Functional description

The modular vitelene insert is made of highly cross-linked polyethylene stabilised with vitamin E which provides long term oxidation protection. The inserts are conically clamped in the cup. On the underside of the vitelene there is a prop which is designed to support the inlay lower cup edge when its fully countersunk in the core. The liners with posterior wall (hooded) increase luxation stability. The asymmetrical liners correct the cup position by 10 degrees.
