FIELD: medicine.
SUBSTANCE: femoral canal is prepared until it has its primary stability and rotational mobility. A rasp file length equal to a prosthesis length is measured. A rasp file seating depth is determined by measuring a distance from an apex of a greater trochanter to a proximal segment of the rasp file. The margin distance is determined by summing up the rasp file length equal to the prosthesis length, and the seating depth, adding from 1 to 3 cm, and the femoral canal is covered with a pin bunch. An allograft is impacted throughout the length of the femoral canal in accordance with the distance specified above. The femoral canal is re-prepared taking into consideration the pre-set seating depth. The femoral component is implanted at the pre-set seating depth. The pin bunch is removed from a diaphysis of femur.
EFFECT: method enables eliminating the risk of femoral component instability.
