    • An instrument for measuring an angle about a cavity axis defined by a cavity extending into a head of a bone is provided, the bone having been resected on a plane that is inclined relative to the cavity axis. The instrument includes a stem arranged to be inserted into the cavity, a plane finder and a scale. The plane finder is coupled to the stem and arranged to contact the resection surface as the stem is inserted into the cavity and to move relative to the stem until the plane finder lies in a plane parallel to the resection surface. Movement of the plane finder relative to the stem is indicative of the angle about the cavity axis between a radial position indicated by part of the stem and a line extending perpendicularly from the resection surface. The scale is configured such that movement of the plane finder relative to the stem is indicated by the position of a portion of the plane finder relative to the scale.
    • 提供了一种用于测量由延伸到骨头中的空腔限定的腔轴线的角度的仪器,所述骨已经在相对于腔轴线倾斜的平面上被切除。 仪器包括设置成插入空腔中的杆,平面取景器和刻度尺。 平面探测器联接到杆上并布置成当杆插入空腔中并且相对于杆移动时接触切除表面,直到平面取景器位于平行于切割表面的平面中。 平面探测器相对于杆的运动指示在由杆的一部分指示的径向位置与从切除表面垂直延伸的线之间的腔轴线的角度。 刻度尺被配置为使得平面图相对于杆的运动由平面图的一部分相对于刻度的位置指示。

    • An alignment system for aligning a reaming guide during insertion into a cavity of a bone is provided. The bone has a resected surface and the cavity defines a cavity axis. The system includes a reaming guide that includes an elongate stem portion having a stem axis, a neck portion extending from the stem portion at an incline with respect to the stem axis, and an alignment instrument. The alignment instrument includes a handle defining a handle axis, the handle being releasably couplable to the reaming guide such that the handle axis is in a predetermined relationship with the stem axis. The alignment instrument further comprises a plane finder slidably coupled to the handle, the plane finder comprising a surface defined by a plane that intersects the axis of the handle at an angle having a predetermined relationship with the angle at which a resection surface of the bone intersects the cavity axis.
    • 提供了一种用于在插入到骨的腔中时将扩孔引导件对准的对准系统。 骨头具有切除的表面,腔体限定腔体轴线。 该系统包括扩孔引导件,其包括具有杆轴的细长杆部分,从杆部分相对于杆轴线倾斜延伸的颈部部分和对准仪器。 对准仪器包括限定手柄轴线的手柄,手柄可释放地联接到扩孔引导件,使得手柄轴线与杆轴线成预定关系。 对准仪器还包括可滑动地联接到手柄的平面取景器,平面取景器包括由与手柄的轴线相交的平面限定的表面,该角度与骨的切除面相交的角度具有预定的关系 腔轴。
