The Costa-stem is a modern triple-tapered straight-stem made of a highly biocompatible forged titanium-niobium-alloy, which`s shape has been optimized according to biometric findings.
Among new findings, the since 25 years clinically proven concept of a cementless anchorage combined with metaphyseal load transmission has been integrated in the design of the Costa-stem in order to realize an innovative product.
Two offset versions allow an anatomically adapted reconstruction and therewith a preciser adjustment of lever arms and muscle forces.
Overall the Costa-stem is available in 20 sizes (10 x standard, 10 x lateralized), which makes an adequate treatment of different femur sizes possible.
The mentioned features are the link between the classic anchorage principle and the latest findings in total hip arthroplasty.
