Review Meta Analysis
School-based interventions for spinal pain: a systematic review.
Systematic review. ⋯ The poor quality of the reviewed studies limits the conclusions that can be made regarding the effectiveness of school-based spinal health interventions.

Comparative Study
Fluoroscopically assisted surgical treatments of spinal disorders: conceptus radiation doses and risks.
A series of anterior-posterior and lateral fluoroscopic exposures at 5 spinal levels were performed on anthropomorphic phantoms simulating the 3 trimesters of gestation. ⋯ Individual dose assessment is paramount in every pregnancy. Variations in fluoroscopy practices and gestational stage significantly affect fetal doses.

Comparative Study
An evaluation of image-guided technologies in the placement of percutaneous iliosacral screws.
A surgical simulation study in human cadaver spine specimens was conducted to evaluate the accuracy of 3 different surgical navigation systems compared to standard fluoroscopy in the percutaneous placement of iliosacral screws. ⋯ Computer-assisted fluoroscopy based image navigation appears to be more accurate than standard fluoroscopy in placing these screws. However, errors may occur with all techniques. Further refinement in registration procedures may highly improve the accuracy of percutaneous screw placement in a variety of spinopelvic procedures.

Comparative Study
Intradiscal thermal therapy does not stimulate biologic remodeling in an in vivo sheep model.
Thermal energy was delivered in vivo to ovine cervical discs and the postheating response was monitored over time. ⋯ While a high temperature thermal protocol had a detrimental effect on the disc, the effects of low temperature treatment were relatively minor. Thermal therapy did not stimulate significant biologic remodeling. Future studies should focus on the effects of low-dose therapy on tissue innervation and pro-inflammatory factor production.

A C1-C2 operation by the transoral approach was simulated to study the anatomic stratification, various structures, and adjacent relationships. The anatomic parameters in relation to transoral atlantoaxial reduction plate (TARP) internal fixation were measured. ⋯ An atlantoaxial surgery through transoral approach is safe and feasible. This approach is suitable for an anterior TARP internal fixation, and the design of the internal fixation system should be based on the above anatomic data.
