Tennis Elbow - Lateral Epicondylitis

 

Lateral epicondylitis, commonly known as “tennis elbow,” is a painful condition involving the tendons that attach to the bone on the outside (lateral) part of the elbow. Tendons transmit a muscle’s force to the bone. The muscle involved in this condition, the extensor carpi radialis brevis, helps to straighten and stabilize the wrist (Figure 1).

With lateral epicondylitis, there is degeneration of the tendon’s attachment, weakening the anchor site and placing greater stress on the area. This can lead to pain associated with activities in which this muscle is active, such as lifting, gripping and/or grasping. Sports such as tennis are commonly associated with this, but the problem can occur with many different activities.
