Chronic lateral epicondylitis—new perspectives on injection strategies and ultrasound evaluation

Abstract

Lateral epicondylitis (LE) is a common disorder of the extensor origin at the lateral humeral epicondyle, first described by Runge in 1873. The annual incidence rate of LE is 1.0 per 100 workers. Clinically, the patient with LE often presents with a painful elbow, defined as pain on the lateral side of the elbow aggravated by direct palpation of the lateral epicondyle and during resisted dorsiflexion of the wrist.
