Complications of Elbow Trauma.

The elbow is a highly congruent trochoginglymoid joint allowing motion in both flexion-extension and pronosupination across 3 articulations. Therefore, treatment of fractures of the elbow can be technically challenging to manage, even after initial surgery. The posttraumatic elbow is prone to complications such as stiffness associated with heterotopic ossification, instability or subluxation (posterolateral rotatory instability and varus posteromedial instability patterns), and wound complications. This article discusses the pathoanatomy, prevention, and treatment of these complications.
