title: The biological problems of total hip arthroplasty.
abstract: Biological phenomena are the principal agents in triggering hip prosthesis aseptic loosening. The authors report the results of "in vivo" and "in vitro" and Raman-laser experimental tests, which confirm the validity of the ceramic-ceramic combination in relation to the amount of wear and biocompatibility of friction materials.
