Ipsilateral Distal Both Bone Forearm and Lateral Humeral Condyle Fractures With Posterolateral Elbow Dislocation: A Rare Injury in a Child

Lateral humeral condyle fractures are common in children, but concomitant elbow dislocation is rare. This case report involves a 10-year-old girl with an ipsilateral distal both-bone forearm fracture and a lateral humeral condyle fracture accompanied by a posterolateral elbow dislocation. Closed reduction of the elbow was performed in the emergency department without delay, and the patient was operated on as soon as possible. Closed reduction percutaneous pinning (CRPP) was performed for the distal radius fracture. The Weiss type III lateral humeral condyle fracture was reduced through a lateral approach, and fixation was performed using divergent pinning with two Kirschner wires. K-wires were removed, and the motion was initiated postoperatively in the fourth week. The patient obtained favorable postoperative results and regained full range of motion in both the elbow and wrist. Any complications, such as nonunion, malunion, cubitus varus, or avascular necrosis, were not observed.
