VerSys® Heritage® Hip Prosthesis
The low-friction hip prostheses developed by Sir John Charnley has a 20-year history of outstanding results.1 The VerSys Heritage Hip Prosthesis preserves the stem geometry and polished surface characteristics of that first-generation prosthesis. Building on this successful concept, Zimmer has incorporated additional features designed to enhance implant performance.
Extended Offset
Options are possible because of a parallel medial neck shift that does not
change the stem's 135-degree neck angle or increase leg length.2, 3
Optional VerSys Heritage Proximal Sleeve Centralizer
Helps the surgeon achieve a uniform cement mantle by neutral positioning of the femoral component. Two recesses in the proximal body help position the centralizer on the stem.
