ELONGATED PIN FOR AN EXTERNAL MODULAR FIXATION SYSTEM FOR TEMPORARY AND/OR PERMANENT FIXATION APPLICATIONS AND EXTERNAL MODULAR FIXATION SYSTEM

摘要

The invention relates to an elongated pin (2) for an external modular fixation system for temporary and/or permanent fixation applications to treat bone fractures and to connect two or more bone fragments to each other, comprising an elongated stem (3) extending along a longitudinal axis with a first end portion (4) and an opposite second end portion (5), said first end portion (4) having a tip for the insertion of the first end portion (4) into a bone, wherein said first end portion (4) has a conical shape with an external thread, forming a conical threaded end portion, the extension of said conical threaded end portion along the longitudinal axis being determined by the depth of penetration of the conical end portion limited to only the cortical portion of the bone.
