Filter by:The studied indication is degenerative conditions of the lumbar spine resulting in back pain with lower extremity symptoms and neurogenic claudication. The purpose of this study is to evaluate the effectiveness and safety of instrumented posterior arthrodesis using the Spinal Simplicity Minuteman G5 MIS Fusion Plate and bone graft material in patients with degenerative conditions of the lumbar spine resulting in chronic low back pain with lower extremity symptoms and concurrent neurogenic claudication.
There has been a long-standing controversy on the operative treatment of Degenerative Lumbar Spondylolisthesis (DLS) with Lumbar Canal Stenosis (LCS), especially whether the addition of fusion to decompression is necessary. Many believe that decompression alone (D) by either using midline preserving fenestration techniques (fenestration by laminotomy and medial facetectomy) or with a spinous process osteotomy (SPO) is enough for treatment of patients with DLS while others believe that a fusion (D+F) should be added in all cases. The study aims to determine if decompression alone performs better or worse in the long term than decompression with fusion in a large cohort of patients who have DLS with LCS. It also aims to determine if the decompression technique of midline-sparing fenestration or spinous process osteotomy make a difference to survival in cases of DLS with LCS.
The objective of this study is to evaluate the safety and performance of NuVasive interbody implants when used during thoracic and/or lumbar spine surgery as measured by reported complications, radiographic outcomes, and patient-reported outcomes. This study is being undertaken to identify possible residual risks and to clarify mid- to long-term clinical performance that may affect the benefit/risk ratios of these interbody implants.
The purpose of this study is to assess the course of hip weakness after LLIF or ALIF procedures. These outcomes include measures of hip strength using a dynamometer, which is a device used to measure muscle strength. While it is known that people experience temporary hip and leg weakness after an LLIF or ALIF, the exact timing of when hip and leg strength is regained after an LLIF or ALIF is not known.
This study is being conducted to evaluate the clinical and radiographic outcomes of three different interbody implant types when used with cancellous allograft chips with BMA or cellular allograft in patients undergoing XLIF surgery. The study will evaluate success by comparing the rate of fusion, complications profile, and any relationships between clinical outcomes (pain and function) and radiographic outcomes (fusion rate) between the three implant groups.
This study investigates the possible differences in images obtained in patients with lumbar spondylolisthesis when positioned in an upright weight bearing position compared with traditional supine positioning for lumbar MRI.
The purpose of this retrospective data review is to evaluate the health economic drivers and complications of two surgical procedures: transsacral lumbar interbody fusion and transforaminal lumbar interbody fusion when used in conjunction with bilateral supplemental screw fixation as an adjunct to fusion. Devices used in both systems are cleared for use and comply with US regulations and requirements.
