Abstract

Modeling in vivo (on Wistar rats) was carried out by the method of complete integration of the prosthesis of an amputated extremity with a residuum; in this procedure the prosthesis is fixed to the residuum with a metal pylon one end of which is implanted into the bone of the residuum, while the other end traverses the residuum tissues and skin 5-7 cm above the residuum surface. This procedure includes not only successful implantation in the residuum bone, but also the possibility that the pores in the metal pylon can be filled with skin cells in the area of the pylon which traverses the tissues of the residiuum. The porous titanium pylon was implanted into the bone of experimental animals with amputated extremities. Penetration of bone and skin cells into the pores of the studied material was demonstrated, which provides tighter fixation in the bone and shows promise for the development of a natural cutaneous barrier to infection.
