Publication number: 20180064449Abstract: An orthopedic guide for preparing a particular patient's bone to receive a prosthesis using a milling tool with a rotating burr comprises a platform having a top surface and a bottom surface adapted to face the patient's bone. The platform defines an elongate milling track that extends through the platform from the top surface to the bottom surface of the platform, the milling track being sized and shaped so as to be adapted to guide the milling tool across the patient's bone with the burr of the milling tool rotating beneath the bottom surface of the platform to be adapted to remove a first bone portion from the patient's bone. A plurality of legs are coupled to the platform and each comprise a referencing end that is contour-matching fabricated as a function of the patient's bone data to be adapted to abut the patient's bone, the referencing ends of the plurality of legs adapted to cooperate to locate the orthopedic guide at a single predetermined location of the patient's bone.Type: ApplicationFiled: November 7, 2017Publication date: March 8, 2018Inventors: Anthony P. Romano, Justin J. May

Patent number: 9375303Abstract: Methods of ordering and manufacturing orthopedic components eliminate the need to stockpile and inventory large volumes of implants and instruments. In one exemplary embodiment, the surgeon begins by acquiring anatomical data from a patient. The anatomical data may then be loaded into a data comparison program. The data comparison program performs a best-fit analysis by comparing the patient's anatomical data to a number of predesigned, tested, and validated virtual implant models that are stored in a database. Once an implant has been identified by the data comparison program for the individual patient, the surgeon may place an order electronically with the manufacturer via the internet. In one exemplary embodiment, when placing the order, the surgeon will specify the type of implant, the surgery date, specific patient information, shipping information, and the preferred surgical technique that the surgeon anticipates using.Type: GrantFiled: April 14, 2011Date of Patent: June 28, 2016Assignee: Zimmer, Inc.Inventors: Kevin S. Cook, James E. Grimm, Anthony P. Romano

Patent number: 9132014Abstract: The present disclosure provides knee prostheses that replicate at least a portion of the function of an individual patient's anterior cruciate ligament (ACL). An exemplary knee prosthesis includes a femoral component configured to be implanted on the distal end of the patient's femur and a tibial component configured to be implanted on the proximal end of the patient's tibia. In extension, the femoral component and the tibial component may cooperate to limit anterior movement of the tibial component relative to the femoral component. In flexion, the femoral component may be free to rotate relative to the tibial component.Type: GrantFiled: April 13, 2011Date of Patent: September 15, 2015Assignee: Zimmer, Inc.Inventors: Adam H. Sanford, Vincent A. Webster, Dwight T. Todd, Anthony P. Romano, Christopher M. Byrd, Jody L. Claypool, Raymond C. Parisi

Patent number: 9039710Abstract: A prosthetic inserter includes an inserter head having at least first and second bosses, at least one of the bosses movable from a first position to a second position, that couple the inserter to a femoral provisional component via a pair of corresponding apertures, such as drill holes, within the articulating surfaces of a selected one of a series of femoral provisional components. Each provisional component of the series is capable of having different aperture distances measured between a respective pair of apertures. The bosses of the inserter are biased into an engagement position in which the inserter can be secured to a femoral provisional component to eliminate the need for an external engagement force to be supplied to the inserter.Type: GrantFiled: December 7, 2010Date of Patent: May 26, 2015Assignee: Zimmer, Inc.Inventors: Jeff Blaylock, Jody L. Claypool, Stephen H. Hoag, Anthony P. Romano

Patent number: 8795282Abstract: A surgical instrument and method determine the orientation of the mechanical axis of a femur. The instrument may include a rod with a first end of the rod rotatably secured at a first point on the surface of distal femur that corresponds to center of the knee joint so that the first end is coincident with the mechanical axis. The connection between the first end of the rod and the distal end of the femur defines a first point of rotation. The second end of the rod is slideably received within a sleeve that is rotatably connected to a support positioned distally away from the distal end of the femur. The connection between the sleeve and the support defines a second point of rotation. When the distance between the first and second points of rotation is minimized, a line drawn therebetween is coincident with the mechanical axis of the femur.Type: GrantFiled: January 28, 2010Date of Patent: August 5, 2014Assignee: Zimmer, Inc.Inventors: Brian D. Earl, Anthony P. Romano, Jody L. Claypool
