Abstract
PURPOSE: To assess treatment outcomes of young patients with medial epicondylar fracture of the elbow using standard operative protocols. METHODS: 24 consecutive patients with medial humeral epicondylar fracture underwent surgery by one of the 3 methods: (1) 2 parallel Kirschner wires, (2) 2 parallel Kirschner wires plus a tension-band wire, and (3) a screw plus an anti-rotation Kirschner wire. Fractures displaced less than 5 mm were treated conservatively (casting for 3 weeks). Outcome was assessed clinically and radiologically. The Mayo Clinic Elbow Performance Index was measured. RESULTS: The 3 patients with undisplaced fractures had good radiological results and scores. One patient with a displaced fracture refused surgery and subsequently developed pseudarthrosis and cubitus valgus. All operatively treated patients had good scores, but 2 treated with 2 parallel Kirschner wires alone developed pseudarthrosis. Patients in this group needed longer rehabilitation to attain a functional range of movement than those in other groups (treated together with a tension-band wire or screw). CONCLUSION: Surgery is recommended for children with displaced medial epicondylar fractures of more than 5 mm. The use of a tension-band wire, instead of a screw, together with Kirschner wires is the preferred treatment for younger children.
