Sonographic Evaluation of the Extensor Carpi Ulnaris in Asymptomatic Tennis Players

Abstract

Sonographic evidence of ECU tendinosis, partial-thickness tearing, full-thickness tearing, and subluxation can be seen in long-term, asymptomatic, recreational tennis players, whereas tendon sheath effusions, tenosynovitis, and tendon dislocation are uncommon. Further research is warranted to determine the clinical significance of asymptomatic ECU tendon abnormalities among long-term tennis players at multiple skill levels.
