Abstract
A surgical instrument is disclosed that facilitates the implantation of one of a number of differently sized or differently configured hip stem prostheses into a proximal end of a femur while also providing a surgeon with a substantial amount of rotational control over the prosthesis during the implantation. A suitable hip stem prosthesis is selected from a family of hip stem prostheses of varying sizes and dimensions. The surgical instrument attaches to the selected hip stem prosthesis via first and second spaced engagement portions such that the instrument is operable to exert rotational control over the selected hip stem prosthesis. The first engagement portion is an impaction portion configured to engage a corresponding impaction feature on a proximal body portion of the hip stem prosthesis. The second engagement portion is an adjustable clamping portion configured to clampingly receive the neck of the hip stem prosthesis, regardless of the prosthesis size.
