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 si...

Lumbar interbody fusion is a common procedure owing to the high prevalence of degenerative spinal disorders. During such procedures, carbon fiber-reinforced polymer (CFRP) cages are frequently utilized to fill the void created between adjacent vertebral bodies, to provide mechanical stability, and to carry graft material. Failure of such implants can lead to significant morbidity. We discuss th...

To determine the effect of planned two-stage surgery using lateral lumbar interbody fusion (LLIF) on perioperative complication rate following corrective in patients with kyphoscoliosis. Consecutive degenerative scoliosis who underwent were divided into a control group that single-stage posterior-only and two-staged LLIF posterior fusion. We collected patient background surgical data assessed r...

Introduction: Intradural spinal cord tumors are uncommon with an incidence of 3 per 100,000 individuals. Multiple reports concerning intraspinal hematomas with neurologic deterioration following spinal needle insertion exist, but few reports have confirmed intraspinal hemorrhages from an undiagnosed lumbar ependymoma after attempted spinal anesthesia. Methods: A 22-year-old male with progressiv...

BACKGROUND Porous β-calcium pyrophosphate (β-CPP) was developed to improve the fusion success of posterolateral lumbar fusion (PLF). The possibility of accomplishing PLF using a mixture of porous β-CPP and iliac bone was studied. This paper reports the radiologic results of PLF using the β-CPP plus autograft for lumbar degenerative disease as a bone graft extender. METHODS A prospective, case...

Operative techniques for fusing an unstable portion of the lumbar spine or immobilizing a painful vertebral motion segment have been in use for many years. Lumbar fusion procedures initially were used to treat patients with infections (tuberculous spondylitis) or misaligned spines (isthmic spondylolisthesis) (1–8). Early techniques involving the use of harvested autogenous bone graft without in...

When ossification of the yellow ligament (OYL) occurs in the lumbar spine and extends to the lateral wall of the spinal canal, facetectomy is required to remove all of the ossified lesion and achieve decompression. Subsequent posterior fixation with interbody fusion will then be necessary to prevent postoperative progression of the ossification and intervertebral instability. The technique of l...
