Abstract
An apparatus () for removing bone material comprises 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 (). The proximal cutting instrument () 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.
