Combined Pediatric T-condylar Humeral Fracture and Monteggia Fracture-Dislocation in the Upper Extremity: A Case Report

Monteggia fractures are characterized by a fracture of the ulna associated with radial head dislocation. T-condylar fractures of the humerus are intra-articular injuries that disrupt the distal humeral epiphysis. This report describes a rare case of a pediatric patient with an ipsilateral T-condylar humeral fracture and a Monteggia fracture-dislocation. A 10-year-old girl presented with elbow pain and deformity after falling while playing basketball. No open wounds or neurological deficits were observed, and the radial artery was palpable. The radiograph revealed a pediatric T-condylar humeral fracture and a Bado classification type I Monteggia fracture-dislocation. Surgery was performed on the day of injury, and the ulnar shaft fracture was repaired with a titanium elastic nail. Subsequently, the humeral condyle was stabilized with Kirschner wire fixation. Bone union was confirmed at two months postoperatively, and the nails and wires were removed at six months postoperatively. Two years post-surgery, the patient had full elbow range of motion with no growth disturbances, deformities, or pain. This rare upper extremity fracture-dislocation case illustrates the need for prompt surgery and long-term follow-up to monitor growth and function.
