Abstract
A method of preoperative planning and provision of patient-specific surgical aids includes creating a virtual model of a native patient tissue. A virtual device is placed into a predetermined device orientation relative to the virtual model of the native patient tissue. At least one predetermined landmark orientation is specified for placement of at least one virtual landmark relative to the native patient tissue. A virtual patient-specific template containing the predetermined landmark orientation and having a landmark guiding feature is generated. At least one virtual patient-specific placement guide configured to interact simultaneously with at least one previously placed virtual landmark and the virtual device when the virtual device is in the predetermined device orientation is generated. A physical patient-specific template is created as a tangible representation of the virtual patient-specific template. A physical patient-specific placement guide is created as a tangible representation of the virtual patient-specific placement guide.
