Принадлежит: DePuy Products, Inc.

A femoral prosthesis system is provided which includes femoral prosthesis and an instrument for inserting/extracting the femoral prosthesis. The femoral prosthesis includes a stem and a neck portion. The stem includes a proximal end portion which defines a proximal stem axis. The neck portion is located proximally of the proximal end portion. The neck portion includes a proximal surface and an insertion/extraction cavity which extends distally from the proximal surface. The insertion/extraction cavity is configured to couple with the insertion/extraction instrument. The insertion/extraction cavity defines an insertion/extraction cavity axis which, when projected onto a coronal plane including the proximal stem axis, is not parallel with the proximal stem axis. The insertion/extraction instrument includes a distal end portion configured to couple with the insertion/extraction cavity. 1. A femoral prosthesis comprising:a stem including a proximal end portion defining a proximal stem axis;a neck portion located proximally of the proximal end portion; andan insertion/extraction cavity extending distally from a proximal surface of the neck portion and configured to couple with an insertion/extraction instrument, the cavity defining an insertion/extraction cavity axis which, when projected onto a coronal plane including the proximal stem axis, is not parallel with the proximal stem axis.2. The femoral prosthesis of claim 1 , wherein when the insertion/extraction cavity axis is projected onto the coronal plane the insertion/extraction cavity axis extends proximally and medially from the proximal stem axis.3.

An orthopaedic surgical instrument system including a reamer assembly is disclosed. The reamer assembly includes a reamer head having a plurality of cutting teeth and a mounting bracket configured to be coupled to a femoral broach, which is sized to be positioned in a proximal opening of a femoral canal of a patient's femur. When the mounting bracket is coupled to the femoral broach, the reamer head is offset medially from the lateral edge of the femoral broach to resect a medial calcar of the patient femur. 1. An orthopaedic surgical instrument system , comprising:a first orthopaedic surgical instrument including an elongated body sized to be positioned in a femoral canal of a patient's femur and a plurality of cutting teeth defined in the elongated body, anda second orthopaedic surgical instrument including a reamer head configured to resect a portion of a proximal end of the patient's femur and a mounting bracket configured to pivotally couple the reamer head to the proximal end of the first orthopaedic surgical instrument,wherein the elongated body of the first orthopaedic surgical instrument includes a medial edge and a lateral edge positioned opposite the medial edge, andwherein when the mounting bracket is coupled to the proximal end of the first orthopaedic surgical instrument, an outer circumference of the reamer head is offset medially from the lateral edge of the elongated body such that the reamer head is positioned to resect a medial calcar of the patient's femur.2. The orthopaedic surgical instrument system of claim 1 , wherein the reamer head is operable to rotate about a first rotational axis to resect the medial calcar of the patient's femur claim 1 , and the reamer head is configured to pivot about a second rotational axis relative to the elongated body of the first orthopaedic surgical instrument to move the first rotational axis relative to the elongated body.3. The orthopaedic surgical instrument system of claim 2 , wherein the reamer head is ...
