SYSTEM AND METHOD FOR ASSISTING WITH ATTACHMENT OF A STOCK IMPLANT TO A PATIENT TISSUE
First Claim
1. A method of attaching a stock prosthetic implant to a patient tissue, the stock prosthetic implant including a plurality of fastener apertures extending therethrough, the method comprising the steps of:
- placing a lower implant surface of the stock prosthetic implant into contact with the patient tissue in a predetermined implant orientation;
providing a guide having a lower guide surface contoured to substantially mate with at least a portion of an upper implant surface of the stock prosthetic implant, an upper guide surface spaced longitudinally apart from the lower guide surface by a guide body, at least one guiding aperture extending through the guide body between the upper and lower guide surfaces at a predetermined aperture location with respect to the guide body, and two or more locating protrusions extending from the lower guide surface toward the upper implant surface for engaging the upper implant surface, the two or more locating protrusions being spaced apart from the at least one guiding aperture;
defining a target trajectory through the guide body using the at least one guiding aperture, the target trajectory and the predetermined aperture location of the at least one guiding aperture being preselected responsive to preoperative imaging of the patient tissue;
placing the lower guide surface into mating contact with the at least a portion of the upper implant surface in a predetermined relative guide/implant orientation;
placing a chosen one of the at least one guiding aperture of the guide into a collinear relationship with a chosen one of the plurality of fastener apertures of the stock implant, and nesting the two or more locating protrusions of the guide into preselected ones of the plurality of fastener apertures of the stock prosthetic implant, wherein the guide and the guide and the stock prosthetic implant are engaged together in a fixed rotational orientation relationship when the two or more locating protrusions are nested with the preselected ones of the plurality of fastener apertures, such that relative rotation between the guide and the stock prosthetic implant is prevented in the fixed rotational relationship; and
at least one of guiding a surgical tool through the chosen guiding aperture and the chosen one of the plurality of fastener apertures and inserting the surgical tool into the patient tissue along the target trajectory to create a fastener cavity in the patient tissue; and
guiding a fastener through the chosen one of the plurality of fastener apertures and into the patient tissue along the target trajectory.

Abstract
A guide for assisting with attachment of a stock prosthetic implant to a patient tissue includes a lower guide surface configured to contact an upper implant surface of the stock prosthetic implant when a lower implant surface of the stock prosthetic implant contacts the patient tissue. An upper guide surface is accessible to a user when the lower guide surface is in contact with the upper implant surface. At least one guiding aperture extends through the guide body between the upper and lower guide surfaces at a predetermined aperture location with respect to the guide body and defines a predetermined target trajectory through the guide body. At least one of the target trajectory and the aperture location of each guiding aperture is preselected responsive to preoperative imaging of the patient tissue. A method of assisting with attachment of a stock prosthetic implant to a patient tissue is also provided.

33. A method of attaching a stock prosthetic implant to a patient tissue using a guide, the stock prosthetic implant including a lower implant surface, an upper implant surface, and a plurality of fastener apertures extending between the lower and upper implant surfaces, the guide including a lower guide surface contoured to at least partially mate with the upper implant surface of the stock prosthetic implant, an upper guide surface spaced longitudinally apart from the lower guide surface by a guide body, and at least one guiding aperture extending through the guide body between the upper and lower guide surfaces, the method comprising the steps of:
-
providing the guide with two or more locating protrusions extending from the lower guide surface toward the upper implant surface for engaging the upper implant surface, the two or more locating protrusions being spaced apart from the at least one guiding aperture; preselecting a target trajectory for a fastener though a chosen one of the plurality of fastener apertures of the stock prosthetic implant responsive to preoperative imaging of the patient tissue; placing the lower implant surface of the stock prosthetic implant into contact with the patient tissue in a predetermined implant orientation, and placing the lower guide surface of the guide into mating contact with the upper implant surface of the stock prosthetic implant; aligning the at least one guiding aperture of the guide into a collinear relationship with the chosen one of the plurality of fastener apertures of the stock prosthetic implant, the target trajectory extending through both the at least one guiding aperture and the chosen one of the plurality of fastener apertures; engaging the guide and the stock prosthetic implant together in a fixed rotational orientation relationship by nesting the two or more locating protrusions of the guide into preselected ones of the plurality of fastener apertures of the stock prosthetic implant, wherein relative rotation between the guide and the stock prosthetic implant is prevented in said fixed rotational relationship; and guiding a fastener along the target trajectory through the at least one guiding aperture and the chosen one of the plurality of fastener apertures, and into the patient tissue to attach the stock prosthetic implant to the patient tissue. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42)
