Objective: to assess the accuracy of the femoral neck resection using the developed "Device for positioning tools for the installation of the femoral component of the hip prosthesis". Material and Methods. On the basis of the Department of traumatology and orthopedics of Voronezh state medical University n.a. N.N. Burdenko conducted experimental studies on 40 models of plastic bones. In the comparison group resection was performed using the proposed device, in the control group — using a standard guide. Results. Experimental studies have demonstrated higher accuracy of femoral neck osteotomy in the comparison group. The average value of the neck filing angle in the frontal plane in the comparison group was 3.2° higher than in the control group (p<0.05), and in the sagittal difference was 3.1°. The average distance from the line of the osteotomy to the apex of the greater trochanter in both groups was not significantly different (p=0.62). Conclusion. The use of the developed device allows to perform osteotomy of the femoral neck with high accuracy, as well as to control the position of the leg endoprosthesis, which helps to reduce the number of complications and improve the quality of life of patients.
