摘要：
An implant includes a head portion, an intermediate portion and an initially separate stem portion configured to engage the head portion so that at least the head portion and the stem portion cooperatively secure the intermediate portion on the implant. The implant may also include a locking mechanism configured to secure the head portion to the stem portion by a press fit or a threaded connection. The intermediate portion may include a porous metal such as tantalum.
