Evaluation of Vertebral derotation in the correction of Adolescent Idiopathic Scoliosis

Abstract

Adolescent Idiopathic Scoliosis (AIS) is a 3D deformity of the spine for which no cause can be established, and occur between the age of 10 and skeletal maturity. It is a diagnosis of exclusion, where other possible causes are eliminated.

In scoliosis, it is important to not only assess the curvature in the coronal and sagittal planes but to also quantify the rotation deformity occurring in the transverse plane. The rotation is maximal at the apical vertebra and it is primarily responsible for the rib hump that represents the main cosmetic problem for adolescent patients. Measurement of vertebral rotation is of key significance in the prognosis and treatment of scoliotic curves.

Effectively realigning vertebrae that have rotated out of position is a process called derotation, which has been the most difficult part of the deformity to correct, and it is more important than only correcting coronal deformity.

This prospective study is conducted to evaluate the efficacy of vertebral derotation using SCRR maneuver in the treatment of patients with Adolescent Idiopathic Scoliosis (AIS) by clinical and radiological follow up for 1 year.

In this study, we conducted prospective analysis on 30 patients with AIS, who underwent one stage posterior only
