Ipsilateral Pediatric Supracondyar Humerus Fracture and Radial Head Dislocation

Abstract

Case: A 5-year-old boy presented with left elbow pain after a fall. Radiographs revealed a radial head dislocation without ulnar involvement which was treated with closed reduction in the emergency department. Two-week follow-up radiographs revealed a periosteal reaction along the medial epicondyle at the supracondylar region, consistent with a type 1 supracondylar humerus fracture. The elbow was treated with closed reduction and casting for 2 weeks. One year after injury, the patient had full painless range of motion. Conclusion: This case report highlights an injury pattern not previously described in the literature, and no previous recommendations exist regarding treatment. Although rare, radial head dislocation with simultaneous supracondylar humerus fracture can occur in pediatric patients. Our patient obtained a good result without surgical treatment.
