FIELD: medicine.
SUBSTANCE: scoliotic spinal column is approached; a short apical rod and a second long rod positioned along the gibbus are inserted and fixed; a scoliotic curve is de-rotated from a frontal to sagittal plane; a third long rod is inserted and fixed along a convex side for rigid fixation thereof; a dorsal spondylosyndesis is created with bone grafts to be placed between the vertebras and a metal retainer laid along the spinal column. Screws are additionally inserted transpedicularly in Roy-Camille point along all the vertebras of the expected spondylosyndesis, and also along a convex surface of the primary curve from superior to inferior neutral vertebras. Inserting the screws is followed by performing a posterior (Smith-Petersen) osteotomy in apical and para-apical regions; mounting a short apical rod at the level of a scoliotic curve apex and a long rod positioned along the gibbus onto a concave side of the scoliotic curve involves pre-fixing the apical rod and a rod positioned along the gibbus with retainer rings left loose. A rod rotator is then used to de-rotate the scoliotic curve from the frontal to sagittal plane simultaneously by the apical rod and a long rod positioned along the gibbus. That is followed by additional segmental corrective medial vertebral rotation by heads of the implanted transpedicular screws, and the scoliotic spinal column is fixed completely to the apical rod and a rod positioned along the gibbus by tightening the retainer rings on the transpedicular screws. After the third long rod has been rigidly fixed on the convex side of the scoliotic curve, and the dorsal spondylosyndesis has been created by means of the bone grafts, the wound is closed.
EFFECT: method enables providing the more effective elimination of a gross scoliotic spinal deformity in three planes, achieving the reliable and desired parameters of the gross spinal deformity correction with the reliable stabilisation of the spinal column, and preventing the patient's disability and increasing the patient's quality of life.
