Lateral and anteroposterior radiographs of the left elbow joint showing posterolateral fracture dislocation with intra-articular entrapment of the avulsed medial epicondyle fragment. True lateral and anteroposterior radiographs could not be obtained due to the pain and the dislocation.

Anteroposterior and lateral radiographs of the left elbow were done that showed posterolateral dislocation of the left elbow joint with concomitant medial epicondyle avulsion fracture with intra-articular entrapment of that fragment (Figure 1).
Anteroposterior and lateral radiographs of the left elbow joint after closed reduction showing a displaced medial epicondyle avulsion fracture.

The CT scan showed a displaced medial epicondyle avulsion fracture but no other associated bony injuries (Figure 3).
Postoperative control X-rays showing good reduction and compression of the medial epicondyle fragment. To note, the patient has an above-the-elbow posterior cast splint.

The fragment was reduced with 1 K wire and fixed with 1 cannulated half-threaded 40 mm x 4.5 mm screw and a washer (Figure 4).
Left elbow control X-rays done at 3 weeks postop that showed proper integrity of the reduction.

Control X-rays were done at 3 weeks postop that showed proper integrity of the reduction (Figure 5).
Lateral and anteroposterior radiographs of the left elbow joint 12 weeks postop showing union of the avulsed medial epicondyle fragment. Anterior and lateral ossifications seen indicate possible partial ligamentous injury that calcified with time and were not seen on previous radiographs.

At 12 weeks postop, the patient had full range of motion of his elbow joint and adequate varus and valgus stability, and control X-rays done showed union of the avulsed medial epicondyle fragment (Figure 6).
