    • A femoral-side hip-joint prosthetic device for use in hip-joint replacement. The device includes an elongate stem whose surface defines maximally spaced infero-medial and supero-lateral surface curves, and which is characterized by a surface rotation which carries the supero-lateral surface curve about 18.degree.-30.degree. forward with respect to the infero-medial surface curve, on progressing upward along the upper surface portion of the stem, with the device in operative position. The rotation of the stem surface produces a close approximation to the cavity formed in the proximal femur by removal of the cancellous bone in the natural cavity formed by a wall of densified calcellous bone. A 3.degree.-15.degree. proximal anteversion of the neck is adapted to place a hip-joint ball carried on the stem at a position closely approximating that of the head in the natural femur. In the method of the invention, the cavity which receives the prothesis stem is formed by a rasp/broach-type tool whose surface conforms closely to that of the stem.
    • 用于髋关节置换的股骨侧髋关节假体装置。 该装置包括细长的杆,其表面限定了最大间隔的内侧和外侧表面曲线,其特征在于表面旋转,该表面旋转将超过侧面曲线约18°-30°, 内表面曲线沿着杆的上表面部分向上延伸,同时该装置处于操作位置。 茎表面的旋转通过去除由密实的钙质骨壁形成的自然腔中的松质骨而产生近似于在股骨近端形成的空腔。 颈部的3°-15°近端前倾适于将携带在茎上的髋关节球放置在与天然股骨中的头部近似的位置处。 在本发明的方法中,接收假体柄的空腔由表面与杆的表面相一致的锉刀/拉刀式工具形成。

    • An improved tibial component is provided for a knee prosthesis, wherein the tibial component includes a pair of tibial tray members adapted to accommodate independent longitudinal shifting during patient function while retaining a secure and stable fixation with respect to patient bone. The two tibial tray members comprise medial and lateral members for supporting the medial and laternal condyles of a knee joint. These tray members are interconnected by a slide key arrangement which restrains the tibial tray members against relative movement in the anterior-posterior and medial-lateral directions, while permitting relative shifting in a longitudinal direction corresponding generally with a central axis of the patient's tibia. In the preferred form, the two tibial tray members cooperatively define a common anchoring post and include one or more antirotation fins for mechanically locking with patient bone. In addition, in the preferred form, the two tray members include appropriate bone ingrowth surfaces for secure noncemented attachment to patient bone.
    • 提供了一种用于膝关节假体的改进的胫骨部件,其中所述胫骨部件包括一对胫骨托构件,所述胫骨托构件适于在患者功能期间适应独立的纵向移位,同时保持相对于患者骨骼的牢固且稳定的固定。 两个胫骨托构件包括用于支撑膝关节的内侧和后侧髁的内侧和外侧构件。 这些托盘构件通过滑动键装置相互连接,该滑动键装置限制胫骨托构件抵抗前后和内侧方向上的相对运动,同时允许在大致与患者胫骨的中心轴线对应的纵向方向上进行相对移动。 在优选的形式中,两个胫骨托构件协作地限定一个共同的锚固柱,并且包括用于与患者骨骼机械锁定的一个或多个防旋转翼片。 此外,在优选形式中,两个托盘构件包括适当的骨向内生长表面,用于牢固地非接合地附接到患者骨骼。
