[Theoretical principles of cemented prostheses].

Today total hip replacement has become a routine procedure in older patients all over the world. A good result is to be expected only, if the device will meet the following requirements: adequate force transfer to the bone, adequate stiffness and elasticity, sufficient range of motion, biocompatibility of the material, low friction, low rate of wear, sufficient lubrication and a secure anchorage. Up to now, the weak point is the bone cement. Advancements in its composition and improved cement techniques will guarantee good function without pain during a long enough period of time.

[Indications, technic and dangers of intra-articular injection treatment of the knee].

The indication for knee injection depends on the drugs to be used and the illness to be treated. These are lot of degenerative and inflammatory joint pains which demand for monarticular treatment by corticosteroid crystal suspension, local anaesthetica, non-steroidal antiinflammatory substances or drugs for chemical synovectomy in PCP. The technique is quite easy as for the big volume and the broad entrance of the articular space when the knee is flexed. The demand of hygienic circumstances must content a handling which prevents infection by quite simple methods by local antiseptics for the skin and one-way instruments. With the seldom exception of haemarthros and osteochondral necrosis infection is the utmost danger of knee injection. The putride arthritis should be managed by early synovectomia and movement trauma in order to limit infection and prevent ankylosis. Nevertheless, in case of empyema half of the joints will not regain their pre-existent movement and nearly a quarter loses their natural function.

[Practice of medical disclosure: protection of the patient--protection of the physician].

In practice, the information given to the patient prior to surgical procedure has to be adjusted to the individual case - and this not only because it is required by law. Although all protective measures taken by the physician against his patient may be useful from the juridical point of view, they often turn out to be insufficient in case of legal action when the burden of proof regarding the information given to the patient lies on the physician. This is due to the fact that a lack of understanding can be conceded even to the most emancipated patient, despite his personal signature, because the psychical conditions under which such a conversation is held are difficult to assess. The conversation without witness, the substance of which is then discussed in the presence of the patient has proved to be at least as sufficient as any signed form. This procedure avoids to strain the relation between physician and patient with juridical problems, a situation which is not at all desired by the wellminded patient seeking for help as well as by the responsible physician.

[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.
