Currently, there are over 300,000 lumbar discectomies performed in the US annually without an objective standard for patient selection. A prospective clinical outcome study of 200 cases with 5-year follow-up was used to develop and validate an MRI-based classification scheme to eliminate as much ambiguity as possible. 100 consecutive lumbar microdiscectomies were performed between 1992 and 1995 based on the criteria for "substantial" herniation on MRI. This series was used to develop the MSU Classification as an objective measure of lumbar disc herniation on MRI to define "substantial". ⋯ The most frequent types of herniation selected for surgery in each series were types 2-B and 2-AB, suggesting the combined importance of both size and location. The MSU Classification is a simple and reliable method to objectively measure herniated lumbar disc. When used in correlation with appropriate clinical findings, the MSU Classification can provide objective criteria for surgery that may lead to a higher percentage of good to excellent outcomes.

Since the rarefaction of neurosyphilis, axial neuroarthropathy is mostly secondary to spinal cord pathologies. Peripheral manifestations of neuroarthropathy resulting from Guillain-Barré syndrome have already been reported but to our knowledge, this is the first case of a patient diagnosed with axial involvement. After the acute phase, a 47-year-old woman suffered of paraparesia with a partial loss of sensibility under the tenth thoracic vertebra. ⋯ Natural evolution of Charcot spine remains unknown. Surgical treatment is recommended but even with circumferential fusion, failures do frequently occur. This observation allows us to report an original case and to discuss the etiology of axial neuroarthropathy, the classical radiographic findings, and the inherent difficulties of its treatment.

Review Meta Analysis
Transforaminal endoscopic surgery for lumbar stenosis: a systematic review.
Transforaminal endoscopic techniques have become increasingly popular in surgery of patients with lumbar stenosis. The literature has not yet been systematically reviewed. A comprehensive systematic literature review up to November 2009 to assess the effectiveness of transforaminal endoscopic surgery in patients with symptomatic lumbar stenosis was made. ⋯ The reported re-operation rate varied from 0 to 20%. At present, there is no valid evidence from randomized controlled trials on the effectiveness of transforaminal endoscopic surgery for lumbar stenosis. Randomized controlled trials comparing transforaminal endoscopic surgery with other surgical techniques are direly needed.

Surgical site infection (SSI) following spinal surgery is a frequent complication and results in higher morbidity, mortality and healthcare costs. Patients undergoing surgery for spinal deformity (scoliosis/kyphosis) have longer surgeries, involving more spinal levels and larger blood losses than typical spinal procedures. Previous research has identified risk factors for SSI in spinal surgery, but few studies have looked at adult deformity surgeries. ⋯ As well, a history of prior SSI was also found to be a risk factor for SSI (P = 0.041). Patient obesity and history of prior SSI lead to increased risk of infection. Since obesity was related to an increased risk of both superficial and deep SSI, counseling and treatment for obesity should be considered before elective deformity surgery.

Multicenter Study Clinical Trial
Bioceramic vertebral augmentation with a calcium sulphate/hydroxyapatite composite (Cerament SpineSupport): in vertebral compression fractures due to osteoporosis.
A prospective, non-randomized multicenter study was initiated to study efficacy and safety of a partly resorbable composite of calcium sulphate and hydroxyapatite (Cerament SpineSupport), a novel, injectable bioceramic, in osteoporotic patients with vertebral compression fractures during 18-month follow-up. Fifteen patients with low-energy trauma and 1-2 vertebral compression fractures verified by magnetic resonance imaging were recruited to undergo percutaneous bioceramic vertebral augmentation under fluoroscopy. The patients were treated with a highly flowable bioceramic containing calcium sulphate, hydroxyapatite and the non-ionic radiocontrast agent iohexol, with final setting time within 1 h. ⋯ There was a statistically significant improvement of physical components in the QoL assessment. No extra-vertebral leakage or neurological deficits were reported in this series. This first prospective multicenter study on a partly resorbable bioceramic material indicate that fracture healing can be achieved with sustained pain relief over a follow-up period of 18 months in an osteoporotic patient population with vertebral compression fractures.
