Paragraph Number

268

In certain embodiments, a user, or end user, may review the bone model, and a model of the bone tunnel guide 920 and based on these models determine, at least in part, where to position and/or orient a trajectory port 924 within a bone tunnel guide 920. Advantageously, determining a position and/or orientation for the trajectory port 924 in a model of an instrument can be directly reflected in a fabricated instrument based on the model. In one embodiment, the position and/or orientation for the trajectory port 924 can be based on user instructions 604. Alternatively, or in addition, other features of a trajectory port 924 can be based, at least partially, on user instructions 604. Alternatively, or in addition, in one embodiment, features of a bone tunnel guide 920 can be based on accepted practice aspects for a particular surgical procedure.
