Retrospective review.To report the results of vertebral body stapling (VBS) with minimum 2-year follow-up in patients with idiopathic scoliosis.While bracing for idiopathic scoliosis is moderately successful, its efficacy has been called into question, and it carries associated psychosocial ramifications. VBS has been shown to be a safe, feasible alternative to bracing for idiopathic scoliosis.We retrospectively reviewed 28 of 29 patients (96%) with idiopathic scoliosis treated with VBS followed for a minimum of 2 years.Risser sign of 0 or 1 and coronal curve measuring between 20 degrees and 45 degrees .There were 26 thoracic and 15 lumbar curves. Average follow-up was 3.2 years. The procedure was considered a success if curves corrected to within 10 degrees of preoperative measurement or decreased >10 degrees . Thoracic curves measuring <35 degrees had a success rate of 77.7%. Curves which reached < or =20 degrees on first erect radiograph had a success rate of 85.7%. Flexible curves >50% correction on bend film had a success rate of 71.4%. Of the 26 curves, 4 (15%) showed correction >10 degrees. Kyphosis improved in 7 patients with preoperative hypokyphosis ( 10 degrees. Major complications include rupture of a unrecognized congenital diaphragmatic hernia and curve overcorrection in 1 patient. Two minor complications included superior mesenteric artery syndrome and atelectasis due to a mucous plug. There were no instances of staple dislodgement or neurovascular injury.Analysis of patients with idiopathic scoliosis (IS) with high-risk progression treated with vertebral body stapling (VBS) and minimum 2-year follow-up shows a success rate of 87% in all lumbar curves and in 79% of thoracic curves 35 degrees were not successful and require alternative treatments.
