PERCUTANEOUS PROSTHESIS Russian patent published in 2010 - IPC A61F2/28 

FIELD: medicine.

SUBSTANCE: percutaneous prosthesis comprises a first component profiled to be implanted in a bone, a second component designed to be placed between the bone and skin, and a third component adapted designed to be placed outside on the skin surface. A surface of the second component processed for fibroblast proliferation stimulation and epitheliocyte attachment is specified in the group consisting of a porous surface or a mictopit surface wherein the micropits have a size of about 20 to 500 microns, and having an external coating of a material chosen from hydrated calcium phosphate, promoting adhesion of proteins and alumina ceramics. The third component is passable directly outside or through skin and has an external surface having a non-adherent material and thereby having low surface energy for bacteria adhesion prevention.

EFFECT: invention provides transosseous load transmission, which means that a patient is able to apply much more force to a prosthesis, ensured more natural motion and motion perception in view of the bone attachment, besides, since the skin is not involved in load transmission between the bone and an external part of the prosthesis, there is no pressure upon the skin surface that otherwise could cause inflammation and discomfort.
