en جراحی زانو Knee surgery Background: Management of acetabular bone defects, especially massive ones, is a challenging issue for surgeons during total hip arthroplasty (THA). Inadequate bone coverage can lead to weakness of acetabular component fixation and instability, and finally, failure of surgery. In recent decades, different techniques and methods have been reported in literature to manage these defects according to their size and location. However, the routine use of many of these new methods is impossible in the majority of patients because of existing financial limitations. The aim of the present study was to evaluate the clinical and radiographic outcomes of THA with acetabular defect reconstruction using shelf-autograft.
