Research Facts
This type of prosthesis would have been used for a patient who had already had a prosthesis that had loosened and needed to be replaced; an engineer and two orthopedic surgeons first developed beads on metal in 1970; Howmedica developed a 400 µ ball P.C.A. (Porus Coated Anatomic) system; this system is modular and has detachable femoral head parts; Dr. Charles Sorbie was one of the trialists for North America for this system; the purpose of the beads is for bone to grow around the prosthesis after it is implanted.
