Partial mid-portion Achilles tendon ruptures: new sonographic findings helpful for diagnosis.

Lorenzo Masci, Håkan Alfredson, Lars Öhberg


In all patients, the US examination showed a partial Achilles tendon rupture, presented as a disrupted dorsal (skin side) tendon line and an irregular tendon structure mainly located in the dorsal and mid-tendon. The size of the rupture varied from 1/3 to 2/3 of the tendon thickness. In the dorsal part of the tendon, corresponding to the region with disrupted tendon line and irregular structure, CD examination showed high blood flow—most often of a longitudinal character. Six of the patients were surgically treated, and macroscopical examination verified the US findings showing disruption on the dorsal side and a partial rupture in the dorsal and mid-tendon.
