[Total hip prosthesis and sport (author's transl)].

The artificial replacement of the hip joint has become a routine operation the assessment of load resistance of the total hip prothesis (THP), on the other hand, is very variable. If at all possible, a THP should only be implanted in elderly people usually with the object of obtaining painless and improved walking ability. Occasionally, however, the question of the possibility of sports activities arises. But for this there are no practical pointers for better orientation. Therefore 120 operated patients under the age of 60 were questioned in detail on their sports activities and followed up. Then an attempt was made to classify the types of sport. Swimming, cycling, gymnastics, walking and rowing seemed suitable.

[Experiences with Wagner's cup prosthesis].

Surface replacement is an alternative procedure especially in younger patients who absolutely need hip replacement. Accurate diagnosis is imperative and the range of indications is naturally small. A follow up study of 44 patients (range, 10 months to 4 years) showed 2 loosenings (5%); other severe complications were not seen. In 39 (89%) hips was no more pain after operation and there was a distinct improvement of motility in 39 (89%) cases. Avascular necrosis should not be treated by surface replacement. Primary inflammatory diseases (rheumatoid arthritis) seem to have a higher incidence of complications, especially when long time treated with large doses of steroids. Cortisone medication promotes avascular necrosis of the hip and lytic enzymes coming from the pannus might be another reason for loosening. According to our experience the position of the cup according to varus or valgus has no influence on the result of the operation. The Watson-Jones approach seems to be better than the approach recommended by Wagner, because paraarticular calcifications are seldom seen.

[Results with ceramic-on-ceramic sliding endoprosthesis completely or partially fixed without cement].

41 patients with ceramic total hip arthroplasty were followed up (on an average 2.8 years p. op., mean age 49.7 years). 9 prostheses were of type Lindenhof, 32 were of type Mittelmeier. In 27 cases cementless implantation was performed, 7 cases were reimplants. Hip scores according to Merle d'Aubigne reached 41 to 18 in 11 cases, 12 to 14 in 12 cases, and less than 12 in 17 cases. In cementless total hip arthroplasty a major problem appears to be associated with the anchorage of the femoral stem. Using a screw type fixation of the acetabular component seems to guarantee good anchorage, this was found also for reimplants. Doubts are raised about the use of ceramic on ceramic combination in arthroplasty.
