Combined Supracondylar Humerus Fracture, Monteggia Injury, and Radial/Ulnar Shaft Fractures in a 3-Year-Old Child

Ipsilateral pediatric elbow and forearm injuries are uncommon, particularly those comprising a supracondylar humerus fracture, radiocapitellar joint dislocation, proximal ulna fracture, and distal forearm fracture. We present the case of a boy who was 3 years, 6 months old and sustained this constellation of injuries. He underwent urgent treatment with closed reduction and percutaneous fixation of the humerus and flexible intramedullary nail fixation of the ulna. He presented with an ulnar sensory and motor neuropraxia that resolved, and he had full radiographic union and upper extremity range of motion by 3 months postoperatively.
