Treatment of a heterotrophic ossification fracture at the proximal Achilles tendon: a case report

다국어 초록 (Multilingual Abstract)

A heterotrophic ossification fracture ~80 mm in size was found in the proximal Achilles tendon area on a plain radiograph in a 71-year-old female patient who visited the hospital due to right calf pain after jogging. On surgical findings, the entire Achilles tendon substance was changed into heterotrophic ossification in the calcaneus ossification center, and a total defect was induced after excision. Flexor hallucis longus transfer surgery, commonly used among various Achilles tendon reconstruction methods, was performed, and 14 months after the operation, satisfactory results were obtained without hindrance to daily life. Although there have been several reports of Achilles tendon ossification, no domestic report has yet been confirmed for a case in which acute fracture was prominently identified and treated when the entire proximal Achilles tendon substance was ossified.
