Abstract
A method for pre-operative orthopedic planning includes obtaining only a high-resolution knee-joint scan of a patient, determining hip rotation center and ankle rotation center from anthropometric data based on personal data of the patient, and determining a mechanical axis of the knee joint based on the anthropometric data. The method also includes preparing at least a two-dimensional image model of the knee joint using the knee-joint scan and the determined mechanical axis, and preparing a pre-operative surgical plan based on the image of the knee joint.
Claims20
A method for pre-operative orthopedic planning comprising:
- obtaining only a high-resolution knee-joint scan of a patient;
- determining hip rotation center and ankle rotation center from anthropometric data based on personal data of the patient;
- determining a mechanical axis of the knee joint based on the anthropometric data;
- preparing at least a two-dimensional image model of the knee joint using the knee-joint scan and the determined mechanical axis;
- and
- preparing a pre-operative surgical plan based on the image of the knee joint.
A method for pre-operative orthopedic planning comprising:
- obtaining only a high-resolution knee-joint scan of a patient;
- taking a digital photographic image of the patient;
- determining a hip rotation center and an ankle rotation center from the digital photographic image;
- determining a mechanical axis of the knee joint based on the knee-joint scan and the hip rotation center and ankle rotation center;
- preparing an at least two-dimensional image model of the knee joint using the knee-joint scan and the determined mechanical axis;
- and
- preparing a pre-operative surgical plan based on the image model of the knee joint.
A method for pre-operative orthopedic planning comprising:
- creating a diseased bone database;
- obtaining personal data of a patient;
- selecting a best-fit bone model from the diseased bone database based on the personal data of the patient;
- transforming the best fit model to a customized model matching the personal data of the patient;
- and
- preparing a pre-operative surgical plan based on the customized model without obtaining image data of the patient.
