Echocardiography (Mount Kisco, N.Y.), 2002
Hypokinetic myocardium is presumed to be reversibly dysfunctional. However, hypokinetic segments do not necessarily improve after revascularization since their outcome can be influenced by tethering effects of adjacent myocardium. To assess whether hypokinetic segments improve following revascularization, 24 patients underwent resting and dobutamine ...

Analysis of adjacent segment degeneration with laminectomy above a fused lumbar segment
Journal of Clinical Neuroscience, 2013Although recent data suggests that lumbar fusion with decompression contributes to some marginal acceleration of adjacent segment degeneration (ASD), few studies have evaluated whether it is safe to perform a laminectomy above a fused segment. This study investigates the hypothesis that laminectomy above a fused lumbar segment does not increase the ...

Same-segment and adjacent-segment disease following posterior cervical foraminotomy
Journal of Neurosurgery: Spine, 2007Object The cervical foraminotomy was pioneered in the 1940s to address radicular symptoms via a posterior approach, but the long-term outcome has not been adequately studied. Methods The authors retrospectively analyzed data obtained from 303 patients (188 male and 115 female, mean age 49.2 years) who had consecutively undergone a single-level ...

Lumbar Clinical Adjacent Segment Pathology
Spine, 2014Retrospective case series.To evaluate reoperations for lumbar adjacent segment pathology (ASP) during a 10-year period.ASP after lumbar arthrodesis is an important clinical problem. There remains controversy, however, on the distribution of the most commonly affected levels.Thirty-one patients undergoing revision operation for ASP in the lumbar spine ...

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.

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 ...

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
Adjacent segment disease: fact or fiction?
Bone & Joint 360, 2014In medico-legal practice we see a lot of people with vertebral injuries and disc/soft-tissue injuries. There are frequently discussions on the cause of the claimant’s pain and whether it is related to a specific injury or incident or whether it is part and parcel of their constitutional condition.
