title: Palmar dislocation of the radio-carpal joint: a case report.
abstract: Radio-carpal joint dislocation, with or without fracture of the radius, is an uncommon injury; only 21 cases have previously been reported. Successful treatments of closed reduction and surgery have also been reported. A 35-year-old right-handed man was injured in a traffic accident and taken to an emergency room of a hospital, where radiographic examination showed a right palmar radio-carpal joint dislocation. Three days after injury, the patient was transferred to our department at Tokyo Medical University, Tokyo. We performed percutaneous pin fixation to maintain the position of his reduced radio-carpal joint. Two years postoperatively, radiographic examination showed a complete union of the avulsion fracture of the radius and a reduction of the joint. He had no marked disturbance in his daily activities apart from a slight pain while working. He had no limitation on the range of motion of the wrist joint and his grip strength was 41.6 kg. He returned to work 3 months after injury.
