Fracture of the ossified Achilles tendon.

The authors report a fracture of an ossified Achilles tendon in a 44-year-old male patient who was admitted to the hospital after a minor injury with pain on the posterior aspect of his left calf. Examination disclosed a fracture of the ossified Achilles tendon. Plain roentgenogram and MRI confirmed Achilles tendon ossification and fracture at the distal one-third of the tendon. Surgical treatment with excision of the ossified mass and reconstruction with an Achilles tendon flap was performed. After two years, the patient has quite good function, and MRI shows healing of the tendon.
