Abstract

Total hip arthroplasty is a surgical procedure that adresses to people with severe hip disorder. The number of total hip replacements is growing year by year due to the good functional results obtained after this procedure, which include pain relief, improvement of walking and quality of life. With improvements in the techniques, materials and prostheses, hip arthroplasties are performed in the younger age patients, which leads to the demand for revision procedures. This procedure almost always comes across with acetabular bone defect. The main challenge for the surgeon during the revision hip arthroplasty is to achieve good implant stability. The purpose of this study is to assess the early clinical and radiological results after revision acetabular components using trabecular metal shells and augments. It was performed on 26 patients classified as Paprosky IIC and IIIA. The functional evaluation was performed perioperatively, at three and at six months after the surgery using radiographic evaluation and Harris Hip Score. No evidence of cup migration or periacetabular osteolysis was noted. With low rate of complications and with overall good level of satisfaction, we assume that modular TM acetabular components may provide good long-term solutions for reconstruction of acetabulum in revision hip arthroplasty.
