Paragraph Number

280

Alternatively, a bone engagement feature 928 may be included in the bone tunnel guide 920 to specifically engage with a particular landmark at, or near, a planned position for the bone tunnel guide 920 on the bone. For example, suppose a bone spur extends from a patient’s bone just posterior to a planned position for the bone tunnel guide 920. A user may request (e.g., by way of user instructions 604) that another bone engagement feature 928 be added to the design, a bone engagement feature 928 that extends posteriorly to cover/include/engage with that bone spur. In this manner, certain landmarks and/or landmark configurations can be accounted for and/or used to facilitate the accurate and precise positioning of the bone tunnel guide 920 during a planned surgical procedure. Consequently, a number of bone engagement features 928 included in the bone tunnel guide 920, as well as the size, shape, configuration, position, and/or orientation of each bone engagement feature 928 can be determined at least partially by user instructions 604. For example, a surgeon may request that one bone engagement feature 928 be made wider to provide greater registration with bone surface in that area of the bone during the surgical procedure.
