Ulnar Nerve Injury in Pediatric Midshaft Forearm Fractures: A Case Series.

Objectives: To describe a midshaft forearm fracture pattern that places the ulnar nerve at risk in the pediatric population and provide 7 clinical case examples describing the injury pattern and treatment methods.

Design: Retrospective observational case series, review of literature, cadaver dissection, and treatment recommendations.

Setting: Multi-institutional, Southeast United States.

Guidelines to decortication in posterolateral spine fusion.

Despite the development of innovative approaches and the general success that has been achieved with spinal fusion, the rate of nonunion in some studies has been reported as high as 35%. Decortication has been shown to promote the fusion process and provides not only a rich source of vascular supply from the underlying cancellous bone, but also access to pluripotent stem cells within the marrow. Although the blood supply to the lumbar spine has been described, little attention has been paid to relevant areas of the spine most affected by decortication during the posterolateral fusion process.
