METHOD OF TREATMENT OF OPERATIONAL OSTEONECROSIS OF THE FEMORAL HEAD Russian patent published in 2016 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: intertrochanteric osteotomy perform rotary, rotation of the head and neck of the femur with breeding focus avascular necrosis from the load and osteosynthesis. At the same time the greater trochanter of the femur is cut off in the sagittal plane with preservation of periosteal blood circulation and fixing rotator tendons. Forming surface intertrochanteric osteotomy in a hinge form 1/3 of a cylindrical surface on which to rotate the neck of the femur head 35°-45°, relative to the axis of the femur and the greater trochanter to the preservation of the natural orientation of the latter relative to the axis of the femur.

EFFECT: method allows to increase the contact area and the density of the surface of the osteotomy, improve blood circulation and conditions of consolidation, as well as to preserve the natural balance of the rotator muscles that attach to the greater trochanter.
