VerSys Advocate™ Hip Prosthesis

Influenced by traditional stem design and long-term clinical experience, the VerSys Advocate Hip Prosthesis offers a solid foundation for success. Distinctive centralizer options help the physician to accurately position the stem proximally and distally. In addition, the satin finish, consistent with traditional stems, has proven successful in long-term clinical studies. 1

Distal Centralizer

A "5-point-star" design configuration helps improve cortical diaphyseal contact and stem alignment, compared with four-prong distal centralizers. 		VerSys Advocate

Integrated Metal V-Lign® Proximal Centralizer

V-Shaped machined grooves in the calcar surface assist in positioning of the implant within the canal.

Helps achieve a uniform proximal cement mantle through accurate M/L and A/P alignment.

VerSys Advocate

Flat Back Design

Clinical studies have shown that cemented stems with circular cross-section have less torsional resistance, leading to potential debonding at the implant/cement interface.3

The rectangular cross-section geometry of the VerSys Advocate hip prosthesis helps provide rotational stability within the cement mantle.

Satin Finish

Forged, high strength ZimaloyÒ Chromium-Molybdenum Alloy is consistent with traditional stems and has proven successful in long-term clinical studies.2
