    摘要： A method of shaping a bone screw with an automated device having a CNC unit includes rotating a blank coupled to a spindle about an axis defined by a coordinate system of the CNC unit, advancing a cutting tool proximally through an exterior of the blank at a speed to form a helical thread along a shaft, and reducing the speed to provide a variable, proximally decreasing pitch along at least a portion of the shaft. A first cutting tool is automatically transitioned toward disengagement from the blank when 1) a relative axial position between the first cutting tool and the blank coincides with a first coordinate of a predetermined location, and 2) a relative rotational position between the first cutting tool and the blank coincides with a second coordinate of the predetermined location. The first coordinate is along the axis, the second coordinate is an angular position about the axis, and the first and second coordinates are defined by the coordinate system. A second cutting tool is moved into engagement with the exterior of the blank so that the second cutting tool engages the blank substantially at the predetermined location, in a manner enabling continuation of the thread.

    摘要： A fixation device includes an outer member, an inner member, and an expansion member. The outer member includes an elongated body portion and a slotted tail portion, and defines a central bore therethrough that extends along a central longitudinal axis. The inner member is disposed within the central bore of the outer member, and the expansion member is coupled to the inner member. Proximal movement of the inner member relative to the outer member moves the expansion member into the slotted tail portion of the outer member such that the slotted tail portion moves from an undistended configuration to a distended configuration.
