Description

Изобретение относится к медицине, преимущественно к травматологии и ортопедии и может быть использовано при замещении дефектов длинных трубчатых костей.The invention relates to medicine, mainly to traumatology and orthopedics, and can be used to replace defects of long tubular bones.

Известен эндопротез метаэпифиза длинной трубчатой кости, содержащий корпус и эндопротез головки бедренной кости [1] .Known endoprosthesis of a metaepiphysis of a long tubular bone containing a body and an endoprosthesis of the femoral head [1].

Недостатком известного эндопротеза является то, что он не обеспечивает восстановления двигательных функций конечности и возможно отторжение на почве биологической несовместимости тканей.A disadvantage of the known endoprosthesis is that it does not provide restoration of the motor functions of the limb and may be rejected due to biological tissue incompatibility.

Целью изобретения является улучшение восстановления двигательных функций конечности.The aim of the invention is to improve the recovery of motor functions of the limb.

Поставленная цель достигается 20 тем, что в эндопротезе, содержащем корпус и эндопротез головки бедренной кости, поверхность корпуса имеет борозды, углубления и сквозные каналы, на одном из концов корпуса ук- 25 реплен стыковой узел, состоящий из стержня с рядом концентричных цилиндрических участков с уменьшающимися диаметрами, на поверхности которых выполнены продольные и поперечныеThis goal is achieved 20 by the fact that in the endoprosthesis containing the body and the prosthesis of the femoral head, the surface of the body has grooves, recesses and through channels, at one end of the body the butt joint is made, consisting of a rod with a number of concentric cylindrical sections with decreasing diameters on the surface of which longitudinal and transverse

Преимуществами предлагаемого эндопротеза являются исключение вероятности отторжения на почве биологической несовместимости, сохранение функциональной прочности, возможности вос15 становления движений конечности за счет прикрепления мышечных окончаний к корпусу эндопротеза и высокая биохимическая пассивность конструкционного материала, исключающая раздражение 20 костных и мягких тканей.The advantages of the proposed endoprosthesis are the elimination of the possibility of rejection due to biological incompatibility, the preservation of functional strength, the possibility of restoring limb movements due to the attachment of muscle endings to the endoprosthesis body and the high biochemical passivity of the structural material, which excludes irritation of 20 bone and soft tissues.
