2012) and Ontario, Canada (2014–2015). Chiropractors recorded data on patient diagnosis and intervention selection from up to 100 consecutive patient visits. The frequency of interventions selected overall and for each diagnostic category (e.g., different musculoskeletal regions) were descriptively analysed. Univariable multi-level logistic regression (provider and patient as grouping factors), stratified by diagnostic category, was used to assess the association between patient/provider variables and intervention selection. Results: Ninety-four chiropractors, representative of chiropractors in Victoria and Ontario for age, sex, and years in practice, participated. Data were collected on 7,966 patient visits (6419 unique patients), including 10,731 individual diagnoses (mean age: 43.7 (SD: 20.7), 57.8% female). Differences in patient characteristics and intervention selection were observed between chiropractors practicing in Australia and Canada. Overall, manipulation was the most common intervention, selected in 63% (95%CI:62–63) of encounters. However, for musculoskeletal conditions presenting in the extremities only, soft tissue therapies were more commonly used (65%, 95%CI:62–68). Manipulation was less likely to be performed if the patient was female (OR:0.74, 95%CI:0.65–0.84), older (OR:0.79, 95%CI:0.77–0.82), presenting for an initial visit (OR:0.73, 95%CI:0.56–0.95) or new complaint (OR:0.82, 95%CI:0.71–0.95), had one or more comorbidities (OR:0.63, 95%CI:0.54–0.72), or was underweight (OR:0.47, 95%CI:0.35–0.63), or obese (OR:0.69, 95%CI:0.58–0.81). Chiropractors with more than five years clinical experience were less likely to provide advice/education (OR:0.37, 95%CI:0.16–0.87) and exercises (OR:0.17, 95%CI:0.06–0.44). Conclusion: In more than 10,000 diagnostic encounters, manipulation was the most common therapeutic intervention for spine-related problems, whereas soft tissue therapies were more common for extremity problems. Different patient and provider characteristics were associated with intervention selection. These data may be used to support further research on appropriate selection of interventions for common musculoskeletal complaints. [ABSTRACT FROM AUTHOR]

Background: Surgery involving implantable devices is widely used to solve several health issues. National registries are essential tools for implantable device surveillance and vigilance. In 2017, the European Union encouraged Member States to establish "registries and databanks for specific types of devices" to evaluate device safety and performance and ensure their traceability. Spine-implantable devices significantly impact patient safety and public health; spine registries might help improve surgical outcomes. This study aimed to map existing national spine surgery registries and highlight their features and organisational standards to provide an essential reference for establishing other national registries. Methods: A scoping search was performed using the Embase, PubMed/Medline, Scopus, and Web of Science databases for the terms "registry", "register", "implantable", and all terms and synonyms related to spinal diseases and national registries in publications from January 2000 to December 2020. This search was later updated and finalised through a web search and an ad hoc survey to collect further detailed information. Results: Sixty-two peer-reviewed articles were included, which were related to seven national spine registries, six of which were currently active. Three additional active national registries were found through the web search. The nine selected national registries were set up between 1998 and 2021. They collect data on the procedure and use patient-reported outcome measures (PROMs) for the follow-up. Conclusion: Our study identified nine currently active national spine surgery registries. However, globally accepted standards for developing a national registry of spine surgery are yet to be established. Therefore, an international effort to increase result comparability across registries is highly advisable. We hope the recent initiative from the Orthopaedic Data Evaluation Panel (ODEP) to establish an international collaboration will meet these needs. [ABSTRACT FROM AUTHOR]

Background: Degenerative spine conditions are common and frequent clinical diseases, and adjacent segment disease (ASD) after spinal fusion (SF) is a common complication after spinal fusion (SF). In this study, we established an animal model of ASD after interbody fusion to observe the morphologic changes of adjacent segment (AS) disks and to determine the expression and significance of tumor necrosis factor-alpha (TNF-α) and interleukin-1beta (IL-1β) in ASD tissues to provide a good experimental basis and reference for clinical prevention and treatment of ASD after interbody fusion. Methods: Thirty-six male and female New Zealand rabbits weighing 2.0–2.5 kg were randomly divided into control group (group A) and experimental groups (groups B, C, and D), with 9 rabbits in each group, of which groups B, C, and D were the 4-, 8-, and 12-week groups, respectively. Autologous iliac bone grafts were used as the bone graft material. In the experimental groups, a SF was performed on the C2–C3 intervertebral space. The C3–4 adjacent segments were examined. In the experimental group, the animals were subjected to gross observation, X-ray examination, hand touch inspection, and micro-computed tomography (micro-CT) 4, 8, and 12 weeks after surgery. The micromorphologic changes of the cervical disks in the segments of the control group and experimental groups were observed under light microscopy. Immunohistochemistry and Western blotting were used to detect the expression of TNF-α and IL-1β in the AS tissues after interbody fusion in the control and experimental groups. Results: The measurement data of the rabbit cervical spine bony structures indicated that the length of the vertebral body and the sagittal diameter of the lower end of the vertebral body decreased gradually from the 2nd–6th cervical vertebrae, and the difference was statistically significant (P < 0.05). The difference in the transverse diameter of the lower end of the vertebral body was not statistically significant (P > 0.05), the change in the oblique diameter of the lower end of the vertebral body fluctuated, and the difference was statistically significant (P < 0.05). The fusion rate of the cervical spine by hand touch inspection was 22.2% (2/9), 55.6% (5/9), and 88.9% (8/9) in groups B, C, and D, respectively. The differences in bone volume-to-total volume (BV/TV) and X-ray scores were statistically significant in groups B, C, and D (P < 0.05). Significant degeneration occurred in groups B, C, and D compared with group A. The expression of TNF-α and IL-1β in the intervertebral disk tissue was significantly higher in groups B, C, and D compared with group A (P < 0.05), and increased with time. Conclusion: In this study, an animal model of ASD after interbody fusion fixation in rabbits was successfully established. Postoperative imaging and hand touch inspection showed a positive correlation between the amount of new intervertebral bone and the degree of fusion with time. The results of immunohistochemistry and Western blot showed that TNF-α and IL-1β were highly expressed in the AS tissues of the experimental group after interbody fusion, and the degree of disk degeneration was positively correlated with the time after interbody fusion.

Background: The aim of this study was to comprehensively evaluate the short-term clinical efficacy and safety of unilateral biportal endoscopic transforaminal lumbar interbody fusion (UBE-TLIF) versus minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) for the treatment of lumbar degenerative diseases by meta-analysis. Methods: A computer-based search of PubMed, Embase, Web of Science, Cochrane Database, China National Knowledge Infrastructure (CNKI), Wanfang Database, and Chinese Science and Technology Journal Database (VIP) was conducted from the inception of the each database to April 2023. The searched literature was then screened according to strict inclusion and exclusion criteria. The critical data were extracted and analyzed using Review Manager software5.4.1. Pooled effects were calculated on the basis of data attributes by mean difference (MD) or odds ratio (OR) with 95% confidence interval (CI). The Newcastle–Ottawa Scale was used to assess the quality of the studies. Results: A total of 13 studies and 949 patients met the inclusion criteria for this meta-analysis, 445 in the UBE-LIF group and 504 in the MIS-TLIF group. UBE-TLIF was superior to MIS-TLIF in terms of intraoperative blood flow, postoperative drainage flow, duration of hospital stay, VAS score for low back pain and ODI score, but the operative time was longer than MIS-TLIF group. There were no significant differences between the two groups in terms of total complication rate, modified Macnab grading criteria, fusion rate, VAS score of leg pain, lumbar lordosis, intervertebral disk height. Conclusion: Both UBE-TLIF and MIS-TLIF are effective surgical modalities for the treatment of degenerative lumbar spine diseases. They have similar treatment outcomes, but UBE-TLIF has the advantages of less intraoperative blood loss, shorter postoperative hospital stay, and faster recovery. Trial registration: This study has been registered at INPLASY.COM (No. INPLASY202320087). [ABSTRACT FROM AUTHOR]

Accurate image segmentation plays an essential role in diagnosing and treating various spinal diseases. However, traditional segmentation methods often consume a lot of time and energy. This research proposes an innovative deep‐learning‐based automatic segmentation method for spine magnetic resonance imaging (MRI) images. The proposed method DAUNet++ is supported by UNet++, which adds residual structure and attention mechanism. Specifically, a residual block is utilized for down‐sampling to construct the RVNet, as a new skeleton structure. Furthermore, two novel types of dual channel and spatial attention modules are proposed to emphasize rich feature regions, enhance useful information, and improve the network performance by recalibrating the characteristic. The published spinesagt2wdataset3 spinal MRI image dataset is adopted in the experiment. The dice similarity coefficient score on the test set is 0.9064. Higher segmentation accuracy and efficiency are achieved, indicating the effectiveness of the proposed method. [ABSTRACT FROM AUTHOR]

