Ossification of a ruptured achilles tendon: a case report in a diabetic patient.

Ossification of the Achilles tendon is a rare condition to be distinguished from the more frequently occurring tendon calcification. Achilles tendon ossification is more common in males and is usually associated with prior surgery or trauma to the tendon. A case history of a ruptured ossified Achilles tendon in an elderly diabetic female is presented. Although Achilles tendon rupture with subsequent ossification and fracture of the ossified Achilles tendon have been reported individually, there is evidence to suggest that this patient may have both ruptured and fractured an ossified Achilles tendon.
