-
affixing a primary cut guide member to a humeral head, the primary cut guide member including a patient-specific bone-engaging surface, a primary elongate slot that defines a primary cutting plane, and including a pair of cylindrical apertures; determining whether the primary cutting plane is sufficient for the resectioning or the resurfacing of the humeral head, and if the primary cutting plane is sufficient, conducting the resectioning or the resurfacing of the humeral head; wherein if the primary cutting plane is not sufficient for the resectioning or the resurfacing of the humeral head, a pair of guide pins are coupled to the humeral head through the cylindrical apertures, the primary cut guide slot is removed, and a secondary cut guide member including a secondary elongate slot that defines a secondary cutting plane is attached to the pins. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
