Accelerated Degeneration of the Segment Adjacent to a Lumbar Fusion
Spine, 1988Previously reported biomechanical studies on the effects of various types of spinal fusion procedures upon the adjacent segment indicate a significant degree of increased stress at that segment. This study presents 18 patients in whom new symptoms developed from the segment adjacent to a fusion after an average symptom-free interval of 8.5 years (1-38 ...

Management of Adjacent Segment Degeneration and Spinal Stenosis (Scar)
Seminars in Spine Surgery, 2008Adjacent segment degeneration after previous lumbar procedures can lead to recurrent symptoms. While many studies have examined the predisposing factors that may contribute to adjacent segment degeneration, few have outlined the management of this condition once it develops. This article reviews the risk factors and diagnostic workup of lumbar adjacent

Finite Element Analysis in Adjacent Segment Degeneration After Lumbar Fusion
International Journal of Medical Robotics and Computer Assisted Surgery, 2011AbstractBackgroundAdjacent segment degeneration (ASD) following lumbar fusion has been well documented in recent years. However, the pathogenesis of ASD is not clear. To investigate this issue, we established a finite element model of segments L2–L5, simulated a single‐segment posterior fixation in L3–L4 and investigated the stress variation and the ...

Adjacent segment disease (ASD) has been described as a frequent complication after a lumbar spinal fusion procedure, though its incidence and the factors related to its appearance are not well established. The radiographic signs that identify ASD in unfused segments may be a consequence of biomechanical changes induced by the fusion procedure.

Adjacent segment degeneration after fusion spinal surgery—a systematic review
International Orthopaedics, 2018Adjacent segment degeneration (ASDeg) and disease (ASDis) have become major concerns after fusion surgery. However, there is no definitive data or knowledge about the incidence or risk factors. The review discusses the incidence and risk factors and prevention of ASDeg and ASDis in the relevant literature.We performed a systematic review of meta ...

To explore the effect of facet joint degeneration in adjacent segments on the incidence of adjacent segment disease (ASD) after lumbar fusion and fixation.A retrospective analysis was performed on 138 patients who underwent L5S1 posterior lumbar interbody fusion (PLIF) from June 2016 to June 2019.

The biomechanics of adjacent segment degeneration
Adjacent segment degeneration (ASD) remains the major long-term complication after lumbar spinal fusion surgery, affecting a third of patients within 5 years postoperation. Despite numerous investigations, there is no consensus on the underlying mechanisms leading to ASD. This thesis aimed to identify knowledge gaps from existing clinical knowledge andopenaire +1 more source
