Ipsilateral supracondylar humerus fracture and Monteggia fracture–dislocation with distal radius physeal fracture in a pediatric patient: A case report

In pediatric patients, supracondylar humerus fractures concurrent with Monteggia fracture–dislocation and Monteggia fracture–dislocation concurrent with distal radius fracture are rare and have only been reported in case reports. We present the case of a 10-year-old girl with concurrent ipsilateral arm supracondylar humerus fracture with Monteggia fracture–dislocation and distal radius physeal fracture, which were treated with closed reduction and percutaneous pinning. The Monteggia fracture-dislocation was addressed with open reduction via a posterior approach and fixation using titanium elastic nails. The postoperative recovery was favorable. At 1-year postoperative follow-up, the Mayo Elbow Performance score was 100 points, and no limitations in joint range of motion were noted.
