FIELD: medicine.
SUBSTANCE: method for instant simulation of abrasive wear of a polyethylene insert of a metal cup or a polyethylene cup of an experiment module of a hip implant, which has a head with a leg, a polyethylene insert of a metal cup or a polyethylene cup and a cup clamping device. The head consists of ceramics or metal alloys and has a rough surface. The experiment module of the hip implant is clamped in a special device so that the device is placed into the polyethylene insert of the metal cup or into the polyethylene cup of the module of the implant; a long axis of the head and leg of the module of the implant are perpendicular to a plane of an input into the polyethylene cup or polyethylene insert of the metal cup of the module of the implant. That is followed by dynamic co-compression and cyclic torsion tests in a friction pair; the experiment is terminated by producing the abrasive wear of the polyethylene insert of the metal cup or the polyethylene cup.
EFFECT: invention makes it possible to study the abrasive wear of the polyethylene insert of the cup or the polyethylene cup of the experiment module of the hip implant with the long axis of the head and the axis of the leg of the experiment module arranged perpendicularly to the plane of the input into the polyethylene cup or polyethylene insert of the metal cup of the module of the implant.
