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
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 retrospective review of all cases of high-grade spondylolisthesis treated by 1 surgeon between the years 1991 and 2003. ⋯ These data suggest that a posterior instrumented reduction and fusion of high-grade spondylolisthesis without decompression of the neural elements can be accomplished with acceptable radiographic and clinical results.

Comparative Study
Radiographic analysis of intervertebral separation with a 0 degrees and 30 degrees rope angle using the Saunders cervical traction device.
Radiographic analysis of cervical intervertebral separation, (IVS) while using the Saunders Cervical Traction Device (SCTD) (Chattanooga Corp., Chattanooga, TN) on a healthy population. ⋯ The research findings may have treatment implications when applying cervical traction with the SCTD. Further research using subjects with cervical nerve root compression will need to be conducted to substantiate clinical outcomes.
