The author reports a case of isolated traumatic volar dislocation of the ulnar head in the distal radioulnar joint. This fairly uncommon injury is seldom accurately diagnosed at first presentation because there is no distinct deformity at the wrist and extension-flexion is normal and painless. However pronation is always restricted and painful. A dislocation of this joint may be simple or complex and the treatment varies accordingly. Because the dislocation in this patient had occurred more than two months previously, surgical reduction failed and resection of the distal ulna using Darrach's procedure was performed.
