摘要：
The object of the present interphalangeal prosthesis 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 interphalangeal endoprosthesis having a proximal articular head to foot and distal articular cup with stalk.The novelty of the claimed interphalangeal prosthesis is that the proximal articular head has a recess and the distal articular cup has a protrusion furthermore proximal articular head has a cylindrical work surface with an outer radius R1 constituting 2.5-5.5 mm, whose center is on the symmetry axis passing through the center leg, in a section proximal articular head is in the shape of a square has a width B1, component 5,5-12,5 mm, H1 and a height of 4.5-9.0 mm in the proximal joint of ovke a recess with a depth h1, component 0,9-1,5 mm and the width b1, component 1.0-2.5 mm, which extends transversely to the cylindrical working surface in a circle, the leg proximal articular head has an oval tapered shape, in which horizontal section is formed with a cone angle of 5-7 degrees, and the vertical - 1-3 degrees and is inclined by 15-25 degrees palmar, distal articular cup has a cylindrical internal working surface with a radius R2 constituting 2.5-5.5 mm, whose center is offset relative to the axis of symmetry n ozhki down to 0.5-2.5 mm, cup in cross section formed in the shape of a square, the die has a width B2, component 6,5-12,5 mm, and the height H2 component of 4.5-9.0 mm, a cup with a projection height h2, component 0.8-1.5 mm and the width b2 constituting 1.0-2.0 mm, which extends transversely to the cylindrical working surface in a circle, the distal articular cup has oval tapered leg, which horizontal section is formed with a cone angle of 8-12 degrees, and vertically - 4-8 degrees and is inclined 6-10 degrees palmar.Задачей предлагаемого межфалангового эндопротеза является устранение воспаления за счет возможного отрыва коллатеральных
