Forty-six subsequent procedures were performed in 38 AVBT patients (16%), including 17 conversions to PSF and 16 revisions for excessive correction, compared with 4 revision procedures in 3 PSF patients (1.3% p 50° that may require revision or conversion to PSF. The AVBT group was younger (p 50° was present in 7 AVBT patients (3%), 3 of whom underwent subsequent PSF, and in 0 PSF patients (0%). In the AVBT group, the mean age was 12.1 ± 1.6 years, the mean follow-up was 2.2 ± 0.5 years, 84% of patients were female, and 79% of patients had a Risser sign of 0 or 1, compared with 13.4 ± 1.4 years, 2.3 ± 0.5 years, 84% female, and 43% Risser 0 or 1 in the PSF group. Radiographic, clinical, and Scoliosis Research Society 22-Item Questionnaire (SRS-22) data were compared preoperatively and at the ≥2-year follow-up.Ī total of 237 AVBT patients were matched with 237 PSF patients.

Patients with thoracic idiopathic scoliosis who underwent AVBT with a minimum 2-year follow-up retrospectively underwent 2 methods of propensity-guided matching to PSF patients from an idiopathic scoliosis registry. The present study utilized a large, multicenter database and propensity matching to compare outcomes of AVBT to PSF in patients with idiopathic scoliosis. duPont Hospital for Children, Wilmington, Delaware.Īnterior vertebral body tethering (AVBT) is an alternative to posterior spinal fusion (PSF) for the surgical treatment of scoliosis. 11 Department of Orthopedic Surgery, Nemours/Alfred I.10 Division of Pediatric Orthopedics, Pediatric Specialists of Virginia, Virginia.9 Department of Orthopedics and Sports Medicine, Seattle Children's Hospital, Seattle, Washington.8 Department of Orthopaedic Surgery, University of Missouri Health Care, Columbia, Missouri.7 Department of Orthopedic Surgery, Nemours Children's Health, Jacksonville, Florida.6 Department of Orthopedic Surgery, Mount Sinai Hospital, New York, NY.5 Department of Orthopaedics and Traumatology, Acibadem University School of Medicine, Istanbul, Turkey.4 Department of Orthopaedics, British Columbia Children's Hospital, Vancouver, British Columbia, Canada.3 Department of Surgery, University of Montreal, Montréal, Québec, Canada.2 Department of Orthopaedics, CHU Sainte-Justine, Montreal, Québec, Canada.1 Division of Orthopedics & Scoliosis, Rady Children's Hospital, San Diego, California.
