Abstract: Provided is a bone fixation plate, which is based on a divergent, biplanar and segmental concept which consists in the use of self-stable screws with a divergent biplanar arrangement by segments, wherein each segment is composed by self-stable screws which diverge certain degrees to each other, ending thereby located on different fixation planes. Thus, the divergent biplanar fixation favors the stability in relation to torsional loads in locked systems, since unlike the fixation with cortical screws where the bone helps to support the loads by having an implant-bone contact, when self-stable screws are used the loads are transmitted in the interface between them and the implant, being very prone to “cutting out” and the fracture of the screws when these are located in only one fixation plane.
