System and method for joint resurfacing and repair

摘要

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.

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; anda 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; anda bone facing surface having a contour substantially corresponding to a contour of said implant site formed in said first bone.
