RESUMO
CASE: A 42-year-old man presented with distal radius fracture. We performed external fixation combined with Kirschner wiring, which was removed 6 weeks postoperatively. After the removal of the implants, the patient could not achieve any pronation-supination, and distal radioulnar synostosis became apparent during the follow-up. The patient underwent distal ulnar osteotomy, and 60° pronation and full supination were achieved. No complications were reported at the 32-month follow-up. CONCLUSION: This is a rare case of radioulnar synostosis after percutaneous fixation surgery for distal radius fracture. The modified Sauve-Kapandji procedure can help restore motion, together with other appropriate postoperative interventions, and provides early mobilization.
