Varus Deformity Following Lateral Humeral Condylar Fractures in Children

Abstract

Lateral humeral condylar fractures are quite common in children. This article shows that varus deformity is a common sequela following such injuries. Twenty-four patients were studied, with a mean follow-up of 4.8 years. A loss of carrying angle, seen in 10 cases, occurred with comparable frequency in undisplaced (50%) and displaced (39%) fractures. The deformity was usually mild, averaging 10 degrees in the undisplaced fractures and 9.6 degrees in the displaced fractures treated with open reduction. We conclude that varus deformity is common in this injury, and occurs whether or not the fracture is displaced.
