Proximal conical stem
摘要:
A cementless femoral hip stem component includes an elongate stem having opposing distal and proximal sections. The proximal section includes a conical stem surface which terminates in a proximal end. A collar having a conical undersurface extends laterally outward from the proximal end of the stem. The proximal conical stem portion and the conical undersurface of the collar cooperatively define a unitary double-cone contact surface to allow the collar to subsidably engage with external cortical bone in tandem with the proximal conical stem subsidably engaging with the internal femoral canal.
