Abstract
There is disclosed a prosthesis comprising a prosthetic element and a polymethylmethacrylate film fixedly adhered thereto. The prosthesis comprises a surface adapted to be fixedly attached to bone and bears a polymethylmethacrylate film upon the attachment surface. The polymethylmethacrylate film is adhered to the prosthetic element by a process which comprises treating the prosthetic element surface to eliminate any weak boundary layer, applying polymethylmethacrylate to the treated surface, and thereafter annealing the polymethylmethacrylate film.
Claims23
A process comprising joining a prosthesis to bone by applying bone cement to a polymethylmethacrylate film fixedly adhered to a prosthetic element, said prosthesis having been prepared by the steps of:
- treating said prosthetic element to eliminate any weak boundary layer;
- applying polymethylmethacrylate to said treated surface to form a film thereon;
- and thereafter annealing said polymethylmethacrylate film.
