Design Rationale Key Points
|
Many important factors were considered in the design of the Durom Femoral Component; bone conservation, precise positioning and an optimum cementing technique were of utmost importance. The slim-line stem requires less bone removal than comparable systems, permits ideal positioning and allows for an even cement mantle. The unique recesses on the inner side of the component allow controlled pressurization of cement into the cancellous bone and provide rotational stability. |

- 12 sizes are available in 2mm increments from 38 to 60mm diameters.
- Articulating surface component is made of high carbon CoCr Metasul ® Alloy. A forging process is used which reduces the block carbide size about eight times, resulting in lower surface roughness compared with cast alloys.
- The femoral stem has no fixation function therefore a fit to the canal is avoided. This allows for transfer of force to the femoral head reducing stress shielding.
- The unique recesses on the inner side of the component allow controlled pressurization of cement into cancellous bone and function later as antirotational features.
