Abstract

Patient-matched devices according to certain embodiments may include a patient-matched surface that generally conforms to a portion of the patient's anatomy, and an alignment mechanism that is positioned at a fixed orientation with respect to the patient-matched surface. In some embodiments, the alignment mechanism is an alignment post extending away from the patient-matched surface along a predetermined axis. This axis may be pre-operatively determined to correspond to (or at least indirectly reflect) the proper orientation of surgical instruments and/or implants that are used in the surgery. An alignment base and platform may selectively couple to the patient-matched device and other instruments (such as a reamer or an impactor). The surgeon may use alignment indicators on the alignment platform to ensure that the proper orientation is maintained throughout the surgery.
