Purpose of the study: Revision surgery for scoliosis in adults is a technical challenge. Indications include flat back, non-union, and syndromes adjacent to the instrumentation The purpose of this work was to evaluate the pertinence of the
Introduction. In daily clinical practice, progression of spinal fusion is typically monitored during clinical follow-up using conventional radiography and Computed Tomography scans. However, recent research has demonstrated the potential of implant load monitoring to assess posterolateral spinal fusion in an in-vivo sheep model. The question arises to whether such a strain sensing system could be used to monitor bone fusion following lumbar interbody fusion surgery, where the intervertebral space is supported by a cage. Therefore, the aim of this study was to test human cadaveric lumbar spines in two states: after a
Obesity is an increasing public health concern associated with increased perioperative complications and expense in lumbar spine fusions. While open and mini-open fusions such as
Study design. Prospective randomized study. Objective. Primary aim of this study was to compare clinical and radiological results of
The purpose of this study was to investigate the efficacy and fusion rates of a unilateral pedicle screw construct supplemented with a translaminar screw in
The purpose of the study was to determine the effectiveness of rhBMP-2 when applied to an absorbable collagen sponge for interbody fusion with allograft spacers. Seventy-seven consecutive patients requiring inter-body fusion with one hundred and eighteen levels were included in the study. In thirty-six patients cervical or lumbar interbody fusions were performed using allograft and rhBMP-2. In the remaing allograft was used with demineralised bone matrix. In patients undergoing anterior cervical decompression and fusion (ALIF) machined allograft spacers were supplemented with anterior locking plates. In those scheduled for anterior lumbar inter-body fusion (ALIF) or
Purpose: Circumferential arthrodesis of the lumbar spine is necessary in certain selected situations (lumbar stenosis with instability and preserved disc height or spondylolisthesis). Posterior lumbar interbody fusion (PLIF) raises the risk of significant bleeding and fibrosis around the roots as well as neurological complications.
Introduction Circumferential fusion is becoming increasingly popular and has been advocated by many authors to improve the fusion rates and clinical outcomes of the degenerative lumbosacral spine. Anterior lumbar interbody fusion (ALIF) with posterolateral fusion does provide direct access to the disc via a separate incision/ approach but has inherent neurovascular risks. Posterior lumbar interbody fusion (PLIF) with posterolateral fusion mandates bilateral exposure with significant retraction of neural elements with higher incidence of postoperative radiculitis. PLIF also reduces surface area for fusion and disrupts the posterior tension band. TLIF allows for a circumferential fusion through a single posterior incision with only slight retraction of the thecal sac and nerve roots, with much less morbidity and costs as compared to traditional PLIF and ALIF techniques. To our knowledge, there are no studies that report radiographic and clinical results of using recombinant human bone morphogenic protein (rhBMP-2) and allograft in a TLIF setting. The purpose of this study was to assess clinical &

The August 2013 Spine Roundup360 looks at: SPECT CT and facet joints; a difficult conversation: scoliosis and complications; time for a paradigm shift? complications under the microscope; minor trauma and cervical injury: a predictable phenomenon?; more costly all round: incentivising more complex operations?; minimally invasive surgery = minimal scarring; and symptomatic lumbar spine stenosis.
