The aim of the study is to compare total hip arthroplasty intervention executed with or without the use of intraoperative fluoroscopy in terms of positioning of the hip prosthesis. The comparison will be made on post-operative follow-up X-ray performed as per clinical practice, in order to verify if intraoperative fluoroscopy provides better prosthesis components positioning or not.
