Content
In a step 106, the CAD model and/or CT scan data may be used to model patient-specific instrumentation that can be used to correct the condition, as it exists in the patient’s anatomy. In some embodiments, any known CAD program may be used to view and/or manipulate the CAD model and/or CT scan, and generate one or more instruments that are matched specifically to the size and/or shape of the patient’s bone(s). In some embodiments, such instrumentation may include a cutting guide that is attachable to one or more bones, with one or more guide features that facilitate resection of the one or more bones pursuant to a procedure such as arthroplasty or arthrodesis. In some embodiments, performance of the step 106 may include modelling an instrument with a bone apposition surface that is shaped to match the contour of a surface of the bone, such that the bone apposition surface can lie directly on the corresponding contour.
