Abstract
A pre-operative planning and manufacturing method for orthopedic surgery includes obtaining pre-operative medical image data representing a joint portion of a patient. The method also includes constructing a three-dimensional digital model of the joint portion and manufacturing a patient-specific alignment guide for the joint portion from the three-dimensional digital model of the joint portion when the image data is sufficient to construct the three-dimensional digital model of the joint portion. The patient-specific alignment guide has a three-dimensional patient-specific surface pre-operatively configured to nest and closely conform to a corresponding surface of the joint portion of the patient in only one position relative to the joint portion. The method further includes determining, from the image data, a size of a non-custom implant to be implanted in the patient and manufacturing the non-custom implant when there is insufficient image data to construct the patient-specific alignment guide therefrom.
