Active clinical trials for "Spondylolisthesis"

The primary purpose of this study is to track and document the clinical outcomes of patients with radicular pathology following posterior lateral fusion with the Dynesys Spinal System. Secondary purpose of this study is to assess outcomes with historical controls along a continuum of motion and anatomy sparing procedures.

The purpose of this open, multi-center study is to prospectively collect outcome data on patients who are having lumbar spinal fusion surgery with implantation of the SpineLink® system.

The purpose of the study is to prospectively measure pain, function, and patient satisfaction in 70 consecutive patients treated by lumbar fusion using the Triad allograft. Results of the Triad allograft will be compared to those of other anterior lumbar interbody fusion (ALIF), transforaminal lumbar interbody fusion (TLIF), and posterior lumbar interbody fusion (PLIF) surgeries. Patient participation is based on the physician determination that the patient requires one of these surgeries. Participants will be evaluated pre-operatively and post-operatively at 3, 6, 12,and 24 month intervals. Clinic procedures will be related to standard of care except for the completion of several study questionnaires: Back Pain Questionnaire; Oswestry Disability Index Questionnaire; Short Form-36 (SF-36) Survey; Visual Analog Pain Scale (VAS); and The Modems Patient Satisfaction Survey. Outcome Measurements: The patient's pain is scored by a VAS normalized to 100; Patient function is based on Oswestry scores; General health is assessed by SF-36 completion; and Overall patient satisfaction will be determined by the completion of the Modems.

This study aims to evaluate clinical and radiological outcomes of isthmic spondylolisthesis surgically treated with combined approach. The goal is to demonstrate that it is a safe and efficient technique to treat isthmic spondylolisthesis. There is very little literature concerning this procedure.

Prospective study, not randomised, non-interventional, monocentric, investigating an intended patient cohort of 60 patients already operated on the cervical spine due to degenerative disc disease of the cervical spine down to the first thoracolumbar VBR (C2-T1), who received a Quintex plate for stabilisation

Age related changes in the lumbar spine can lead to narrowing of the spinal canal (spinal stenosis) causing leg and back pain. Spinal stenosis can be associated with a misalignment of the spine caused by forward slippage of a vertebrae over another. This instability is diagnosed using diagnostic imaging. With signs of instability the spine surgeon might choose a fusion of the vertebrae. This is a more complex procedure in relation to the simple decompression preformed without instability for spinal stenosis. The purpose of this study is to identify characteristics of instability of the lumbar spine on diagnostic imaging, and investigate associations with surgical data and patient reported outcomes from the National Spine databases from Denmark and Sweden. This will support spine surgeons in providing evidence-based surgical treatment for spinal stenosis with or without signs of instability

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.

This study is to evaluate the anatomical characteristics of spondylolisthesis patients using spine ultrasound imaging. The optimal angle of spinal needle insertion for spinal anesthesia in spondylolisthesis patients was compared to that of normal patients without abnormal spinal anatomy.

The objective of the PMCF is to collect outcome information on patients suffering from symptomatic degenerative disc disease or degenerative spondylolisthesis requiring 1- or 2-level lumbar or lumbar-sacral spinal fusion with posterior instrumentation and therefore receiving the icotec CF/PEEK Pedicle System in combination with the icotec CF/PEEK TLIF Cage ETurn™.

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.
