Traumatic spondylolisthesis of the lumbar spine is uncommon and can result in canal narrowing and spinal cord injury. Early decompression promotes recovery of neurological function. We report 3 such cases: one in the lumbosacral joint and 2 in the lumbar spine. The former patient had an open fracture-dislocation and underwent (delayed) posterior decompression and instrumentation without interbo...

We describe two patients with an atypical congenital kyphosis in which a hypoplastic lumbar vertebral body lay in the spinal canal because of short pedicles. There were no defects in the posterior elements, or any apparent instability of the facet joints. Both patients were treated successfully by anterior fusion to the levels immediately above and below the affected vertebra, and posterior fus...

BACKGROUND Traditional approaches to deformity correction of degenerative lumbar scoliosis include anterior-posterior approaches and posterior-only approaches. Most patients are treated with posterior-only approaches because the high complication rate of anterior approach. Our purpose is to compare and assess outcomes of combined anterior lumbar interbody fusion and instrumented posterolateral ...

STUDY DESIGN Retrospective study. PURPOSE To determine if posterior surgery alone can satisfactorily treat post-traumatic kyphosis (PTK). OVERVIEW OF LITERATURE One of the worst complications of vertebral fractures is PTK. The type of surgery and approach to treat a symptomatic and refractory PTK is a challenging issue in spinal surgery, and yet, there is no specific treatment algorithm. ...

INTRODUCTION The goal of lumbar spinal fusion is to limit pain by decompression and removal of soft tissues, followed by the formation of a rigid bony union between adjacent vertebrae. The general consensus for a rigid fusion construct requires careful preparation of the intervertebral space and the creation of a rigid fusion construct. Anterior lumbar interbody fusion (ALIF) provides good acce...

BACKGROUND There is considerable controversy about the long-term morbidity associated with the use of posterior autologous iliac crest bone graft for lumbar spine fusion procedures compared with the use of bone-graft substitutes. The hypothesis of this study was that there is no long-term difference in outcome for patients who had posterior lumbar fusion with or without iliac crest autograft. ...

The aim of this study was to observe the clinical effects of bilateral decompression via vertebral lamina fenestration for lumbar interbody fusion in the treatment of lower lumbar instability. The 48 patients comprised 27 males and 21 females, aged 47-72 years. Three cases had first and second degree lumbar spondylolisthesis and all received bilateral vertebral lamina fenestration for posterior...

To the authors' knowledge, no comparative studies exist of venous thromboembolism (VTE) based on different pathologies, surgical procedures, or spinal levels after spinal surgery. The authors prospectively investigated VTE after elective spinal surgery. The study comprised 4 patient groups. Group 1 comprised 79 patients with lumbar spinal stenosis treated with posterior decompression without fu...

Paraspinal muscles are commonly affected during spine surgery. The purpose of this study was to assess the potential factors that contribute to paraspinal muscle atrophy (PMA) after lumbar spine surgery. A comprehensive review of the available English literature, including relevant abstracts and references of articles selected for review, was conducted to identify studies that reported PMA afte...

Extensive mechanical loads on the lumbar spine often lead to degenerative damages of spinal structures. In many cases surgical interventions, such as spinal fusion, are unavoidable. An appropriate method for the estimation of the mechanical effects of such interventions to adjacent vertebral segments is the mathematical computer simulation. This paper presents a 3DMultiBodySimulation(MBS-) mode...
