PROBLEM TO BE SOLVED: To provide a bone anchoring nail which can be connected with an external stabilization rod or a rod-shaped element and inserted more quickly with a force smaller than a widely known device, while providing fixability as secure as screws. SOLUTION: A bone anchoring nail is provided with a threadless shaft (1') having a free end (2), a head (3') opposite to the free end having a substantially U-shaped recess (7) for accommodating a rod (12) or a rodlike element, a longitudinal bore (4) extending through the shaft and opening towards at least the head (3') or the free end (2), and a plurality of openings (5) extending through the wall face of the shaft and communicating to the bore (4). The bone anchoring nail enables a quick insertion and a secure fixation enhanced by the in-growth of blood vessels. COPYRIGHT: (C)2008,JPO&INPIT |
