Abstract:
1. A method of guiding resection of a patient tissue and guiding placement of a prosthetic implant component in a desired implant position with respect to the resected patient tissue, the method comprising the steps of: placing a mating surface of a locating block in mating contact with the patient tissue, the mating surface being custom-configured for the patient tissue responsive to pre-operative imaging of the patient tissue to allow a single locating block mating orientation relative to the patient tissue; providing a physical indication of a desired cutting plane for the resection using a cutting plane indicator included on the locating block; providing a placement indicator, spaced apart from the locating block and including a component-contacting feature; spacing the placement indicator apart from the locating block with an elongate spacing arm, the spacing arm having oppositely disposed first and second spacing arm ends, the first spacing arm end being attached to the locating block and the second spacing arm end being attached to the placement indicator; placing the component-contacting feature of the placement indicator at a predetermined placement position in three-dimensional space relative to the patient tissue with the spacing arm, the placement position predetermination being at least partially based upon pre-operative imaging of the patient tissue; guiding a cutting implement with the cutting plane indicator to resect the patient tissue along the desired cutting plane when the mating surface is in mating contact with the patient tissue; placing the prosthetic implant component in an initial implant position with respect to the patient tissue; adjusting the prosthetic implant component with respect to the patient tissue to bring the prosthetic implant component toward a desired implant position; and bringing a preselected surface of the prosthetic implant component into contact with the component-contacting feature to indicate that the prosthetic implant component has achieved the desired implant position.
