Cementless femoral stem Alteon® HA

The design philosophy of the Alteon® HA Femoral Stem evolved from more than 25 years of clinical use. It features incremental stem sizing, proportional neck geometry, and reduced stem lengths, yet adheres to the core design principles of the philosophy. This system is designed to be bone conserving, while providing initial stability to promote biologic fixation. Surgeons are afforded a simple broach-only technique that offers flexibility to accommodate various surgical approaches. Incremental Sizing Neck Four neck length groupings and two offsets provide multiple options to restore patient anatomy without the need for neck modularity. Stem Intentionally grows at a smaller rate medially to laterally when compared to other stems. This proportional growth of the implant body addresses a wide variety of patient anatomies. Reduced Overall Length Reduced Stem Lengths Overall stem lengths are reduced up to 25 percent versus competitive designs in order to preserve more bone and accommodate a variety of surgical approaches.
