Paragraph Number

77

In a step 126, the CAD model and/or CT scan data may be used to model patient-specific instrumentation that can be used to correct or remediate a bone condition. Such instrumentation may include a guide. In one example, the guide can seat or abut or contact a surface of a bone and including an opening that guides a trajectory for a fastener for a procedure. In some embodiments, performance of the step 126 may include modelling the guide with a bone engagement surface that is shaped to match contours of the surfaces of the bone, such that the bone engagement surface can lie directly on the corresponding contours of the bone.
