[Feasibility and limitations of reconstructive interventions in rheumatoid arthritis and Bekhterew's disease].

Among the reconstructive interventions in rheumatoid arthritis preponderate the arthroplasties, among them again the resection arthroplasties in contrast to the alloarthroplasties. The resection arthroplasties are most frequently performed on the forefoot and on the hand joint and the cubital joint. The artificial joint substitute is possible nearly on every joint. As to the hip joint the problems are already satisfactorily solved, not yet, however, on the knee joint. In Bechterew's disease the indication to the alloarthroplasty is to be rendered depending less on pain than on function. In severe kyphoses the columnotomy is to be taken into consideration.

Electrical stimulation of the callus formation by means of bipolar rectangular pulse sequences.

The clinical application of the electrical stimulation, lasting several weeks, for the callus formation is reported in 11 patients. Bipolar rectangular pulse sequences were used for the stimulation at a frequency of 1 Hz and a current intensity of +/-20mu amp. The electrical stimulation was successfully employed after distraction osteotomies with a KDA-apparatus in shortening of the leg provoked by different causes or in the treatment of pseudarthroses. The realignment of the newly formed callus and the osseous consolidation are stimulated and speeded up by the bipolar rectangular pulse sequences as it is also shown in the light of the roentgenograms of a case.

[The problem of infection in alloplastichip-replacement (author's transl)].

The total hip protheses implanted (THP) in two different operation periods (156 THP till September 174, 577 THP from October 1974 till December 1976) is evaluated under the aspect of infection and the influence on the rate of infection by different factors is emphasized. The rate of infection could be decreased from 7.1 per cent to 2.4 per cent adaquate measures.

[Experimental and clinical aspects of the living articular cartilage transplantation and half-joint transplantation (author's transl)].

The articular cartilage transplantation and the half-joint transplantation necessitate the assessment of specific biological-transplantation questions as to the structure and function of the hyaline cartilage. Compared with other organ transplantations biometric and biomechanical factors have to be taken into consideration additionally. Up to now contradictory results were obtained in the animal experiment. On principle a survival of grafted non-preserved parts of cartilage seems to be possible. In clinical practice therapeutic trials for autogenous reimplantation of articular cartilage, autogenous joint surface partial transplantations and half-joint transplantations are justified. Allogenous half-joint transplantations may also be possible in exceptional cases.
