We recently showed that, after traumatic spinal cord injury (TSCI), laminectomy does not improve intraspinal pressure (ISP), spinal cord perfusion pressure (SCPP), or the vascular pressure reactivity index (sPRx) at the injury site sufficiently because of dural compression. This is an open label, prospective trial comparing combined bony and dural decompression versus laminectomy. Twenty-one pa...

Clinical reports have suggested that myelography and laminectomy may produce more arachnoiditis than myelography alone. The effect of experimental lumbar myelography and laminectomy on arachnoiditis in monkeys was studied. Arachnoiditis was as severe after myelography alone as after myelography and laminectomy. Minimal arachnoiditis was found myelographically and histologically after myelograph...

A ligamentous, nonlinear, sliding contact, three-dimensional finite element (FE) model of L2-L3 complex was developed to investigate the biomechanical effect of laminectomy with and without facetectomy. The L2-L3 FE model was validated against experimental study under various physiological loadings and found to match well with the experimental data. Four iatrogenic models (unilateral laminectom...

Spinal kyphotic deformity after spinal laminectomy or laminoplasty is more common in pediatric patients than adults. Laminectomy can lead to decreased cartilage growth, anterior wedging and posterior spinal muscle insufficiency which can result in kyphotic deformity. Herein we outline a case report of a child presenting with kyphotic deformity after receiving a spinal laminectomy to treat a pen...

STUDY DESIGN Seventy-five patients who had been treated for lumbar spinal stenosis (LSS) were reviewed retrospectively. PURPOSE Invasion into the paravertebral muscle can cause major problems after laminectomy for LSS. To address these problems, we performed spinous process-splitting laminectomy. We present a comparative study of decompression of LSS using 2 approaches. OVERVIEW OF LITERATU...

STUDY DESIGN A retrospective study of intradural extramedullary tumor. OBJECTIVE To compare the treatment results in the different surgeries of spinal intradural extramedullary tumor. METHODS The study retrospectively reviewed 122 patients. The minimally invasive surgery (MIS) group was divided into Group A (hemilaminectomy + tumor microscopic excision) and Group B (laminectomy + tumor micr...
