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

## TL;DR

A 10-year-old girl suffered a rare combination of two upper arm fractures and required surgery, which led to a full recovery after two years.

## Contribution

This case report highlights a rare co-occurrence of T-condylar humeral and Monteggia fractures in a pediatric patient.

## Key findings

- The patient had a T-condylar humeral fracture and a Monteggia fracture-dislocation after a fall.
- Surgical repair with titanium nails and Kirschner wires led to successful bone union and full elbow function.
- Long-term follow-up showed no growth issues or deformities two years post-surgery.

## Abstract

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.
