PERFECCIONAMIENTOS EN CANAS DE TITANIO O ALEACION DE TITANIO PARA FIJACION SIN CEMENTO EN UN HUESO LARGO PARA PROTESIS.

摘要

A titanium or titanium alloy pin for cement-free fixing in a long bone for a joint prosthesis or for bone repair is surrounded by a lattice of titanium wire with a mesh size of at least 0.3 mm. The central part of the pin and the lattice are coated with a coating of titanium oxide which protects them against long-term corrosion. The lattice is further coated with a biodegradable and biocompatible material having a low modulus of elasticity.
