Abstract: A distal femoral joint replacement system includes a femoral component having condylar articular surfaces, a stem extending from the femoral component, and a void filler for filling a bone void within a femur. The void filler includes a body and a plurality of legs extending from the body. The body has a sidewall defining an opening for receipt of the stem which extends along a length of the body and extends through the sidewall so as to form a side-slot in the sidewall that extends along an entire length of the sidewall. The plurality of legs each have a first end connected to the body and a second end remote from the body. The legs each have an outer surface that tapers between the first and second ends and is configured to register with a corresponding inner surface of a bone void when implanted in an end of the femur.

Abstract: A cutting guide for performing a bone osteotomy procedure is disclosed. The cutting guide includes a first arm having a first cutting guide surface formed therein, a second arm having a second cutting guide surface formed therein pivotably connected to the first arm and a distractor operatively connected to the first arm. The cutting guide is adapted to be affixed to the bone such that the first cutting guide surface is open to the second cutting guide surface. The first arm and second arm are rotatable with respect to each other such that manipulation of the distractor creates a force between the first arm and the second arm causing rotation of the first arm and second arm relative to each other. A method for using the cutting guide in a bone osteotomy procedure is also disclosed.

Abstract: A surgical method for forming a void in bone includes the steps of positioning a support member securely within an intramedullary canal of a bone; attaching a guide member having a longitudinal axis to the support member in a fixed and offset relation to the intramedullary canal; connecting a cutting member having a cutting head to the guide member in a slidable arrangement along the longitudinal axis of the guide member such that the cutting head faces a first bone segment; and cutting the first bone segment along the longitudinal axis of the guide member, thereby forming a first offset bone void.

Abstract: A prosthetic femoral component includes an articular component and a bone contacting component. The articular component has a convex articular surface and a concave curved inner surface opposite the convex articular surface. The bone contacting component is least partially insertable within the articular component and has an outer side and an inner side opposite the outer side, the outer side having a convex curved surface received on and complementary to the concave curved inner surface of the articular component, and the inner side being defined by a plurality of adjacent planar segments.

Abstract: An orthopedic prosthesis includes a joint replacement portion that has a first side, a second side opposite the first side, and a screw hole that extends through the joint replacement portion from the first side and through the second side. The prosthesis also includes a peg that extends from the second side and that has a concave relief surface that partially defines the screw hole.

Abstract: A patellar resection guide includes a frame, a first jaw, and a second jaw. The frame includes a first end, at which the first jaw is disposed, and a second end opposed to the first end at which the second jaw is disposed. The guide further includes an arm with a planar surface for guiding a cutting tool. The arm is either or both of rotatable and translatable relative to the frame.

Abstract: A bone void forming assembly includes a support member having a head portion and an elongate portion extending therefrom. A guide member is connected to the support member and has a guide body including a channel extending therethrough. The channel defines an axis offset and obliquely angled relative to an axis of the elongate portion. The assembly also includes reamer having a cutting head and a stop member. A bushing is slidably connected to the reamer between the stop member and cutting head and is slidably connectable to the guide body via the channel.
