Anterior elbow release for post-traumatic flexion contractures in patients 21 years or younger

Abstract

An elbow contracture in a young person can be a devastating problem. Significant contractures will lead to functional loss of the extremity. Appropriately performed contracture release can have profound implications on the overall well-being of the patient. The purpose of this study was to report improvements in sagittal-plane range of motion and the complication rate following an anterior elbow release for flexion contractures in patients 21 years or younger. We performed a retrospectivereview of 27 patients with a median age of 16.8 years who were treated surgically for elbow flexion contracture with an anterior approach. Follow-up was possible in 18 of these patients at an average of 31 months. An anterior approach was performed in all 18 patients, with 4 patients undergoing an additional posterior incision to address posterior structures limiting extension. Elbow extension improved by an average of 35°, from -54° to -19°. The mean total arc of elbow motion improved by 37°, from 65° to 102°. Two complications occurred: traction-related neurapraxia of the lateral antebrachial cutaneous nerve and transient neurapraxia of the posterior interosseous nerve. Elbow contracture release through an anterior approach is an acceptable surgical option. Significant improvement is obtained with a low risk of complications.
