    • An instrument for distracting the disc space between adjacent vertebrae and simultaneously preparing endplates of the vertebrae includes a body having opposing upper and lower surfaces separated by curved side surfaces that extend between a posterior end of the body and an anterior end of the body. A first plurality of teeth extends across the upper surface of the body, and a second plurality of teeth extends across the lower surface of the body. The first and second plurality of teeth may constructed as ratcheting teeth that angle back toward the anterior end of the body. Also a system for distracting the disc space between adjacent vertebrae and simultaneously preparing endplates of the vertebrae, includes at least two differently dimensioned instruments as set forth above.
    • 用于分散相邻椎骨之间的椎间盘间隙并同时准备椎骨的终板的仪器包括具有相对的上表面和下表面的主体,所述相对的上表面和下表面由弯曲的侧表面分开,所述弯曲侧表面在身体的后端和身体的前端之间延伸。 第一多个齿延伸穿过主体的上表面,并且第二多个齿延伸穿过主体的下表面。 第一和第二多个齿可以构造成朝向身体前端倾斜的棘轮齿。 还有一种用于分散相邻椎骨之间的椎间盘间隙并同时准备椎骨的终板的系统,包括如上所述的至少两个不同尺寸的器械。

    • An instrument is provided for use in shaping a femur preparatory to implantation of a knee prosthesis. A gap checking device is fixed to the distal end of the patient's femur and referenced to the epicondyles of the femur. The gap checking device includes slots through which a cutting instrument can be passed to shape the femur so that it can receive the femoral component of the prosthesis. One of the slots enables the distal femoral cut to be made. The thickness of the gap checking device is selected so that the distance between the distal femoral cut and the distal surface of the gap checking device plus the thickness of a shim resting on the cut proximal tibia surface is equal to the combined thickness of the tibial and femoral components of the prosthesis. This enables balancing of the ligaments to be checked before the femoral cuts are made, but while the gap checking device is secured to the femur.
    • 提供了一种用于塑造准备植入膝关节假体的股骨的器械。 间隙检查装置被固定到患者股骨的远端并参照股骨的上髁。 间隙检查装置包括槽,通过该槽可以切割器械通过以形成股骨,使得其可以接收假体的股骨部件。 其中一个槽使得能够制造远端股骨切口。 选择间隙检查装置的厚度,使得间隙检查装置的远端股骨切割和远端表面之间的距离加上搁置在切割的近侧胫骨表面上的垫片的厚度等于胫骨和 假体的股骨部件。 这使得能够在制造股骨切割之前平衡待检查的韧带,但是在间隙检查装置固定到股骨时。
