[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.

[Fractures of the metacarpal bones II to V--conservative and surgical treatment].

Fractures of the metacarpals II-V can normally be handled conservatively. After reposition under local anaesthetic plaster of Paris is applied for a duration of 3 to 4 weeks. Open fractures usually with accompanying injuries, should be stabilized operatively. The functional results of conservative treatment are very good. Slight sidewards deviation of up to 1/3 of the width of the shaft and shortening of up to 6 mm don't interfere with good hand function. Palmar deviation of the distal fragment of up to 35 degrees following subcapitular fractures does not reduce hand function.

[Outcome after late reconstruction of dislocations of the acromioclavicular joint].

In a total of 130 cases with a complete luxation of the acromioclavicular joint (Tossy III) which were treated operatively, there are included 29 cases with older injuries (6 to 28 months after accident). Late reconstruction were regarded only such cases which needed a plastic reconstruction of the lig. coracoclaviculare. An account is given of the 21 cases, followed up on an average of 5,6 years after the operation. The material for the plastic reconstruction was autologous and heterologous tendons, fascia lata, carbon-fibres-ligaments, and especially lyodura. The results are very satisfied regarding to the mobility and stability of the shoulder joints. But there was seen a high rate of arthrosis of the a.c.-joint, which causes are discussed as well as the opportunity to make an osteotomy of the clavicula to degress the pressure at this point. The arthrosis is only painful in cases with a simultaneous instability.

[Arthrodesis and external fixation].

Though operative arthrodesis is less often indicated than before, in the knee and upper-ankle joints it is more successful than artificial joints. In cases of irreparable neuro-paralysis it is often the only alternative for the lower extremities. Today's external fixation and the standardization of its operative technique make good stability possible, thus improving preconditions for consolidation of the resected articular surfaces, above all for the knee and upper-ankle joints. On the basis of 158 arthrodeses performed over a period of 10 years indications, technique and success rate are described.

[The concept of rehabilitation in orthopedics].

The development of Orthopaedics from old homes of crippled children to modern university hospitals is shown in comparison of Berlin and Heidelberg. Founding those institutions, their tasks and aims surpassing medical healing became the important essential of rehabilitation, which nowadays includes many other specialities.
