Uncemented total hip replacement.

Between Jan. 1, 1976 and Dec. 31, 1981, 257 patients (age range from 21 to 65 years) with osteoarthritis of one or both hips were treated with ceramic hip replacement (Mittelmeier type). The cause of the osteoarthritis was variable. Hip replacement was carried out for the following conditions: rheumatoid arthritis including ankylosing spondylitis, aseptic necrosis of femoral head including post-traumatic and idiopathic forms, osteoarthritis of unknown origin, osteoarthritis following dysplasia or subluxation of the hips and loosened cemented hip prosthesis. The operative technique is described. Full weight bearing is not permitted for 16 weeks postoperatively, but mobilization and isometric exercises begin 2 days after operation and isotonic exercises are introduced later. Complications included fracture of the femoral shaft during operation, fracture of the acetabulum, protrusion, dislocation and infection early after operation (within 16 weeks) and aseptic loosening and pulmonary embolism (after 16 weeks). The results with this new type of hip replacement are encouraging. Good results based on patient satisfaction were obtained in 79% and poor results in 13%.

[Brisement--indication and technic of execution on individual joints].

The author gives a short review of the history of the brisement forcé (forcible breaking) which initially has been indicated only for the knee joint. Then he discusses the techniques of mobilization used today, which are applied under anesthesia. The indications for brisement forcé are presented, and some special conditions are described which must be considered if the performance of a brisement is intended. The further part of the study treats the technical execution of the brisement at the individual joints and gives a critical analysis of the indications and the results and chances of such a brisement.

[Corrective osteotomies of the head of the tibia (indications, technique and results) (author's transl)].

The best indication for corrective osteotomy of the head of the tibia is unilateral osteoarthrosis of the knee joint in which the apical angle of the deformity lies in the head of the tibia or in the joint. Full-length radiographs of the leg are indispensable to determine the level of the osteotomy and the angle of correction required. The indications for high openwedge osteotomy of the tibial condyles and high osteotomy of the head of the tibia are discussed, and some of the technical details of the osteotomy and its fixation are described. Between 1970 and 1977, 139 corrective osteotomies of the head of the tibia were carried out in our clinic. Seventy nine adult patients with 100 operated knees were followed up approximately 3.5 years after operation. In 80% there was an improvement with regard to pain and walking distance when compared with the praeoperative state. The results depend on the kind of deformity (varus deformities generally show a better result) and the seriousness and duration of pre-existing osteoarthrosis and laxity of the ligaments.
