Rare complication of open reduction and internal fixation of fracture distal radius: A case report of distal radioulnar synostosis.

Case: A 57-years old man who sustained left distal radius fracture. We performed distal radius ORIF. At follow up visit, he could not achieve any supination-pronation movements. Radiographs showed radioulnar synostosis. Four months later, we performed excision of synostosis with interposition of fat graft in the left forearm. A year later, the patient showed good forearm pronation and supination.

Conclusion: This a rare case of radioulnar synostosis after ORIF distal radius fracture. Surgical intervention will help to improve the outcomes.