Background: The optimal timing for hemivertebra resection remains controversial. Early intervention before 3 years of age seems being able to get better correction with less fusion segments. However, it was also reported that early surgery may be associated with more complications. The purpose of this study is to investigate correction outcomes and complications of delayed hemivertebra resection (between 3 and 5 years of age), in comparison with earlier surgery (before 3 years of age). Methods: Patients who had undergone thoracolumbar hemivertebra resection at a single level before 5 years of age and had more than 5 years of follow-up were reviewed. Twenty-four patients had hemivertebra resection surgery below 3 years of age (early surgery, Group E), and 33 patients received surgery between 3 and 5 years of age (delayed surgery, Group D). Radiographs from preoperative, immediately postoperative, and the latest follow-up visits were reviewed to investigate the correction outcomes. Complications were recorded and compared between these two groups. Results: The patients of Group E had shorter operation time and less blood loss than those of Group D (P = 0.003 and P = 0.006). Notably, the fusion segments were 2.3 ± 0.7 and 3.1 ± 1.2 in group E and group D (P = 0.005), respectively, indicating group E averagely saved 0.8 motion segments. At the time of surgery, group E had smaller main curve magnitude either in the coronal or in the sagittal plane than group D and experienced similar correction rates of scoliosis (83.3 ± 21.6% vs. 81.2 ± 20.1%, P = 0.707) and kyphosis (65.1 ± 23.8% vs. 71.7 ± 24.9%, P = 0.319). However, group E had relatively higher complication rates than group D and relatively greater correction loss in either coronal or sagittal plane during follow-up. Conclusions: Hemivertebra resection resulted in similar correction results in both age groups. However, the rate of complications was lower for Group D than Group E. Thus, for non-kyphotic hemivertebra, surgery may be delayed till 3 to 5 years of age. [ABSTRACT FROM AUTHOR]

Background: In previous studies, many imaging analyses have been conducted to explore the changes in the intervertebral disc degeneration (DD), facet joint osteoarthritis (FJOA), L4 inclination angle (L4IA), pelvis-related parameters, lumbar lordosis (LL), and paravertebral muscle (PVM) in the occurrence and development of degenerative spinal diseases via measuring the X-ray, CT, and MRI data of clinical patients. However, few studies have quantitatively investigated the pelvic parameters and the degree of spine degeneration in patients with degenerative lumbar spondylolisthesis (DLS) and isthmic lumbar spondylolisthesis (ILS). This study discusses the changes in the imaging parameters of DLS, ILS, and a control group; explores the correlation between different measurement parameters; and discusses their risk factors. Methods: We evaluated 164 patients with single L4-L5 grade 1 level degenerative lumbar spondylolisthesis (DLS group), 161 patients with single L4-L5 grade 1 level isthmic lumbar spondylolisthesis (ILS group), and 164 patients with non-specific back pain (control group). The grades of DD and FJOA as well as the percentage of the fat infiltration area (%FIA) of multifidus muscle (MM) at the L4-L5 level were measured via CT and MRI. Lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT), the L4 inclination angle (L4IA), and sacral slope (SS) were measured via X-ray film, and the differences among the DLS group, ILS group, and control group were analyzed. Furthermore, the risk factors related to the incidences of the DLS and ILS groups were discussed. Results: First, the pelvis-related parameters of DLS and ILS patients were 51.91 ± 12.23 and 53.28 ± 11.12, respectively, while those of the control group were 40.13 ± 8.72 (p1 < 0.001, p2 < 0.001). Lumbar lordosis (LL) in DLS patients (39.34 ± 8.57) was significantly lower than in the control group (44.40 ± 11.79, p < 0.001). On the contrary, lumbar lordosis (LL) in the ILS group (55.16 ± 12.31) was significantly higher than in the control group (44.40 ± 11.79, p < 0.001). Secondly, the three groups of patients were characterized by significant variations in the L4 inclination angle (L4IA), disc degeneration (DD), facet joint osteoarthritis (FJOA), pelvis-related parameters, and paravertebral muscle (PVM) (p < 0.05). Finally, logistic regression suggests that the L4IA, FJOA, and PT may be risk factors for the occurrence of DLS, and the occurrence of ILS is correlated with the L4IA, FJOA, DD, PT, and LL. Conclusions: Compared with the control group, there are changes in pelvic parameters, the L4IA, LL, DD, FJOA, and PVM in DLS and ILS patients, and the degree is different. The parameters within the same group are related to each other, and DLS and ILS have different risk factors. The mechanical stability of the spine is affected by the parameter and angle changes, which may be of great significance for explaining the cause of spondylolisthesis, evaluating the health of the lumbar spine, and guiding the lifestyles of patients.

Background: Spinal lesions in pediatric chronic recurrent multifocal osteomyelitis/chronic non-bacterial osteomyelitis (CRMO/CNO) can cause permanent sequelae; thus, early recognition of these is vital for management. Objective: To characterize the MR imaging features and patterns of pediatric spinal CRMO/CNO. Materials and methods: This cross-section study received IRB approval. The first available MRI with documented spine involvement in children with CRMO/CNO was reviewed by a pediatric radiologist. Descriptive statistics were used to describe the characteristics of vertebral lesions, disc involvement, and soft tissue abnormality. Results: Forty-two patients were included (F:M, 30:12); median age was 10 years (range 4–17). At diagnosis, 34/42 (81%) had spine involvement. Kyphosis in 9/42 (21%) and scoliosis in 4/42 (9.5%) patients were present at the time of spinal disease recognition. Vertebral involvement was multifocal in 25/42 (59.5%). Disc involvement was found in 11/42 (26%) patients, commonly in the thoracic spine and often with adjacent vertebrae height loss. Posterior element abnormalities were present in 18/42 patients (43%) and soft tissue involvement in 7/42 (17%). One hundred nineteen vertebrae were affected, commonly the thoracic vertebrae (69/119; 58%). Vertebral body edema was focal in 77/119 (65%) and frequently superior (42/77; 54%). Sclerosis and endplate abnormality were present in 15/119 (13%) and 31/119 (26%) vertebrae, respectively. Height loss was present in 41/119 (34%). Conclusion: Chronic non-bacterial osteomyelitis of spine is usually thoracic. Vertebral body edema is often focal at the superior vertebral body. Kyphosis and scoliosis occur in a quarter and vertebral height loss in a third of children at spinal disease recognition. [ABSTRACT FROM AUTHOR]

Background: As a subjective sensation, pain is difficult to evaluate objectively. The assessment of pain degree is largely dependent on subjective methods such as the numeric rating scale (NRS). The PainVisionTM system has recently been introduced as an objective pain degree measurement tool. The purpose of this study was to analyze correlations between the NRS and the current perception threshold (CPT), pain equivalent current (PEC), and quantified pain degree (QPD). Methods: Medical records of 398 subjects who visited the pain clinic in a university hospital from March 2017 to February 2019 were retrospectively reviewed. To evaluate the pain degree, NRS, CPT, PEC, and QPD were measured. Subjects were categorized into two groups: the Pain group (n = 355) and the No-pain group (n = 43). Results: The NRS showed a negative correlation with CPT (R = −0.10, p = 0.054) and a positive correlation with QPD (R = 0.13, p = 0.008). Among various diseases, only spinal disease patients showed a negative correlation between CPT and NRS (R = −0.22, p = 0.003). Additionally, there were significant differences in CPT and QPD between the Pain and No-pain groups (p = 0.005 and p = 0.002, respectively). Conclusions: CPT and QPD measured using the PainVisionTM system could be used to estimate pain intensity and the presence of pain. These parameters would be considered useful for predicting pain itself and its intensity. [ABSTRACT FROM AUTHOR]

Metastatic spinal disease is an advanced stage of cancer patients and often suffer from terrible psychological health status; however, the ability to estimate the risk probability of this adverse outcome using current available data is very limited. The goal of this study was to propose a precise model based on machine learning techniques to predict psychological status among cancer patients with spinal metastatic disease. A prospective cohort study. A total of 1043 cancer patients with spinal metastatic disease were included. The main outcome was severe psychological distress. The total of patients was randomly divided into a training dataset and a testing dataset on a ratio of 9:1. Patients' demographics, lifestyle choices, cancer-related features, clinical manifestations, and treatments were collected as potential model predictors in the study. Five machine learning algorithms, including XGBoosting machine, random forest, gradient boosting machine, support vector machine, and ensemble prediction model, as well as a logistic regression model were employed to train and optimize models in the training set, and their predictive performance was assessed in the testing set. Up to 21.48% of all patients who were recruited had severe psychological distress. Elderly patients (p<0.001), female (p =0.045), current smoking (p=0.002) or drinking (p=0.003), a lower level of education (p<0.001), a stronger spiritual desire (p<0.001), visceral metastasis (p=0.005), and a higher Eastern Cooperative Oncology Group (ECOG) score (p<0.001) were significantly associated with worse psychological health. With an area under the curve (AUC) of 0.865 (95% CI: 0.788–0.941) and an accuracy of up to 0.843, the gradient boosting machine algorithm performed best in the prediction of the outcome, followed by the XGBooting machine algorithm (AUC: 0.851, 95% CI: 0.768–0.934; Accuracy: 0.826) and ensemble prediction (AUC: 0.851, 95% CI: 0.770–0.932; Accuracy: 0.809) in the testing set. In contrast, the AUC of the logistic regression model was only 0.836 (95% CI: 0.756–0.916; Accuracy: 0.783). Machine learning models have greater predictive power and can offer useful tools to identify individuals with spinal metastatic disease who are experiencing severe psychological distress.

