Self-Centering Hip Stem Addresses Surgeons' Needs

A new hip prosthesis device is designed to ensure that an implant is properly centered in the femoral canal.

Cemented hip replacements need proper centering and the VerSys Advocate Hip will aid surgeons who prefer to use cemented products. The Advocate Hip's design provides control for anterior/posterior and medial/lateral positioning, as well as for rotational stability. "Surgeons have told us that one of the keys to long-term success for cemented hip replacements is the ability to assure that the implant is properly centered in the femoral canal,” said Ray Elliott, chairman, president, and CEO of Zimmer Holdings, Inc. (Warsaw, IN, USA). The hip stem incorporates Zimmer's Proximal Centralizer. The company says the cemented hip category is the largest in hip replacement.

"I think it will also be adopted in many teaching institutions because orthopedic surgeons in training will find it helpful in learning how to properly place the hip implant in the femoral canal,” said Dr. Richard White, who participated in the product's design with Zimmer.
