Abstract
Background: Unlike articular shear fractures of the distal radius, radiocarpal fracture-dislocations defined as complete dislocation of the lunate from its articular facet of the radius are relatively uncommon. The management principles of these fractures have not been defined and there is no consensus on approach to management of these injuries. The aim of this study is to review our series of radiocarpal fracture-dislocations and propose a radiographic classification to guide surgical management. Methods: This study is reported based on STROBE guidelines. A total of 12 patients underwent open reduction and internal fixation. All the fracture-dislocations were dorsal and satisfactory objective outcomes achieved were comparable to literature. Injury morphology-specific management approach was used based on the size of dorsal lip fragment and the volar teardrop fragment attached to the short radiolunate ligament assessed by preoperative CT scans. Results: All patients with known outcome (n = 10) went on to resume their prior occupation and hobbies that included high-demand activities and manual labour at mean follow-up of 27 weeks. Average wrist flexion was 43° and wrist extension was 41° while radial and ulnar deviation were 14° and 18° respectively. Average forearm pronation was 76° and supination was 64° at final follow-up. Conclusion: We describe four injury patterns of radiocarpal fracture-dislocations based on preoperative CT scans that guide fixation. We believe that early recognition of radiocarpal fracture-dislocations and appropriate management can yield satisfactory outcomes.
