Hd. Clarke et al., Head and neck replacement prostheses in revision hip arthroplasty: Experience with a single modern design, ORTHOPEDICS, 22(3), 1999, pp. 313-318
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.
