Active clinical trials for "Spinal Stenosis"

The primary objective is to determine the validity of the Six-Minute-Walking Test (6WT) and Timed-Up and Go (TUG) test to measure objective functional impairment (OFI) in patients undergoing either interlaminar epidural steroid injection (ESI) or transforaminal epidural steroid injections (TFESI) for lumbar degenerative disc disease (DDD)

The investigators will prospectively evaluate for the presence of amyloid deposits in ligamentum flavum (yellow ligament) tissue samples obtained from patients undergoing spinal stenosis surgery. Patients who have tissue that stains positive for amyloid will be referred to an amyloidosis specialist.

The five-repetition sit-to-stand test (5R-STS) has been used in many medical disciplines, but has never been correlated with or validated in regard to degenerative spinal diseases. The investigators aim to assess the possibility of using the standardized 5R-STS as an objective measure of functional impairment and pain severity in patients with degenerative lumbar spinal diseases.

The study determines the reliability and validity of the 6-Minute Walking Test (6MWT) in patients with lumbar degenerative disc disease (DDD).

To compile real-world outcomes of the Superion™ IDS in routine clinical practice.

Purpose To evaluate clinical and radiologic outcome of a series of patients treated with a removable percutaneous interspinous process spacer (IPS) (LobsterProject® Techlamed®) for symptomatic degenerative lumbar spinal stenosis (DLSS). Methods All patients treated in the two considered Centres with this IPS during 2019 were retrospectively reviewed. Patients with incomplete clinical or radiological documentation were not included. Procedures were performed under deep sedation or general anaesthesia by two interventional radiologists. Patients were clinically evaluated before intervention and at 3-month follow-up with Visual Analog Scale for pain (VAS), Oswestry Disability Index (ODI) and radiologically with MRI or CT scans. Neural foramina were independently measured for each patient on pre- and post-procedural CT scans by two radiologists.

The rate of success 12 months after surgery is reported to be 60-65% in patients with lumbar disc herniation and 60-70% in patients with spinal stenosis. At the Back Center Copenhagen, patients with persistent low back pain caused by lumbar disc herniation and spinal stenosis are treated by a multidisciplinary team comprising rheumatologists, physiotherapists, chiropractors, and social workers according to current guidelines. Therefore we have a unique opportunity to report the long term outcome in candidates for surgery, regardless of whether they have surgery or not, after having received optimal but unsuccessful nonsurgical treatment. The purpose of this study is to answer the following questions: 1) What is the proportion of patients operated upon after referral to surgical evaluation with positive MRI findings, persistent low back pain, and poor outcome following non-operative treatment? 2) What was the outcome in these patients 2 years following referral? 3) Where any baseline variables predictive of good or poor postsurgical outcome? 4) Where there any difference in outcome in patients with or without surgery?

This is a prospective, non-randomized (single arm), multi-center, post-market clinical study designed to evaluate FIBERGRAFT® BG Matrix mixed with autograft and bone marrow aspirate in up to 150 subjects with degenerative disc disease (DDD) with or without radiculopathy, or spinal stenosis and/or spondylolisthesis requiring a fusion. The patient population will include adult (skeletally mature) men and women undergoing 1 or 2 level fusion in the lumbar spine (L2-S1) who are deemed eligible for the study, characterized by inclusion and exclusion criteria.

Introduction: Lumbar spinal stenosis is a common cause of low back and leg pain in elderly impacting physical activity and quality of life. Initial treatments are non-surgical options. If unsuccessful, surgery is advocated. The literature is not clear as to the outcome of surgery when compared to non-surgical treatment, and the optimal time for surgery is not explicit. Materials and analysis: This observational study is designed to investigate the course of treatment, compare effectiveness of surgical and non-surgical treatment in patients with lumbar spinal stenosis, and identify prognostic factors for outcome in the context of current clinical practice. Prospectively registered data on treatment, outcome and patient characteristics are collected from nationwide registers on health and social issues, a clinical registry of people with chronic back pain and hospital medical records. Primary outcome is change in physical function measured by the Zurich Claudication Questionnaire. Secondary outcomes are changes in symptom severity, pain-related function, health-related quality of life, and general self-efficacy. All outcomes are measured at baseline, 6 months and 12 months follow up. Comparisons on these variables will be made between those who undergo surgery for lumbar spinal stenosis and those not receiving surgery at 12 months follow up according to different analysis populations. Prognostic factors include treatment allocation, back and leg pain intensity, comorbidity, duration of symptoms, pre-treatment function, self-rated health, income, general self-efficacy and magnetic resonance imaging graded compression of central stenosis. Ethics and dissemination: The study has been evaluated by The Regional Committees on Health Research for Southern Denmark (S-20172000-200) and notified to the Danish Data Protection Agency (17/30636). All participants provide consent. Findings will be disseminated in peer-reviewed publications and presented at national and international conferences following the guidance from the STROBE and PROGRESS statement. Potential sources of bias will be addressed using ROBINS-I.

The purpose of this study is to evaluate the clinical performance of the iO-Flex® System in reducing pain and symptom severity in patients with one or two level lumbar spinal stenosis that requires surgery.
