Patient-specific humeral guide designs
First Claim
1. A method of resecting or resurfacing a humeral head using a humeral cut guide, the method comprising:
- positioning a bone-engagement member along a humeral head surface of a humeral bone;
positioning a registration member along a bicipital groove surface of a humeral bone;
squeezing the registration member and the bone-engagement member to cause bending of the registration member relative to the bone-engagement member and thereby ensure seating of the humeral cut guide;
sliding a cut guide plate along an elongate member extending from the humeral cut guide to engage the humeral head surface of the humeral bone; and
resecting or resurfacing the humeral head using a cutting device engaged with the cut guide plate.

Abstract
A humeral cut guide system for a humeral head comprises: a bone-engagement member including a first patient-specific bone-engagement surface that is complementary and made to substantially mate and nest in only one position on a specific patient'"'"'s humeral head; a registration member connected to the bone-engagement member including a second patient-specific bone engagement surface that is sized and made to substantially mate and nest in only one position with the specific patient'"'"'s bicipital groove; a first protrusion extending from the registration member and having a first surgeon-engaging surface for manipulation by a surgeon; and a cut guide plate connected to and extending away from the registration member such that, upon the bone-engagement member mating and nesting with the specific patient'"'"'s humeral head, the cut guide plate is spaced apart from the humeral head, wherein the cut guide plate defines an elongate slot.

12. A method of resecting or resurfacing a humeral head using a humeral cut guide member including a bone-engagement member that includes a first patient-specific bone-engagement surface that is complementary and made to substantially mate and nest in only one position on a specific patient'"'"'s humeral head, and including a cut guide plate connected to the bone-engagement member, the method comprising:
-
affixing the humeral cut guide member to the only one position of the specific patient'"'"'s humeral head; selectively adjusting a position of the cut guide plate relative to the specific patient'"'"'s humeral head by moving the cut guide plate along an elongate member; orienting a proximal end of a registration member connected to the humeral cut guide member into the specific patient'"'"'s bicipital groove, the registration member being connected to the humeral cut guide member and including a second patient-specific bone engagement surface that is sized and made to substantially mate and nest in only one position with the specific patient'"'"'s bicipital groove; wherein; the proximal end of the registration member is connected to a first end of the bone-engagement member and to the elongate member; and a distal end of the registration member extends from the proximal end and is connected to a first protrusion; and manipulating the humeral cut guide member using the first protrusion and a second protrusion extending from the proximal end of the registration member proximate the bone-engagement member. - View Dependent Claims (13, 14, 15, 16, 17)
