Four patients with ossification of achilles tendon, three of whom had undergone local excision of the ossified mass are reported on.
Case 1 was a 16-year-old man who had hard swelling on the right heel for one year. Roentgenographic examination of the right foot revealed, in the region of the tendon, a 4-cm area of ossification which excised.
Case 2 was a 52-year-old man who had congenital club foot conservatively. Roentgenographic examination showed bone formation in the body which had been treated of the left tendon, and at its insertion into the right os calcis. The formation was operated on.
Case 3 was a 55-year-old man whose Achilles tendon was raptured while walking. Roentgenographic examination showed an ossified mass at this site, and a spur on the calcaneus. Open operation was performed, and tendon ruptures were seen in the proximal and distal end on the fragment. A tendon suture was necessary.
Case 4 was a 31-year-old man who had been seen twelve years previously, for pain and swelling on both heels. Roentgenograms showed bone formation at the tendon insertion into both os calsis. No operation was performed.
We also reviewed 65 cases which have been reported on including these four cases. Of the cases where ossification occurred in the body of the tendon, 87.5% had had previous surgery of trauma. While on the other hand, only 51.2% of the cases occurring elsewhere in the body had. Tendon rupture occurred at the distal end of the ossification in all the reviewed cases except in Case 3 above.
