Risk of early complication following anterior vertebral body tethering for idiopathic scoliosis

The purpose of this study was to determine peri-operative morbidity associated with anterior vertebral body tethering (aVBT) for idiopathic scoliosis. Of 175 patients treated with aVBT, 120 patients had 2 year follow up and were included in this study. Prospectively collected clinical and radiographic data was analyzed retrospectively. Pre-operatively, the mean patient age was 12.6 year (8.2–15.7 year), Risser 0–3, with main thoracic scoliosis 51.2° (40–70°). Immediately post-operative, scoliosis improved to 26.9° (6–53°; p
