The extensor carpi radialis longus muscle flap for anterior elbow coverage.

Abstract

A muscle group resection for treatment of malignant fibrous histiocytoma of the distal arm exposed a 15 cm length of radial nerve. The soft tissue defect and radial nerve were covered with an extensor carpi radialis longus muscle island flap. The proximal dominant vascular pedicle enabled extensive mobilization and transposition of this muscle to cover the defect while preserving normal elbow, radial nerve, and hand function. Because of its ease of elevation, extensive arc of rotation, and its expendability, the extensor carpi radialis longus muscle flap should be considered as an option for reconstruction of defects about the elbow joint.
