[Ossification of the Achilles tendon after surgery of talipes equinus in childhood and condition following Köhler II (author's transl)].

In a 48-year old man, ossification was seen in the right achilles tendon which was to be interpreted as due to surgical extension of tendon in childhood following operation of talipes equinus. Only few reports have been published in literature, but in these, the x-ray findings were largely identical, and in all cases except one, injuries of the tendon or operations had preceded the condition. Ossification is associated with mild complaints only. It presents a typical pattern of x-ray findings distinguishing it from tendon ossifications or calcifications of other origin.
