Abstract
A method for preparing a proximal femoral canal of a patient during total hip replacement surgery uses a shaping instrument or broach having a proximal portion with an anterior surface, and a posterior surface, each surface being spaced apart from a medial-lateral plane through the shaping instrument. A handle portion having a proximal portion having a first longitudinal axis is connected to a transition portion having a second longitudinal axis and a distal portion having a third longitudinal axis. Wherein the handle includes a dual offset including a first compound bend between the transition portion and the proximal portion and wherein, when following a direction from the transition portion to the proximal portion, the first compound bend includes a bend in the posterior direction and a bend in the lateral direction, and wherein the first compound bend is less than 90 degrees. No plane extending through the proximal portion is coplanar with a plane extending through both the transition portion and the distal portion.
