[Physical flow studies of new surgical aspiration drains].

Mathematical and experimental results demonstrate that the customary Redon drain as well as the improved Neo-Redovac drain develop suction only over a short initial distance. The above mentioned innovation of three additional oval holes does not increase efficiency. The disadvantage of rapidly diminished suction is overcome in the "Ulmer Drain", in which equidistant openings of continually increasing aperture are aligned towards the drain end.

[Osteosyntheses].

"Osteosynthesis" or internal fixation is the term used for operative reduction of bone fragments. The aim of the procedure is to effect such stable fixation that the affected extremity may be moved freely. The paper gives a survey of the technical basis of and indications for modern methods of internal fixation.

[Compression osteosynthesis with soft-tissue damage (author's transl)].

The advisability of open reduction with internal fixation by means of compression plates, screws, or tension band is dependant upon the localization and type of fracture, the kind and extent of soft-tissue damage, and also the time factor. Fractures in the vicinity of joints and intra-articular fracture dislocations are practically absolute indications. Its application is less frequent when the metaphysis is involved, except in the case of the forearm. Caution is suggested in the presence of chronic soft-tissue damage subsequent to peripheral circulatory disorders.

[Experimental studies on the biomechanics of syndesmosis].

The amplitude of movement of the distal fibula was measured with the tibio-fibular syndesmosis intact, severed and transfixed after anatomical and insufficient reduction. Transfixation by means of a location screw inserted above the syndesmosis horizontally and at an angle of 30 degrees in the frontal plane proved to be optimal since the quality of movement is not altered while its amplitude is only minimally reduced. Malalignment with shortening leads to rotation outward.

[Incorporation of autologous spongiosa into compact substance of bones in relation to the vitality of transplanted cells].

Different types of autogenous cancellous grafts were inserted into both femora of 20 sheep subsequent to special preparation or lethal radiation. The results were indicative of the primary role of the amount of grafted cancellous substance rather than the vitality of the transplanted cells. As compared to the outstanding effectiveness of the muscle-periosteum-flap with its revascularizing ability the significance of the compact receptor bed is minimal. These facts enhance the importance of early formation of vessels and the quantity of the osseous fraction of the substance grafted.
