Fractured lateral epicondyle with associated elbow dislocation.

Abstract

We describe a case series involving a very unusual injury in children, i.e. a Milch 1 fracture of the lateral condyle with an associated dislocation of the elbow. This fracture configuration is normally stable as the intact capitellotrochlear groove serves as a lateral buttress for the coronoid-olecranon ridge of the ulna. In this series, however, each patient had an associated dislocation. These injuries usually present as a clinical dislocation and if the elbow is manipulated before radiographic imaging, the fracture line can be difficult to see on the post-reduction films. We recommend that all patients with a dislocated elbow should have elbow stability assessed under general anaesthesia, because a missed lateral condylar injury can lead to abnormalities in carrying angle, epiphyseolysis or an unstable elbow.
