Prosthetic stem with cement sleeve

Abstract

An artificial joint is capable of harmoniously connecting the artificial joint, cement and a bone and facilitating effusion of the cement at the time of implantation, as well as diminishing the stress applied thereto. The artificial joint includes a head, a neck and a stem, the stem being coated in advance with cement so as to easily bond the cement to cement filled in a bone cavity of a human femur. An effusion path for effusing the cement filled in the bone cavity is formed in a longitudinal direction on a surface of the cement coated on the stem so that the cement filled in the bone cavity of the human femur can be easily effused upward through the effusion path when the stem is inserted.
