title: [Comparative studies on stability of titanium and V4A osteosynthesis screws].
abstract: Three years of clinical use and testing provided clear support to the advantages of the self-tapping titanium splithole screws. Although having rather flat heads these screws afford a fast grip with the screw driver blade. In addition to this, the pin offers good axial guidance and adhesion of the screw. The cylindrical design of the screw equator improves the fit of the screw in the chuck of the screw driver. The spherical shape of the lower half of the screw head increases the circular contact to the osteosynthesis plate, which is particularly favorable in the case of a minor angular error.
