Study Design. Single-surgeon retrospective case series. Objective. To validate and further describe clinical and radiographic outcomes of patients undergoing vertebral body stapling (VBS), with the goal of learning if VBS is a safe and effective alternative to bracing for treating moderate idiopathic scoliosis (IS) in the growing pediatric patient. Summary of Background Data. VBS is a growth-modulation technique to control moderate idiopathic scoliosis (IS) while avoiding fusion. Existing studies state successful curve control rates equivalent to bracing, but the majority of reports have come from a single institution. Methods. All IS patients who underwent VBS by 1 surgeon were included. Indications were brace intolerance and a structural coronal curve of 258 to 408. Proportional nitinol staples were used in all cases. Pre- and postoperative radiographs, pulmonary function testing, and physical exam measurements were serially recorded. Results. VBS was performed on 35 patients (28 females, 7 males) with mean age 10.5 years (range 7.0-14.6 years). Total of 31 patients (33 stapled curves) completed follow-up. Preoperative Risser grade was 0 in 31 patients, 1 in 1 patient, and 2 in 3 patients. Stapled curves were controlled with <108 of progression in 61% of cases. Curves <358 had a control rate of 75%, and patients <10 years had a 62% curve control rate. Eleven patients (31%) required subsequent fusions; two curves (6%) overcorrected. Preoperative supine flexibility>30% was predictive of ultimate curve control. No neurologic complications were encountered; 5 patients (14%) developed small pneumothoraces. Conclusion. This series contains the most patients and longest followup reported for VBS. Successful curve control was achieved less frequently than in previous reports, particularly in patients <10 years.
