Abstract

Disclosed is a bone plate comprising at least one screw that is to be fixed at a stable angle to at least one through-hole and at least one bone screw which is provided with an external thread in the top region. Said external thread tapers more in the screwing direction than a mating thread of the through-hole embodied as an internal thread such that the top of the bone screw is clamped in a stable direction in a torsion-proof manner when the bone screw is screwed in. The bone plate is configured elastically in at least one area adjoining the through-hole such that the material of the bone plate is not deformed in the ductile area because of the expansion resulting from the head of the bone screw being screwed in. As a consequence, the area surrounding the through-hole is not overstretched in any position of the bone screw along the entire length of the threads because of the interaction between the external thread of the top of the bone screw and the internal thread of the plate while the torsion-proof condition is maintained.
