BACKGROUND: The functional outcome of surgically treated dislocated fractures of the distal radius is limited and does not correlate with radiographic results. Additional carpal lesions are assumed to be the cause. This study has evaluated which carpal lesions are associated with dislocated fractures of the distal radius. MATERIAL AND METHODS: A total of 104 consecutive patients with dislocated fractures of the distal radius were included in the study. The injured wrist was examined by radiography, computed tomography (CT) and magnetic resonance imaging (MRI) to determine additional carpal lesions. RESULTS: Radiographically 51 of the 104 fractures presented as type A according to the AO classification, 10 as type B and 39 as type C. The CT scan detected that only 5 of the 51 type A fractures were exclusively metaphyseal fractures. All type A fractures were associated with ligamental lesions in MRI. CONCLUSIONS: The results of the study confirm the hypothesis that every dislocated fracture of the distal radius is a combined carpal trauma associated with additional osseous and/or ligamental lesions.
