Abstract
The elbow is a trochleoginglymoid joint which configuration makes the elbow a fairly constrained and one of the most congruous and stable joints of the body.
The normal range of motion of the elbow is approximately 0° of extension and 140° of flexion. A functional range of motion for activities of daily living has been described to be of 30–130°, and the functional arc of throwing ranges from 20° to 130°.
Although it is not a weight-bearing joint, it can be subjected to high loads when practicing racket or throwing sports or in gymnastics. As a consequence of these continued sport activities, elbow stability, due to static and dynamic constraints, can be compromised.
The elbow is the second most commonly dislocated major joint, and 15–35 % of elbow dislocations can have residual instability. Elbow dislocations represent 11–28 % of all elbow injuries, with an annual incidence of 6–8 cases per 100,000 people.
The symptoms of the instability in athletes can occur following a single traumatic event or may be due to repetitive stress leading to chronic laxity such as in a throwing athlete. The focus of this chapter will be on elbow instabilities connected to sport activities.
