method belongs to the medicine, experimental medicine, biomechanics, u044du043du0434u043eu043fu0440u043eu0442u0435u0437u0438u0440u043eu0432u0430u043du0438u044e hip replacements.the technical result is the development of an efficient and accurate way to determine the area of the inner surface of the polyethylene liner wear u0432u043eu0433u043du0443u0442u043eu0439 me u0442u0430u043bu043bu0438u0447u0435u0441u043au043eu0439 cups or plastic cups in the experimental module of the hip joint implant with the use of computer hardware.the technical result is achieved in the following way: contrast ink station wear of polyethylene, then the whole internal surface of the u043fu043eu043bu0438u044du0442u0438u043bu0435u043du043eu0432u043e marker the metal insert cups or plastic cups is shared by the two mutually u043fu0435u0440u0435u043au0440u0435u0449u0438u0432u0430u044eu0449u0438u043cu0438u0441u044f angle half lines into four equal sectorsfurther, the resulting sectors further divided into separate segments on wear surface not more than 164 mm, then consistently set the implant from carrying the camera microscope "leica M125" so that to obtain the maximally flat images of all the individual segments of the wear and tear.which has the system block and with the help of the program image scope s "bring on the monitor, and then use the function computing the square images determine the value space allocated to individual segments of the wear and tear, and then determine the value of each of the four sectors of wear, then wear values of u0441u0443u043cu043cu0438u0440u0443u044eu0442 each sector and receive the total value area of wear and tear.
