The Femoral Component

Innovative

The femoral component has a unique set of properties. The slim femoral stem allows precise positioning and the recesses offer an optimal cementing technique. Impaction of the femoral head is not required during location and the action of seating the head pressurises the cement and leads to an average 3.2mm penetration into the femoral head*(1).

Unique

The femoral stem is designed such that it transfers no stress to the bone and therefore all stress is passed through the outer femoral head leading to improved stress distribution within the femoral head. The design of the Durom femoral component leads to a pre-defined cement mantle of 0.75mm and sufficient cement penetration to provide good bonding of the implant to the bone, but not so much as to lead to high stress regions within the femoral head. These design features should lead to improved survivorship of the femoral component.

Smooth

The wrought-forged, high carbon CoCr Metasul alloy offers considerable tribological advantages over cast CoCr alloys. Wrought-forged CoCr is harder than cast CoCr and demonstrates excellent wear resistance.  Wrought-forged can also be more highly polished than cast CoCr, reducing surface roughness and enhancing lubrication. The wrought-forged Metasul alloy has been in successful clinical use since 1988 and remains the material of choice for metal on metal bearings.

Preserves

The Durom femoral component is available in 2mm increments from 38 to 60mm outer diameter to allow for precise sizing of the femoral component and more accurate matching of the femoral size to that of the reamed acetabulum.
