We experienced 2 cases of ossification of the Achilles tendon, reportedly a rare condition in literature.
Case 1 was 50-year-old man who had ruptured ossifying Achilles tendons bilaterally, and underwent surgical procedure. Osseous masses were seen at the end of the ruptured proximal tendon and the peripheral tendon tissue had degeneratively changed. After excision of the osseous masses and resection of the degenerated tendon tissue, the tendons were repaired by the Kirshmeyer method for the left side and pull-out method for the right side. Histological appearances demonstrated osteogenic potential and degenerated tendon tissue. The paticnt is now asymptomatic and no reccurence of ossification is seen.
Case 2 was a 56-year-old woman who had no trauma and operation history. Roentgenograms showed ossous mass at the Achilles tendon. The condition was treated with anti-inflammatory agents and two steroid, injections. The patient is now free of symptons. But the osseous mass seen in the roentgenograms remains the same.
