METHOD FOR PROXIMAL FEMUR DEFECT TREATMENT Russian patent published in 2017 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: method includes application of an external fixation device to the femoral 1 and pelvic 2 bones, closed metered lowering of the apex of large trochanter 7 to the lower edge of acetabulum 8 is performed using the external fixation device, soft tissues along the outer surface of the upper third of the thigh are exfoliated by the open method, middle and small gluteus muscles 17 are separated subperiosteally from the top of the large trochanter, arthrotomy and revision of the acetabulum are performed, shape of the large trochanter apex is modeled in accordance with the acetabulum size, the femur is crossed over small trochanter 10, proximal femoral fragment 11 is unfolded in the frontal and horizontal planes, forming a cervico-diaphysial angle and anteversion angle, femoral fragments are fixed with implant 13 at the obtained position, the larger trochanter top is directed to the acetabulum, transverse osteotomy 14 over acetabulum is performed, the acetabulum is transposed, inclined outwards and to the front, pelvic bone fragment is fixed to support 4, gluteus muscles are moved to the distal end of the proximal femur fragment together with the periosteum, stabilizeed and fix theobtained position and unload the hip joint EFD, hip joint passive movements are trained, after consolidation of the osteotoming fragments and achievement of stability in the hip joint, EFD is dismantled, the hip is fixed with a splint.

EFFECT: favorable geometric relationships in the joint.
