摘要：
Disclosed are embodiments of an improved joint prosthesis that can provide the option to improve initial stability without removing the implant or altering the preparation. Embodiments of improved joint implant components can comprise one or more expandable, hollow segmented posts. Methods of implant fixation are also disclosed. Disclosed methods can provide the opportunity for establishing initial biologic fixation (bone ingrowth), and can also provide an adjunct fixation through injecting cement down the center of the post if initial stability is not achieved or is questionable.
