名称及摘要

骨锚固件
本发明涉及锚固件,包括螺钉(12),具有柄(13)与骨线部以及头(14;140),以及,包括接收部分(1)用于连接螺旋到杆-形元件(40),螺以及接收部分彼此连接在 polyaxial 或单轴方式,以及柄(13)螺旋作为管状设计以及壁具有多个凹槽(18)。 这样可以骨螺旋熔合环绕骨物质,以及同时骨部分或椎骨可以定位相对于彼此以及固定。 而且,物质引入骨可以引入正好以期望站点。
Bone anchoring element
The invention relates to an anchoring element comprising a screw (12) having a shank (13) with a bone thread portion and a head (14; 140), and comprising a receiving part (1) for connecting the screw to a rod-shaped element (40), the screw and the receiving part being connected to one another in a polyaxial or monoaxial manner, and the shank (13) of the screw being of tubular design and its wall having a plurality of recesses (18). In this way it is possible for the bone screw to fuse with the surrounding bone substance, and at the same time bone portions or vertebrae can be positioned relative to one another and fixed. Moreover, a substance to be introduced into the bone can be introduced precisely at the desired site.
