To analyze long-term results of surgical correction and postoperative quality of life in patients with Lenke type V and VI deformities of the spine. Material and Methods. The treatment results of 61 patients (average age 15 years) with Lenke type V–VI spinal deformities and mean follow-up period of 3.3 years were analyzed. The average length of anterior fusion was 12.7 segments. The average length of the primary curve instrumented with pedicle screws was 4.9 segments. Results . The primary curve was 56.6°, after surgical intervention it was reduced to 15.1° (73.3 % correction). Postoperative progression within 3.3 years was 2.1°. Thoracic countercurve was 40.6°, after surgery it was corrected to 15.0° (63.0 % correction). At the final follow-up examination, the thoracic curve was 17.3° (progression 2.3°). Thoracic kyphosis and lumbar lordosis were within the normal ranges. The frontal imbalance was 22.1 mm before surgery and 12.2 mm at the final follow-up examination. The SRS-24 questionnaire data showed a significant score increase in all seven domains. Conclusion . Transpedicular fixation allows achieving a high degree of Lenke type V–VI spinal deformity correction with a stable result and significant improvement in the quality of life of patients.
