Various method and apparatuses may be used to perform a procedure, such as a resection of a portion of the anatomy for preparation of the implants of a prosthetic. Various resecting member, including saw blades having selected geometries and shapes, can be used to assist in the resection of an anatomy to provide for implantation of a prosthetic. In addition, a cutting block assembly may be used to guide the resecting member. The cutting block assembly may be moveably mounted relative to the portion to be resected.
1. An instrument for guiding a tool relative to a portion of an anatomy, comprising: a track member forming a track extending a first length between opposite ends and along a first axis;a translating member having a first portion to engage said track member such that said translating member is opera
1. An instrument for guiding a tool relative to a portion of an anatomy, comprising: a track member forming a track extending a first length between opposite ends and along a first axis;a translating member having a first portion to engage said track member such that said translating member is operable to translate relative to said track member at least parallel to said first axis and a guiding portion formed by the translating member to guide the tool relative to the anatomy, the guiding portion having a second length between opposite ends; anda positioning member operable to associate at least one of said track member or said translating member relative to the anatomy;wherein said track member is fixed to the anatomy in a track position to allow said guiding portion to translate relative to said track member along a guiding length while guiding the tool relative to the anatomy wherein said guiding length is longer than each of the first and second lengths. 2. The instrument of claim 1, wherein said track member includes a first portion operable to interconnect said track member with the anatomy and a second portion operable to engage said translating member. 3. The instrument of claim 2, wherein said second portion includes said track that is operable to engage said translating member wherein said translating member is operable to move relative to said track member along said second portion. 4. The instrument of claim 2, wherein said second portion defines a generally T-shaped portion extending from said track member operable to be engaged by said translating member. 5. The instrument of claim 2, further comprising: a member operable to interconnect said track member with the anatomy;wherein said first portion defines a bore extending through said first portion and said second member is operable to pass through said bore. 6. The instrument of claim 1, wherein the tool is a saw blade that is operable to pass through said guiding portion formed as a slot to be guided by said slot relative to the anatomy. 7. The instrument of claim 1, wherein said positioning member includes an intramedullary rod operable to be positioned in the anatomy AND wherein said positioning member includes a paddle instrument associated with said intramedullary rod to position said paddle instrument relative to the anatomy. 8. The instrument of claim 1, wherein said positioning member includes a selectable portion to assist in achieving said track position relative to the anatomy and wherein said positioning portion selects at least one of a varus or valgus position of said at least one of said track member or said translating member relative to the anatomy. 9. The instrument of claim 1, further comprising: a prosthesis operable to replace at least a portion of the anatomy. 10. The instrument of claim 1, wherein at least one of said first length or said second length is less than about 6 cm. 11. An instrument system for guiding a resection of a selected dimension of a selected portion of an anatomy, comprising: a first member fixed relative to the selected portion of the anatomy at a first position; anda second member moveable relative to said selected portion of the anatomy and moveably attached to said first member;wherein said second member defines a guide surface having a dimension less than a dimension to be resected on the selected portion of the anatomy;wherein said second member is operable to move relative to said first member to form a first guide surface at a first location and then move to a second location while said first member remains fixed at said first position to form a second guide surface at the second location;wherein a combined dimension of said first guide surface and said second guide surface at both said first location and said second location is greater than a dimension of either of said first member or said second member. 12. The instrument system of claim 11, wherein said guide surface defined by said second member includes a slot extending from a first side to a second side of said second member. 13. The instrument system of claim 11, wherein said second member includes a first side and a second side; wherein said first side is spaced from said second side at a distance of less than about 6 cm. 14. The instrument system of claim 11, wherein said first member defines a rail; wherein said second member defines a channel to operably interact with said rail to allow movement of said second member relative to said first member. 15. The instrument system of claim 11, further comprising: a resecting instrument operable to be guided with said guide surface relative to the selected portion of the anatomy;wherein the resection of the selected portion of the anatomy is completed substantially while guiding said resecting instrument with the guide surface relative to the selected portion of the anatomy. 16. An instrument for guiding a tool relative to a portion of an anatomy, comprising: a track member extending along a first axis and having a first length between a first end and a second end;a translating member having a second length between a first and a second end, said translating member including: a first portion to engage said track member such that said translating member is operable to translate substantially co-axially with said first axis of said track member; anda guiding portion formed as a slot extending through said translating member operable to guide the tool relative to the anatomy substantially parallel with said first axis, said slot having a guide surface defined between first and second guide ends, wherein said first and second lengths are less than a guiding length formed by said guide surface as said guide member moves relative to said track member where the tool is adapted to contact said guide member throughout said guiding length; anda positioning member operable to associate at least one of said track member or said translating member relative to the anatomy, wherein said positioning member includes a rod operable to extend into an intramedullary canal of the anatomy; anda connection member to selectively fix said track member to the anatomy in an associated position at least while the tool is positioned in said guiding portion. 17. The instrument of claim 16, wherein said positioning member further includes: a paddle instrument associated with said rod to position said paddle instrument against the anatomy; anda pin extending from said paddle to engage a first interconnection portion; andwherein said first interconnection portion defines an associating area to engage a second interconnection portion of said translating member. 18. The instrument of claim 17, wherein each of said paddle instrument, said pin, and said first connection portion are operable to be disconnected into individual parts. 19. The instrument of claim 16, wherein said slot of said guiding portion includes two slots each having a wall defining a throughbore that are positioned a distance from one another relative to a longitudinal axis of said rod. 20. The instrument of claim 16, wherein each of the ends of said track member are formed at an angle relative to a longitudinal surface of said track member.
