[Sonography of the Achilles tendon and its bursa].

Pain and disturbed function in the sole of the foot leads to damage of the tendo Achilles and to abnormalities in its vicinity. They are frequent consequences of some sporting activities (jogging). Differentiation between bursitis, fat necrosis, degenerative changes in tendons and their rupture and from abnormalities of the ankle joint is important for treatment. In the symptomatic patients whom we examined, the bursa was involved in 72.9% and lesions of the tendo Achilles were found in 62.1%.
