VerSys® Hip System Enhanced Taper
The benefits of a taper design are well recognized, particularly in the
European orthopaedic community.1, 2, 3 A collarless, trapezoidal
proximal body is designed to provide secure primary fixation and rotational
stability, while the corundumized surface finish enhances fixation.4 The
collarless design, combined with a narrow distal taper, provides increased
flexibility in implant sizing to achieve optimum proximal fixation.
Anterior/Posterior and lateral fins, verified with ANADAT* data are designed to engage the cancellous bone at the cortico-cancellous junction to achieve secure initial fixation and provide exceptional rotational stability.1, 3
Femoral Heads and Acetabular Components
Zimmer offers a full complement of femoral heads and acetabular components.
*An essential foundation for the VerSys Hip System was the ANADAT® Anatomical Data Base, comprising details anatomic measurements of cadaver femora that guided implant sizing and design. Utilizing ANADAT data, VerSys Designers built a stem designed upon the proven strengths of the taper concept, incorporating proximal fins to enhance primary fixation and stability.
