摘要： Methods and systems for installing an implant in an intramedullary canal are discussed. In an example, an intramedullary sounder tool has a sounder head including a plurality of teeth extending proximally from a distal tip towards a shank extending from the sounder head, each tooth comprising a distal cutting edge, a middle scraping edge, and a proximal cutting edge. The sounder head can be advanced into the intramedullary canal until the scraping edge engages cortical bone. If the scraping edge does not engage cortical bone, sounder tools having successively larger diameters can be advanced into the intramedullary canal until a scraping edge does engage the cortical wall, thereby avoiding cutting and damaging of the cortical bone. At such point, the width of the intramedullary canal and the implant used therein can be determined using markings on the shank that indicate the diameter of the sounder head.

摘要： An elbow prosthesis can include a humeral component having a yoke, an ulnar component having a head, a humeral bearing positionable in a base of the humeral component, an ulnar bearing assembly configured to engage with the head, and a pin extendable through the bearing assembly and the head. The pin can be extendable into first and second ears of the yoke to enable pivotable movement of the ulnar component relative to the humeral component. The elbow prosthesis can include a first fastener insertable through the first ear of the yoke and configured to engage with the pin, and a second fastener insertable through the second ear of the yoke and configured to engage with the pin.

摘要翻译： 讨论了用于在髓内管中安装植入物的方法和系统。 在一个示例中，髓内发声器工具具有发声器头，该发声器头包括从远端向近端延伸到从发声器头延伸的柄部的多个齿，每个齿包括远端切割边缘，中间刮削边缘和近侧切割边缘 。 发声器头可以进入髓内管，直到刮刃接合皮质骨。 如果刮除边缘不接合皮质骨，则具有相继较大直径的探测器可以推进到髓内管中，直到刮除边缘与皮质壁接合，从而避免皮质骨的切割和损伤。 在这一点上，髓内管和其中使用的植入物的宽度可以使用指示发音器头部的直径的柄上的标记来确定。
