Subarachnoid pleural fistula (SPF) is a type of cerebrospinal fluid (CSF) fistula that can arise as a complication following transthoracic resection of intervertebral disc herniation in the thoracic spine. It is an abnormal communication between the subarachnoid and pleural space. Negative intrapleural pressure promotes CSF leak due to a suction effect into the pleural cavity, with little chance of spontaneous closure. ⋯ We report a case of a 72-year-old woman who underwent anterior thoracic surgery to treat thoracic myelopathy caused by an ossified intradural disc herniation. The postoperative period was complicated by a subarachnoidal pleural fistula. We describe our successful treatment of this using noninvasive positive pressure ventilation and lumbar CSF drainage and review other methods reported in the literature.

The aim of this study was to describe the associations among pain, disability and psychosocial factors preoperatively as well as 3 and 24 months later for patients who undergo first time discectomy and to analyse the predictive value of psychosocial factors on the outcome 24 months after surgery. ⋯ Having high expectations on the return to work after surgery was the strongest predictor for a favourable outcome. Therefore, low preoperative expectations on return to work convey an important prognostic signal.

Aim of this study was to investigate RANKL and osteoprotegerin plasma concentrations in patients affected by disc herniation, the most common epiphenomenon of disc degenerative diseases, and in a matched cohort of healthy subjects and whether the expression of these markers was associated to a polymorphism of the vitamin D receptor gene. ⋯ Whether vertebral bone changes precede or follow cartilage deterioration in intervertebral disc degeneration is not known. Our results suggest a reduced bone turnover rate, associated to a specific genetic background, in patients affected by lumbar disc herniation which could be one of the favoring factors for disc degeneration.

The purpose of this study was to validate the Oswestry Spinal Risk Index (OSRI) in an external population. The OSRI predicts survival in patients with metastatic spinal cord compression (MSCC). ⋯ Our study has found that the OSRI is a significant predictor of survival at levels similar to those of the original authors and is a useful and simple tool in aiding complex decision making in patients presenting with MSCC.

A retrospective radiographic study was carried out to analyze the effect of lumbar disc herniation on the kinetic motion of adjacent segments. ⋯ Although disc height, translational motion, and angular variation are significantly affected at the level of a disc herniation, no significant changes are apparent in adjacent segments. Our results indicate that herniated discs have no effect on range of motion at adjacent levels regardless of the degree of disc degeneration or the size of disc herniation, suggesting that the natural progression of disc degeneration and adjacent segment disease may be separate, unrelated processes within the lumbar spine.
