Abstract : The invention is a method of improving orthopedic implant material by the simultaneous electrodeposition of bone particles and an inert plastic binder onto a prosthesis. A polyamic acid is dissolved in a solvent such as dimethylsulfoxide and an amine is added to the solution to produce the organic salt of a free carboxyl group. A colloidal suspension of the organic salt and fine bone particles in a mixed solvent comprised of acetone and dimethylsulfoxide is placed in a receptacle and a voltage is applied to a pair of electrodes immersed in the solution causing the deposition on the anode of bone in a polyamic acid plastic matrix. After subsequent cure, the result is a coating of bone within a polyimide matrix on the electrode.
