1. A resection guide locator for use in resecting a bone having a surface topography comprising:
- a bone engagement portion having a surface that is complementary to said surface topography of said bone to be resected; and
a socket sized to receive a resection guide so as to maintain said resection guide in position while said surface of said one engagement portion is arranged in contacting relation with the bone,wherein an elongate slot and a pair of through holes are defined within the socket, the elongate slot and pair of through holes are positioned within the socket such that they respectively align with an elongate slot and a pair of through holes defined by the resection guide when the resection guide is received within the socket, andwherein the elongate slot and pair of through holes defined within the sockets are disposed at a distance from one another such that they do not intersect.

Abstract
A resection guide locator includes a bone engagement portion with surfaces that are complementary to the surface topographies of a bone to be resected during surgery. A housing includes a socket defined by a resilient annular wall that is sized and arranged so to accept a resection guide by press-fit to thereby position and hold the resection guide within he socket. The resection guide is maintained in a predetermined, preferred position while the surfaces are releasably locked in position on the bone. A method is disclosed for forming and using the resection guide locator.

11. A resection guide locator for use in resecting a boric having a surface topography comprising:
-
a bone engagement portion having a surface that is complementary to said surface topography of said bone to be resected; and a socket defined by a resilient wall arranged for storing energy when a resection guide is press-fit in said socket and operatively engages a portion of said wall so as to maintain said resection guide in position while said surface of said bone engagement portion is arranged in contacting relation with the bone, wherein an elongate slot and a pair of through holes are defined within the socket, the elongate slot and pair of through holes are positioned within the socket such that they respectively align with an elongate slot and a pair of through holes defined by the resection guide when the resection guide is received within the socket, and wherein the elongate slot and pair of through holes defined within the socket are disposed at a distance from one another such that they do not intersect. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A resection guide locator for use in resecting to bone having a surface topography comprising:
-
a bone engagement portion having a surface that is complementary to the surface topography of said bone to be resected; and a socket sized to receive by press-fit a resection guide having a resection slot so as to maintain said resection slot defined by the resection guide in a substantially fixed orientation relative to the bone engagement portion while said surface of said bone engagement portion is arranged in secure interlocking relation with said bone surface, wherein an elongate slot and a pair of through holes are defined within the socket, the elongate slot and the pair of through holes are positioned within the socket that they respectively align with the resection slot and a pair of through holes defined by the resection guide when the resection guide is received within the socket, and wherein the elongate slot and pair of through holes defined within the socket are disposed at a distance from one another such that they do not intersect. - View Dependent Claims (19, 20, 21, 22, 23, 24)

25. A resection guide mount comprising:
-
a bone engagement portion having two surfaces that are complementary to respective separate surface topographies of a bone to be resected; and a housing portion attached to said bone engaging portion having a socket defined by a resilient annular wall that is sized and arranged so to accept a resection guide by press-fit, to thereby position and hold said resection guide within said socket and thereby maintain said resection guide in a predetermined position while said two surfaces of said bone engagement portion is arranged in secure interlocking relation with said two separate surfaces of bone to be resected, wherein the housing portion defines an elongate slot, and a pair of through holes within the socket, the elongate slot and pair of through holes are positioned within the socket such that they respectively align with an elongate slot and a pair of through holes defined by the resection guide when the resection guide is received within the socket, and wherein the elongate slot and the pair of through holes defined within the socket are disposed at a distance from one another such that they do not intersect.

26. A resection guide locator comprising:
-
a base sized to engage a portion of a bone to be resected having a surface that is topographically complementary to the surface topography of said bone; and a housing attached to said base comprising a socket defined by a resilient peripheral wall arranged for storing energy when a resection guide is press-fit in said socket so as to operatively engage said wall thereby maintaining said guide in a predetermined position relative to said one while said topographically complementary surface of said bone engagement portion is arranged in secure interlocking relation with said bone surface, wherein the housing portion defines an elongate slot and a pair of through holes within the socket, the elongate slot and pair of through holes are positioned within the socket such that they respectively align with an elongate slot and a pair of through holes defined by the resection guide when the resection guide is received within the socket, and wherein the elongate slot and the pair of through holes defined within the socket are disposed at a distance from one another such that they do not intersect.

27. A method for forming a resection guide locator comprising the steps of:
-
(A) generating an anatomically accurate image of a bone that includes surface topographies; (B) converting said anatomically accurate image to a digital model; (C) adding a digital representation of a resection guide locator to said digital model so as to form a composite digital model; (D) mapping one of said surface topographies complementarily onto a bone engagement portion of said resection guide locator; and (E) manufacturing said resection guide locator based upon said composite digital model so that a manufactured resection guide locator is formed including said complementary surface topography on a bone engagement portion and a receptacle pocket sized to receive a resection guide with a press-fit, the resection guide locator defining an elongate slot and a pair through holes within the receptacle pocket, the elongate slot and pair of through holes are positioned within the receptacle pocket such that they respectively align with an elongate slot and a pair of through holes defined by the resection guide when the resection guide is received within the receptacle pocket, wherein the elongate slot and the pair of through holes defined within the receptacle pocket are disposed at a distance from one another such that they do not intersect.
