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...

STUDY DESIGN A single-center, retrospective patient review of clinical and radiological outcomes of microsurgical posterior lumbar interbody fusion and decompression, without posterior instrumentation, for the treatment of lateral recess stenosis. PURPOSE This study documented the clinical and radiological results of microsurgical posterior lumbar interbody fusion and decompression of the lat...

background : lumbar degenerative spondylolisthesis (lds) is a degenerative slippage of the lumbar vertebrae. we aimed to evaluate the surgical outcome of degenerative spondylolisthesis with neural decompression, pedicular screw fixation, reduction, and posterolateral fusion. methods : this before-after study was carried out on 45 patients (37 female and 8 male) with lds operated from august 200...

Spinal tuberculosis is still prevalent in some developing countries. The purpose of this study is to investigate the efficacy and safety of one-stage posterior debridement, autogenous bone grafting, and transpedicular screw fixation in treating monosegmental thoracic and lumbar tuberculosis in adults. 37 patients were retrospectively reviewed in this study. The data of images, operative time an...

Pedicle screws are the main type of instrumentation used in the lumbar spine via the posterior approach. The accuracy of their insertion is always a concern because the malposition of screws is associated with a potential risk of iatrogenic injury of any neurovascular structure they pass. Fortunately, spinal cord and cauda equina injuries are rare. This 18-year-old paraplegic woman presented mo...

The increasing adoption of minimally invasive techniques for spine surgery in recent years has led to significant advancements in instrumentation for lumbar interbody fusion. Percutaneous pedicle screw fixation is now a mature technology, but the role of expandable cages is still evolving. The capability to deliver a multiexpandable interbody cage with a large footprint through a narrow surgica...

Objective To compare posterior lumbar interbody fusion (PLIF) with transforaminal lumbar interbody fusion (TLIF) for spinal fusion in patients previously treated by discectomy. Methods This retrospective study evaluated pre- and postoperative neurological status via Japan Orthopaedic Association (JOA) score. Surgical outcome was based on recovery rate percentage (RR%). Adverse event data were r...

BACKGROUND Lumbar interbody fusion is a common treatment for a variety of spinal pathologies. It has been hypothesized that insufficient mechanical loading of the interbody graft can prevent proper fusion of the joint. The purpose of this study was to evaluate the mechanical stability and anterior column loading sharing characteristics of a posterior dynamic system compared to titanium rods in ...
