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.Interphalangeal prosthesis brush comprises a distal articular cup and the proximal articular head with legs.The novelty of the claimed interphalangeal prosthesis brush is distal articular cup is a parallelepiped one of whose faces is the first recess having a cross section in the shape of a rectangle with sides l and h, a rectangle becomes semicircular shape with a radius R, this same face is a second recess, a plane of symmetry which coincides with the plane of symmetry of the first recess and passes through the brush interphalangeal prosthesis, the second recess has a section in the shape of a rectangle with sides l1 and h1, rectangle moves in a semicircle with a radius R1, on the other face of the box is formed a third groove having a cross section in the shape of a rectangle whose width l2, side h2, L1 the length of the leg distal articular cup has the shape of a truncated cone with an apex angle of 11-13 degrees and a lower base, which is provided with a diameter D1, the upper edge of the legs has a distal articular cup rounding whose radius r1, on the lateral surface of the distal legs articular cups made circular grooves which have a depth h4, circle-section O groove has a wedge shape with an angle of 18-22 degrees and rounding with radius r2, a location distal to the abutment legs are two articular cup retainer, which have a wedge shape with an angle of 25-35 degrees, a height h5, the width l3, L2 length, except on the side of the distal articular cup, adjacent to the leg made longitudinal and transverse grooves of semicircular cross-section with a radius R2 and a depth h6, the length of each of the longitudinal and transverse groove is limited to the same surface of the two clamps and the foot, crossing etc. partite and transverse grooves form projections uniformly distributed over the surf
