Epidemiological total population study based on a prospective follow-up cerebral palsy (CP) registry. ⋯ The incidence of scoliosis increased with GMFCS level and age. Observed variations related to CP subtype were confounded by the GMFCS, reflecting the different distribution of GMFCS levels in the subtypes. Follow-up programs for early detection of scoliosis should be based on the child's GMFCS level and age.
-
Prospective trial of virtual endoscopy in spinal surgery. ⋯ Virtual endoscopy of the spine may be useful to surgeons for diagnosis, preoperative planning, and postoperative assessment by obviating the need to mentally construct a 3-dimensional picture of the spinal canal from 2-dimensional computed tomographic scans.
-
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.

Randomized Controlled Trial Multicenter Study
Grafton and local bone have comparable outcomes to iliac crest bone in instrumented single-level lumbar fusions.
Prospective multicenter randomized clinical trail. ⋯ At 2-year follow-up, subjects who were randomized to Grafton Matrix and local bone achieved an 86% overall fusion rate and improvements in clinical outcomes that were comparable with those in the ICBG group.
