1. Apparatus for broaching a bone, the apparatus comprising;

  • a rotator defining a first axis; and

    a broaching member including an edge fixed to the rotator and configured to be moved relative to the rotator to displace first bone material that is radially away from the rotator, a distal end of the broaching member looping through a distal end of the rotator to form a loop about a second axis that is transverse to the first axis so that in operation a section of the broaching member extends away from the loop and deflects around second bone material, the second bone material having a higher density than the first bone material.
