Embodiment Construction

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

[0040] The present disclosure mainly provides patient-specific surgical instruments. These patient-specific surgical instruments include, for example, alignment guides, drill guides, and those used in shoulder joint replacement, shoulder resurfacing, and shoulder joints or shoulder joints. Other tools used in other operations related to multiple bones including the humeral head. The present disclosure can be applied to anatomical shoulder replacement surgery and reverse shoulder replacement surgery. Patient-specific instruments can 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. A variety of commercially available CAD programs and / or software available, for example, from the Object Research System of Montreal, Canada or ORS can be ...

Abstract

A humeral cut guide member for a humeral head that can comprise: 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 issized and made to substantially mate and nest in only one position with the specific patient's bicipital groove; and a cut guide plate connected to and extending away from the bone-engagement 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 cut guide plate defines an elongated slot.

Description

[0001] Claim priority [0002] This application claims the rights and interests of U.S. Patent Application No. 14 / 750,325 filed on June 25, 2015, and the rights and interests of U.S. Patent Application No. 15 / 073,223 filed on March 17, 2016, thereby claiming these U.S. The priority of the patent applications and these U.S. patent applications are fully incorporated herein by reference. Technical field [0003] The present disclosure relates to a humeral cutting guide member. Background technique [0004] This section provides background information that is not necessarily prior art related to the present disclosure. [0005] During shoulder arthroplasty, the humerus may need to be resurfaced or resected in order to receive shoulder implants. Before surgery, doctors usually obtain multiple images of the surgical area including the humerus via X-ray, CT, ultrasound, MRI, or PET. Based on these images, the doctor can determine the best surgical plan for resurfacing or resection of the...
