Topping-off technique prevents aggravation of degeneration of adjacent segment fusion revealed by retrospective and finite element biomechanical analysis
AIM The aim of this study was to evaluate the effect of the Topping-off technique in preventing the aggravation of degeneration caused by adjacent segment fusion. METHODS Clinical parameters of patients who underwent L5-S1 posterior lumbar interbody fusion + interspinous process at L4-L5 (PLIF + ISP) with the Wallis system (Topping-off group) were compared retrospectively with those of patien...
متن کاملDoes disc space height of fused segment affect adjacent degeneration in ALIF? A finite element study.
AIM The restoration of disc space height of fused segment is essential in anterior lumbar interbody fusion, while the disc space height in many cases decreased postoperatively, which may adversely aggravate the adjacent segmental degeneration. However, no literature available focused on the issue. MATERIAL AND METHODS A normal healthy finite element model of L3-5 and four anterior lumbar inte...
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 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 following spinal fusion for degenerative disc disease.
Fusion has become the standard of care for numerous pathologic conditions of the spine over the past 50 years. Instrumented thoracolumbar fusion for adolescent and adult spinal deformity has enjoyed great success in arresting the progression of and correcting scoliotic deformity. In the cervical spine, decompression and fusion have provided a greater than 90% likelihood of relieving radicular s...
