文献摘要

    A rare case of isolated traumatic hamate dislocation combined with fracture of the hamate hook is reported. Plain X-rays revealed a volar dislocation of the hamate, but computed tomography was necessary to recognise the fracture of the hamate hook.The injury was successfully treated with open reduction and internal fixation with Kirschner wires. Five weeks after the operation the Kirschner wires were removed and rehabilitation was started. At five months follow-up, the patient had minimal pain and he had resumed working. However, his grip strength was 50% compared to the uninjured side. Cone-beam computed tomography, a novel imaging modality in hand surgery, was successfully used during follow-up. We conclude that computed tomography is essential in emergency preoperative planning in this type of uncommon injuries in order to diagnose concomitant bony lesions which can otherwise be overlooked. Alternative treatment options are discussed, and literature is reviewed.
