“…Long-term increased wear of the polyethylene socket may, however, limit its life expectan~y.~-~ To cope with the problem of wear, Boutin9Jo has introduced a ceramic/ceramic combination for the socket and the ball head. The same path has been followed by Griss et al, [11][12][13] Mittelmeier,14J5 and Salzer et a1.,I6 striving to achieve a cementless anchorage of the ceramic socket in the acetabulum. Long-time clinical results will have to show whether the extremely rigid ceramic socket does not cause bone restoration in the acetabulum.…”

Investigations over the years have shown that the mirror-finished Al2O3 ceramic is a much more suitable frictional counterpart to ultrahigh molecular weight (UHMW) polyethylene than metal. Despite the extremely gread hardness difference between polyethylene and Al2O3 ceramic, a considerable lower wear rate is obtained for the polyethylene socked with this new low-friction material combination. The unexpectedly favorable tribological behavior of this ceramic material in contact with polyethylene may be attributed to the following factors: better values for corrosion resistance characteristics, wettability with liquids, surfact gloss, hardness, and scratch resistance of the ceramic material in comparison with those of the hitherto used metallic implant materials (AISI-316L steel or cast Co-Cr-Mo alloy). It appears that, by using this new combination of materials for the socket and the ball, it will be possible to prolong the service life of artificial hip joints considerably without having effecy any fundamental changes in the present design and implantation principle retaining the hitherto used anchorage shaft made of wrought Co-Ni-Cr-Mo-Ti alloy Protasul-10 of extremely high corrosion fatigue strength.

“…Initially the crystal tips of the microscopically uneven surface are broken. At the end of this material depended process a new type of friction is established which can be attributed to a newly formed surface [6]. It is of significant importance to know that this initial corpuscular wear has also to be expected under body fluid lubrication.…”

SummaryTwo types of dense A1,0, ceramics (99.6% purity, 96% purity) were tested in the following fields of interest. I ) Wear resistibility using a pin and disk method under distilled water and human synovial fluid. Both types showed minimal initial corpuscular wear.2) Biocompatibility of ceramic wear particles in mice and rats after injection by different ways. The crystal material is permanently deposited in macrophages, after transport via lymphpatic and blood vessels also in the RES without chronic inflammatory and progressive fibrotic response.3) Under moderate stress conditions ceramic plates are fixed firmly by new bone formation within 2-3 months according to tetracycline label studies of bone growth in rats. 4) A new ceramic total hip prosthesis with two different socket designs for cement free fixation in bone is proposed and used in sheep experiments. The results of a 4 month experiment is presented showing firm fixation of tbe prosthesis under full stress conditions.

In 6 dogs the hip joint was experimentally replaced using a ceramic stepped-stem prosthetic device implanted in the thigh bone. In six other dogs V4A steel stepped-stem prosthetic devices inserted in the arm bone was used for replacing shoulder joint. The six devices replacing the shoulder joint healed up without complications and proved to be mechanically stable. From six devices replacing the hip joint only one was successful; the remaining five implants did not heal up due to fractures of the stem, loosening in the thigh bone and osteomyelitis. We suggest that these different results are based not on the different material, but on the different conditions characteristic for each implantation sites. The devices implanted in the arm bone of the dog, corresponding to the conditions in man, were stressed mainly by pressure and pull. In such conditions the newly formed bone tissue anchoring in the steps on the stem stabilized the device. On the other hand, the biomechanical load on the hip joint replacing device in the dog is represented mainly by rotation at stress, for which the devices are not conceived. The stepped profile of the stem can not work; it twists in the thigh bone and remains unstable causing consequences such as fractures, osteomyelitis and loosening. For experimental testing of bone and joint replacing prosthetic devices of cementless anchoring systems replacing human hip joint and thigh bone we recommend the shoulder joint of the dog instead of hip joint, because of the comparable biomechanics.
