Follow-up study. ⋯ The results suggest that neither isometric neck muscle strength nor passive mobility of cervical spine has predictive value for later occurrences of neck pain in pain-free working-age women. Thus, screening healthy subjects for weaker neck muscle strength or decreased mobility of the cervical spine may not be recommended for preventive purposes.

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.

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.

This study is a research synthesis of the published literature evaluating the performance of magnetic resonance imaging (MRI) for differentiation of malignant from benign vertebral compression fractures (VCFs). ⋯ Several specific MRI features using signal intensity characteristics, morphological characteristics, quantitative techniques, and findings at other levels can be useful for distinguishing benign from malignant VCFs and can serve as inputs for a prediction model. Observer performance reliability has not been adequately assessed.

Multicenter Study Comparative Study
Culture and ethnicity influence outcomes of the Scoliosis Research Society Instrument in adolescent idiopathic scoliosis.
Retrospective comparative study. ⋯ Culture and ethnicity influence SRS-30 outcomes in AIS. Whites reported more pain than Japanese and Koreans. Japanese and Koreans had the lowest appearance scores. Koreans additionally were distinguished by the lowest activity, mental, and total scores. These cultural and ethnic differences must be taken into account when counseling patients with AIS and studying functional outcomes.