Rheumatic diseases are associated with a significant decline in quality of life, which is not only related to the progression of the underlying disease but also to the development of coexisting conditions. One of the possible complications in this group of diseases is ocular involvement. Impaired vision is strongly associated with a significant decline in quality of life and can also exacerbate problems related to physical functioning. Consequently, it can lead to serious complications in the treatment of the underlying disease. Additionally, from a clinical point of view, it is also important to note that ocular diseases may precede the occurrence of inflammatory joint and spinal diseases, as well as organ involvement in systemic connective tissue disorders. Therefore, paying attention to ocular symptoms can help in early diagnosis and thus improve patient prognosis. For the aforementioned reasons, ocular diseases should be carefully considered in routine rheumatologic practice. [ABSTRACT FROM AUTHOR]

Background and Objectives Globally, older adults are undergoing spine surgery for degenerative spine disease at exponential rates. However, little is known about their experiences of living with and having surgery for this debilitating condition. This study investigated older adults' understanding and experiences of living with and having surgery for degenerative spine disease. Research Design and Methods Qualitative methods, grounded theory, guided the study. Fourteen older adults (≥65 years) were recruited for in-depth interviews at 2 time-points: T1 during hospitalization and T2, 1–3-months postdischarge. A total of 28 interviews were conducted. Consistent with grounded theory, purposive, and theoretical sampling were used. Data analysis included open, axial, and selective coding. Results A conceptual model was developed illustrating the process older adults with degenerative spine disease experience, trying to get their life back. Three key categories were identified (1) Losing Me , (2) Fixing Me , and (3) Recovering Me. Losing Me was described as a prolonged process of losing functional independence and the ability to socialize. Fixing Me consisted of preparing for surgery and recovery. Recovering Me involved monitoring progression and reclaiming their personhood. Conditions, including setbacks and delays, slowed their trajectory. Throughout, participants continually adjusted expectations. Discussion and Implications The conceptual model, based on real patient experiences, details how older adults living with and having surgery for degenerative spine disease engage in recovering who they were prior to the onset of symptoms. Our findings provide a framework for understanding a complex, protracted trajectory that involves transitions from health to illness working toward health again. [ABSTRACT FROM AUTHOR]

Interspinous spacers are a minimally invasive surgical device for treating degenerative lumbar diseases, limiting spinal extension, and decreasing pressures within the disc and facets, relieving symptoms caused by lumbar spinal stenosis. This work uses the finite element method to calculate the stresses and deformations of an interspinous spacer with steel wire clamping. The cables also provide an easier way to set up the device. The reconstruction of the model was undertaken by computerized tomography, considering a person with average Mexican height (1.64 m) and a mass index grade of 2 (108 kg). The maximum movements reported in the literature were used for the range of motion. The interspinous spacer increases in a ratio of 2.7 times the stresses. Still, these stresses are generated in the prosthesis, which causes the vertebrae to be relieved since the forces and pressures are reduced. Deformations decrease by 53% with the reduction of the range of motion. Therefore, the prosthesis provides excellent stability for the vertebrae. [ABSTRACT FROM AUTHOR]

Background: Patients with spinal abnormalities often struggle with fecal and/or urinary incontinence (up to 87 and 92%, respectively) and require a collaborative approach to bowel management in conjunction. Methods: To define existing approaches and propose state-of-the-art bowel management, a literature search was performed using Medline/PubMed, Google Scholar, Cochrane, and EMBASE databases and focusing on the manuscripts published July 2013 and July 2023. Results: Patients with spinal anomalies have impaired innervation of the rectum and anal canal, decreasing the success rate from laxatives and rectal enemas. Thus, transanal irrigations and antegrade flushes are widely utilized in this group of patients. Based on spinal MRI, the potential for bowel control in these children depends on age, type, and lesion level. On referral for bowel management, a contrast study is performed to assess colonic motility and evacuation of stool, followed by a series of abdominal X-rays to define colonic emptying and adjust the regimen. The options for management include laxatives, rectal enemas, transanal irrigations, antegrade flushes, and the creation of a stoma. Approximately 22–71% of patients achieve social continence dependent on the type and level of the lesion. Conclusion: Patients with spinal anomalies require a thorough assessment for continence potential and stool burden prior to initiation of bowel management. The optimal treatment option is defined according to the patient's age, anatomy, and mobility. The likelihood of independent bowel regimen administration should be discussed with the patients and their caregivers. [ABSTRACT FROM AUTHOR]

Hard-to-heal or recurrent leg ulcers can have multiple aetiologies. One of these is incompetent veins. The main focus of this article is to discuss the common treatment for venous leg ulcers with the use of sclerotherapy. This simple surgical procedure obliterates smaller veins and telangiectasia. Veins with larger diameters (varicosities) can be treated with ablation therapy. The intent of sclerosis or ablation therapy is to destroy the incompetent veins and allow the collateral circulation to improve venous return, decreasing venous hypertension, which then enhances skin closure, wound healing and the resolution of the ulcer.

Study Design: Retrospective cohort study. Objectives: To compare outcomes of percutaneous pedicle screw fixation (PPSF) to open posterior stabilization (OPS) in spinal instability patients and minimal access separation surgery (MASS) to open posterior stabilization and decompression (OPSD) in metastatic spinal cord compression (MSCC) patients. Methods: We analysed patients who underwent surgery for thoracolumbar metastatic spine disease (MSD) from Jan 2011 to Oct 2017. Patients were divided into minimally invasive spine surgery (MISS) and open spine surgery (OSS) groups. Spinal instability patients were treated with PPSF/OPS with pedicle screws. MSCC patients were treated with MASS/OPSD. Outcomes measured included intraoperative blood loss, operative time, duration of hospital stay and ASIA-score improvement. Time to initiate radiotherapy and perioperative surgical/non-surgical complications was recorded. Propensity scoring adjustment analysis was utilised to address heterogenicity of histological tumour subtypes. Results: Of 200 eligible patients, 61 underwent MISS and 139 underwent OSS for MSD. There was no significant difference in baseline characteristics between MISS and OSS groups. In the MISS group, 28 (45.9%) patients were treated for spinal instability and 33 (54.1%) patients were treated for MSCC. In the OSS group, 15 (10.8%) patients were treated for spinal instability alone and 124 (89.2%) were treated for MSCC. Patients who underwent PPSF had significantly lower blood loss (95 mL vs 564 mL; P <.001) and surgical complication rates(P <.05) with shorter length of stay approaching significance (6 vs 19 days; P =.100) when compared to the OPS group. Patients who underwent MASS had significantly lower blood loss (602 mL vs 1008 mL) and shorter length of stay (10 vs 18 days; P =.098) vs the OPSD group. Conclusion: This study demonstrates the benefits of PPSF and MASS over OPS and OPSD for the treatment of MSD with spinal instability and MSCC, respectively. [ABSTRACT FROM AUTHOR]

Study Design: This study is a retrospective review. Objective: Central sensitization (CS) is a neurological phenomenon that involves hypersensitivity of the central nervous system. The central sensitization inventory (CSI) was developed as a screening tool to assess CS-related symptoms. The purpose of this study was to evaluate the association of preoperative CSI scores with patient-reported outcome measures (PROMs) including neurological symptoms for patients who underwent spine surgeries in a multicenter study. Methods: A consecutive 673 patients who underwent spine surgery at 8 different institutions were included in this study. Preoperative CSI scores were assessed for all subjects. The participants completed the following PROMs: the Oswestry Disability Index (ODI), the Japanese Orthopaedic Association (JOA) back pain evaluation questionnaire (JOABPEQ) for lumbar spinal diseases, and the JOA cervical myelopathy evaluation questionnaire (JOACMEQ) for cervical spinal diseases. The association of CSI scores with PROMs was statistically evaluated. Results: The average CSI score for the total subjects was 23.6 ± 13.5. The subjects with CS-related symptoms (CSI ≥ 40) were 13.2% (n = 89). The CSI score showed a significant and weak-to-moderate correlation with the PROMs including neurological symptoms that included all the domains of the JOACMEQ for cervical spinal diseases, and JOABPEQ and ODI for lumbar spinal diseases. Among these, psychological factors had the most influence on the correlation with CSI score. Conclusion: Central sensitization evaluated by the CSI is related to neurological symptoms and health-related quality of life in patients undergoing elective spine surgery. [ABSTRACT FROM AUTHOR]

