Abstract:
1. A method of preparing a bone for insertion of a prosthesis, said method comprising: forming a bone canal in a bone utilizing a surgical instrument, the surgical instrument having distal and proximal ends, the distal end including a reaming portion having a first longitudinal axis and the proximal end including at least one guide borehole having a second longitudinal axis parallel and offset to the first longitudinal axis; forming at least one anti-rotation recess in said bone along the second longitudinal axis, said at least one anti-rotation recess having a longitudinal axis coaxial with the second longitudinal axis and having a channel profile that is perpendicular to first and second longitudinal axes of the surgical instrument; engaging a trial component having a joint connection element to said surgical instrument; implanting the surgical instrument into said bone canal; moving said trial component while said trial component is engaged to said surgical instrument, and while said surgical instrument is maintained in said bone canal, to determine an implanting position for said prosthesis; marking said implanting position on said bone by using said surgical instrument as a guide; removing said surgical instrument engaged to said trial component from said bone canal; and implanting said prosthesis in said marked implanting position in said bone.
