Claim:
A bone miller system comprising: a shell configured for insertion within a bone cavity and including a shaft cavity; a frame shaft configured for sliding reception into the shaft cavity along a longitudinal axis of the shaft cavity; at least one cutter defining a cutter axis, the at least one cutter including a first drive joint member; a cutter mount configured to support the at least one cutter such that the cutter axis intersects the longitudinal axis at a first angle; a drive shaft defining a drive shaft axis, the drive shaft including a proximal end configured to receive rotational force to rotate the drive shaft about the drive shaft axis, and a distal end with a second drive joint member, the second drive joint member configured to operably couple with the first drive joint member to rotate the at least one cutter about the cutter axis; and a shaft alignment bracket configured to support the drive shaft at a fixed angular relationship with respect to the frame shaft, such that the drive shaft axis intersects the cutter axis at a second angle, wherein the second angle is about equal to or greater than the first angle.
