Details of a procedure for electrolytically preparing highly pure brushite (CaHPO, . 2H,O) coatings on high surface area metal substrates are provided. The influence of current density and deposition time on coating morphology is described. After a discussion of procedures used to convert the brushite coatings to hydroxyapatite, results from a preliminary animal study that demonstrate the propensity of these coatings to stimulate bony ingrowth into porous plugs are presented.
