摘要：
The aim of said proximal interphalangeal joint of the fingers of the endoprosthesis is to eliminate inflammation due to possible detachment of the collateral ligaments by increasing the lateral stability of the prosthesis.This object is achieved by a proximal interphalangeal joint endoprosthesis fingers having distal and proximal articular legs connected by bending unit (hinge).The novelty of the claimed endoprosthesis interphalangeal joints of the fingers is that the proximal articular foot is in the form of a truncated cone with an angle equal to 03.05 degrees, the length L1 of the proximal articular legs of 10.0-15.0 mm, the diameter d1 is 2.8 -3.2 mm from the lower base of the proximal articular leg hat has a thickness of 0.6-0.8 mm and a rim, the width of which is 0.9-1.1 mm proximal articular leg also has a conical blind bore , which angle is 3-5 degrees, and Ch Ubin I1 is 4.0-5.0 mm, in addition, from the lower base of the proximal joint section legs formed at an angle of 20 degrees, passing through the rotation axis of the cone of the proximal articular legs distal articular foot is in the form of a truncated cone whose angle is 11-13 degrees, the length L2 of the distal articular legs of 8,0-14,0 mm, the diameter d2 is 2.1-2.8 mm, the distal articular leg has a hat, wherein a thickness of 0.6-0.8 mm and a rim, the width of which is 0.9-1.1 mm, the distal articular leg also has a conical blind bore, which angle is 6 degrees, and I2 is the depth of 4,0-5 0 mm folding unit consists of a flexible part and two pins, which are embedded in the flexible part, the dimensions of pins correspond to the dimensions of openings in the proximal and distal joint legs, respectively bending modulus in basis has a parallelepiped shape with height H, component 7,0-10,0 mm, a width X, component of 6.0-9.5 mm and a depth G, component 8,0-11,0 mm, on the one hand bending unit has a wedge-shaped groove with an angle of 60 degrees on the other side of the bending unit has a recess
