Abstract |
20-year-old right handed man was immediately brought to our clinics due to motor vehicle accident. Radiographic examination revealed dorsal dislocation of right radiocarpal joint associated with fracture of radial and ulnar styloid process. Arthroscopic findings after closed reduction is that palmar joint capsule and radiocarpal ligaments were extensively detached from the distal margin of the radius. Avulsed bony fragment of distal margin of radius was not seen. Articular surface of radius was intact except fracture of radial styloid. Percutaneous fixation was done under C-arm image intensifier. Sixteen months later, he had no wrist pain. Range of motion of right wrist was full. Grip strength was 107% of unaffected side. In follow-up radiographs, there were no evidence of osteoarthritic change of radiocarpal joint, neither evidence of intercarpal malalignment and instability. In the case of transstyloid radiocarpal dislocation, a radial part of radiocarpal ligaments remains intact, percutaneous fixation of styloid process fracture may be a treatment of choice. |
