Radioulnar synostosis in adults is a rare pathological fusion of the two forearm bones. When seen in adults, it is an uncommon complication after a minimally displaced ulnar fracture. We describe a 63-year-old man who presented with radioulnar synostosis after closed treatment of a left ulna midshaft fracture sustained 7 months earlier. At 10 weeks after presentation, the patient underwent radioulnar synostosis excision with nonsteroidal adjuvant therapy. At 18 months postoperatively, no pain was noted, with complete degree of flexion. Healthcare professionals should consider treating radioulnar synostosis with an operative excision in adults as initial management when forearm pronosupination is affected.
