An orthopaedic surgical instrument comprising a metallic customized patient-specific surgical instrument is disclosed. The metallic customized patient-specific surgical instrument includes a base plate sized to be positioned on a resected surface of a distal end of a patient's femur, an anterior resection guide body attached to, and extending from, the distal surface of the base plate to a free distal end, a posterior resection guide body attached to, and extending from, the distal surface to a free distal end, and a pair of chamfer resection guide bodies attached to, and extending from, the distal surface.

Customized patient-specific surgical instrument systems and methods

An orthopaedic surgical instrument includes an all-polymer 4-in-1 cutting block having a number of polymer cutting guides. In some embodiments, the all-polymer cutting block is be embodied as a multi-piece cutting block, while in other embodiments the all-polymer cutting block is embodied as a single, monolith cutting block. Several methods for fabricating the different all-polymer 4-in-1 cutting blocks are also disclosed.

Customized patient-specific instruments configured to be selectively attached at predetermined locations of a patient's bone are disclosed. The customized patient-specific instruments may include a polymeric body including a bone-facing surface having a customized patient-specific negative contour shaped to match and receive a corresponding positive contour of the patient's bone at the predetermined location. The customized patient-specific instruments also include a metallic coating that defines one or more cutting slots. A method of performing an orthopaedic surgical procedure is also disclosed.

Customized patient-specific surgical instruments and method

An orthopaedic surgical instrument includes a customized patient-specific 5-in-1 cutting block having a plurality of ribs and cutting guide slots extending between each rib. A bone-facing surface of each rib has a customized patient-specific negative contour configured to receive a portion of a corresponding positive contour of the patient's femur.

A bone reamer includes a first member having a first hub and a second member having a second hub. The first hub can extend along a first axis and have a pair of elongated cutting arms that are fixed to the first hub. The elongated cutting arms can extend along a second axis that is generally perpendicular relative to the first axis. The first hub can define a track thereon. The second hub can extend along a third axis. The second member can have a second pair of elongated cutting arms that are fixed to the second hub and extend along a fourth axis that is generally perpendicular to the third axis. The second member can have a track follower extending thereon and that is configured to slidably advance along the track causing the first and second members to move between a collapsed position and an expanded position.
