1. A device for use in placing a prosthesis in a patient during joint replacement surgery, the device comprising:
a first component formed using medical imaging data corresponding to an anatomic structure of the patient and a final installation position of the prosthesis such that a surface of the first component is configured to nestingly mate with a first portion of the anatomic structure of the patient in a single orientation; and a second component formed using the medical imaging data corresponding a second portion of the anatomic structure of the patient and the final installation position of the prosthesis; the first component having a first body, the first body extending between a lower surface and an upper surface, having an aperture extending therethrough, and having an anatomic alignment member extending outward from an outer surface of the first body, the anatomic alignment member having a first alignment surface shaped to conform to the anatomic structure of the patient, the aperture defining a longitudinal axis and being at least partially defined by an inner surface extending between the upper surface and lower surface, the inner surface sized and shaped to receive the second component, the second component including an upper portion and a lower portion, the upper portion joined to the lower portion at an alignment rim sized and shaped to mate with a rim of the prosthesis, the lower portion having a surface sized and shaped to conform to at least part of an internal working surface of the prosthesis, the upper portion of the second component having an upper surface, the upper surface of the second component being movable along the longitudinal axis and relative to the upper surface of the first component, the upper surface of the second component and the upper corresponding to a final installation position of the prosthesis to be secured to the anatomic structure of the patient according to the medical imaging data. |
