RESULTS OF SURGICAL TREATMENT OF CHILDREN WITH CONGENITAL THORACOLUMBAR KYPHOSCOLIOSIS

Objective. To analyze results of surgical treatment of children with congenital deformity of the thoracolumbar junction of the spine caused by isolated vertebral malformations.

Material and Methods. Surgical treatment results in 37 patients aged 10 months to 12 years with congenital scoliosis caused by isolated lateral and posterolateral hemivertebrae in the thoracolumbar junction were analyzed. Magnitude of scoliosis before surgery was 18 to 52°, and that of kyphosis - 4 to 49°. Extirpation of the abnormal hemivertebra was performed in 33 (89.2 %) patients, and limited resection - in 4 (10.8 %).

Results. Correction of scoliotic deformity after surgical treatment was 85.0% (0-26°), and correction of kyphotic component - 78.6 % (15-23°). Compensatory cranial and caudal counter curves leveled out at the background of the primary curve correction in all patients. Destabilization of instrumentation requiring repeat surgery was observed in two children. The findings showed the efficacy of the surgical treatment by main objective measures in 81.0 % of patients.

Conclusion. Progression of congenital spinal deformity with lateral and posterolateral hemivertebrae in the thoracolumbar junction requires an early radical surgical correction with restoration of the spinal canal anatomy and physiological curves of the spine at the level of deformity.
