The Quadra^® System is based on the experience of the straight, rectangular cementless stem.
The Quadra^® System consists of:

• Quadra^®-S: Cementless stem made of Titanium-Niobium alloy. The surface has a superficial average
  roughness of about 6 µm thanks to a specific sandblasting
  treatment.
• Quadra^®-H: Cementless stem made of Titanium-Niobium alloy. The surface has a 80 μm thick HA coating applied after a superficial sand-blasting.
• Quadra^®-C: Cemented stem made of high nitrogen stainless steel with a mirror polished surface.

Characteristics

• Increased primary stability thanks to the triple taper design.
• Optimal diaphyseal fit.
• 12/14 taper diameter.
• STANDARD and LATERALISED versions.
• Circular section polished neck.
