Background and Purpose. Displaced middle third clavicle fractures are traditionally treated non-operatively and heal with residual deformity. Few studies assessed treatment success by using patient-oriented outcomemeasures or objective muscle strength testing. The purpose of our study was to determine whether clavicle malunion affects functional results. Methods. Union was documented in 25 patients who were treated conservatively due to a displaced mid shaft clavicle fracture. Ten had significant malunion. Patients were examined at least 12 months following the fracture. Function was assessed by DASH and UCLA questionnaires. Clinical assessment included Range of Motion (ROM) measurement, manual and isokinetic muscle strength testing. Healthy shoulder served as a control. Results. Mean follow up time was 38 months. The mean DASH score was 9, mean UCLA score was 31.7. Range of motion was preserved—less than 6 ◦ side-to-side difference. Abduction strength reduction in the involved side amounted to 7%. No correlation was found between radiographic malunion and the functional results. Interpretation. Displaced healed middl
