Multicenter Study Comparative Study
Comparison of surgical treatment in Lenke 5C adolescent idiopathic scoliosis: anterior dual rod versus posterior pedicle fixation surgery: a comparison of two practices.
Multicenter analysis of 2 groups of patients surgically treated for Lenke 5C adolescent idiopathic scoliosis (AIS). ⋯ At a minimum of 2-year follow-up, adolescents with Lenke 5C curves demonstrated statistically significantly better curve correction, less loss of correction over time, and shorter hospital stays when treated with a posterior release with pedicle screw instrumented fusion compared with an anterior instrumented fusion with dual rods for similar patient populations.

An in vitro biomechanical study. ⋯ We have designed a new type of AAOJ for correcting atlantoaxial instability arising from C1 to C2 anterior decompression procedures. The unique aspect of this joint is that it restores, to a great extent, the C1-C2 axial rotation that is lost during current stabilization procedures.

A prospective validation study. ⋯ The BIS assessments can be regarded as being a valid disease-specific questionnaire that provides interpretable information regarding the impact of back end leg pain on well-defined physical, social and mental aspects, and on the quality of life.

Method guidelines for systematic reviews of trials of treatments for neck and back pain. ⋯ Citations of previous versions of the method guidelines in published scientific articles (1997: 254 citations; 2003: 209 citations, searched February 10, 2009) suggest that others may find these guidelines useful to plan, conduct, or evaluate systematic reviews in the field of spinal disorders.

Retrospective cross-sectional study. ⋯ With the recent rise of anterior cervical spine procedures in the United States, substantial variation in the delivery of surgical care exists along a number of demographic factors. A detailed investigation of variation in surgical decision-making algorithms among spine specialists, as well as a determination of differences among patient populations in attitudes toward surgery, may help elucidate the trends observed in this study.
