Abstract

A device for prosthetic restoration of human limbs comprises a supporting member for the stump, shaped as a spherical bowl and connected to the prosthesis of the limb missing portion, and a fixing contrivance interconnecting the stump bone and the supporting member. The supporting member is made of a material indifferent to living tissue and its diameter corresponds to the stump outside diameter. The outer surface of the supporting member is made of a porous material which promotes implantation of living tissue therein, while its top base serves as a support for the stump bone and muscles.

A method for prosthetic restoration of human limbs consists in joining the supporting member to the stump bone, followed by wrapping up of the supporting member by the stump skin, whereupon a suture is applied along the arc of the spherical base of the supporting member; after a period of time has elapsed, necessary for the supporting member to implant, a fistula is established in the spherical base of the member and the latter is connected to the prosthesis of the limb missing portion.

The present invention is applicable, in particular, for prosthetic restoration of the lower and upper limbs of disabled persons, which have been amputated at any level, as well as in cases of vasculopathies and diabetes mellitus.

Claims

1. A method for prosthetic restoration of a human limb having a stump, consisting in joining a supporting member shaped as a spherical bowl, to a stump bone, said supporting member being made of a material indifferent to living tissue, while its diameter corresponds to the outside diameter of said stump;

said supporting member having a coating made of a porous material, which promotes implantation of living tissue therein, and a top base of said supporting member serving as a support for bone and muscles of said stump;

once said joining of said stump bone and said supporting member has been carried out, said supporting member is wrapped up completely in skin of the stump and a suture is applied along an arc of the spherical bowl of said supporting member, and after a period of time has elapsed, necessary for said supporting member to implant, a fistula is established in the skin of the stump within a zone of the spherical bowl of the supporting member to expose connection means of said supporting member and said connection means is connected to a prosthesis of a missing limb portion.
