Abstract
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.
Claims6
A pin of titanium or titanium alloy for cement-free fixing in a long bone to form a prosthesis of a joint or for bone repair, surrounded by a lattice of titanium wire with a mesh size of at least 0.3 mm, wherein said pin and said lattice are coated with a coating of titanium oxide which protects them against long-term corrosion, and said lattice is further coated with an outer coating of a biodegradable and biocompatible material having a low modulus of elasticity and wherein said coating of said biodegradable and biocompatible material extends 0.3 to 1.5 mm beyond the envelope of said lattice thereby protecting said lattice during the fitting of the pin into the bone repair site.
