FIXIERUNGSSYSTEM FUER ROEHRENKNOCHENFRAKTUREN

摘要

A fixation system for tubular bone fractures (3, 4) consists of an elongated, flattened fixation element (20) and bone screws (10) connected to each other by means of a screw (11), a cone (16) and a conical segment section (15). The fixation element (20) has an essentially rectangular cross-section and is made of tissue-compatible, high-strength material, in particular implant steel. At least two holes in each of the two end sections (21) of the fixation element (20) extend through its opposing wide faces. The bone screws (10) are inserted through these holes. The fixation element (20) is made in one piece from the two relatively rigid end sections (21) and an intermediate connecting section between them, or from two superimposed parts connected to each other in the end sections. The connecting section (31) is elastic in comparison with the end sections (21), because its cross-section is smaller than that of the end sections (21). This compact fixation device can be implanted under the skin and eliminates transverse forces as well as flexing and torsional moments in the region of the fracture, without the implantation affecting the circulation. In addition, the normal forces in the fracture region can be adjusted as required.
