摘要:
The utility model is aimed at shortening the postoperative healing due to high primary stability and early functional load on the joint in the early period after surgery, reducing pain, subsequent effective rehabilitation. The endoprosthesis of the interphalangeal joints of the fingers comprises a distal articular cup and the proximal articular head with legs. The novelty of the claimed endoprosthesis mezhfatsangovyh joints of fingers is that the distal articular leg has the shape of a truncated cone with an apex angle of 11-13 degrees, the height of the distal articular legs of 7,0-12,0 mm, the lower base of the distal articular legs adapted diameter d1, equal to 3,1-4,7 mm, from the lower base leg distal articular head has a diameter d1 equal to 5,2-6,8 mm and 0,5-0,8 mm thick proximal articular leg has the shape truncated cone with an apex angle of 5-7 degrees, the height of about maximum DUTY articular legs of 9,0-13,0 mm, the lower base of the proximal articular legs formed with a diameter d2, equal to 3.0-3.6 mm, from the lower base leg proximal articular head has a diameter D2, equal 5,1- 5.7 mm and 0.5-0.8 mm thickness, proximal and distal joint legs are centered blind bore, wherein the first 1-3 mm holes have a square cross section with sides of 1.5-2.0 mm, more holes are circular cross section with a diameter of 1.5-2.0 mm, the total depth of holes h is 2.0-4.0 mm, the hinge comprises a flexible portion and two pins that are built into the flexible part of the hinge with the ability to install them in the non-through holes distal and proximal articular legs, pins dimensions correspond to the dimensions of non-through holes in the proximal and distal joint legs, the flexible part of the hinge has a flat surface located on the rear side of the hinge, and a concave surface , located on the palm side of the pivot, the concave arcuate surface has a recess shape, and two stopper at the edges of the external dimensions of the flexible hinge portion represents t a
