Radioulnar Synostosis after Endomedullary Fixation of the Radius and Ulna in a Patient with Floating Elbow: A Case Report.

Floating elbow is a complex and rare entity caused by high-energy trauma. In this paper, we present the case of a patient who suffered a traffic accident with severe head trauma, floating elbow (humeral diaphyseal fracture, radial proximal diaphyseal fracture, and ulnar segmental fracture) and radial nerve injury. Fixations were made with a humeral plate and intramedullary rods in the forearm. Although the outcome was satisfactory, radioulnar synostosis was identified in postoperative controls. Due to the neurological compromise, type of fractures, and stabilization selected, we believe that the use of forearm intramedullary rods for similar cases should be carefully evaluated.
