Alteon® Highly Polished Stem

The Alteon® Highly Polished Stem is a highly polished cobalt chrome cemented stem which fits within the Alteon® HA broach cavity. The highly polished surface of this stem is designed to reduce the amount of wear particles.1,2 This stem also features incremental stem sizing, proportional neck geometry, and uses all of the Alteon® platform instrumentation.

French Paradox Cement Technique

  • The Highly Polished stem is used in conjunction with a thin cement mantle which provides direct cortical bone contact in some areas. This type of technique allows for a canal filling implant to be used and is designed to transfer the load from the stem to the bone.3

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.4

Platform Instrumentation

Scope

    • Standard Offset Sizes 4, 6, 8, 10, 12
    • Extended Offset Sizes 4, 6, 8, 10, 12
