Embodiment Construction

[0028] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0029] The present disclosure generally provides a patient-specific surgical instrument, for example, including alignment guides, drill guides, and other tools used in shoulder arthroplasty, shoulder resurfacing, and other procedures that Procedures are operations related to the shoulder joint or the bones of the shoulder joint, including the humeral head. The present disclosure is applicable to anatomical shoulder replacement and reverse shoulder replacement or resurfacing. The present patient-specific instruments may be used with conventional implant components, or with patient-specific implant components and / or bone implants prepared using computer-aided imaging methods according to the present disclosure. 3D images of patient anatomy using computer modeling of medical scans of patient anatomy (e.g., MRI, CT, ultrasound, X-ray, PET, etc.), patient-specific prosthetic ...

Abstract

Humeral Cutting Guide System for resection or resurfacing of the humeral head. The humeral cutting guide system includes a primary cutting guide member configured to be removably engaged to the humeral head. The primary cutting guide member includes a patient-specific bone-engaging surface, a primary elongated slot defining a primary cutting surface, and a pair of cylindrical apertures configured to receive a pair of guide pins. The auxiliary cutting guide member includes a pair of through holes configured to mate with the pair of guide pins, and the auxiliary cutting guide member includes an auxiliary elongated slot defining an auxiliary cutting surface.

Description

technical field [0001] The present invention relates to a humeral cutting guide member. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] In shoulder arthroplasty, the humeral bone may require resurfacing or resection to receive the shoulder implant. Before surgery, doctors typically take multiple images of the surgical area, including the upper arm bone, by X-ray, CT, ultrasound, MRI, or PET. Based on these images, physicians are able to determine the best course of action for resurfacing or resection of the upper arm bone, as well as determine whether the primary surgical procedure for shoulder repair is anatomical or anatomical reverse arthroplasty. During surgery, however, it is more common for the physician to determine that the preselected course of action is not appropriate for the patient. If the course of action is changed during the procedure, new instruments ...
