Novation® CFS™ Press-Fit

The Novation® CFS™ Femoral Stems are designed to provide surgeons with excellent initial fixation and long-term stability when paired with the core instruments that support Novation Tapered and Splined preparation. This allows for simple preparation and ease of intra-operative transition to a low-demand stem should the need arise.

Novation CFS Universal Features

1. Cobalt Chrome and Ziramic™ Zirconia 12/14 femoral heads in varying sizes provide optimal range of motion and enhanced intra-operative flexibility
2. 131-degree neck angle designed to predictably restore normal anatomy
3. Neck cross-section is minimized on the medial aspect to increase range of motion, decreasing the chance of post-operative dislocation, while material on the lateral side is maintained for strength
4. Available in Collared (Standard Offset) only.

Novation CFS Press-Fit (Sizes 9-18mm)

5. Grit blast titanium surface provides bone on-growth and long-term stem stability¹
6. Trapezoidal cross-section to provide rotational stability, proximal fit and A/P fill²
7. Shortened overall length, with 3-degree taper in the M/L and a 5-degree taper in the A/P plane, allowing for three-point fixation
8. Patented distal tip design reduces stress concentration at the distal stem and bone interface, which has been shown to reduce the incidence of thigh pain.^3,4
