Randomized, controlled study in a laboratory setting. Blinded observations/assessment of study outcomes. ⋯ In this commonly used rabbit posterolateral fusion model, MASTERGRAFT PUTTY in an autograft extender mode produces clinically and radiographically similar results to autograft fusion alone.
-
Retrospective clinical data analysis. ⋯ Percutaneous insertion of cannulated pedicle screws in the thoracic and lumbar spine is an acceptable technique with a low complication rate in experienced hands. The overall rate of perforation is below the higher rates reported in the literature for the open technique. Complication rates including pedicle fracture were low.
-
An in vitro biomechanical study. ⋯ The results indicated that the varied atlas fracture patterns were due primarily to radial forces causing outward lateral expansion of its lateral masses. Anterior and posterior arch fracture locations are dependent, in part, upon the cross-sectional arch dimensions. Transverse ligament rupture or bony avulsion is likely associated with real-life atlantal burst fractures.
-
Population-based, retrospective cohort. ⋯ Radiating spinal pain is an important risk factor for future sickness benefit. Radiating spinal pain was not associated with the duration of sickness benefit. These findings were independent of the effects of pain duration at baseline. The results highlight the need for interventions to prevent the onset of work disability, especially for those with radiating pain.

Case Reports
Treatment of a thoracic dural-pleural fistula with a vascularized omental flap: a case report.
Case report. ⋯ Treatment of thoracic psuedomeningoceles and fistulas can be difficult due to the unique negative intrathoracic pressure environment that complicates closure using traditional methods. Alternative treatment options may be necessary when more traditional techniques fail. Our report highlights one such option, a vascularized omental flap, which was used to successfully treat the patient.
