Abstract: An orthopaedic surgical instrument assembly includes a tibial base trial adapted to be positioned on a surgically-prepared proximal end of a patient's tibia, an intramedullary orthopaedic surgical instrument engaged with a lower surface of the tibial base trial, and a fastener configured to pivot relative to the tibial base trial. The fastener is configured to engage with the intramedullary orthopaedic surgical instrument to removably couple the intramedullary orthopaedic surgical instrument to the tibial base trial.

Abstract: A method of surgically preparing a proximal end of a tibia includes inserting an intramedullary orthopaedic surgical instrument into a medullary canal of the tibia, securing an attachment device to the intramedullary orthopaedic surgical instrument, attaching a cutting block to the attachment device, resecting the proximal end of the tibia using the cutting block to form a surgically-prepared surface, positioning a tibial base trial on the surgically-prepared surface, and inserting a keel punch through a slot defined in the tibial base trial and into the surgically-prepared surface of the tibia.

Abstract: An orthopaedic surgical instrument assembly includes an attachment device, an intramedullary orthopaedic surgical instrument, and a cutting block. The attachment device includes a housing, a rail extending outwardly from the housing, and a mounting frame positioned on the rail that is configured to slide relative to the housing along the rail. The intramedullary orthopaedic surgical instrument is removably coupled to the housing, and the cutting block is removably coupled to the mounting frame.

Abstract: A reusable orthopaedic instrument includes a reusable orthopedic trial having a first outer surface and a second outer surface that is opposite the first outer surface. A notch is formed in each side of the orthopaedic instrument.

Abstract: An orthopaedic surgical instrument that includes a patella resection guide is disclosed. The patella resection guide includes a body having a substantially planar upper surface that defines a patella cutting guide surface and a first jaw having a first tooth, and a second jaw positioned opposite the first jaw. The second jaw is movable relative to the first jaw and includes a second tooth extending toward the first tooth that defines an axis along which the second jaw is moveable relative to the first jaw. The patella cutting guide surface defines a resection plane that extends through a patient's patella when the patella is positioned between the first jaw and the second jaw.

Abstract: An orthopaedic surgical instrument includes a patella drill guide. The patella drill guide includes a first bracket and a second bracket coupled to the first bracket and moveable relative to the first bracket. The second bracket includes a drill plate having a plurality of guide holes defined therein, and each of the plurality of guide holes is sized to receive a surgical drill. A gasket is pivotally coupled to the second bracket, and the gasket has a plurality of plugs configured to be received in the plurality of guide holes of the second bracket.

Abstract: A method of surgically preparing a patella for implantation of a patella prosthetic component is disclosed.

Abstract: An orthopaedic surgical instrument includes a patella drill guide having a first bracket, a second bracket coupled to the first bracket and moveable relative to the first bracket. The second bracket includes a drill plate having a plurality of guide holes defined therein.

Abstract: An orthopaedic surgical instrument assembly including a handle and a plurality of surgical tools configured to be selectively coupled with the handle. The handle includes a housing and a lever moveably coupled to the housing. Each surgical tool of the plurality of surgical tools includes a first clamping element and a second clamping element configured to move relative to the first clamping element. The second clamping element is configured to be coupled to the lever such that moving the lever relative to the housing advances the second clamping element toward the first clamping element to clamp a bone of a patient.

Abstract: A patella resection assembly comprises a patella resection guide and a stylus. The patella resection guide has bone-gripping members on two movable arms and a saw guide surface. The stylus is pivotably mounted to the arms of the resection guide and has a free end received in the slot in the resection guide. The arms of the patella resection guide are movable to a variety of positions with different distances between the bone-gripping members while the stylus is in place.

Abstract: A system for the internal fixation of a fractured bone of an elbow joint of a patient includes at least one bone plate, each bone plate having a plurality of holes and generally configured to fit an anatomical surface of the fractured bone. The at least one plate is adapted to be customized to the shape of a patient's bone. The system also includes a plurality of fasteners including at least one locking fastener for attaching the bone plate to the bone. At least one of the holes is a threaded hole. Guides for plate benders, drills, and/or K-wires can be pre-assembled to the threaded holes, and the locking fastener can lock into any of the threaded holes after the guides are removed.
