摘要

FIELD: medicine.;SUBSTANCE: method of the express-modelling wear of a polyethylene insert of a metal cup or a polyethylene cup under dynamic conditions at different angles of horizontal inclination in an experimental module of the hip joint endoprosthesis consists in carrying out long-term and multiple cyclic movements in the hip joint endoprosthesis module under experiment conditions. The experimental module of the hip joint endoprosthesis, which has a leg, a polyethylene insert of the metal cup or the polyethylene cup and a head, consisting of ceramics, metal, metal alloys and other materials with a rough surface, is used in the method. The experimental module of the hip joint endoprosthesis is fixed in the device in such a way that the head is located in the polyethylene cup or in the polyethylene insert of the metal cup of the endoprosthesis module, after which the device with the polyethylene insert of the metal cup or the polyethylene cup is installed in such a way that the longitudinal axis of the module head and neck has a 10-degree deviation relative to the plane of entrance into the polyethylene insert of the metal cup or into the polyethylene cup. After that dynamic tests for joined compression and cyclic twisting in the friction pair are carried out. Then, the worn polyethylene cup or the polyethylene insert and the head with the rough surface are replaced with new ones. The device with the new polyethylene insert of the metal cup or the polyethylene cup is installed in such a way that the longitudinal axis of the module head and neck has a 20-degree deviation relative to the plane of entrance into the polyethylene insert of the metal cup or into the polyethylene cup, after which dynamic tests for joined compression and cyclic twisting in the friction pair are carried out, after which the worn polyethylene cup or the polyethylene insert and the head with the rough surface are replaced with new ones. Then the device with the new polyethylene insert of the metal cup or the polyethylene cup is installed in such a way that the longitudinal axis of the module head and neck has a 30-degree deviation relative to the plane of entrance into the polyethylene insert of the metal cup or into the polyethylene cup, after which dynamic tests for joined compression and cyclic twisting in the friction pair are carried out, after which the wear of the polyethylene insert of the cup or the polyethylene cup of the experimental module of the hip joint endoprosthesis is analysed.;EFFECT: efficiency under dynamic conditions.;16 dwg
