Active clinical trials for "Spondylolisthesis"

Establish a data repository of patients who have undergone single, two-, or three-level lumbar instrumented arthrodesis procedures supplemented by the Implanet Jazz System.

The purpose of this clinical investigation is to evaluate the clinical outcomes of subject with spondylolisthesis undergoing posterolateral fusion (PLF) surgery utilizing the Aspen™ Spinous Process Fixation System. The Aspen™ device will be evaluated using Oswestry Disability Index (ODI) improvement and success of fusion.

This is a prospective, multi-center controlled observational clinical study. All subjects will receive Titan Endoskeleton TT/TO acid etched titanium implant for the planned procedure. Each site will have a predetermined bonegraft extender to be used in all enrolled subjects at that site.

The overall goal of this clinical study is to characterize the fusion rate of geneX® ds bone graft substitute in comparison to autograft, which is considered the gold standard for posterolateral fusion. Assessments are made using AP and Lateral x-rays, F/E x-rays, and CT scans geneX® ds has been cleared by the FDA for use in these procedures; however this study will allow more detailed characterization of geneX® ds performance in the long-term (1 year). By using the patient as their own control, direct comparison to autograft can be performed while minimizing other variables.

Patients with degenerative lumbar spondylolisthesis usually are present with low back pain, muscle spasm and weakness, radicular symptoms, intermittent claudication, insomnia, even urine or stool incontinence. There are very few research on the effectiveness of core spine stabilization exercise, balance training, and the balance effect while wearing lumbar corset in these patients. Purpose: To investigate 1) the correlation of dynamic balance and the degree of disability with the characteristics of spinopelvic alignment. 2) potential predictors of dynamic spino-pelvic instability, 3) the effectiveness of core spine stabilization exercise, balance training and balance effect of the wearing of lumbar corset in patients with degenerative lumbar spondylolisthesis .

The purpose of this study is to assess clinical and radiographic outcomes in patients who undergo three-level oblique lateral lumbar interbody fusion (OLIF) using ViBone, demineralized bone matrix (DBM), and bone morphogenetic protein (BMP). One product will be used on each level. Subjects will be followed for 12 months following surgery to assess degree of mineralization via computed tomography (CT) scan at 6 and 12 months, mean time to fusion, and maturation of fusion mass postoperatively via x-ray radiograph.

The five-repetition sit-to-stand test has been validated and is used primarily in pulmonary medicine and cardiology, and has recently been shown to be a useful tool for the objective assessment of functional impairment in patients with degenerative diseases of the lumbar spine. The goal of this study is to assess the possibility of supervised and unsupervised at-home-assessment. Validation of at-home-assessment would allow the 5R-STS to be easily used as a follow-up tool in clinical trials, for example.

Assess clinical and radiographic outcomes in patients who undergo 1-3 level anterior cervical discectomy fusion (ACDF) or lumbar interbody fusion (TLIF, PLIF, ALIF, or LLIF) using ViBone.

The registry has been designed as a prospective, observational program for patients undergoing lumbar or cervical fusion using VariLift device with the ultimate goal to aid in the development of strategic treatment pathways and improved patient care. All patients who agree to participate in the registry will sign an informed consent form and subsequently be treated by their surgeon with the VariLift device. Potential treatment procedures include bilateral posterior lumbar interbody fusion (PLIF), unilateral transforaminal lumbar interbody fusion (TLIF), or bilateral anterior lumbar interbody fusion (ALIF) for the lumbar spine, or cervical unilateral or bilateral ACDF procedure. Surgical procedures can be performed in either an inpatient or outpatient facility. It is anticipated that the VariLift devices will improve patient outcomes and lead to the development of treatment pathways to improve patient care.

The purpose of this study is to determine differences in the XLIF and TLIF procedures with respect to perioperative variables in adult patients with low-grade symptomatic spondylolisthesis.
