Convergent dislocation of the elbow.
Proximal radioulnar translocation is an extremely rare injury. Only seven cases have been reported previously. The authors report the case of a 6-year-old girl whose translocation was undiagnosed for more than 2 weeks. Definitive treatment required open reduction and use of a radiocapitellar pin to stabilize the proximal radius. At the 2-year followup, the patient has no symptoms and has resumed full activity with nearly full range of motion. To ensure early diagnosis of rare types of elbow dislocations, it is important to recognize the lack of supination and disruption of the radiocapitellar relationship on radiographs.
