Cemented double cup arthroplasty of the hip: experimental design and clinical application

Abstract

From February 1980 to October 1981, we have performed double cup arthroplasty of the hip in 10 cases successfully. Here is a report of our experience in clinical application of the double cup we designed and fabricated. Test of wear and tear of several different kinds of material of artificial joint was made. We observed 100 specimens of human dry femur and 80 specimens of acetabulum and reviewed femoral radiographs of 20 normal adults. Important data were obtained on measuring the length and width of the femur and the acetabulum.
