Abstract
An alignable orthopedic prosthesis system includes a prosthesis and an alignment guide. The prosthesis includes a stem having at least one slot extending along its length. The alignment guide has an alignment body with a guide surface extending from an end thereof, namely a key element formed as a blade for engaging and guiding the slot to orient the prosthesis stem. The alignment body also fits against a machined bone surface so that the blade is positioned in a plane that is oriented to guide the stem smoothly into contact with a recess formed in the bone.
