Head and neck replacement prostheses in revision hip arthroplasty: experience with a single modern design

Orthopedics. 1999 Mar;22(3):313-8. doi: 10.3928/0147-7447-19990301-07.

Abstract

This study reviewed 52 revision hip arthroplasties in which calcar cortical deficiencies were addressed by implantation of a cemented, modern-design head and neck replacement femoral prosthesis. Mean clinical follow-up was 38 months. Radiographic follow-up beyond 22 months was available for 34 patients (mean: 35.8 months). Mean Mayo clinical hip score (maximum: 80) improved from 28.2 preoperatively to 55.2 at last follow-up. No femoral component was revised for aseptic loosening. However, radiographic analysis demonstrated 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 and excellent early survival.
