Detection of positional brachial plexus injury by radial arterial line during spinal exposure before neuromonitoring confirmation: a retrospective case study.

To demonstrate the potential usefulness of radial arterial line monitoring in detection of brachial plexus injury in spinal surgery. Multiple neuromonitoring modalities including SEPs, MEPs and EMG were performed for a posterior thoracicolumbar surgery. Radial arterial line (A-line) was placed on the right wrist for arterial blood pressure monitoring.

Endoscopic instrumentation, correction, and fusion of idiopathic scoliosis.

Background Context: Endoscopic techniques have been used since 1993 to treat thoracic disk disease. Thorascopic techniques evolved into means of treating not only disk disease but also correcting thoracic spinal deformity with instrumentation and fusion.

Purpose: To evaluate the efficacy of endoscopic instrumentation, correction, and fusion of thoracic idiopathic scoliosis.

Anterior endoscopic correction of scoliosis.

Our technique of anterior endoscopic scoliosis correction demonstrates the ability to perform an anterior approach through a minimally invasive technique with minimal disruption of the local biology. The initial results appear to equal curve correction and fusion rates to those of a formal open anterior approach. Additional benefits are: 1) shortened operative time, 2) lower blood loss, 3) shortened rehabilitation time, 4) less pain, and 5) shortened hospital stays.

Thoracoscopic techniques for the treatment of scoliosis: early results in procedure development.

Objective: The goal of this study was to determine the effectiveness of an endoscopic option for anterior approaches to the thoracolumbar spine for scoliosis treatment. Fifty patients with 24 to 45 months of follow-up data were retrospectively studied. Techniques for endoscopic treatment of spinal disorders have been under development since 1993.

Frozen storage affects the compressive creep behavior of the porcine intervertebral disc.

Study Design: A biomechanical study of the compressive creep behavior of the porcine intervertebral disc before and after frozen storage.

Objective: To determine whether frozen storage alters the creep response, hydration, and nuclear swelling pressure of the intact intervertebral disc.

Summary Of Background Data: The mechanical response of the disc is dominated by swelling and fluid flow, whose effects are time-dependent.
