Adding a Transverse Scan in the Ultrasound Diagnosis of Extensor Tendinopathy
Walter R. Frontera, MD, PhD
Extensor tendinopathy ("tennis elbow") is a common term used to describe pathology of the forearm extensor tendons that converge to anchor the muscles to the lateral elbow. During traditional ultrasonography using the longitudinal scanning method,1 it is difficult to determine which component of the common extensor tendon (CET) is affected. We propose the addition of a transverse scan to better visualize the tendons that join and form the CET. The attached video illustrates findings from both longitudinal and transverse scanning methods.
