Results of Conversion from Failed Austin-Moore Hemiarthroplasty to Cementless Total Hip Arthroplasty in Octogenarian Patients with Advanced Acetabular Erosion: A Minimum of 5 Years of Follow-Up

The direction of osteotomy over acetabular rim was done based on axis of prosthesis neck, and the width was the same as diameter of Austin-Moore prosthesis to dislocate the femoral head. Osteotomy over dome area should be avoided to prevent inadequate support of later acetabular shell implantation.
