[Static and dynamic studies on finger arthrodeses].

Some general techniques in arthrodesis of finger joints are described. Then biomechanical measurements were made after compression arthrodesis with screws, crossed KIRSCHNER wires, tension band wiring, compression plates (Swiss AO), and self compression plates, creascent shaped (MITTELMEIER). By screws, a maximal compression between 25 and 34 kp is achieved. Using a selfcompressing, bent, crescent shaped plate, one gets a compression of about 18 kp. This osteosynthesis resists a high deflection momentum if edgewise inserted.
