Purpose/Objective:

This study aimed to evaluate clinical and radiological outcomes, risk factors and complications in patients undergoing surgical removal of heterotopic ossifications (HO) after total hip arthroplasty (THA). The role of radiotherapy was analyzed.

Material/Methods:

A retrospective study was conducted, including patients who underwent surgical removal of periprosthetic calcifications after THA surgery. Patient demographic characteristics, imaging, previous surgery, clinical scores, and surgical parameters were analysed. Radiotherapy and pharmacological prophylaxis (NSAIDs and COX-2 inhibitors) were evaluated. Multivariable logistic regression analysis was used to assess the association of the presence of HO with age, sex, and all those variables, which differed significantly (p<0.05) in univariate analyses.
