Abstract
Methods of designing and manufacturing a number of low-profile metallic customized, patient-specific orthopaedic surgical instruments are disclosed.
Claims1
A method of designing a customized patient-specific orthopaedic surgical instrument, the method comprising:
- defining an outer boundary of a customized patient-specific surgical instrument on a three-dimensional model of a patient's bone generated from patient-specific data, and
- generating a customized patient-specific surgical instrument model within the outer boundary, wherein generating the customized patient-specific surgical instrument model comprises:
- (i) generating a customized patient-specific bone facing surface of the customized patient-specific surgical instrument,
- (ii) generating an outer surface of the customized patient-specific surgical instrument opposite the bone-facing surface,
- (iii) extending a guide body outward from the outer surface of the customized patient-specific surgical instrument model to a free end, and
- (iv) defining a guide slot in the guide body, the guide slot being sized and shaped to guide a surgical tool into engagement with the patient's bone.
