FIELD: medicine.
SUBSTANCE: structure contains a porous layer based on ultra-high molecular weight polyethylene, also contains a continuous layer based on ultra-high molecular weight polyethylene over the porous layer with a strong boundary between the layers, the structure repeats the bone wall characteristics in accordance with the characteristics of the defective bone region, the porous layer has an open porosity of 50-90 vol. % and a bound pore system with a diameter of 50-1000 mcm.
EFFECT: prevents stratification and separation of particles during mechanical deformation of the structure, provides impact resistance, wear resistance.
