The purpose of this study is to evaluate the results of surgical treatment using the clavicle hook plate. Between June 2003 and July 2004, nine patients (eight men and one woman), with a mean age of 45 years (20 to 60) were treated using this plate. Six had distal claviclar fracture (Neer type II) and three had AC dislocation. The patients were evaluated after a mean follow up of eight months (4 to 12) using the Japan Orthopaedic Association shoulder score. As the plate was not removed in six patients, we evaluated pain, function, and range of motion. The average JOA score was 77.2 points (65 to 80). Clinical results were satisfactory, but the hook of the plate was found to have migrated to the acromion in all patients on X-ray.
