Filter by:In this study, we will use advanced and newly available MR imaging techniques at 3 Tesla (including in situ axial loading and quantitative T1rho, T2, and diffusion measurements) to assess the intervertebral discs and adjacent vertebrae in patients with lumbar back pain scheduled for back surgery (n=20), patients with degenerative disease without classic discogenic back pain (n=10), patients who had discectomies for herniated discs (n=5), and age-matched volunteers without back pain (n=10). In all patients standard imaging procedures will also be performed, including radiographs, standard MRI at 1.5 Tesla and discography. All patients will have specimen of the intervertebral disc harvested at surgery and pathologic analysis and spectroscopy of these specimen will be performed. Post-surgical findings/outcome combined with discography will serve as a standard of reference for the identification of the painful disc(s). The diagnostic performance of the new techniques in assessing the painful disc will be evaluated. We will collect disc specimens from 50 patients undergoing back surgery but did not have pre-surgical MR imaging. These disc specimens will be analyzed in the same manner as the specimens collected from surgical patients who had pre-surgical MRI. This study will serve as a pilot study for a larger project focusing on advanced imaging of the painful intervertebral disc. We hypothesis that advanced, dedicated MR examinations at 3T can identify painful degenerated discs in patients with chronic lumbar back pain.
The purpose of the study is to evaluate the performance of the Discover cervical Artificial disc in the treatment of degenerative disc disease in one level of the cervical spine.
Until now, arthrodesis (intervertebral fusion) is the formal treatment for the lumbar and cervical degenerative disc disease : arthrodesis has been the standard surgical treatment for the patients when nonsurgical management has failed. However , it has shown out some drawbacks : pseudoarthrosis may appear in the short term, and junctional degeneration in the long term. The replacement of the intervertebral disc by a prosthesis (arthroplasty) has been since a few years a major alternative therapeutic to the arthrodesis.: it demonstrates great functional results and less post-interventional complications. It is indicated to restore a normal function of the spine (motion is kept)and to avoid deterioration of the adjacent spinal segments over the long time. In this clinical study, we will distinguish the cervical discal pathology and the lumbar discal pathology. The purpose of this study is to analyze the results of the arthroplasty in terms of functional effects, quality of life, anatomical results and economical results.
The purpose of this study is to establish the safety and effectiveness of the Advent™ Cervical Disc compared to Anterior Cervical Discectomy and Fusion (ACDF) in treating degenerative disc disease at a single-level in the cervical spine (from C3 to C7) following cervical discectomy in skeletally mature patients (at least 18 years of age).
This was a randomized, blinded study of transforaminal epidural injection of clonidine versus a similar injection of corticosteroid for acute lumbosacral radiculopathy. The hypothesis was that clonidine will be as effective as steroid for this condition.
The purpose of this study is to establish the safety and effectiveness of the DIAM™ Spinal Stabilization System in the treatment of moderate single-level lumbar degenerative disc disease.
The purpose of this study is to show that the Kineflex|C Spinal System is no worse than conventional Anterior Cervical Diskectomy with Fusion (ACDF) in patients with single level degenerative disc disease at any cervical level from C3 to C7.
The Kineflex Spinal System is no worse than the Charite Spinal System in patients with single level degenerative disc disease at L4/5 or L5/S1.
The purpose of this study is to compare Optecure™ as an autograft extender (treatment) to autograft alone (control) in patients undergoing 1 or 2 level fusion of the lumbar spine(one level is defined as two adjacent vertebrae), L2 and below. The primary endpoint will be the assessment of fusion by evaluation of x-rays taken following surgery at each visit. The x-ray evaluation will be conducted by a radiologist who is blinded to the type of treatment each patient has received. Subjects will be seen at 6 weeks, 3 months, 6 months, 12 months, and 24 months postoperative (post-op). Questionnaires and x-rays will be completed at each visit and a computed tomography (CT) scan will be taken at the 12 month visit(and used to aid in assessment of bridging bone, where appropriate).
