To report a case of bilateral secondary coxarthrosis in a patient with a history of pelvic irradiation for sarcoma botryoides.
The patient had surgery and radiation therapy for sarcoma botryoides when she was 18 months old. Left and right cementless total hip arthroplasties were performed at the age of 36 and 40 years, respectively. Harris hip scores improved from 28.4 to 93 on the left hip after 84 months of follow-up and from 29.5 to 91.3 on the right hip after 38 months of follow-up.
Cementless total hip arthroplasty may be considered for irradiated hips, if radiation damage in bone has been stable for a long period of time.
