Abstract
A surgical prosthetic device or implant is disclosed consisting of a coherent metal substrate and a pure metal porous coating. The pure metal porous coating is formed by thermal decomposition of a coating of thermally-decomposable metal compound particles and sintering of the metal particles so formed. The surface of the device or implant is irregular but the porosity is substantially uniformly distributed throughout the coating. The coating is strongly adherent to the substrate and supports the ingrowth of bone tissue for fixation of the device or implant in the body. Such coating also supports the ingrowth of fibrous tissue for the attachment of tendons and ligaments to the device.
