摘要：
An apparatus (10) for removing bone material comprises a distal cutting instrument(12) and a proximal cutting instrument (14). The distal cutting instrument hasat least one first cutting edge (30), a shoulder (20), and a shaft portion (22).The shaft portion (22) has an anti-rotation feature. The at least one first cuttingedge (30) removes bone material when moved in a first direction. The proximalcutting instrument (14) is removably attached to the shaft portion (22). Theproximal cutting instrument (14) has a first end portion (68) and a second endportion (66). The second end portion (66) contacts the shoulder (20) of the distalreamer (12) when the proximal reamer is mounted to the shaft portion (22). Theproximal reamer (14) has at least one second cutting edge (32) and an aperture.The aperture is adapted to receive the anti-rotation feature of the shaft portion(22) of the distal reamer (12). The at least one second cutting edge (32) removesbone material when moved in a second direction.
