Review Case Reports
Fat embolism syndrome following percutaneous vertebroplasty: a case report.
Vertebroplasty is commonly performed for management of pain associated with vertebral compression fractures. There have been two previous reports of fatal fat embolism following vertebroplasty. Here we describe a case of fat embolism syndrome following this procedure, and also provide fluoroscopic video evidence consistent with this occurrence. ⋯ Percutaneous vertebroplasty is a relatively safe and simple procedure, reducing pain and improving functional limitations in patients with vertebral fractures. This case demonstrates an uncommon yet serious complication of fat embolism syndrome. Clinicians must be aware of this complication when explaining the procedure to patients and provide prompt supportive care when it does occur.

Randomized Controlled Trial
Prevention of low back pain in the military cluster randomized trial: effects of brief psychosocial education on total and low back pain-related health care costs.
Effective strategies for preventing low back pain (LBP) have remained elusive, despite annual direct health care costs exceeding $85 billion dollars annually. In our recently completed Prevention of Low Back Pain in the Military (POLM) trial, a brief psychosocial education program (PSEP) that reduced fear and threat of LBP reduced the incidence of health care-seeking for LBP. ⋯ The results of this study will help to inform policy- and decision-making regarding the feasibility of implementing psychosocial education in military training environments across the services. It would be interesting to explore in future research whether cost savings from psychosocial education could be enhanced given a more individualized delivery method tailored to an individual's specific psychosocial risk factors.

The nerve root sedimentation sign in transverse magnetic resonance imaging has been shown to discriminate well between selected patients with and without lumbar spinal stenosis (LSS), but the performance of this new test, when used in a broader patient population, is not yet known. ⋯ In patients commonly treated with decompression surgery, the sedimentation sign does not appear to predict surgical outcome. In nonsurgically treated patients, a positive sign is associated with more limited improvement. In these cases, surgery might be effective, but this needs investigation in prospective randomized trials (Australian New Zealand Clinical Trial Registry, number ACTRN12610000567022).

Combined anteroposterior spinal fusion with instrumentation has been used for many years to treat adult thoracolumbar/lumbar scoliosis. This surgery remains a technical challenge to spine surgeons, and current literature reports high complication rates. ⋯ The new hybrid technique demonstrates good long-term results, with less morbidity and fewer complications than traditional anteroposterior surgery select patients with thoracolumbar/lumbar scoliosis. This study received no funding. No potential conflict of interest-associated bias existed.

Thoracic myelopathy caused by an anterior, massive ossified plaque is often progressive and responds poorly to conservative treatment. Direct removal of the compressing ossification is the optimal procedure for a spinal cord that is severely impinged anteriorly. However, both anterior and posterior decompressive manipulations have caused catastrophic iatrogenic spinal cord injuries. A comprehensive treatment method for severe thoracic myelopathy that enables a sufficient and safe decompression of the spinal cord is needed. ⋯ One-stage posterior decompression, anterior extirpation of the ossification, and interbody fusion with instrumentation via a modified posterior approach is a safe and effective treatment for severe thoracic myelopathy resulting from prominent anterior impingement. This procedure is technically demanding, and the indications are limited to thoracic myelopathy caused by severe anterior impingement of various etiologies from T4-T12.
