Divergent Elbow Dislocation Associated with Ipsilateral Fractures of Ulnar Diaphysis and Radial Styloid Process in Adult: A Case Report

INTRODUCTION: The divergent elbow dislocation represents a rare lesion where the proximal radioulnar joint is torn and the distal part of the humerus goes between the radius and the ulna, the forearm dislocates posteriorly. CASE REPORT: We report the case of a 37-year-old male patient who had a traumatic divergent dislocation of the left elbow, associated with ipsilateral fractures of the ulnar diaphysis and the radial styloid process. The elbow joint was reduced under general anesthesia with internal fixation of the ulnar diaphysis fracture and a pinning of the radial styloid fracture. At 3 years of follow-up, the fractures were consolidated and the elbow was stable with a satisfying mobility. CONCLUSION: The aim of our case report is to underline the diagnostic and therapeutic challenges of this complex lesion.