While traditionally considered a disorder of the basal ganglia, brainstem, and cerebellum, multiple reports have shown that spinal cord pathologies may lead to dystonia. In this article, we first discuss various spinal movement disorders and the differences between tonic spasms, spinal dystonia, spinal myoclonus, spinal tremors, and paroxysmal dyskinesia. We review potential pathogenesis of spinal dystonia. We then focus on reports of dystonia secondary to spinal cord demyelinating diseases such as multiple sclerosis and neuromyelitis optica spectrum disorders. We conclude by discussing the potential treatment options for spinal dystonia. [ABSTRACT FROM AUTHOR]

Objective: Surgical management of elderly patients with spinal tuberculosis and severe osteoporosis is challenging. Cement-augmented pedicle screws (CAPS) have been specifically designed for elderly patients with osteoporotic spines. Herein, we investigated the feasibility of CAPS applied in elderly patients with spinal tuberculosis and severe osteoporosis. Methods: We retrospectively analyzed data of patients with spinal tuberculosis and severe osteoporosis between January 2017 and January 2021. Surgical data, including surgical duration and intraoperative blood loss, were recorded. Radiological parameters, such as correction of regional kyphotic angle and screw loosening, were also evaluated. Additionally, visual analog scores (VAS) and Oswestry disability index (ODI) were used to evaluate back pain and functional recovery, respectively. Erythrocyte sedimentation (ESR) and C-reactive protein (CRP) concentrations were detected to assess tuberculosis activity. The presence of complications and fusion rate was also assessed. Results: A total of 15 patients were included in this study. The surgical duration was 263.0 ± 56.2 min, with an average blood loss of 378.7 ± 237.0 ml. The correction of regional kyphotic angle was 12.4° ± 15.0°, and it was well maintained until the final follow-up. The mean VAS decreased from 6.0 ± 1.2 points to 0.5 ± 0.6 points, and ODI reduced from 37.8% ± 7.6% to 8.3% ± 2.8% (P < 0.01). At the final follow-up, ESR and CRP levels were within normal range. Bony fusion occurred in all patients, with an average fusion duration of 8.8 ± 1.5 months. No cases of pedicle screw pullout, screw loosening, or pseudoarthrosis occurred. Tuberculosis recurrence and dissemination were not observed during the follow-ups. Conclusions: CAPS fixation is an effective and safe technique to achieve solid fixation and favorable clinical outcomes in elderly patients with spinal tuberculosis and severe osteoporosis.

Background: Partial neuromuscular blockade (NMB) has been applied for some surgeries to reduce bleeding and prevent patient movement for spinal surgery. Sugammadex selectively binds to rocuronium in the plasma and consequently lowers the rocuronium concentration at the neuromuscular junction. In this study, we aimed to observe whether the success rate of transcranial motor-evoked potential (TceMEP) can be increased by sugammadex compared with partial NMB during spinal surgery. Methods: Patients who underwent elective spinal surgery with TceMEP monitoring were randomly assigned to the sugammadex group and control group. Rocuronium was continuously infused to maintain the train of four counts (TOFc) = 2. The sugammadex group discontinued rocuronium infusion at the time of TceMEP monitoring and was infused with 2 mg/kg sugammadex; the control group was infused with the same dose of saline. Results: A total of 171 patients were included. The success rate of TceMEP monitoring in the sugammadex group was significantly higher than that in the control group. TceMEP amplitudes were greater in the sugammadex group than in the control group at 5 min, 10 min, and 20 min after the start of motor-evoked potential monitoring. The latencies of upper extremity TceMEPs monitoring showed no difference between groups. TOF ratios were greater in the sugammadex group at 5 min, 10 min, and 20 min after the start of motor-evoked potential monitoring. There were no adverse effects caused by sugammadex. Conclusions: Sugammadex can improve the success rate of motor-evoked potential monitoring compared with moderate neuromuscular blockade induced by continuous infusion of rocuronium in spinal surgery. Trial registration: The study was registered on clinicaltrials.gov.cn on 29/10/2020 (trial registration number: NCT04608682). [ABSTRACT FROM AUTHOR]

Objective: To determine the safety and efficacy of percutaneous endoscopic lumbar discectomy (PELD) combined with platelet-rich plasma (PRP) hydrogel injection in patients with lumbar disc herniation (LDH). Methods: A total of 98 consecutive patients with LDH who underwent either PELD combined with PRP hydrogel injection or PELD alone were reviewed. This retrospective study was performed between January 2019 and January 2021. Clinical outcomes were compared in the visual analog scale (VAS) for low back pain and leg pain, Oswestry disability index (ODI), Japanese Orthopaedic Association (JOA) scores, and Macnab criteria. Intervertebral disc height on MRI was measured, and the Pfirrmann grade classification was used pre-operatively and post-operatively. Results: No severe adverse events were reported during an 18-month follow-up period. VAS scores for back pain were decreased at 1 month, 3 months, and 18 months in the treatment group than that in the control group. JOA score and ODI in the treatment group at 3-month and 18-month follow-up was lower than that in the control group (P < 0.05). The excellent and good rate of the Macnab criteria was 92.0% (46/50) in the treatment group and 89.6% (43/48) in the control group (P > 0.05). The comparison of Pfirrmann grading and disc height at 18-month follow-up showed significant difference in two groups (P < 0.05). The recurrence of LDH in the treatment group was lower than that in the control group (P < 0.05). Conclusions: We suggest that PELD combined with PRP hydrogel injection to treat patients with LDH is a safe and promising method. PRP injection was beneficial for disc remodelling after PELD.

LUMBAR pain , *SPINE diseases , *MAGNETIC resonance imaging , *MEDICAL protocols , *LUMBAR vertebrae , *COMPUTER-assisted image analysis (Medicine) - Abstract
Management of patients suffering from low back pain (LBP) is challenging and requires development of diagnostic techniques to identify specific patient subgroups and phenotypes in order to customize treatment and predict clinical outcome. The Back Pain Consortium (BACPAC) Research Program Spine Imaging Working Group has developed standard operating procedures (SOPs) for spinal imaging protocols to be used in all BACPAC studies. These SOPs include procedures to conduct spinal imaging assessments with guidelines for standardizing the collection, reading/grading (using structured reporting with semi-quantitative evaluation using ordinal rating scales), and storage of images. This article presents the approach to image acquisition and evaluation recommended by the BACPAC Spine Imaging Working Group. While the approach is specific to BACPAC studies, it is general enough to be applied at other centers performing magnetic resonance imaging (MRI) acquisitions in patients with LBP. The herein presented SOPs are meant to improve understanding of pain mechanisms and facilitate patient phenotyping by codifying MRI-based methods that provide standardized, non-invasive assessments of spinal pathologies. Finally, these recommended procedures may facilitate the integration of better harmonized MRI data of the lumbar spine across studies and sites within and outside of BACPAC studies.

Rosai-Dorfman disease (RDD) is a condition of unknown etiology, and characterized by the proliferation of histiocytes. RDD most commonly affects lymph nodes, and central nervous system (CNS) involvement is rare. Here, we describe the case of a 43-year-old man who presented with an intradural tumour of the thoracic spine. The patient underwent a laminectomy for tumour resection and pathology results diagnosed the tumour as a RDD. Two years later, brain magnetic resonance imaging (MRI) revealed multiple intracranial dural-based lesions. Prednisolone treatment was initiated and led to resolution of the disease. We reviewed the literature to the investigate clinical characteristics, imaging features, diagnosis and treatment protocols pertaining to such cases. [ABSTRACT FROM AUTHOR]

Physiotherapists (PTs) have an essential role in the facilitation of patients' mobilization after lumbar spinal fusion (LSF). The aim of this study is to investigate whether PTs can predict one-year post-surgery outcome based on their first meeting with the patient immediately after LSF. A prospective cohort study with one-year follow-up was conducted. In the first days after surgery, the PTs from hospital wards were asked to predict the patients' overall LSF outcome one year after surgery. One year after surgery, the patients received a questionnaire including the Oswestry Disability Index (ODI), visual analogue scales (VAS) for leg and back pain, quality of life survey (EQ-5D-3 L), global perceived effect (GPA), and satisfaction with surgery outcome (SSO). Univariate and logistic regression were used to calculate the associations between the prognosis and predictive values. The study included 170 patients. The analyses showed a significant association between the PTs' prognosis and the primary outcome ODI (p <.01), VAS leg and back, EQ-5D-3 L, and GPE one-year post-surgery (p ≤.04). However, the predictive value of the PTs' prognosis was low (R2 ≤ 0.09). There was no significant association between the PTs' prognosis and the patients' SSO (p =.17; R2 = 0.01). There were significant associations between the PTs' prognosis and disability, pain, health-related quality of life and global perceived effect one-year post-surgery, although the associations had low predictive values. There was no significant association between the PTs' prognosis and patients' SSO after one year. The PTs' prognosis should not be used as a single component in further rehabilitation planning.

