    摘要： A milling system is disclosed for creating a cavity in a bone. The cavity has a cross section which has a generally triangular profile having a first side generally parallel with an axis of the bone and a second side forming an acute angle with the first side. The cavity is contiguous with a pre-existing conical cavity in the bone. The system comprises a drive shaft, a frame for carrying a cutter and a cutter for cutting the cavity. The drive shaft has a proximal end configured for coupling to a drive means and a distal end configured to form a portion of a drive joint for coupling the drive shaft to a cutter. The frame includes a shaft and a cutter mount for mounting a cutter at a first angle approximating the acute angle with respect to the shaft. The mount includes a bracket extending laterally from the shaft to a bearing configured to receive a portion of a cutter and maintain the received cutter oriented at the first angle during rotation. The cutter has a head configured to form a portion of a drive joint for coupling the cutter to a drive shaft. The drive shaft is coupled to the cutter to form the drive joint. The cutter is received in the mount at the first angle and the drive shaft forms a second angle with the longitudinal axis less than the first angle.

    摘要： A tool for separating components of a modular prosthesis includes an upper and lower body, each defining opposing bills at one end that are sized to fit in juxtaposed relation within an initial gap between the components. The upper body is provided with a handle so that the tool may be manually held by the surgeon with the opposing bills in position in the prosthesis. The tool includes a jack assembly disposed between the upper and lower bodies of the tool that is configured to be driven into an extended position, gradually separating the upper and lower bodies, and consequently exerting a separation force on the prosthesis components through the bills of the tool. The jack assembly is driven by a threaded actuator rod that bears against one element of the jack assembly as the actuator rod is rotated within a threaded bore in one of the bodies of the tool.

The drive shaft has a proximal end and a distal end forming a portion of a drive joint for coupling the drive shaft to a cutter. The frame includes a frame shaft and a cutter mount, mounting a cutter at a first angle. The mount includes a bearing bracket extending laterally from the frame shaft to a bearing receiving a portion of a cutter and maintains the received cutter oriented at the first angle during rotation. The cutter has a head forming a portion of drive joint for coupling the cutter to a drive shaft. The cutter is received in the mount at the first angle and the drive shaft forms a second angle with the longitudinal axis less than the first angle.
