Filter by:The primary purpose of this study is to assess the effect size of the change in Oswestry Disability Questionnaire (ODQ) score over the 8 week follow-up period between the video based instruction or standard of care hand-out with pictures and written instructions for subjects meeting the clinical prediction rule for lumbar stabilization. The second purpose will be to determine if there is a subset of physical examination and self-reported variables that are associated with having a successful result (ODQ improvement by at least 6 points) and if the subset of variables are affected by whether or not the subject was in the intervention (video) or control (handout) group.
The purpose of this study is to demonstrate the non-inferiority of AttraX® Putty as a bone graft substitute for autograft in instrumented posterolateral fusion of the thoracolumbar spine, in terms of efficacy and safety.
Lumbar spinal fusion was introduced approximately 70 years ago and has evolved as a treatment option for symptomatic spinal instability, spinal stenosis, spondylolisthesis, and degenerative scoliosis. Many techniques evolved since then, from wiring, rods, pedicle screws, and recently inter-spinous fixation devices like the Aspen. Along its evolutionary trail, various methods for achieving circumferential fusion have arisen. Distinct from staged anterior/posterior fusion techniques, two methods of achieving an interbody fusion from a posterior approach have emerged: posterior lumbar interbody fusion (PLIF) and transforaminal lumbar interbody fusion (TLIF). Recently, the lateral approach for interbody fusion (XLIF) has became a more common technique, requiring in some cases, complemental posterior fixation with pedicle screws, facet screws or interspinous fixation devices like the Aspen device. In this study, we address the clinical and radiological outcome of a novel technique using standard PLIF interbody fusion and insertion of the Aspen device via posterior lumbar approach.