Spinal cord tumors are infrequently identified spinal diseases that are often difficult to diagnose even with magnetic resonance imaging (MRI) findings. To minimize the probability of overlooking these tumors and improve diagnostic accuracy, an automatic diagnostic system is needed. We aimed to develop an automated system for detecting and diagnosing spinal schwannomas and meningiomas based on deep learning using You Only Look Once (YOLO) version 4 and MRI. In this retrospective diagnostic accuracy study, the data of 50 patients with spinal schwannomas, 45 patients with meningiomas, and 100 control cases were reviewed, respectively. Sagittal T1-weighted (T1W) and T2-weighted (T2W) images were used for object detection, classification, training, and validation. The object detection and diagnosis system was developed using YOLO version 4. The accuracies of the proposed object detections based on T1W, T2W, and T1W + T2W images were 84.8%, 90.3%, and 93.8%, respectively. The accuracies of the object detection for two spine surgeons were 88.9% and 90.1%, respectively. The accuracies of the proposed diagnoses based on T1W, T2W, and T1W + T2W images were 76.4%, 83.3%, and 84.1%, respectively. The accuracies of the diagnosis for two spine surgeons were 77.4% and 76.1%, respectively. We demonstrated an accurate, automated detection and diagnosis of spinal schwannomas and meningiomas using the developed deep learning-based method based on MRI. This system could be valuable in supporting radiological diagnosis of spinal schwannomas and meningioma, with a potential of reducing the radiologist's overall workload. [ABSTRACT FROM AUTHOR]

Ankylosing spondylitis (AS) is a chronic, progressive inflammatory rheumatic disease affecting the spine, axial skeleton, and sacroiliac joints. Pathogenesis of AS encompasses enthesitis, synovitis, and osteoproliferation, leading to the formation of syndesmophytes, ankylosis, and spinal rigidity. Bioinformatics, an interdisciplinary field combining computer science, mathematics, and biology, enables the analysis of complex biological data for investigating AS pathogenesis. This review summarizes differentially expressed protein‐coding genes in peripheral blood or local tissues of AS patients compared with healthy controls and comprehensively reviews currently available therapeutic agents. The objective is to enhance the understanding of AS pathogenesis, inform diagnosis, identify novel therapeutic targets, and facilitate personalized medicine. This review contributes to a deeper understanding of AS pathogenesis and provides a foundation for developing innovative therapeutic approaches. [ABSTRACT FROM AUTHOR]

To establish a 'trustworthy' living systematic review (SR) with a meta-analysis of manual therapy for treating non-radicular cervical impairments. SR with meta-analysis Articles published between January 2010 and September 2022 were included from: Cochrane Central Register of Controlled Trials (CENTRAL); CINAHL; MEDLINE; PubMed; PEDro, and ProQuest Nursing and Allied Health. This SR included English-language randomized clinical trials (RCTs) of manual therapy involving adults used to treat non-radicular cervical impairments. The primary outcomes were pain and region-specific outcome measures. Cervicogenic headaches and whiplash were excluded to improve homogeneity. Two reviewers independently assessed RCTs. The prospective plan was to synthesize results with high confidence in estimated effects using GRADE. Thirty-five RCTs were screened for registration status. Twenty-eight were not registered or registered prospectively. In 5 studies, the discussion and conclusion did not match the registry, or this could not be determined. One study did not meet the external validity criterion, and another was rated as having a high risk of bias. One study met the inclusion and exclusion criteria, so practice recommendations could not be made. The remaining study did not identify any clinically meaningful group differences. Only one prospectively registered RCT met this SR's strict, high-quality standards. The single identified paper provides initial high-quality evidence on this topic. This SR establishes a foundation of trustworthiness and can be used to generate research agendas to determine the potential clinical utility of manual therapy directed at the cervical spine for non-radicular cervical complaints.

Background: Methicillin-susceptible Staphylococcus aureus (MSSA) occurs more frequently in the neonatal intensive care unit (NICU) than methicillin-resistant S. aureus (MRSA) and can result in comparable morbidity and mortality in the neonatal population. MSSA infection may present as pustulosis or cellulitis and evolve into bacteremia, pneumonia, endocarditis, brain abscesses, and osteomyelitis. There is a paucity of literature regarding the treatment and long-term outcomes in the premature infant. Clinical Findings: A 32-week twin developed MSSA sepsis with presentation of pain, decreased movement of upper extremities, and global hypotonia. Blood cultures remained positive despite antibiotic coverage. Primary Diagnosis: The infant was admitted to the level IV NICU with the diagnosis of MSSA bacteremia, with concern for dissemination and osteomyelitis. Interventions: Diagnostic studies included laboratory testing for sepsis evaluation, radiologic studies to evaluate for dissemination, immunologic testing to rule out complement deficiency, and hematology testing to rule out hypercoagulable conditions. Outcomes: Diagnostic testing showed extensive cellulitis, osteomyelitis, multiple liver abscesses, and epidural abscesses suggestive of spinal epidural abscess (SEA). Abscess debridement and irrigation on the left distal femur, left elbow, and right tibia were performed. The infant completed 8 weeks of IV antibiotic therapy. Immunologic and hematology testing was within normal limits. Practice Recommendations: Prompt recognition and follow-up for clinical signs of sepsis are vital when caring for premature infants. Inclusion of pediatric subspecialist recommendations to assure all diagnostic studies and treatments are completed can significantly impact the patient's outcome. Long-term follow-up is needed for premature infants with the diagnosis of SEA. [ABSTRACT FROM AUTHOR]

Purpose: Prospective evaluation of radiographic fusion outcomes in patients receiving instrumented posterior arthrodesis of the lumbar spine using a minimally invasive interspinous fixation device.Patients and Methods: All patients (n = 110) from a single US physician's practice who received instrumented posterior arthrodesis of the lumbar spine with a minimally invasive interspinous fixation device in the calendar year 2020 were invited to return for a follow-up CT scan to radiographically assess fusion. Forty-three patients, representing 69 total treated levels, consented to participate and received a lumbar CT scan at a mean of 459 days post-surgery (177 to 652). The interspinous/interlaminar fusion was assessed by 3 independent radiologists using a novel grading scale. Spinous process fractures were also assessed.Results: 92.8% of the assessed levels were considered fused. There were no intraoperative spinous process fractures. There were 4 spinous process fractures (5.8%) identified on CT imaging, all of which were asymptomatic and healed without subsequent intervention. There were no instances of device mechanical failure or device-related reoperation.Conclusion: Instrumented posterior arthrodesis of the lumbar spine using a minimally invasive interspinous fixation device provides clinically meaningful fusion rates with no reoperations and a low risk of spinous process fracture or other device-related complications.

