Despite the large number of proposed methods of osteosynthesis of the femoral neck, a significant number of fracture nonunions and migrations of screws remains. A comparative study of bone density in different segments of the femoral head was made. There were used histological and radiological methods. It was revealed that in the upper segments of the femoral head there was a higher density than in the lower ones. It is concluded that in the femoral neck osteosynthesis by three screws their location should be at the vertices of the triangle facing ground up.

Keywords: femoral neck fractures, osteosynthesis with three screws, bone density of the femoral head
