1. A Cam resection guide for evaluating a spherical contour of a bone that has undergone a Cam resection comprising:
- a handle having a distal end; and
a tip member that is coupled to the distal end of the handle by a spherical joint such that the tip member can both rotate and pivot relative to the handle, wherein the tip member is coupled to the handle at an attachment point located between a front edge and a rear edge of the tip member, the tip member having a spherical shaped bottom surface for evaluating the spherical contour of the bone by being moved therealong, wherein a body of the spherical joint that is formed at the distal end of the handle has a flattened top surface to cause a truncation of an outer contour of the spherical joint and permit the guide to be received internally within a cannula for delivering the guide to a target site, wherein the tip member includes a first suture attachment hole formed between the attachment point and the rear edge of the tip member, the first suture attachment hole being configured to receive a first suture and positioned such that when the first suture is pulled in a rearward direction, a rear portion of the tip member that terminates at the rear edge and is closest to the handle, pivots about the spherical joint in a direction toward the handle to permit reception of the guide within the cannula.

12. A Cam resection guide for evaluating a spherical contour of a bone that has undergone a Cam resection and being configured for delivery through a cannula to a target site comprising:
-
a handle having a distal end that has a spherical shape to define a spherical joint; and a tip member that is coupled to the spherical joint of the handle at an attachment location such that the tip member has two degrees of freedom relative to the handle, the tip member having an arcuate shape with a concave shaped bottom surface for evaluating the spherical contour of the bone by being moved therealong, wherein the tip member has an arcuate shape with the trailing and leading edges defining opposing free ends of the body, the attachment location being centrally located within tip member such that a distal portion of the tip member lies between the attachment location and the leading edge and a proximal portion of the tip member lies between the attachment location and the trailing edge, wherein first and second suture attachment holes are formed in the proximal portion and configured to receive sutures that can be pulled to allow the rear portion of the tip member to be pivoted in a direction toward the handle to position the tip member relative to the handle to permit reception into and travel of the guide within the cannula. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A Cam resection guide for evaluating a spherical contour of a bone that has undergone a Cam resection and configured to be delivered through a cannula to the bone, comprising:
-
a handle having a distal end that has a spherical shape to define a spherical joint; and a tip member that is coupled at an attachment location to the spherical joint of the handle such that the tip member has two degrees of freedom relative to the handle, the tip member having a leading edge that is distal to the handle, a trailing edge, and a concave shaped bottom surface for evaluating the spherical contour of the bone by being moved therealong, the leading edge defining a first free end of the tip member and the trailing edge defining an opposite second free end of the tip member, wherein the tip member includes a first window formed between the trailing edge and the attachment location and a second window formed between the leading edge and the attachment location, wherein the first window comprises a first opening and the second window comprises a second opening, wherein the tip member includes a first suture attachment hole formed proximate both a first corner of the tip member and the trailing edge and a second suture attachment hole formed proximate both a second corner of the tip member and the trailing edge, wherein the first and second suture attachment holes are configured to receive sutures that permit the trailing edge of the tip member to be raised in a direction toward the handle to obtain a compact orientation that allows reception of the guide within the cannula.
