As a result of rapid advances in the field of spinal instrumentation, the surgeon today has at his disposal many well-designed implants, such as pedicle screws, hooks, rods, plates, and interbody fusion devices. Many of these implants are modular and are used in combination, such as hooks and screws attached to rods, allowing the surgeon flexibility in selecting the appropriate implants to meet...

BACKGROUND Lumbar spinal stenosis is the most common reason for spinal surgery in elderly patients. However, the surgical management of spinal stenosis is controversial. The aim of this review was to list aspects a surgeon considers when choosing a specific type of treatment. METHODS Appraisal of arguments reported in randomized controlled trials (RCTs) included in systematic reviews publishe...

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 Failure of pedicle screw fixation is often seen in patients with severe osteoporosis. We developed new lumbar spinal instrumentation (Tadpole system) for elderly patients who have osteoporotic bone and poor general health status. The objective of this study was to document the long-term clinical outcomes after Tadpole system fixation, the rate of spinal fusion, the incidence of adjac...

STUDY DESIGN Systematic review. OBJECTIVE To identify whether there is an advantage to instrumented or noninstrumented spinal fusion over decompression alone for patients with degenerative lumbar spondylolisthesis. SUMMARY OF BACKGROUND DATA The operative management of degenerative spondylolisthesis includes spinal decompression with or without instrumented or noninstrumented spinal fusion....

 Abstract Background: Correction of severe kyphosis is a challenging operation in spinal surgery. A two stage operation has been commonly used: anterior release and decompression followed by posterior correction and fusion. We describe the posterior vertebral osteotomy technique for correction of severe and rigid kyphosis through posterior-only approach. Methods: Twelve patients (six male and s...

Loss of sagittal alignment and balance in adult spinal deformity can cause severe pain, disability and progressive neurological deficit. When conservative treatment has failed, spinal fusion using rigid instrumentation is currently the salvage treatment to stop further curve progression. However, fusion surgery is associated with high revision rates due to instrumentation failure and proximal j...

Lumbar spinal fusions have been performed for spinal stability, pain relief and improved function in spinal stenosis, scoliosis, spinal fractures, infectious conditions and other lumbar spinal problems. The success of lumbar spinal fusion depends on multifactors, such as types of bone graft materials, levels and numbers of fusion, spinal instrumentation, electrical stimulation, smoking and some...

Purpose Parkinson’s Disease (PD) patients are a high-risk population in adult spinal surgery and there is no general consensus regarding the surgical correction of spinal deformity in these patients. We perform long fusion for PD spinal deformity in our institution and this study is a retrospective assessment of the radiological and clinical outcomes of posterior spinal fusion with instrumentat...
