Abstract

System, devices, and methods for orienting a guide block with a patient's anatomy are provided. A two-piece guide block is configured to couple with a patient's femoral head and femoral neck to align a guide passage along a desired axis that extends through the femoral head. The guide block is patient-matched to match surface features of the patient's femoral head and femoral neck to provide a stable mating interaction. An interior surface of the two- piece guide block includes a cutting element that extends radially inward to mate with the femoral neck. The cutting element allows the block to mate with a femoral neck that is surrounded by cartilage or other soft tissue. The cutting element maintains a close mating interface with the femoral neck without requiring extensive damage or removal of the surrounding cartilage and tissue.
