CASE: A five-year-old boy injured his right elbow. Radiography revealed an anterior dislocation of the elbow with an olecranon fracture and a proximal radioulnar joint dissociation. Computed tomography (CT) confirmed the disruption of the proximal radioulnar joint, and a diagnosis of anterior transverse divergent dislocation of the elbow was established. Open reduction and fixation of the ulna was performed with good clinical results. CONCLUSION: We document a rare type of anterior divergent dislocation of the elbow. It is important to use CT to evaluate a proximal radioulnar joint dissociation to determine the correct diagnosis to aid in surgical planning.
