    • The invention relates to an intramedullary nail used for treating fractures of the femur. It comprises a distal end, which is appointed for insertion into the marrow cavity channel, a proximal end, and a longitudinal axis. A first bore is located adjacent the proximal end and extends through the proximal end and transversely intersects the longitudinal axis, and serves to accommodate a femoral head screw. The center axis of the first bore forms an angle with the longitudinal axis that ranges from 110° to 150°. A second bore is located between the first bore and the proximal end and extends through the proximal end and transversely intersects the longitudinal axis, and serves to accommodate a hip pin. The second bore is at least partially shaped as an oblong hole or slot with a width B and a length L>B, and the length L of the oblong hole extends in the direction of the longitudinal axis.
    • 本发明涉及用于治疗股骨骨折的髓内钉。 其包括远端,其被指定用于插入骨髓腔通道,近端和纵向轴线。 第一孔位于邻近近端并且延伸穿过近端并且横向地与纵向轴线相交,并且用于容纳股骨头螺钉。 第一孔的中心轴线与纵向轴线形成一个角度,范围为110°至150°。 第二孔位于第一孔和近端之间并且延伸穿过近端并且横向地与纵轴相交,并且用于容纳臀针。 第二孔至少部分地形成为具有宽度B和长度L> B的长孔或槽,并且长孔的长度L沿纵轴方向延伸。
