Single-rod versus dual-rod anterior instrumentation for idiopathic scoliosis: a biomechanical study.

Study Design: Anterior single- and dual-rod instrumented human and ovine thoracolumbar spines, with and without structural interbody support (SIS), were biomechanically tested and compared in flexion, lateral bending, and torsion.

Objective: To determine significant differences in global stiffness of the constructs in an attempt to clarify specific indications for each in the treatment of spinal deformities.

Summary Of Background Data: Single- and dual-rod anterior systems have been used without any consensus as to indications for one versus the other.

Chiari I malformation associated with syringomyelia and scoliosis: a twenty-year review of surgical and nonsurgical treatment in a pediatric population.

Study Design: Retrospective review of patients with Chiari I malformation with or without associated scoliosis.

Objectives: Determine the effect of decompression of Chiari I malformation with syringomyelia on stabilization or improvement of associated scoliosis.

Summary Of Background Data: Chiari malformations are often associated with spinal deformities, including scoliosis.

Histologic characterization of acute spinal cord injury treated with intravenous methylprednisolone.

Objective: Many substances have been investigated for attenuation of spinal cord injury after acute trauma; however, pharmacologically only steroid administration has shown clinical benefits. This study attempts to characterize local spinal cord histologic response to human dose equivalent (HDE) intravenous methylprednisolone (MP) administration in a rodent model of acute spinal cord injury.

Design: Forty-eight Sprague-Dawley rats were divided equally into control and experimental groups.
