Filter by:The aim of the present study is to investigate the safety and clinical utility of contralateral oblique view for fluoroscopic guided cervical epidural access.
A prospective double-blind, randomized controlled trial investigating the effect of a single-dose of intraoperative methadone in patients undergoing spinal fusion.
This is a prospective, randomized clinical trial of patients undergoing 1-level lateral lumbar spinal fusion. This study seeks to randomize patients indicated for Lateral Lumbar Interbody Fusion (LLIF) into one of two groups: direct decompression and indirect decompression.
The photographical and functional parameters of paravertebral muscle in patients with lumbar spinal stenosis will be measured to investigate the correlation between paravertebral muscle degeneration and symptoms and prognosis of patients.By measuring the parameters of paravertebral muscle with normal people, the differences between the patients and normal people will be compared to establish an appropriate paravertebral muscle evaluation method.
Background: A significant portion of cardiac amyloidosis patients have a 5 to 10 years prior history of spinal canal stenosis, reflecting a diagnostic red flag that should raise suspicion for amyloidosis presence. Mild troponin release and NT-proBNP elevation, both serum cardiac biomarkers, often coincide with cardiac amyloidosis. Early cardiac amyloidosis treatment improves survival, warranting timely diagnosis. Study aim: to test a prospective screening strategy, based on serum cardiac biomarkers, to increase early detection of cardiac amyloidosis in patients with spinal canal stenosis. Design: Single-centre prospective observational non-interventional diagnostic study. Methods: Consecutive patients during a one-year period in AZ Sint-Jan Bruges, without known cardiac amyloidosis history and scheduled for spinal canal stenosis surgery, will have cardiac evaluation including serum cardiac biomarker (high-sensitive troponin T and NT-proBNP) assessment, electrocardiography and transthoracic echocardiography. During surgery, all patients will undergo ligamentum flavum biopsy to evaluate presence and burden of transthyretin amyloid deposition (Congo-red staining and immune histochemistry). All patients with suspicion for cardiac amyloidosis will undergo further diagnostic testing (including laboratory test and bone scintigraphy). A chronologic cascade screening process will be used starting with abnormal serum cardiac biomarkers (high-sensitive troponin T ≥ 14 ng/ml and/or NT-proBNP > 125 pg/ml), followed by electrocardiography, transthoracic echocardiography and finally ligamentum flavum biopsy results. The diagnostic performance of this biomarker-based strategy will be compared to electrocardiography, echocardiography and ligamentum flavum biopsy. Conclusion: It is hypothesised that serum cardiac biomarker testing in patients undergoing spinal canal stenosis surgery represents a simple and valuable prospective screening strategy for early detection of cardiac amyloid(osis).
Introduction Lumbar spinal epidural lipomatosis (SEL) is a rare condition defined by an excessive deposition of adipose tissue in the lumbar spinal canal. The objective of this case report is to document a clinical case of SEL presenting within a multidisciplinary spine clinic and to compare our clinical findings and management with the current literature. Case presentation A 51-year-old female presented at a spine clinic with low back pain, bilateral leg pain and difficulty walking. MR imaging of the lumbar spine showed L4-L5 and L5-S1 degenerative disk disease with evidence of severe central canal stenosis due to extensive epidural lipomatosis. The patient was initially advised to lose weight, undergo a course of physiotherapy, and consult with the pain clinic. Because of lack of improvement, the patient was scheduled for L4-S1 posterior spinal decompression and L4-L5 posterior spinal instrumented fusion. Discussion The discussion will include the diagnosis of SEL, imaging appearance, its risk factors, etiology and management. Conclusion This case report describes a case of lumbar spinal stenosis due to SEL with neurological symptoms. Some risk factors have also been identified in the literature. MRI is considered as the reference standard for its diagnosis. The therapeutic approach of patients with SEL is not standardized. Thus, reporting and investigating the diagnostic process and treatment of this patient will positively contribute to better management for other future patients.
This single-group cross-sectional cohort study will enroll approximately 25 patients at the North Texas VA Health Care System (VANTHCS) who have previously received off-label prescriptions of misoprostol for lumbar spinal stenosis for any duration and who are willing to provide verbal and informed consent. Patients will answer a questionnaire regarding pain and functional improvement especially in reference to misoprostol treatment. Patients will also be selected to have their walking tolerance (claudication distance) measured in an outpatient clinic setting to determine the severity of their lumbar spinal stenosis symptoms after having received misoprostol.
The primary objective of the study is a data collection initiative. The study will collect clinical and radiographic outcomes of patients implanted with patient specific rods. The secondary objective is to collect clinical and radiographic outcomes of patients with hardware as a control cohort to the patient-specific rods.
The purpose of this study is to determine the effectiveness of minimally invasive decompression and fusion over the traditional open decompression and fusion in patients with single-level lumbar stenosis caused by degenerative spondylolisthesis. Postoperative follow-up will continue for 12 months. Сlinical, safety, radiological and cost-effectiveness endpoints will be evaluated.
There is a critical need to target physical activity during postoperative management to optimize long-term recovery after lumbar spine surgery. The overall objective of this study is to conduct a two-group randomized control trial (RCT) to examine the feasibility and acceptability of a physical activity telehealth intervention delivered by a physical therapist for improving disability, physical function, pain, and physical activity compared to usual care after spine surgery for a degenerative lumbar condition. The physical activity intervention will include wearable technology and remote physical therapist support to counsel patients on a realistic progression of physical activity (steps per day). The central hypothesis is that this 8-week physical activity intervention performed at two weeks after surgery will be feasible and acceptable. The results of our randomized trial will be used to support a large multi-site clinical trial to test the effectiveness and implementation of this intervention
