Transverse ultrasound-guided fasciotomy in lateral epicondylitis.

Abstract

Lateral epicondylitis is a very common form of tendinosis that may heal spontaneously. Diagnosis is mainly clinical. Treatment is usually non-operative. However, if conservative treatment fails, open or arthroscopic tenotomy of the epicondylar muscles may be an option. Ultrasound-guided percutaneous tenotomy may now be performed on the common epicondylar tendon close to the enthesis, with a success rate close to that of conventional surgery. For several years now, we have used a slightly different technique, involving ultrasound-guided fasciotomy of the extensor digitorum communis and extensor carpi radialis brevis muscles at the radiohumeral joint. It may be performed under local anesthesia in the office. Ultrasound-guided hydro-dissection of the fascia is essential to facilitate the procedure and easily visualize the various anatomical structures. Fasciotomy can be performed with an ophthalmology scalpel, surgical knife or curved needle. This procedure is similar to arthroscopic techniques, but is significantly less expensive and with lower carbon footprint. It is safe and effective when a surgeon with experience in ultrasound-guided procedures performs it.
