Excerpt:
"Elbow dislocations are among the most commonly seen dislocations in the body, second in frequency only to dislocations of the shoulder and the fingers. The most common elbow dislocation is a posterior dislocation, which accounts for 90% of cases (Fig. 14–34).26,27 Anterior, medial, and lateral dislocations make up the remainder of the cases. Lateral and medial dislocations can occur in isolation, but are more often seen in combination with either posterior or anterior dislocations or with fractures. Anterior dislocation of the elbow is almost always associated with fractures.Posterior dislocations, in which the olecranon is displaced posteriorly in relation to the distal humerus, account for the majority of dislocations seen at the elbow (Fig. 14–34A).28 Elbow dislocations are classified as simple or complex, depending on whether there is a fracture in addition to the dislocation. Simple dislocations are more common than complex.The mechanism of injury is a fall on the extended and abducted arm. A combination of valgus, supination, and axial forces acts to tear ligamentous attachments..."
