Embodiment Construction

[0039] Exemplary embodiments will now be described more fully with reference to the accompanying drawings.

[0040]The present disclosure generally provides patient-specific surgical instruments including, for example, alignment guides, drill guides, and devices for use in shoulder arthroplasty, shoulder resurfacing, and joints with or with the shoulder, including Other tools used in other procedures involving multiple bones including the humeral head. The present disclosure can be applied to anatomical shoulder arthroplasty and reverse shoulder arthroplasty. Patient-specific instruments may be used with conventional implant components or with patient-specific implant components and / or bone grafts prepared using computer-aided imaging methods according to the present disclosure. Medical scans (e.g., MRI, CT, ultrasound, x Computer modeling of three-dimensional images of the patient's anatomy, patient-specific prosthetic components, and patient-specific guides, templates, and...

Abstract

A humeral cutting guide member for a humeral head may include a bone engaging member including a first patient-specific bone engaging surface that is complementary and made to substantially only fit and overlap placed in a position on the humeral head of a particular patient; a registration member connected to the bone engaging member, the registration member including a second patient-specific bone engaging surface, the second patient-specific bone engaging surface being determined sized and made to fit and overlap approximately with the biceps groove of a particular patient only in one position; and a cutting guide plate that is connected to the bone engaging member and extends away from The patient's humeral head engages and overlaps, and the cutting guide is spaced from the humeral head, wherein the cutting guide defines an elongated groove.

Description

[0001] claim priority [0002] This application claims the benefit of U.S. Patent Application No. 14 / 750,325, filed June 25, 2015, and claims the benefit of U.S. Patent Application No. 15 / 073,223, filed March 17, 2016, thereby claiming these U.S. Priority of patent applications and these US patent applications are hereby incorporated by reference in their entirety. technical field [0003] The present disclosure relates to humeral cutting guide members. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] During shoulder arthroplasty, the humerus may need to be resurfaced or resected in order to receive a shoulder implant. Before surgery, doctors typically take multiple images of the surgical area, including the humerus, via X-rays, CT, ultrasound, MRI, or PET. Based on these images, physicians can determine the best surgical plan for resurfacing or resectioning the humeru...
