摘要：
1. Endoprosthesis radial head comprising a head whose external surface is adequate to the anatomical shape of the radial head, introduced therein leg formed as a conical chetyrehlopastnym rod, wherein the stem additionally equipped with a ball bearing formed by a distal edge of equidistant transverse grooves, formed along the surface of the head is formed as a sleeve with internal thread and a spherical bottom surface, a concave radially ball bearings, and holds the outer sleeve ezbovoy surface forming the screw pair with the threaded inner surface of the head, provided that the diameter of the ball bearing greater than the internal diameter of the sleeve, and between the bottom edge of the sphericity and the inner threaded surface of the head is formed by a gap equal to 1.0-1.3 mm.2. Endoprosthesis radial head comprising a head, the outer surface of which is adequate to the anatomical shape of the radial head, introduced therein leg formed as a conical chetyrehlopastnym rod, wherein the stem additionally equipped with a ball bearing formed by a distal edge equidistant transverse grooves formed along surface of the head is formed as a sleeve with a spherical head, a concave radially ball bearing, a radial groove formed on the inner surface of the liner And with the annular spring submerged in a radial groove between the bottom edge of the sphericity and the inner threaded surface of the head is formed by a gap equal to 1.0-1.3 mm, provided that the ball bearing diameter larger than the inner diameter of the spring wire diameter1. Эндопротез головки лучевой кости, включающий головку, внешняя поверхность которой адекватна анатомической форме головки лучевой кости, введенную в нее ножку, выполненную в виде конусного четырехлопастного стержня, отличающийся тем, что ножка добавочно оснащена шариковой опорой, образованной с дистального края равноудаленными поперечными пазами, выполненными вдоль поверхности, головка выполнена в виде гильзы с внутренней резьбовой поверхност
