<p>A bone reaming apparatus includes a rasp (380) and a shaft (160) coupled to the rasp. At least a first portion of the shaft is rotatable about an axis (240), and at least a portion of the rasp is extendable away from the axis. The apparatus can be used in a method for removing a mass from a bone includes drilling a bore into the bone, and expansively reaming a portion of the bore until the mass is removed from the bone. The apparatus can be used in a method for removing a femoral head from a proximal femur includes drilling a bore into the femoral head, and expansively reaming a portion of the bore until the femoral head is removed from the proximal femur.
