Claim 28:
29. An instrument for reaming bone, comprising:
a handle having a proximal end, a distal end, an inner throughbore extending therebetween, and a release collar slidably disposed along the distal end;
a reamer head having a distally-facing cutting surface configured to cut bone;
a housing having an elongate shaft with a proximal end, a distal end, an inner throughbore extending therebetween, and a reamer attachment component formed at the distal end of the housing, the reamer attachment component being configured to removably couple the housing to the reamer head, and the reamer attachment component including an opening having a longitudinal axis that extends at an oblique angle relative to the inner throughbore of the elongate shaft; and
a drive shaft having a proximal end configured to couple to a power source and a distal end, the drive shaft extending through the inner throughbore of the handle and the inner throughbore of the housing such that the distal end of the drive shaft is configured to be located within the opening of the reamer attachment component;
wherein the release collar is configured to receive the proximal end of the housing and selectively lock the housing relative to the handle in one of a plurality of positions, each of the plurality of positions corresponding to a different rotational orientation of the housing around a longitudinal axis of the handle.
