Augment for plastic surgery of marginal bone defects in knee arthroplasty

摘要

The utility model relates to the field of medicine, namely to implants. The augment is made in the form of a block having the shape of a trapezoidal polyhedron with sharp ribs, two parallel bases of the type of the upper and lower platforms, four lateral - the two most extended longitudinal and two multidirectional inclined faces. The polyhedron from the side of one of its longitudinal side faces is beveled at an angle to the longitudinal axis of the block. From the side of the outer surface of the bases and two inclined faces, protrusions are equally spaced from each other. The use of a universal augment will make it possible to form a landing surface for femoral components of various types of knee joint endoprostheses produced by a wide range of manufacturers, increasing the stability and strength of their fixation by increasing the adhesion force and the area of contact between bone cement and the outer surface of the augment. 1 s.p. f-ly, 1 ave., 3 ill.
