ABSTRACT
In 1982, We reported the reasearch of whole-ceramic artificial hip joint. In this paper, a method is established for implanting direction and fixation of ceramic artificial acetabulum. The fixation can be active mechanical fixation by using three directional conical screw instruments of acetabulum which have been invented and applied in clinical by us.This study presents a discouraging results.Of a total of 54 cadaver acetabulum 50 were successful and in all of 10 patients whole-ceramic acetabula had been implanted satisfactorily by using our instruments
ABSTRACT
This report covers the intensive experimental research regarding cadaver acetab-ulum with triphastic conical screw instruments.In order fully to familiarize with the functions of three directional conical screw instruments and carefully to tackle the problems of operation, whole-ceramic acetalulawere replaced in 33 cadaver acetabula. As a result, of all cases operated on, 29 were performed successfully
