Abstract

Possible complications of hip prosthesis implants include the appearance of heterotopic ossifications (HO), i.e., the neoformation of bone tissue in the periprosthetic areas: it occurs in the months following the intervention due to a structural transformation of parts of the gluteal muscle. Materials and Methods: In the period between October 2014 and November 2023, at the same hospital facility by the same orthopedic team, 715 hip arthroplasty implantation surgeries were performed, of which 366 patients with coxarthrosis in the absence of recent fractures of the proximal epiphysis of the femur. Results The average age at the date of hip arthroplasty implantation surgery is 70.9 years. Radiographic checks performed after at least 3 months were taken into account to study the occurrence of heterotopic ossifications. In conclusion, in the event of the onset of HO, bloodless, physiotherapeutic, medical, and possibly radiant, timely, and close follow-up treatments are necessary to avoid the aggravation of local conditions.
