abstract   background: to evaluate proximal junctional segment changes in adolescent idiopathic scoliosis(ais) the posterior spinal fusion and also instrumentation also and finding of probable risk factors, were all considered in this study.   methods: we retrospectively reviewed radiographs of 121 consecutive patients who underwent posterior spinal fusion for ais from t3 or below, with a mean ...

Background: Post operative lumbar disc space infection is relatively uncommon. The anterior approach has been the traditional surgical approach for treatment of this complication. Posterior approach was sometimes added for instrumentation only. Purpose: To present the results and clinical outcome, at a minimum of twelve months, following transforaminal lumbar interbody fusion (TLIF) and posteri...

The use of titanium cages for posterior lumbar interbody fusion (PLIF) has gained popularity because it offers the advantages of anterior column support and stabilization. However, cage migration into the spinal canal may have severe or disastrous consequences. Here, the authors report an unexpected case of posterior migration of fusion cages after screw removal in a patient that underwent PLIF...

OBJECTIVE Spinal fusion operation is an effective treatment in the spinal pathology, but it could change the physiological distribution of load at the instrumented and adjacent segments. This retrospective study compared the radiological and clinical outcomes of patients undergoing lumbar fusion with semirigid rods versus rigid rods system. METHODS Using transpedicular fixation and posterior ...

Lumbar degenerative disease (LDD) refers to the normal strain of body involving lumbar bone, ligament, intervertebral disc, thereby protruding slippage, spinal stenosis and other lesions. fusion surgery has been proved be an effective strategy for treatment LDD. At present, a variety methods such as anterior posterior have reported. This article aims review discuss reported strategies LDD relat...

Lumbar fusion is commonly performed to alleviate chronic low back and leg pain secondary to disc degeneration, spondylolisthesis with or without concomitant lumbar spinal stenosis, or chronic lumbar instability. However, the risk of iatrogenic injury during traditional anterior, posterior, and transforaminal open fusion surgery is significant. The axial lumbar interbody fusion (AxiaLIF) system ...

Fusion and rigid instrumentation have been currently the mainstay for the surgical treatment of degenerative diseases of the spine over the last 4 decades. In all over the world the common experience was formed about fusion surgery. Satisfactory results of lumbar spinal fusion appeared completely incompatible and unfavorable within years. Rigid spinal implants along with fusion cause increased ...

BACKGROUND Venous thromboembolism (VTE) is a significant cause of morbidity and mortality in orthopaedic surgery. While specific guidelines exist for hip and knee arthroplasty, there is wide variation in VTE prophylaxis in complex spinal surgery. This study sought to determine the incidence of VTE, and risk factors associated with VTE, in patients undergoing elective instrumented posterior lumb...

Lumbar stenosis is a well-defined pathologic condition with excellent surgical outcomes. Empiric evidence as well as randomized, prospective trials has demonstrated the superior efficacy of surgery compared to medical management for lumbar stenosis. Traditionally, lumbar stenosis is decompressed with open laminectomies. This involves removal of the spinous process, lamina, and the posterior mus...
