Abstract

A hip stem centralizer datum guide and method are provided for positioning a proximal portion of a hip stem component within bone cement in an intramedullary canal of a femur. The datum guide is positionable in a predetermined position relative to the intramedullary canal and is able to create a datum that records the predetermined hip stem component position relative to the intramedullary canal. The datum is able to be referenced to position the hip stem component in the predetermined hip stem component position in the bone cement in the intramedullary canal.
