Does 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 کاملDoes Disc Space Height of Fused Segment Affect Adjacent Disc Degeneration in Anterior Lumbar Interbody Fusion? A Radiological Study
BACKGROUND The restoration of disc space height (DSH) is essential in anterior lumbar interbody fusion (ALIF), while it is unclear whether the reduction of DSH may alter the mechanical status and adversely affect adjacent segment, and few literatures focused on the subject. METHODS Ninety five patients who had undergone ALIF for degenerative disc disease at our institution between March 2004 ...
متن کاملDoes TLIF aggravate adjacent segmental degeneration more adversely than ALIF? A finite element study.
AIM To determine whether transforaminal lumbar interbody fusion aggravate adjacent segmental degeneration more adversely than anterior lumbar interbody fusion. MATERIAL AND METHODS A normal finite element model, an anterior lumbar interbody fusion model and a transforaminal lumbar interbody fusion model of L3-5 were developed. 800 N compressive loading plus 10 Nm moments simulating flexion, e...
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...
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 ...
