A salvage procedure: Radial head excision in children and adolescents-short-to-midterm outcomes and overview of the literature.

Abstract

Purpose of the study was to report the outcomes after radial head excision in children and adolescents in addition with a review of the current literature. We report a series of five children and adolescents, who had undergone a post-traumatic radial head excision. Clinical outcomes were evaluated in terms of elbow/wrist range of motion, stability, deformity and discomforts or restrictions at two follow-up points. Radiographic changes were evaluated. Patient's age at time of the radial head excision averaged 14.6 (13-16) years. Mean time from the injury to the radial head excision was 3.6 (0-9) years. Follow-up I averaged 4.4 (1-8) years and follow-up II 8.5 (7-10) years. At follow-up I, patients showed an average elbow range of motion of 0-10-120° Ext/Flex and 90-0-80° Pro/Sup. Two patients reported discomfort or pain at the elbow. Four (80%) patients had a symptomatic wrist with pain or crepitation at the distal radio ulnar joint. In three (60%) of them, an ulna plus at the wrist was present. Two patients required ulna shortening and autograft stabilization of the interosseous membrane. At final follow-up, all patients reported full functioning with daily activities. Restrictions were present with sport activities. Functional results at the elbow joint might be improved and pain syndromes lessen due to the radial head excision. Problems at the wrist are likely secondary to the procedure. A critical analysis of other options should be performed ahead of the procedure and a careless application should be avoided by all means. IV.
