Posterior surgical approach to radius. Skin incision is made from lateral epicondyle to Lister tubercle. Tissue dissection is performed at level of midshaft, proximally through deep fascia between extensor carpi radialis brevis and extensor digitorum communis, with avoidance of injury to posterior interosseous nerve. Supinator and pronator teres are incised, and abductor pollicus longus and extensor pollicis brevis are not detached from origins.
