摘要:
An apparatus for removing bone material including a distal cutting instrument and a proximal cutting instrument. The distal cutting instrument has at least one first cutting edge, a shoulder, and a shaft portion. The shaft portion has an anti-rotation feature. The at least one first cutting edge removes bone material when moved in a first direction. The proximal cutting instrument is removably attached to the shaft portion, and has a first end portion and a second end portion. The second end portion contacts the shoulder of the distal reamer when the proximal reamer is mounted to the shaft portion. The proximal reamer has at least one second cutting edge and an aperture. The aperture is adapted to receive the anti-rotation feature of the shaft portion of the distal reamer. The at least one second cutting edge removes bone material when moved in a second direction.
