A study has been made of the wear of hip sockets of P.T.F.E. against various sizes of stainless steel femoral head in the course of total prosthetic replacement of the hip in the human subject. The most serious aspect of the failure of P.T.F.E. was the production of a tissue reaction by wear debris. Artificial hip joints using plastic sockets should, therefore, be designed to produce the minimum volume of wear debris over a given period. The smaller the diameter of the metal head the smaller… CONTINUE READING
