Content

The sights 1894 serve to assist a surgeon in reviewing, confirming, and/or validating a position of the first resection guide 1822 relative to other anatomical structures of the patient (e.g., bones). In one embodiment, sights 1894 are used during a surgical procedure and can be used together with medical imaging to check position, alignment, trajectory, or the like. In one embodiment, a surgeon may provisionally position the first resection guide 1822 and then use flouroscopy to visually check or confirm a position of the first resection guide 1822 relative to another bone or other bones of the patient. In certain embodiments, the flouroscopy machine (e.g., C-arm) can include reference features that key off of certain markers or anatomical features of the patient to ensure that the flouroscopy image is the view desired for the surgeon. A surgeon may use the flouroscopy machine and locate a sight 1894 to determine whether or not the first resection guide 1822 is in a desired position. In one embodiment, the flouroscopy machine may include a scope or view finder or corresponding sight (e.g., cross hairs) that a surgeon can align with the sight 1894 to do a visual check and/or confirmation of the position of the first resection guide 1822. After this visual check, a surgeon may secure the first resection guide 1822 to one or more bones of the patient (i.e., deploy pins in bone attachment features 1828).
