Abstract

We report an isolated anterior dislocation of the radial head in a 23-year-old man after a fall on the outstretched arm. At the time of the injury, the patient's elbow was in a position of mild flexion and pronation which was suddenly further pronated as he fell down. The radial head was incarcerated by the lateral portion of brachialis muscle, and annular ligament was interposed between capitellum and radial head. Open reduction was performed. During 12 months follow-up, reduction of radial head was well maintained without a limitation of range of motion.