Radiographic examination is essential for diagnosing spinal disorders, and the measurement of spino-pelvic parameters provides important information for the diagnosis and treatment planning of spinal sagittal deformities. While manual measurement methods are the golden standard for measuring parameters, they can be time consuming, inefficient, and rater dependent. Previous studies that have used automatic measurement methods to alleviate the downsides of manual measurements showed low accuracy or could not be applied to general films. We propose a pipeline for automated measurement of spinal parameters by combining a Mask R-CNN model for spine segmentation with computer vision algorithms. This pipeline can be incorporated into clinical workflows to provide clinical utility in diagnosis and treatment planning. A total of 1807 lateral radiographs were used for the training (n = 1607) and validation (n = 200) of the spine segmentation model. An additional 200 radiographs, which were also used for validation, were examined by three surgeons to evaluate the performance of the pipeline. Parameters automatically measured by the algorithm in the test set were statistically compared to parameters measured manually by the three surgeons. The Mask R-CNN model achieved an average precision at 50% intersection over union (AP50) of 96.2% and a Dice score of 92.6% for the spine segmentation task in the test set. The mean absolute error values of the spino-pelvic parameters measurement results were within the range of 0.4° (pelvic tilt) to 3.0° (lumbar lordosis, pelvic incidence), and the standard error of estimate was within the range of 0.5° (pelvic tilt) to 4.0° (pelvic incidence). The intraclass correlation coefficient values ranged from 0.86 (sacral slope) to 0.99 (pelvic tilt, sagittal vertical axis). [ABSTRACT FROM AUTHOR]

Objectives: We reported thirteen cases of percutaneous transforaminal endoscopic surgery (PTES) under local anesthesia and mini-incision L5/S1 OLIF (OLIF51) with a self-lock cage for the treatment of L5 spondylolisthesis. Methods: From Jan 2019 to Feb 2020, the patients with L5 spondylolisthesis with nerve root symptoms undergoing PTES and OLIF51 were included in this study. PTES under local anesthesia was performed in a prone position, and OLIF51 with a self-lock cage and allograft was then undertaken through a left abdominal mini-incision and oblique retroperitoneal approach between bilateral iliac vessels with the external oblique, internal oblique and transverse abdominal muscles bluntly separated in turn for L5/S1 in a right oblique position under general anesthesia. Back and leg pain were preoperatively and postoperatively evaluated using the VAS, and the clinical outcomes were evaluated with the ODI before surgery and at the 2-year follow-up. The anterior and posterior intervertebral space height (AISH, PISH), lumbar lordotic, and surgical segmental lordotic angle (SLA) were measured on lumbar spine X-rays preoperatively and postoperatively. The fusion status was assessed according to Bridwell's fusion grades. Results: Thirteen cases of L5 spondylolisthesis were included. The operation duration was 49.1 ± 5.6 min for PTES and 73.6 ± 8.2 min for OLIF. There was blood loss of 25 (15–45) ml. The incision length was 7.5 ± 1.1 mm for PTES and 46.8 ± 3.8 mm for OLIF. The hospital stay was 5 (4–6) days, and the follow-up duration was 29 (24–37) months. For the clinical evaluation, the VAS of back and leg pain significantly dropped after surgery (p < 0.001), and the ODI significantly decreased from 64.7 ± 7.8% to 12.9 ± 4.3% 2 years after surgery (p < 0.001). AISH, PISH and SLA significantly improved after surgery (p < 0.05). Fusion grades based on the Bridwell grading system at the 2-year follow-up were grade I in 9 segments (69.2%) and grade II in 4 segments (30.8%). No patients had any form of permanent iatrogenic nerve damage or major complications. No failure of instruments was observed. Conclusions: PTES and mini-incision OLIF51 with a self-lock cage is a viable option of minimally invasive surgery for L5 spondylolisthesis, which can achieve direct neurologic decompression, satisfactory fusion and hardly destroys the rectus abdominis and its sheath, paraspinal muscles and bone structures.

Over the last decade, our understanding of spliceosome structure and function has significantly improved, refining the study of the impact of dysregulated splicing on human disease. As a result, targeted splicing therapeutics have been developed, treating various diseases including spinal muscular atrophy and Duchenne muscular dystrophy. These advancements are very promising and emphasize the critical role of proper splicing in maintaining human health. Herein, we provide an overview of the current information on the composition and assembly of early splicing complexes—commitment complex and pre-spliceosome—and their association with human disease.

Background Staphylococcus aureus is a global pathogen that is frequently responsible for healthcare-associated infections, including surgical site infections (SSIs). Current infection prevention and control approaches may be limited, with S. aureus antibiotic resistance remaining problematic. Thus, a vaccine to prevent or reduce S. aureus infection is critically needed. We evaluated the efficacy and safety of an investigational 4-antigen S. aureus vaccine (SA4Ag) in adults undergoing elective open posterior spinal fusion procedures with multilevel instrumentation. Methods In this multicenter, site-level, randomized, double-blind trial, patients aged 18–85 years received a single dose of SA4Ag or placebo 10–60 days before surgery. SA4Ag efficacy in preventing postoperative S. aureus bloodstream infection and/or deep incisional or organ/space SSIs was the primary end point. Safety evaluations included local reactions, systemic events, and adverse events (AEs). Immunogenicity and colonization were assessed. Results Study enrollment was halted when a prespecified interim efficacy analysis met predefined futility criteria. SA4Ag showed no efficacy (0.0%) in preventing postoperative S. aureus infection (14 cases in each group through postoperative day 90), despite inducing robust functional immune responses to each antigen compared with placebo. Colonization rates across groups were similar through postoperative day 180. Local reactions and systemic events were mostly mild or moderate in severity, with AEs reported at similar frequencies across groups. Conclusions In patients undergoing elective spinal fusion surgical procedures, SA4Ag was safe and well tolerated but, despite eliciting substantial antibody responses that blocked key S. aureus virulence mechanisms, was not efficacious in preventing S. aureus infection.

Backgrounds: Anterior lumbar interbody fusion (ALIF) is an attractive option for revision lumbar interbody fusion as it provides wide access for implant removal and accommodation of large interbody grafts for fusion. However, revision lumbar interbody fusion surgery has not been found to result in significantly better functional outcomes compared with other approaches. To date, no prognostic factors of anterior lumbar interbody fusion in revision lumbar interbody fusion have been reported. In this study, we investigated the surgical results and possible prognostic factors of anterior lumbar interbody fusion in revision lumbar interbody fusion. Methods: Patients who received revision interbody fusion surgery between January 2010 and May 2018 in our hospital were reviewed. Clinical outcomes were determined according to whether the VAS score improvement in back pain and leg pain reached the minimum clinically important difference (MCID) and Macnab criteria. Radiographic outcomes were assessed with fusion rate, preoperative, and postoperative lumbar lordosis. Operative-relative factors that may affect clinical outcomes, such as BMI, existence of cage migration, cage subsidence, pseudarthrosis, previous procedure, and number of fusion segments, were collected and analyzed. Results: A total of 22 consecutive patients who received ALIF for revision interbody fusion surgery were included and analyzed. There were 9 men and 13 women with a mean age at operation of 56 years (26–78). The mean follow-up was 73 months (20–121). The minimal clinically important difference (MCID) was reached in 11 (50%) of the patients for back pain and 14 (64%) for leg pain. According to the modified Macnab criteria, 73% of the patients in this study had successful outcomes (excellent or good). The pain and lumbar lordosis had significant improvement (P < 0.05). Preoperative fusion segment ≥ 2 was shown to be a poor prognostic factor for back pain improvement reaching MCID (P = 0.043). Conclusions: ALIF has proven effective for revision lumbar fusion surgery, yielding positive clinical and radiographic results. However, having two or more preoperative fusion segments can negatively impact back pain improvement. Level of evidence: IV. [ABSTRACT FROM AUTHOR]

Purpose: To construct an injectable, sustained-release fibrin gel containing rhein to solve the problem of low bioavailability of rhein, and observe its efficacy in the treatment of intervertebral disc degeneration. Methods: The fibrin gel containing rhein was first synthesized in advance. Subsequently, the materials were characterized by various experimental methods. Secondly, the degenerative cell model was constructed by stimulating nucleus pulposus cells with lipopolysaccharide (LPS), and the corresponding intervention treatment was carried out to observe the effect in vitro. Finally, the rat tail intervertebral disc was acupunctured by needles to establish the intervertebral disc degeneration model, and the effect of the material was observed through intradiscal injection. Results: The fibrin glue containing rhein (rhein@FG) showed good injectability, sustained release and biocompatibility. Rhein@FG can improve the LPS-induced inflammatory microenvironment, regulate ECM metabolic disorders of nucleus pulposus cells and aggregation of the NLRP3 inflammasome in vitro, and inhibit cell pyroptosis. Furthermore, in vivo experiments, rhein@FG effectively prevented needle puncture-induced intervertebral disc degeneration in rats. Conclusions: Rhein@FG has better efficacy than rhein or FG alone due to its slow release and mechanical properties, which can be used as a potential replacement therapy for intervertebral disc degeneration.

