METHOD FOR TREATING ISCHEMIC DEFORMATION OF PROXIMAL FEMUR Russian patent published in 2019 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, to methods of surgical treatment of locomotor diseases, namely to methods of treating proximal thigh deformities in children. Method comprises mounting an external fixture apparatus on the femoral and iliac bones, hip integrity disorder, formation of proximal and distal bone fragments by C-shaped femoral osteotomy through the base of the neck from the fossa to the lower edge of the neck, movement and fixation of bone fragments using an external fixation apparatus, characterized by that additionally performing oblique osteotomy of greater trochanter, in the direction from the outside to the inside and from the bottom upwards at an angle in range of 30 to 35° to femoral longitudinal axis, bone rods are inserted separately into bone fragments, establishing bone rods in a lateral portion of a proximal bone fragment comprising a neck with a head and an apex of a bone fragment containing a large spit, one-stage corrective turning of proximal and distal bone fragments of femur is performed in two planes, free ends of bone rods are fixed in equipment, performing a gradual hardware transposition of a bone fragment containing a large spit, restored to correct disturbed orientation of greater trochanter relative to head of femur, stabilized position of greater trochanter, fixing bone fragments in a corrected position with intraosseous screws, removing the bone rods through the lateral portion of the proximal bone fragment containing the neck with the head, and an apex of the bone fragment containing the greater trochanter, unloading the hip joint by an external fixation apparatus, after consolidation of bone fragments in zones of osteotomy the apparatus is dismantled and development of motions in hip joint is performed.

EFFECT: provision of favorable geometrical interrelations in hip joint, improvement of conditions of gluteus muscle functioning achieved by means of minimum violation of femoral integrity and adequate unloading of an articulation in postoperative period.
