Tennis Elbow (Lateral Elbow Tendinosis)

Anatomy

The lateral epicondyle of the humerus, a bony prominence on the outside of the elbow, is the common site of attachment for most of the extensor muscles of the forearm Tennis elbow is a painful inflammation of the tendon on the lateral aspect of the elbow, caused by the pull of the muscles, which extend the wrist and fingers.

Mechanism of Injury

  • Strain from repeated, forceful wrist extension (eg. gripping tennis racquet during a shot), causing degeneration and inflammation of the associated tendons.

Symptoms

  • Pain is felt mainly at the lateral aspect of the elbow, it may also radiate upwards along the upper arm, or, more commonly downwards along the outside of the forearm.
  • Grip strength is affected, causing problems with carrying things. In some cases light tasks, such as picking up a glass of water, are enough to precipitate pain.
  • A distinct tender point is elicited by pressure or percussion over the lateral epicondyle or justdistal to it.
  • Pain occurs over the lateral epicondyle when with resisted wrist extension or third finger extension. These signs strongly suggest a diagnosis of ‘tennis elbow’.
