ABSTRACT:
A centralizer for the stem of a cementable prosthetic orthopedic implant that is implanted into the medullary canal of a bone has a hollow annular body with a tapered interior surface for receiving a tapered stem of the implant. The centralizer has four fins spaced around the exterior surface of its annular body with the fins extending radially outwardly in a direction generally perpendicular to the longitudinal axis extending along the stem in a proximal-distal direction. The annular body of the centralizer has a proximal and a distal end surface spaced a predetermined distance apart with the fins having a base adjacent the body extending over a substantial portion of the predetermined distance. Adjacent fins are offset from neighboring fins in a proximal-distal direction so that when the proximal-distal dimension of the annular body is maintained, it generates a wavelike structure for the centralizer body.
