Aim:
In an experimental study the accuracy of ultrasound in the detection of lesions of the achilles tendon was examined.
Methods:
60 Achilles tendons were examined post mortem macroscopically, histologically and by means of ultrascan.
Results:
All macroscopical changes were found in the sonograms. Especially changes of the form proved to be good diagnostic patterns for degenerative lesions of the tendon. At a distance of 2 cm proximal to the calcaneus histological changes could be detected with an accuracy of 73.3%. At 4 and 6 cm to the calcaneus we found similar results.
Conclusion:
A differentiation of the histological diagnosis by means of the sonographic behaviour was not possible. As a reproducible, effective and inexpensive method ultrasound examination has proved very useful in the detection of degenerative lesions of the Achilles tendon.
