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.
-
Prospective cohort with concurrent controls. ⋯ The Vitronic 3D Body Scanner has sufficient accuracy, reliability, and validity to monitor torso asymmetry due to scoliosis. Scan-based measures differentiate between normal and pathological and between preoperative and postoperative body shape and show good correlation with measures of appearance and quality of life.

A retrospective cohort study. ⋯ In Switzerland, the acceptance of the guidelines for treating traumatic spinal cord injury with high-dose methylprednisolone has been extremely high in the past. The use of high-dose methylprednisolone has decreased to a much lower level in Switzerland after the publication of new guidelines, which is comparable to various other countries. Despite these changes, no differences in the neurological outcome were detected between the observed patient populations.
