Comparative Study
A population-based analysis of healthcare utilization of persons with back disorders: results from the Canadian Community Health Survey 2000-2001.
A retrospective, population-based analysis. ⋯ With increasing disability as indicated by the presence of pain and functional limitations, and the presence of depressive symptoms, the higher the utilization of physician and nonphysician resources, with the exception of chiropractic care, which appears to be used by those with less severe symptoms. Lower socioeconomic status was associated with significantly lower receipt of services for almost all healthcare providers.

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.

Randomized Controlled Trial Comparative Study
Allograft versus no graft with a posterior multisegmented hook system for the treatment of idiopathic scoliosis.
A prospective, randomized study. ⋯ Our results suggest that a PSF using newer-generation multisegmented hook-screw and rod systems can be successful with allograft and/or local bonegraft without the use of supplemental autogenous bone graft (from the iliac crest or ribs) in patients with AIS.

Comparative Study
A prospective study of de novo scoliosis in a community based cohort.
A 12-year prospective study of de novo scoliosis in a community based cohort. OBJECTIVE.: To investigate factors associated with development of de novo scoliosis. ⋯ Incidence of de novo scoliosis was predictable by assessing asymmetric disc degeneration in frontal radiograph. More than 20% decrease in unilateral disc height or more than 5 mm longer osteophyte on one side led to increased incidence of de novo scoliosis, which might also influence long-term results of spinal surgery.

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.
