Fracture of ossified Achilles tendon.

Ruptures of Achilles tendon are quite common. We here report a case of fracture in an ossified mass of Achilles tendon in an 84-year-old male patient. The mass occurred 78 years following surgery for bilateral equinus deformities of his ankle. Clinically, he had a palpably definite gap in the ossified area of the Achilles tendon, which was confirmed by a roentgenogram and a magnetic resonance scan of his left ankle. He was treated conservatively in a plaster cast for 12 weeks. The overall functional result a year after his treatment was quite satisfactory.
