Lateral epicondylitis or extensor tendinopathy: Lateral epicondylitis typically presents as lateral elbow pain arising from pathology (tendinosis) of the extensor carpi radialis brevis (ECRB) tendon, close to the extensor origin at the lateral epicondyle. As inflammation tends to be present only in the early stages of development, some prefer to refer to the condition as epicondylosis. As the site of pathology is usually below the lateral epicondyle in the ECRB tendon, and the primary pathology is collagen disorganization, it has also been called extensor tendinopathy (Whaley and Baker, 2004). Significantly, epicondylitis is a degenerative process rather than an inflammatory process (Whaley and Baker, 2004). With continued use and microdamage, partial tears of macroscopic size may appear (Regan et al., 1992).

Lateral epicondylitis (tennis elbow) is a common soft tissue lesion caused by damage to the extensor muscles of the wrist upon overuse (Chumbley et al., 2000). This disorder is characterized by pain and tenderness at the lateral epicondyle of the elbow. The extensor tendons of the wrist, especially the extensor carpi radialis brevis tendon, contract at the site of attachment to the humerus due to a series of specific sports activities such as tennis or repetitive occupations which cause stretching and as a result, pain, and inflammation (Kraushaar & Nirschl, 1999; Shiri & Viikari-Juntura, 2011).
