H Bahadir Gokcen, Cagatay Ozturk
BACKGROUND: Achondroplasia, a genetic disorder of bone growth, produces specific clinical features of the extremities and spine. Spinal stenosis, seen in patients with achondroplasia, is a congenital disorder related to premature fusion of the pedicles to the lamina. It can be caused by ossification of the ligamentum flavum, which is rare in patients with achondroplasia. CASE PRESENTATION: We report a rare congenital spinal stenosis with ossification of the ligamentum flavum and thoracolumbar kyphosis deformity in a 24-year-old man with dwarfism and achondroplasia...

BACKGROUND: Healthcare costs comprise a substantial portion of total national expenditure. Although cost-effectiveness analysis in neurosurgery has recently become popular, there has been little cross-comparison of neurosurgical procedures. Our objective was to compare costs across elective neurosurgical procedures to understand whether drivers of cost differ. METHODS: The Value Driven Outcome (VDO) database was used to evaluate treatment costs for resection of vestibular schwannoma, intracranial meningioma, gliomas, and pituitary adenoma; anterior cervical discectomy and fusion (ACDF) and lumbar spinal fusion; and aneurysm treatment...

The anterior and middle columns instead of the posterior column of spine are usually destroyed by tuberculosis which could aggravate the kyphosis accompanying the growth imbalance of spine in children. The surgical method needs to be selected cautiously for effective treatment. To our knowledge, few studies have evaluated mid-term outcomes of 2 surgeries (posterior-only approach and combined posterior and anterior approaches) with allograft or shaped titanium mesh cages for the treatment of lumbar tuberculosis in children...

Background: Biportal endoscopic spine surgery (BESS) is a recent addition to minimally invasive spine surgery treatments. It boasts excellent magnification and fine discrimination of neural structures. Selective decompression with preservation of facet joints for structural stability is also feasible owing to access to the spinal canal and foramen deeper inside. This study has a purpose to investigate clinical benefits of BESS for spinal stenosis in comparison to the other common surgical treatments such as microscopic decompression-only (DO) and fusion and instrumentation (FI)...

RATIONALE: Degenerative spondylolisthesis is defined as forward slippage of a vertebra with respect to the underlying vertebra and is associated with the induction of lumbar canal stenosis. The use of anterior column support for degenerative lumbar conditions has been well documented. Direct lateral interbody fusion (DLIF) gains access via a lateral approach through the retroperitoneal fat and psoas muscle. It avoids many of the access-related complications yet comes with its own risks and limitations...

INTRODUCTION: Orthopaedic surgery can be a physically demanding occupation with high rates of fatigue and burnout. Fatigue has been shown to affect surgeon performance with higher rates of errors in fatigued surgeons. The metabolic cost of performing surgery has yet to be quantified. A better understanding of these costs may provide insights into surgeon fatigue and its effect on patient safety. METHODS: Eight subjects performed a one-level lumbar laminectomy and fusion on cadavers...

Background: Minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) has comparable fusion rates and outcomes to the open approach, though many surgeons avoid the technique due to an initial learning curve. No current studies have examined the learning curve of MI-TLIF with respect to fluoroscopy time and exposure. Our objective with this retrospective review was to therefore use a repeatable mathematical model to evaluate the learning curve of MI-TLIF with a focus on fluoroscopy time and exposure...

PURPOSE: Interleukin 6 (IL-6) and the acute phase C-reactive protein (CRP) blood concentrations after lumbar spine fusion may be affected by age. The purpose of this prospective observational study was to assess postoperative serum levels of pro-inflammatory IL-6 and CRP after instrumented lumbar spine fusion surgery. We hypothesized that older patients would have increased levels of IL-6 and CRP after surgery. METHODS: IL-6 and high-sensitive CRP biochemical marker levels were measured before instrumented spinal fusion, and postoperatively at 1 and 3 days, 6 weeks, and 3 months...
