Surgical Outcome of Three-Dimensional Correction of Adolescent Idiopathic Scoliosis

Abstract

Background: Adolescent idiopathic scoliosis is an abnormal curvature of the spine that appears in late childhood or adolescence. Instead of growing straight, the spine develops a side-to-side curvature, usually in an elongated S or C shape; the bones of the spine are also slightly twisted or rotated. To prevent further curve progression and obtain a balanced spine, surgery remains the mainstay of treatment for idiopathic scoliosis (IS). Objective: This study aimed to discuss three dimensional surgical techniques used for correction of adolescent idiopathic scoliosis, evaluating their feasibility, efficacy and safety. Patients and methods: This study was conducted in Mansoura University Hospital and Alexandria University Hospitals between September 2018 and April 2021. 3D surgical correction was performed for 91 patients complaining of idiopathic scoliosis, and not responding to conservative measures and not associated with neurological affection. Results: According to Lenke classification, there were 56 patients (61.5%) with type 1 curve type , 9 patients (9.9%) with type 2, 7 patients (7.7%) with type 3, 7 patients (7.7%) with type 5 and 12 patients (13.2%) with type 6. Mean preoperative height was 1.60 m while mean postoperative height was 1.66 m. with significant increase in height postoperatively (p < 0.001). Mean percentage height gain was 3.91%. Conclusion: We do believe that the posterior only approach 3D correction is an effective method in management of AIS concerning correction of Cobb angle, shoulder balance and spinopelvic parameters and recommend it as the best way nowadays to treat this disease.
