Adjacent segment degeneration
Adjacent segment disease (ASD) is defined as degeneration that develops at mobile segments above or below a fused spinal segment and usually develops after spinal fusion or other back surgeries. Nearly 5 decades ago, the medical findings related to ASD were usually released in case reports as a relatively unusual complication of lumbar or lumbosacral fusions. Since the initial reports, ASD has ...
متن کاملAdjacent Segment Degeneration after Single-Level PLIF: Comparison between Spondylolytic Spondylolisthesis, Degenerative Spondylolisthesis and Spinal Stenosis
STUDY DESIGN A retrospective study. PURPOSE To comparatively investigated the rate of the adjacent segment degeneration and the clinical outcomes in patients with spondylolytic spondylolisthesis, spinal stenosis or degenerative spondylolisthesis. OVERVIEW OF LITERATURE There have been few studies reported on the adjacent segment degeneration following posterior lumbar interbody fusion(PLIF)...
متن کاملAdjacent segment degeneration in the lumbar spine.
BACKGROUND A primary concern after posterior lumbar spine arthrodesis is the potential for adjacent segment degeneration cephalad or caudad to the fusion segment. There is controversy regarding the subsequent degeneration of adjacent segments, and we are aware of no long-term studies that have analyzed both cephalad and caudad degeneration following posterior arthrodesis. A retrospective invest...
متن کاملevaluation of adjacent segment degeneration after cervical spine surgery: arthroplasty versus fusion
background : anterior cervical discectomy and fusion (acdf) is an effective treatment for disc herniations ; but some studies demonstrated that in the untreated levels adjacent to a fusion, increased motion might lead to an increased risk of adjacent segment degeneration (asd). on the other hand, methods of cervical disc arthroplasty (cda) have improved. the aim of this study is to evaluate and...
متن کاملAdjacent Segment Motion After Lumbar Fusion
t I I Study Design. For in vitro studies, there is no basis t for choosing a "load control study" over a "displace: ment control" study. This study qualitatively compared f results from in vitro and in vivo tests, allowing the au€ : thors to address the experimental assumptions that in vitro testing contributes to the understanding of the in vivo condition. Objectives. To compare motion changes...
