Abstract
Purpose
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.
Methods
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.
Results
Our cohort of had a median age of 63 years and had a female of male ratio of 4 to 1. The mean follow up was 11 months. We had 9 mild, 29 moderate and 7 severe protrusio cases. At follow-up all cups showed signs of osteointegration with no signs of loosening.
Conclusion
The use of a cementless, plasma coated, dual radius acetabular cup without bone grafting in primary THR in protrusio acetabuli provides good primary stability with satisfactory short term radiological outcome.
