Retrospective review of prospectively collected data on the neuromonitoring changes recorded during a consecutive series of cord level 3-column posterior spinal osteotomies for the correction of rigid pediatric spinal deformities in children between 2005 and 2012. ⋯ Changes unresponsive to increasing blood pressure occurring during decompression and bone resection (type II) responded well to osteotomy closure. Unresponsive changes during osteotomy closure (type III) were treated successfully with opening the osteotomy, cage adjustment, and less correction.

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

Retrospective case control study. ⋯ Neuromuscular patients fused to the pelvis, children older than 11 years, and surgery duration greater than 6 hours were associated with positive cultures. Back acne is a preventable risk factor for P. acnes seeding. Intraoperative bacterial contamination indicates a need to consider the type of surgery and patient age to determine prophylactic antibiotics and other modalities to prevent infection.

Retrospective review. ⋯ Intraoperative skull-femoral traction can be a safe and effective method to assist correction of severe and rigid scoliosis. It facilitates surgical exposure and pedicle screw insertion. It obviates the need of an anterior release surgery and associated morbidity, thus reducing the hospital stay and costs. It provides a much simpler way to correct the sagittal and coronal imbalance, as well as the pelvic obliquity.

Multicenter Study Clinical Trial
Next generation of growth-sparing techniques: preliminary clinical results of a magnetically controlled growing rod in 14 patients with early-onset scoliosis.
Prospective nonrandomized study. ⋯ Preliminary results indicated MCGR was safe and provided adequate distraction similar to standard GR. DR achieved better initial curve correction and greater spinal height during distraction compared with SR. No major complications were observed during the follow-up.
