Long-Term Follow-Up of Ais Treated Surgically With Pedicular Screws

Abstract

Objective: In the last three decades, there have been great advances in the surgical treatment of adolescent idiopathic scoliosis. There are few studies that focus on the long-term clinical and radiographic results of AIS operated on with pedicle screws that also consider psychological repercussions. Methods: We conducted an observational longitudinal study. We reviewed the AIS cases that were operated on with pedicle screws in our center between January 2009 and December 2010. We conducted follow-up until July 2019. A short questionnaire was administered to assess patient satisfaction and the long-term impact from both psychological and functional points of view. Results: A total of 19 patients met the inclusion criteria. The mean preoperative Cobb was 58°, the postoperative was 23° and at the end of follow-up it was 26°. No major complications were reported. Ninety percent were very satisfied with the overall results of the surgery. Ninety-five percent had no limitation for sports or daily activities and 90% were satisfied with the cosmetic results. Conclusion: The short- and long-term radiographic evolution in patients treated with third generation material presented good clinical results. In 3 cases (16%) loss of correction greater than 10% was reported. The overall satisfaction index and cosmetic results were very good at the end of follow-up despite the low correction rate (60%). There were no major complications and the incidence of functional limitation and pain at the end of the follow-up was very low. Level of evidence IV; Review article.
