A magnetic emergency release system for halo traction.

A magnetic emergency release system was developed for use in halo traction systems. Commercially available rare earth mounting magnets, with selected weight-carrying capacities, along with ferromagnetic receptacles, were used in line between halos and overhead pulleys to both carry the prescribed traction force and provide an emergency release in the event of excessive applied force due to a transportation accident and/or sudden application of full body weight when using overhead walkers equipped with traction systems. The magnet-receptacle pairs were calibrated with an in-line digital scale.

Structural bone allograft in pediatric foot surgery.

Structural bone allografts are used in a variety of surgical procedures, but only a few investigators have examined their use and associated complications in the pediatric population specifically. In a retrospective review of pediatric foot procedures, we sought to determine types and rates of complications associated with structural bone allografts as well as time to incorporation of these allografts. Minimum follow-up was 12 months.

Outcomes of gastrocnemius-soleus complex lengthening for isolated equinus contracture in children with cerebral palsy.

Background: The goal of the gastrocnemius-soleus complex (GSC) lengthenings in children with cerebral palsy (CP) is to achieve a plantigrade foot and normalize kinematics during gait. The study purpose was to evaluate the results of GSC lengthening for isolated equinus contracture in individuals with CP. It was hypothesized that GSC lengthenings would normalize passive ankle range of motion, kinematic, kinetic, and temporal spatial parameters.

Clinical applications of outcome tools in ambulatory children with cerebral palsy.

This article provides an overview of outcome tools commonly used to assess ambulatory children with cerebral palsy, research findings from a recent large multi-center study, and ways to integrate the research findings into clinical practice. The information presented in this article and in the referenced articles provides information on: outcome tools' discriminatory ability and responsiveness; readily available comparison data on 7 commonly used outcome tools that can be used at the point of care; prediction equations for the Parent report Pediatric Outcomes Data Collection Instrument (PODCI) by age and Gross Motor Function Classification System (GMFCS) level; and minimum clinically important difference thresholds by GMFCS level. This information can help clinicians select the best outcome tools to discriminate among severity levels and avoid ceiling effects.

Comparison of three heel cord surgeries in children with cerebral palsy.

This nonrandomized prospective descriptive study compared outcomes of three isolated heel cord surgeries in children with spastic diplegia cerebral palsy (CP): (1) heel cord advancement (HCA), (2) heel cord lengthening according to Vulpius (HCL-V), and (3) heel cord lengthening according to White (HCL-W). Thirty-two children were tested prior to and approximately 1 year after undergoing one of the three surgeries. Objective measures were collected for ankle passive and active range of motion, gross motor function measure (GMFM), and gait.
