    • A technique to manufacture small joint orthopedic implants includes the steps of taking standard radiographs of a pathologic joint and the corresponding non-pathologic joint. In order to provide an accurate frame of reference, a specialized marker is placed in the radiographic field. By inspection of the radiographs and by comparison with the marker, the dimensions of the cortical bone and the cancellous bone can be quickly and accurately determined. These dimensions can be used to manufacture a suitable implant and installation tool. Typically, the implant will include a stem from which a post projects. A radially extending collar is located at the intersection between the stem and the post. A mating head is attached to the post. The head closely approximates the size and shape of the natural head being replaced. The stem will be non-round in cross-section to prevent rotation of the stem in the bone. For many applications, the head will not be fixedly attached to the post, but will be rotatable about the longitudinal axis of the post. One or more spacers that fit about the stem also can be provided in order to adjust the distance that the head projects from the bone.
    • 制造小关节骨科植入物的技术包括采取病理关节的标准射线照相和相应的非病理关节的步骤。 为了提供准确的参考框架,在射线照相领域中放置专门的标记物。 通过检查放射照片并与标记物进行比较,可以快速准确地确定皮质骨和松质骨的尺寸。 这些尺寸可用于制造合适的植入物和安装工具。 通常,植入物将包括柱,其中桩从该茎突出。 径向延伸的套环位于杆和柱之间的交叉处。 配合头连接到柱上。 头部紧密接近被替换的自然头部的大小和形状。 茎部横截面为非圆形,以防止茎在骨骼中的转动。 对于许多应用来说,头部不会固定在柱上,而是能够围绕柱的纵向轴线旋转。 也可以设置一个或多个适合于茎的间隔物,以调节头部从骨头伸出的距离。
