Data collected prospectively from the Prospective Pediatric Scoliosis Study (PPSS) were analyzed statistically to address the hypothesis that covered specific aspects of treatment and its outcome. ⋯ There were no statistically significant baseline differences among the three instrumentation construct groups based on mean scores for the six SRS domains. None of the SRS domains had differences among the instrumentation constructs in change scores or significant differences among the instrumentation constructs.

Retrospective review. ⋯ Intraoperative chest wall violation produced detrimental pulmonary effects, as reflected by reduced percent-predicted values at 10-year follow-up. Posterior-only procedures, which spared the chest wall, showed significant improvements in FVC and FEV(1) absolute values without any change in percent-predicted values.

Retrospective review of 36 consecutive patients undergoing coronal plane deformity correction with intraoperative skull-femoral traction between 2005 and 2008 with motor evoked potential (MEP)/somatosensory evoked potential monitoring. ⋯ Intraoperative traction is associated with frequent changes in MEP monitoring. The thoracic location of the major curve, increasing Cobb angle, and rigidity of major curve are significant risk factors for changes in MEP with traction. The presence of any MEP recordings irrespective of its amplitude at closure was associated with normal neurological function. Somatosensory evoked potential monitoring did not correlate with the traction induced MEP amplitude changes.

Retrospective, controlled clinical study. ⋯ The use of an ECD significantly reduced the incidence of clinically relevant misplaced screws in a variety of scoliosis patients, thereby increasing the safety of pedicle screw implantation.

Case Reports Multicenter Study Comparative Study
Does bone morphogenetic protein increase the incidence of perioperative complications in spinal fusion? A comparison of 55,862 cases of spinal fusion with and without bone morphogenetic protein.
Retrospective review of a multi-institutional, multisurgeon database. ⋯ BMP use with anterior cervical fusion was associated with an increased incidence of complications. Use of BMP was not associated with more complications in thoracolumbar and posterior cervical fusions.
