Impaction-fracture of the capitate and lunate: a case report

We report a 15-year-old girl who underwent a midcarpal fusion for undiagnosed impaction-fractures of the capitate, lunate, and triquetrum after a fall on her outstretched left hand in a dorsiflexed and radially deviated position. The joint was dis-impacted, and the height of the lunate was restored using a cortical bone graft. The damaged proximal capitate articular surface was decorticated to facilitate fusion, as was the lunotriquetral articulation. Kirschner wires were inserted along the coronal plane. At the one-year follow-up, the patient had achieved a satisfactory range of motion and fusion of the capitate-lunatetriquetral articulations.
