| Ultrasonography was performed prospectively in 16 patients with suspected rupture of Achilles tendon fromMarch to October 1992 to evaluale the diagnostic value of ultrasonography. Ultrasonography examinations were doneaccording to standary techniques, and then dynamic evaluations were performed during passive plantar flexion ofthe ankle. We reviewed 10 confirmed cases of ruptured tendons, among which 9 cases were confirmed by operation,and one by ultrasonography and MRI. ultrasonic results were compared with the findings at physical examination andsurgery. The normal thickness of the Achilles tendons in healthy sides on ultrasonography ranged from 3 to 5mm.The ruptured tendons were 6-10mm thick at 1-2cm superior to the upper margin of Os Calcis. Rupture sites onultrasonography were exactly predicted in 7 among the 9 operative cases. In on non-operative case, the rupturesite on ultrasonography corresponded to that seen on MRI. Tendon bucking on dynamic ultrasonography was positivein all 4 complete ruptures. In 2 of the 6 partial ruptures which were nearcomplete tears, tendon buckling was alsoobserved. In conclusion, ultrasonography is a valuable diagnostic modality in the diagnosis of Achilles tendonrupture, the differentiation between total and partial rupture, and in determining the rupture site. We considerultrasonography of tendon as an important diagnostic toot that may guide the treatment plan in the traumaticrupture of the Achilles tendon. |
