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 fracture-dislocation 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.