Introduction: Local wound infiltration is an effective, simple, and practical method of postoperative analgesia. Time and resource consumption is minor; while being more acceptable. A low incidence of complications; and no major contraindications have been noted, other than patient refusal or local infection. Various systematic reviews outline the benefits of adjuvants such as opioids, non-steroidal anti-inflammatory drugs, steroids, alpha-2 agonists, ketamine, etc. in increasing the analgesic efficacy and opioidsparing effect when combined with local anaesthetic agents via wound infiltration; while also providing supportive evidence of the safety of these agents. Material and Method: The study was as a prospective double blind randomised controlled trial conducted between April 2022 to April 2023. The inclusion criteria were age 30 to 60 years, lumbar degenerative disc diseases needing posterior spinal fixation of one-or two-disc levels and of American Society of Anaesthesiologists (ASA) grade I/II. The criteria for exclusion were surgery of >2-disc levels (>3 vertebrae), surgery for non-degenerative spinal diseases, previous spinal surgery, osteoporosis and spondylolisthesis of grade III/IV, altered hepatic or renal parameters or ASA grade III/IV. Surgical decision was made according to the patient's history, flexion extension radiographs and MRI, with consultations with the patient. Patients were then randomly allocated randomly in 2 groups by a computer-generated randomization. Group N received inj nalbuphine 10mg, 0.5 % inj bupivacaine 9ml and 10ml normal saline while group B received inj butorphanol 1mg, inj bupivacaine 9ml and normal saline 10 ml. Results: At end of the recovery, patients in nalbuphine group had mild pain with mean NRS score 2.5±0.5. The pain remained mild in nature till 4 hours and then starts increasing slowly with NRS at 6 hours 3.8±0.7 and peaking between 6 and hours (table 2, figure 1). The hearts rate and MAP were also had similar trends with progressive increase from 4 hours and peaks at 8 hours. In the butorphanol group the mean NRS score at the end of recovery was 2.8±0.6 which was comparable to the that of nalbuphine group. It started to increase before 4 hours, with mean NRS score at 4 hours 3.8±0.7 and peaked between 4 and 6 hours. During intergroup comparison mean heart rates, MAP and NRS were comparable between the two groups at baseline, 0 hour and 2 hours. Significant difference in NRS score were observed among the two groups at 4 hours (p - 0.03), 6 hours (p-0.01) and 8 hours (p-0.006). After 8 hours the heart rate, MAP and NRS in both groups were comparable (p>0.05). Conclusion: In this study we have compared the benefits and safety of two different opioids as adjuvants to local infiltration in spine surgery. The study was done in similar group of patients of degenerative lumbar disease operated with similar surgery (lumbar spinal fixation and decompression) by a single surgeon. The results demonstrated that the NRS score remains low at both groups till 4 hours of recovery and the patients were haemodynamically stable with no tachycardia or increased blood pressure. In the butorphanol group the NRS score increase around 4 hours of recovery and the request for first rescue analgesia was between 4 and 6 hours, mean 289.7±46.8 minutes. But in nalbuphine group, NRS score remained low up to 8 hours and mean time for request of first rescue analgesia was 492.4±56.3 minutes. [ABSTRACT FROM AUTHOR]

Purpose: Compare the outcomes of randomized clinical trials of cervical disc arthroplasty (CDA) versus anterior cervical discectomy with fusion (ACDF), with a minimum follow-up of 7 years. Methods: Nine randomized clinical trials were selected. The clinical, radiological, and surgical outcomes were analyzed, including functional and pain scores, range of motion, adjacent segment degeneration, adverse events, and need for reoperation. Results: 2664 patients were included in the study. Pooled results indicated that the CDA group had a significantly higher overall success rate (p < 0.001), a higher improvement in the neck disability index (NDI) (p = 0.002), less VAS arm pain (p = 0.01), and better health questionnaire SF-36 physical component (p = 0.01) than ACDF group. Likewise, the pooled results indicated a significantly higher motion rate (p < 0.001), less adjacent syndrome (p < 0.05), and a lower percentage of reoperation (p < 0.001) in the CDA group. There were no significant differences between the CDA and ACDF groups in the neck pain scale (p = 0.11), the health questionnaire SF-36 mental component (p = 0.10), and in adverse events (p = 0.42). Conclusion: In long-term follow-up, CDA showed a better overall success rate, better improvement in NDI, less VAS arm pain, better health questionnaire SF-36 physical component, a higher motion rate, less adjacent syndrome, and less reoperation rate than ACDF. No significant differences were found in the neck pain scale, SF-36 mental component, and in adverse events. [ABSTRACT FROM AUTHOR]

Purpose: Evidence on spontaneous sacroiliac joint (SIJ) ankylosis is lacking. The aim of this analysis was to assess the prevalence of spontaneous SIJ ankylosis and examined different ankylosis patterns and risk factors for spontaneous SIJ ankylosis. Methods: Pelvic computed tomography (CT) data of 102 consecutive patients with spinal pathologies were compared to CT of a control group consisting of 102 consecutive patients without spinal pathologies. SIJ ankylosis patterns and risk factors for SIJ ankylosis, such as age, sex, and previous spinal fusion surgery were examined. Results: Overall, 117 men and 86 women were examined between 2019 and 2020. Non-spinal patients were significantly older (mean age 70.5 years, standard deviation [SD] 11.4) than those in the spinal group (mean age 65.3 years, SD 14.3; p = 0.005). The prevalence of SIJ ankylosis was 24.5% in the non-spinal group and 23.5% in the spinal group. The anterior ankylosis type prevalence was 91.7% in the spinal group, compared to 48.0% in the non-spinal group. Factors associated with SIJ ankylosis were older age (odds ratio [OR] 1.04, 95% confidence interval [CI] 1.01–1.07, p = 0.004) and male sex (OR 5.14, 95% CI 2.29–11.55, p < 0.001). Conclusion: Spontaneous ankylosis of the SIJ was a frequent phenomenon in patients with and without spinal pathologies and more likely with older age and male sex. Anterior type SIJ ankylosis was substantially more frequent in patients with spinal pathologies. This may be due to strain exerted on the anterior SIJ aspects in patients with compromised posture due to spine degeneration. [ABSTRACT FROM AUTHOR]

Anterior cervical discectomy and fusion (ACDF) is a commonly performed procedure for degenerative cervical spine disease. Rare complications of ACDF surgery include hardware failure, in the form of screw loosening and migration, or rod breakage. We present a case in which we removed a migrated screw lodged in the esophagus from a patient with a failed anterior cervical fusion. To present a surgical technique and considerations to remove a migrated screw. The previous ACDF incision was reopened and exposure was gained under the guidance of a head and neck surgeon. Longus coli were mobilized off the spine bilaterally with electrocautery. After dissection, the screw was found lodged in the longitudinal muscle of the esophageal wall and excised with the use of a 15-blade. The integrity of the esophageal mucosa and submucosa was maintained and subsequently checked with rigid esophagoscopy. Fluoroscopy was used to confirm that all hardware was removed, with the exception of the anterior cages. The dislodged screw, which was embedded in the esophagus, was successfully removed. Failure of an ACDF carries a risk of screw migration, which may be asymptomatic even if the screw is lodged in the esophagus. Additional considerations are required with potential violations of the adjacent viscera. [ABSTRACT FROM AUTHOR]

This study aimed to investigate the relationship between depression and outcome of percutaneous endoscopic lumbar discectomy (PELD) in patients with lumbar disc herniation. We examined 268 patients who underwent PELD for lumbar disc herniation and were followed for five years. Patients were grouped according to mood: normal mood (159 patients) and continuous depression (109 patients). Depressive symptoms were assessed using the 21-item Beck Depression Inventory. Back and leg pain were assessed using the visual analogue scale. Subjective disability was measured using the Oswestry Disability Index. Neurological function and physical disability were assessed using the Japanese Orthopaedic Association score. Disc-height ratio and intervertebral instability were measured to assess lumbar stability. Clinical and radiological data were recorded before surgery and at the 3-month, 6-month, 1-year, 2-year, and 5-year follow-ups. Although the Japanese Orthopaedic Association, visual analogue scale, and Oswestry Disability Index scores did not significantly differ between groups before surgery, all three scores significantly differed between groups at all follow-up time points after PELD (p < 0.05). Measurements of disc-height ratio and intervertebral instability did not significantly differ between the groups before surgery nor at any point after surgery (P > 0.05). Patients with continuous depression exhibited less improvement in symptom severity and disability score after PELD at all time points in the five years after surgery. Depression had little effect on lumbar vertebral stability after PELD. Interventions to detect and treat depression should be performed before and after surgery. [ABSTRACT FROM AUTHOR]

CFR-PEEK is gaining popularity in spinal oncological applications due to its reduction of imaging artifacts and radiation scattering compared with titanium, which allows for better oncological follow-up and efficacy of radiotherapy. We evaluated the use of these materials for the treatment of lumbar degenerative diseases (DDs) and considered the biomechanical potential of the carbon fiber in relation to its modulus of elasticity being similar to that of bone. Twenty-eight patients with DDs were treated using CRF-PEEK instrumentation. The clinical and radiographic outcomes were collected at a 12-month FU. Spinal fusion was evaluated in the CT scans using Brantigan scores, while the clinical outcomes were evaluated using VAS, SF-12, and EQ-5D scores. Out of the patients evaluated at the 12-month FU, 89% showed complete or almost certain fusion (Brantigan score D and E) and presented a significant improvement in all clinical parameters; the patients also presented VAS scores ranging from 6.81 ± 2.01 to 0.85 ± 1.32, EQ-5D scores ranging from 53.4 ± 19.3 to 85.0 ± 13.7, SF-12 physical component scores (PCSs) ranging from 29.35 ± 7.04 to 51.36 ± 9.75, and SF-12 mental component scores (MCSs) ranging from 39.89 ± 11.70 to 53.24 ± 9.24. No mechanical complications related to the implant were detected, and the patients reported a better tolerance of the instrumentation compared with titanium. No other series of patients affected by DD that was stabilized using carbon fiber implants have been reported in the literature. The results of this pilot study indicate the efficacy and safety of these implants and support their use also for spinal degenerative diseases. [ABSTRACT FROM AUTHOR]

