Posterior Ulno-Humeral Dislocation with Radioulnar Shaft Fracture: Case Report and Literature Review

Background: The occurrence of radioulnar shaft fracture and elbow dislocation simultaneously is not a usual event, and it has only been reported in a few studies. This study aimed to report a case with posterior ulno-humeral joint dislocation and concomitant radioulnar shaft fracture. Furthermore, in a literature review, we summarized other studies that reported this kind of fracturedislocation and the treatment chosen in each study. Case Report: A 12-year-old boy was admitted to the emergency department due to high-energy trauma following a car accident while cycling. Open fracture of the left radioulnar shaft and posterior dislocation of the left elbow were detected. Conclusion: More studies are required to advance our knowledge about this kind of fracture-dislocation, especially its mechanism of injury. Subsequent examinations can help us design an efficient classification system and determine the best treatment option for radioulnar shaft fracture with elbow dislocation.
