Improved bone connective prostheses are disclosed. The prostheses comprise a reinforcement element carrying a polymer layer having a varying modulus of elasticity. The exterior surface of the polymer layer constitutes the bone attachment surface of the prostheses and has the lowest modulus of elasticity. The interior surface of the polymer layer is attached to reinforcement element and has the highest modulus of elasticity. Portions of the polymer layer lying between the exterior and the interior surface of the polymer layer have moduli of elasticity which are intermediate with respect to the moduli of elasticity of the exterior and interior surface of the layer The modulus of elas-, ticity …
