Grappiolo G, Bruno CF, Loppini M, et al. - This study was attempted to explore clinical and radiological outcomes with a minimum 5-year follow-up in patients who underwent conversion of the fused hip to total hip arthroplasty. Researchers examined 57 patients (59 hips) to assess hip function and low back pain by using the Harris Hip Score, range of motion, and the Visual Analogue Scale. They also assessed subjective satisfaction with surgery and the presence of the Trendelenburg sign. They conducted Radiological assessment pre- and postoperatively to evaluate loosening and heterotopic ossification. At long-term follow-up, conversion of the fused hip to hip arthroplasty serves high levels of hip functionality and satisfaction with surgery. The results of this study indicate that an implant survival rate higher than 70% can be expected 25 years postoperatively.
