1. A method for manufacturing a patient-specific jig for use in confirming a correct contour of a fixation element in an operative setting, the method comprising the steps of:
accessing a data file containing patient-specific geometric parameters associated with a modeled patient-specific anatomical correction of a native anatomy of a particular patient based on a patient-specific pre-operative plan for the particular patient;
obtaining one or more fixation element design criteria based at least in part on one or more reference patient data sets, wherein the reference patient data sets include data from patients other than the particular patient;
designing the patient-specific jig to include a patient-specific contoured curve based on the patient-specific geometric parameters and the one or more fixation element design criteria;
converting the patient-specific jig design into a machine data set for use by a three-dimensional production machine; and
sending the machine data set to the three-dimensional production machine upon which the patient-specific jig is produced by the three-dimensional production machine in accordance with the machine data set.
