System and method for joint resurfacing and repair
First Claim
1. An implant resection system for preparing an implant site to replace a defect in an articular surface of a first bone, said implant resection system comprising:
- a first guide configured to be coupled to a first bone, said first guide comprising;
a body portion having at least one channel defined on a portion thereof, said channel configured to extend generally perpendicular to a portion of said first bone proximate to said defect;
an arm extending outwardly from a distal face of said body portion of said first guide; and
a spoon disposed about a distal end of said arm, said spoon configured to be disposed between said articular surface of said first bone and an articular surface of a second cooperating bone;
at least one pin configured to be received and retained within said channel, said pin having a distal end configured to pierce said first bone and to extend and form a longitudinally disposed bore within said first bone; and
an implant comprising;
a load bearing surface having a contour substantially corresponding to a contour of said articular surface corresponding to said implant site; and
a bone facing surface having a contour substantially corresponding to a contour of said implant site formed in said first bone.

Abstract
An implant resection system for preparing an implant site to replace a defect in an articular surface of a first bone includes a first guide configured to be coupled generally to the first bone. The first guide includes a body portion defining a channel configured to receive a pin, wherein the pin is configured to penetrate and form a longitudinally disposed bore within the first bone. The implant resection system further includes a second guide configured to be coupled generally perpendicular to the first bone proximate to the defect by way of the bore. The second guide includes a drill bit configured to form an excision site through a portion of the articular surface in preparation of receipt of an implant.

12. A method for preparing an implant site to replace a defect in an articular surface of a bone, said method comprising:
-
securing a first guide to a bone, said first guide comprising a body portion having at least one channel defined on a portion thereof, said channel configured to extend generally perpendicular to a portion of said bone proximate to said defect; advancing at least one pin along said channel and into said bone and forming a longitudinally disposed bore within said bone; removing said pin from said bone; securing a second guide generally perpendicular to said bone proximate to said defect using a rod member received within and advanced through a first passageway and into a portion of said bore in said bone, said second guide comprising a body portion having a handle member disposed at one end and said first passageway and a second passageway defined on an opposing end, said passageways each defining a generally cylindrical core pathway configured to extend generally perpendicular to said bone; and advancing a drill bit partially through said second passageway proximate to said defect in said bone; and moving said second guide from a first position to a second position relative said bone and said defect to form an excision site on said bone. - View Dependent Claims (13, 14, 15)
