Abstract: A bone press includes a base; a compression plate located opposite to the base; a housing that extends between the base and the compression plate, the housing extending along a longitudinal axis of the bone press; a pressing zone within the housing and between the base and the compression plate along the longitudinal axis of the bone press; and an actuator to provide relative movement between the compression plate and the base to create compression in the pressing zone.

Abstract: Joint prosthesis methods and apparatuses are provided. A bone graft blank is placed in the chamber of the bone press facing a contoured surface. The contoured surface can be part of the bone press or can comprise a surface of a patient specific negative that can be inserted into the bone press. A bone contact surface of the bone graft blank is disposed in the chamber to face the contoured surface of the patient specific insert negative. The bone contact surface of the bone graft blank is compressed against the contoured surface. The bone contact surface can be reshaped to form a patient specific bone graft.
