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.

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.

This is a retrospective single-center case study involving 115 obese and nonobese patients who underwent minimally invasive lumbar surgery between 2004 and 2007. ⋯ This is the first study comparing operative results from tubular microsurgery between obese and nonobese patients. No major differences were detected in outcome, operative and perioperative data including complication rates. With tubular microsurgery, obese patients experienced the same or equally beneficial outcome, compared to nonobese patients, while incision lengths, blood loss, operative times, and length of stay were less when compared to open procedures. Other comorbidities and age had no significant impact on perioperative complications and clinical outcome.

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.

A comparative analysis of paraspinal muscle damage and radiographic parameters after mini-open and conventional open posterior lumbar interbody fusion (PLIF). ⋯ Mini-open PLIF is safe and effective. Mini-open PLIF was less invasive than open PLIF with regard to the MF muscle.
