The aim of the study was to assess the efficacy of a cementless acetabular cup without bone grafting in a cohort of patients with protrusio acetabuli who were treated with total hip arthroplasty. We retrospectively reviewed the records of a cohort of 45 patients with protrusio acetabuli who received elective total hip replacements between 2009 and 2011 at Tygerberg Academic Hospital. We reviewed pre- and post-operative radiographs and the most recent follow-up radiographs (minimum of three months) to assess cup osteointegration. We classified protrusio acetabuli according to Sotelo-Garza and Charnley into mild, moderate and severe, by evaluating pre-operative radiographs.Purpose
