METHOD OF SURGICAL CORRECTION OF THE JUVENILE SCOLIOSIS BY THE MOBILE METAL FIXATION SYSTEM OF THE GROWING SPINE Russian patent published in 2018 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to spinal surgery, and may be applicable for the surgical correction of juvenile scoliosis with a mobile metal fixation system of a growing spine. Install into the apical vertebra and two adjacent periapical vertebrae along the convex surface of the transpedicular screw arc for placement of metal fixation rods with a diameter of 5.5 mm on them. Through one vertebra from the lower periapical vertebra along the convex surface of the arc, two pedicle screws are installed for placement of metal fixation rods with a diameter of 6.0 mm on them. Through one vertebra from the upper periapical vertebra along the convex surface of the arc, screws are installed on two vertebrae for placement of a metal fixation rod with a diameter of 6.0 mm on them. Metal fixation rod with a diameter of 5.5 mm is placed on the two terminal screws at the top and bottom of the instrumentalization zone, and compression is performed on the convex side of the arc in the apical zone, using a metal fixation rod with a diameter of 5.5 mm, the length of which exceeds the length of the instrumentalization zone of the scoliotic arch of the affected spine of the patient by 8–10 cm for possible natural sliding caudally and cranially of the spine synchronously with the patient's height along the partially fixed rod 5.5 mm in diameter. Final fixation of the rod with a diameter of 5.5 mm is performed on the 3 pedicle screws of the apical and periapical vertebrae under the rod of 5.5 mm by finally tightening the screw-nuts on them. Tighten the screw-nuts on the screws under the rod 6.0 mm overlying and underlying vertebrae.

EFFECT: method eliminates surgical staged distractions as the patient grows.
