Purpose <p>This study describes a novel technique for the treatment of adolescent idiopathic scoliosis (AIS) in skeletally immature patients using pedicle screws to guide vertebral growth. Implants are removed as the skeleton achieved maturity avoiding permanent implants. The radiological outcomes 4 years after removal of then implants are presented.</p> Methods <p>Prospective study of a series of 34 with surgically treated AIS with Risser sign 3 or less. Coronal and sagittal Cobb angles were evaluated at several stages: preoperatively, immediately postoperatively after correction, immediately before and after implant removal, and at 2-year and 4-year follow-up after instrument removal. The results were analyzed comparing Risser 0-1patients and those Risser 2–3.</p> Results <p>The patients’ age at surgery was 13.5 ± 1.4 years (95%CI: 12.9–14.0). There were 15 patients with Risser 0–1 and 19 with Risser 2–3. The mean preoperative Cobb angle was 55.9º ± 5.8º (95%CI: 53.7º-58.2º). After surgery there was a 97.8% of curve correction. Implants were removed 2 years after surgery (mean: 29.4 ± 0.5.4 months; range 21–38). Immediately after removal, minimal loss of correction was noted (mean: 1.4 ± 3.3º). The final amount of correction, 4 years after implant extraction, was 92.4%. Patients with Risser 0–1 showed a higher correction rate than those with Risser 2–3 (102.7% versus 88.5%) 4 years after implant removal. The kyphosis remained unchanged at two and four years after implant removal.</p> Conclusions <p>This novel surgical concept represents a significant advance in the treatment of scoliosis, offering an almost complete correction of the deformity which was stable after removal of implants when patients reach bone maturity. Restoring the shape of the vertebral body at maturity seems to prevent loss of correction after implant removal.</p>
