Abstract
This study reviewed 52 revision hip arthroplasties in which calcar cortical deficiencies were addressed by implantation of a cemented, modern-design h ead and neck replacement femoral prosthesis. Mean clinical follow-up was 38 months. Radiographic follow-up beyond 22 months was available for 34 patie nts (mean: 35.8 months). Mean Mayo clinical hip score (maximum: 80) improve d from 28.2 preoperatively to 55.2 at last follow-up. No femoral component was revised for aseptic loosening. However, radiographic analysis demonstra ted one prosthesis was probably loose and two were possibly loose. A 92.7% Kaplan-Meier 5-year implant survival rate free from radiographic loosening was projected. This type of prosthesis has yielded good clinical results an d excellent early survival.
