Paragraph Number

251

In certain embodiments, the positioning guide 780 may be designed and fabricated to be patient-specific. The patient-specific aspects can include a patient-specific bone engagement surface, a predefined angle for reorienting one or more bone or bone parts within one or more planes, a predefined position for bone attachment features 724 or fasteners 710, a predefined or patient-specific offset or amount of translation that is provided, or the like. Alternatively, or in addition, the positioning guide 780 may be selected from a kit, collection, or repository of a number of positioning guides 780: each having a different configuration for one or more aspects/attributes of the positioning guide 780. For example, each member of the repository/kit may include a different positioning angle (repositioning or correction angle), the angles may differ by 2 degrees for example. In such an embodiment, each positioning guide 780 may not be patient-specific to a particular patient but may provide the desired amount of positioning to meet the goals of the surgeon. In certain embodiments, a preoperative plan generated based on the present disclosure may include a recommendation for the positioning guide 780 to be used, even if the recommended positioning guide 780 is not patient-specific to the particular patient.
