Abstract
A femoral head press can comprise: a frame having first end second ends; a clamp connected to the first end to define a holding plane; a mechanical drive mechanism mounted to the second end and having a drive axis; a ram connected to the second end; and a femoral head cup connected to the ram; wherein the mechanical drive mechanism is configured to drive the ram along the drive axis substantially perpendicular to the holding plane to advance the femoral head cup toward the clamp. A method for assembly a femoral head to a stem neck can comprise: attaching a clamp of a frame of a femoral head press to a neck of a femoral stem; connecting a femoral head to a cup connected to a ram slidably engaged with the frame; and actuating a mechanical drive mechanism coupled to the frame to advance the cup toward the neck.
