An orthopaedic surgical trial instrument for use in joint remplacement (e.g., knee, hip, shoulder) surgery includes a trial body (11) of selected size and shape that can receive trial shims or wedges (20) of differing size and shape so that a surgeon can construct a trial during surgery that closely fits a patient's anatomy. Magnetic members (29) aid in holding a selected wedge to a selected trial. Corresponding projections (27, 11B) and recesses (11A, 28) prevent rotation of wedges (20) with respect to the selected trial (11). |
