[Biomechanical studies of various forms of symphysis banding].

The banding operation with polydioxanone cord for pelvis stabilization after accidental symphysis rupture is altogether reliable. Nevertheless in some cases we saw later on non satisfying reduction results in the "pelvis-half-joints"--especially in intense dislocation of the iliosacral amphiarthrosis. For improving the stability we investigated the stiffness character of some different methods with four PDS cords varied by four and six drilling holes. By increasing number of holes and short intentions direction knotted cords the stability is growing by 25%.