Introduction: The differential diagnoses of lumbar spinal stenosis (LSS) and adult spinal deformity (ASD) have been demonstrated primarily using sagittal radiographic spinopelvic parameters. However, it is more important to know the differences in the characteristic clinical symptoms to make accurate treatment decisions. Recently, the relationship between spinal disease and Locomotive Syndrome (LS) has been reported. Additionally, the Geriatric Locomotive Function Scale-25 (GLFS-25) was reported to be a useful scale to evaluate disease severity and characteristic clinical symptoms in spinal disease. Methods: Sixty-nine consecutive patients with ASD and 196 patients with LSS who underwent spinal surgery were included. Locomotive dysfunction was evaluated using the GLFS-25 questionnaire and physical performance tests including the two-step test and the stand-up test, measured preoperatively. The correlations between sagittal spinopelvic parameters of ASD and LS were examined. Results: All subjects with lumbar degenerative disease in the present study were diagnosed with LS preoperatively. The severity of LS in patients with LSS and ASD were statistically similar. GLFS-25 scores in the mobility and community domain were similarly poor in both groups. Several scores in the domestic life and self-care domains were significantly worse in the ASD group. Question 20 of the GLFS-25, related to load-bearing tasks and housework, was significantly associated with a large pelvic incidence in ASD patients. Conclusions: Lumbar degenerative disease requiring surgery severely affects the LS of older people. ASD patients had more difficulty with load-bearing tasks and housework such as cleaning the yard, carrying heavy bedding, dressing, and bathing compared to LSS patients. [ABSTRACT FROM AUTHOR]

Artificial intelligence (AI) and machine learning (ML) are rapidly becoming integral components of modern healthcare, offering new avenues for diagnosis, treatment, and outcome prediction. This review explores their current applications and potential future in the field of spinal care. From enhancing imaging techniques to predicting patient outcomes, AI and ML are revolutionizing the way we approach spinal diseases. AI and ML have significantly improved spinal imaging by augmenting detection and classification capabilities, thereby boosting diagnostic accuracy. Predictive models have also been developed to guide treatment plans and foresee patient outcomes, driving a shift towards more personalized care. Looking towards the future, we envision AI and ML further ingraining themselves in spinal care with the development of algorithms capable of deciphering complex spinal pathologies to aid decision making. Despite the promise these technologies hold, their integration into clinical practice is not without challenges. Data quality, integration hurdles, data security, and ethical considerations are some of the key areas that need to be addressed for their successful and responsible implementation. In conclusion, AI and ML represent potent tools for transforming spinal care. Thoughtful and balanced integration of these technologies, guided by ethical considerations, can lead to significant advancements, ushering in an era of more personalized, effective, and efficient healthcare.

BACKGROUND: The incidence rate of degenerative spinal deformity (DSD) has gradually increased in the elderly. Currently, the relationship between the functional status of trunk muscle and the spinal-pelvic parameters of DSD patients remains unclear. OBJECTIVE: This paper aims to explore the relationship between the two factors and provide new clues for exploring the mechanism of the occurrence and development of DSD. METHODS: A total of 41 DSD patients treated in our hospital (DSD group) and 35 healthy volunteers (control group) were selected. Muscle strength was evaluated using an IsoMed-2000 isokinetic dynamometer, and the trunk flexor and extensor peak torque (PT) of subjects was measured at a low, medium, and high angular velocity of 30 ∘ /s, 60 ∘ /s, and 120 ∘ /s, respectively. Hand grip strength (HGS) was assessed using an electronic grip dynamometer and Surgimap software was used to measure the spinal-pelvic parameters, including the sagittal vertical axis (SVA), thoracic kyphosis (TK), lumbar lordosis (LL), sacral slope (SS), pelvic tilt (PT), pelvic incidence rate (PI), and PI-LL, and the relationship between trunk muscle function and various parameters was analyzed. RESULTS: Under the three angular velocities, the flexor and extensor PT values in the DSD group were lower than those in the control group, and only the extensor PT showed a statistically significant difference (P < 0.05). There was no significant difference in HGS between the two groups (P > 0.05). In the DSD group, the extensor PT at 30 ∘ /s was significantly negatively correlated with SVA (P < 0.05). At 60 ∘ /s and 120 ∘ /s, the extensor PT was significantly negatively correlated with SVA and PT (P < 0.05). CONCLUSION: Trunk extensor strength is significantly lower in DSD patients than in normal controls. The decline in trunk extensor strength in DSD patients is a type of local muscle dysfunction more closely related to the deformity, which is likely involved in the compensatory mechanism of DSD and may reflect the overall imbalance of the trunk.

Purpose: Scoring systems for metastatic spine disease focus on predicting long- to medium-term mortality or a combination of perioperative morbidity and mortality. However, accurate prediction of perioperative mortality alone may be the most important factor when considering surgical intervention. We aimed to develop and evaluate a new tool, the H2-FAILS score, to predict 30-day mortality after surgery for metastatic spine disease. Methods: Using the National Surgical Quality Improvement Program database, we identified 1195 adults who underwent surgery for metastatic spine disease from 2010 to 2018. Incidence of 30-day mortality was 8.7% (n = 104). Independent predictors of 30-day mortality were used to derive the H2-FAILS score. H2-FAILS is an acronym for: Heart failure (2 points), Functional dependence, Albumin deficiency, International normalized ratio elevation, Leukocytosis, and Smoking (1 point each). Discrimination was assessed using area under the receiver operating characteristic curve (AUC). The H2-FAILS score was compared with the American Society of Anesthesiologists Physical Status Classification (ASA Class), the 5-item modified Frailty Index (mFI-5), and the New England Spinal Metastasis Score (NESMS). Internal validation was performed using bootstrapping. Alpha = 0.05. Results: Predicted 30-day mortality was 1.8% for an H2-FAILS score of 0 and 78% for a score of 6. AUC of the H2-FAILS was 0.77 (95% confidence interval: 0.72–0.81), which was higher than the mFI-5 (AUC 0.58, p < 0.001), ASA Class (AUC 0.63, p < 0.001), and NESMS (AUC 0.70, p = 0.004). Internal validation showed an optimism-corrected AUC of 0.76. Conclusions: The H2-FAILS score accurately predicts 30-day mortality after surgery for spinal metastasis. Level of Evidence: Prognostic level III. [ABSTRACT FROM AUTHOR]

Introduction: The number of reoperations increases with the growing number of operations performed. Methods: The clinical material included a group of 2194 patients treated surgically due to degenerative disease of the lumbar spine; we selected a total of 332 patients who were reoperated, and the indications for reoperation were analysed. Results: The percentage of patients operated due to adjacent segment disease in the group of patients with stabilization was on average 8.9%. Conclusions: Indications for stabilizing or preservation of the mobility of the operated segment should provide for the nature of the lesions, and anatomical and surgical conditions.

Degenerative changes in the spinal ligaments, such as hypertrophy or ossification, are important pathophysiological mechanisms of secondary spinal stenosis and neurological compression. Extracellular matrix (ECM) remodeling is one of the major pathological changes in ligament degeneration, and in this remodeling, ECM proteinase-mediated degradation of elastin and collagen plays a vital role. Zinc-dependent endopeptidases, including matrix metalloproteinases (MMPs), a disintegrin and metalloproteinases (ADAMs), and ADAMs with thrombospondin-1 motifs (ADAMTSs) are key factors in ECM remodeling. This review aims to elucidate the underlying mechanisms of these metalloproteinases in the initiation and progression of spinal ligament degeneration. We clarify current literature on the dysregulation of MMPs/ADAMs/ADAMTS and their endogenous inhibitors in degenerative spinal ligament diseases. In addition, some instructive information was excavated from the raw data of the relevant high-throughput analysis. The dysregulation of metalloproteinases and their endogenous inhibitors may affect ligament degeneration by involving several interrelated processes, represented by ECM degradation, fibroblast proliferation, and osteogenic differentiation. Antagonists of the key targets of the processes may in turn ease ligament degeneration. [ABSTRACT FROM AUTHOR]
