    摘要： Methods for impaction grafting an intramedullary canal of a bone including a first canal portion and a second canal portion spaced along a canal axis. A first tamp may be moved axially within the canal to impaction graft the first canal portion. A second tamp may be mounted to the first tamp in axial sliding relationship and moved axially within the canal relative to the first tamp to impaction graft the second canal portion. The first and second tamps may be locked together in fixed axial relationship to prevent relative axial movement between the first tamp and the second tamp while the first tamp is moved to impaction graft the first canal portion before impaction grafting the first canal portion. The first and second tamps may be unlocked to permit relative axial sliding of the first and second tamps before impaction grafting the second canal portion.

    摘要： A method and apparatus for mixing bone cement which produces bone cement essentially free of entrained air. The apparatus includes a cartridge having two telescoping cylinders. The outer cylinder receives a cap thereon which hermetically seals the cartridge. The cap includes an outlet port in which a break-away agitator is installed and a port for connection of a vacuum pump. In use, a desired vacuum pressure is drawn on the cartridge and the inner cylinder is allowed to be drawn into the outer cylinder while the vacuum is being drawn, whereupon the inner cylinder automatically stops moving relative to the outer cylinder when the desired vacuum pressure is reached. Mixing of the bone cement is then performed under the partial vacuum thereby created. The agitator paddles provide a scraping action against both inner cylinder walls of the telescoping cylinders thereby improving mixing. After mixing, the agitator is broken away, an appropriate nozzle is attached to the cartridge and the cartridge is inserted into a cement gun. The leading portion of the bone cement develops a convex profile when axially advanced through the cartridge and the piston plug includes a tapered protrusion which generally corresponds to the profile of the bone cement. The cap and paddles are also shaped correspondingly to the convex profile developed by the bone cement, resulting in substantially all of the bone cement being squeezed from the cartridge. An air escape passage is also provided to vent air contained within an annular gap between the agitator shaft and the cap upon initial being essentially free from entrained air.

    摘要翻译： 一种用于混合基本上不含夹带空气的骨水泥的骨水泥的方法和装置。 该装置包括具有两个伸缩筒的筒。 外筒在其上容纳密封盒的盖。 该盖包括其中安装有分离搅拌器的出口和用于连接真空泵的端口。 在使用中，在筒上抽出希望的真空压力，并且在抽真空的同时允许内筒被吸入外筒，于是当期望的真空压力为期望时，内筒自动停止相对于外筒移动 到达。 然后在由此产生的部分真空下进行骨水泥的混合。 搅拌器桨叶对伸缩筒的两个内筒壁提供刮擦作用，从而改善混合。 混合后，将搅拌器分开，将适当的喷嘴连接到墨盒，墨盒插入水泥枪。 骨水泥的引导部分当轴向前进穿过药筒时形成凸形轮廓，并且活塞塞包括通常对应于骨粘固剂轮廓的锥形突起。 帽和桨也相应于由骨水泥开发的凸形轮廓成形，导致基本上所有的骨水泥被从筒中挤出。 还设置有空气逸出通道，用于在初始基本上没有夹带的空气时排出容纳在搅拌器轴和盖之间的环形间隙内的空气。

    摘要： A prosthetic inserter includes an inserter head having at least first and second bosses, at least one of the bosses movable from a first position to a second position, that couple the inserter to a femoral provisional component via a pair of corresponding apertures, such as drill holes, within the articulating surfaces of a selected one of a series of femoral provisional components. Each provisional component of the series is capable of having different aperture distances measured between a respective pair of apertures. The bosses of the inserter are biased into an engagement position in which the inserter can be secured to a femoral provisional component to eliminate the need for an external engagement force to be supplied to the inserter.
