摘要：
The utility model relates to medicine, specifically to traumatology and orthopedics, and can be used in the treatment of small joints. The essence of the proposed utility model is that the endoprosthesis of the first metatarsophalangeal joint contains a distal articular cup with a leg and a proximal articular head with a leg. the first metatarsophalangeal joint is that the distal articular cup has the shape of a cylinder with a diameter D1 from 14.0 mm to 20.5 mm and a thickness d1 from 4.5 mm to 7.0 mm and a spherical cavity from 1.7 mm to 3.1 mm in the groove, on the sides of the distal articular cup there are symmetrical lateral sections, and on the underside there is a dorsal mark, a grooved surface is made on the back of the distal articular cup, the leg of the distal articular cup is shifted down relative to its center by 0.5-1.5 mm and made in the form of a truncated cone with an angle at the apex of 6 °, with a diameter of the upper base G1 from 5.4 mm to 7.2 mm and a length L1 from 17.0 mm to 22.0 mm, 19-25 transverse grooves and four longitudinal grooves are made on the leg of the distal articular cup； the proximal articular head is made in the form of a segment of a sphere with a radius R from 7.5 mm to 11.0 mm and a thickness d2 from 5.4 mm to 8.6 mm, has a slope of 10 ° relative to the axis of the leg, on the underside the proximal articular head has cut, on the back side of the proximal articular head a grooved surface is made, the leg of the proximal articular head passes through the center of the back side of the proximal articular head and is made in the form of a truncated cone with an angle at the apex of 6 °, diameter of the upper base G2 from 5.1 mm to 7.2 mm and length L2 from 17.0 mm d about 30.0 mm, 14-30 transverse grooves and four longitudinal grooves are made on the leg of the proximal articular head.Полезная модель относится к области медицины, конкретно к травматологии и ортопедии, и может быть использована при лечении мелких суставов.Су
