Lateral epicondylitis (LE) is a degenerative disease process affecting 1% to 3% of the population between 40 and 45 years old. It was originally thought that the cause of lateral epicondylitis was an inflammatory process, which would then result in the symptoms. However, histological studies have demonstrated that, through repetitive microinjuries at the common extensor origin (CET) site, there is a degenerative process with gradual failure of repair in the extensor carpi radialis brevis (ECRB) tendon. Although it was originally described and associated with the act of playing tennis, the etiology of this pain in the lateral aspect of the elbow is more widespread and related to overuse of the CET though repetitive dorsiflexion and pronosupination exertion of the wrist. The initial diagnosis is by clinical suspicion. Imaging is further performed to help in evaluating disease extent, exclude other entities that cause lateral elbow pain, and for surgical planning. Various imaging modalities can be used to evaluate LE. Nowadays, additional imaging modalities are commonly needed to help complement a clinical diagnosis. Due to some limitation of x-ray and MRI, US, specifically with the application of elastography is gradually attracting public attention. Shear-wave elastography (SWE) measures the elastic properties of tissues, based on the well-established principle that shear waves propagates faster in healthy tendons than diseased ones so can be used in diagnosis of tendinopathy. This study aimed to review the different radiological assessment for lateral epicondylitis.
