CORRECTION AND STABILIZATION OF THE SPINE WITH NEW GENERATION IMPLANTS FOR VERTEBRAL CONGENITAL MALFORMATIONS IN CHILDREN AGED ONE TO FIVE YEARS

Abstract

Objectives. To analyze the results of correction and stabilization of the spine with new generation implants for congenital malformation of the vertebrae in children of 1 to 5 years old. Material and Methods. A metal construction for surgical treatment of congenital anomalies of the spine in children of 1 to 5 years old was developed, consisting of transpedicular and laminar support elements. This construction was used in 38 patients with congenital thoracic and lumbar spine deformities associated with malformations of the vertebral bodies. Six patients had an isolated lateral or posterior-lateral hemivertebra in the thoracic spine and 11 – in the thoracolumbar junction, 3 patients had wedge-shaped vertebra in the thoracolumbar spine, and 18 – multiple or combined developmental anomalies of the spine. Initial angulation of scoliotic deformity was 24° to 50° and kyphotic deformity – 20° to 46°. Surgical treatment consisted of one-moment three-staged operation according to developed technique. Results. Correction of deformity within 92–100 % was achieved in patients with isolated hemivertebra in the thoracic and lumbar spine, and posterior wedge-shaped vertebrae in the thoracolumbar junction. In patients with multiple and combined developmental anomalies of the spine the correction of scoliotic deformity was 52–76 % and of kyphotic one – 58–80 %. Conclusion. The suggested metal construction provides the possibility to perform surgery at early stages even for developmental anomalies of the spine posterior support column in patients of 1 to 5 years old with congenital spine deformities.
