Abstract
An orthopaedic surgical instrument assembly includes an instrument handle configured to clamp a broach and femoral stem trial assembly. A depth stop is configured to removably couple to the instrument handle. When the broach and femoral stem trial are advanced into a medullary canal of a patient's femur, a substantially planar proximal surface of the depth stop is configured to engage the distal surface of the femur, determining the depth of the broach in the medullary canal. The proximal surface of the depth stop is parallel to the joint line, defining an oblique angle to the anatomical axis of the femur. The depth stop may be attached to the instrument handle at a number of positions to control the depth of the broach. The assembly may include a spacer plate removably coupled to the depth stop that distalizes the broach in the medullary canal.
