Spontaneous Proximal Thoracic Curve Correction After Isolated Fusion of the Main Thoracic Curve in Adolescent Idiopathic Scoliosis

Abstract

Spontaneous proximal thoracic curve correction consistently occurs after instrumented correction of the main thoracic curve. Furthermore, this spontaneous correction is as good as or slightly better after an ASF versus PSF of the MT curve. The preoperative side bender radiographs (PT curve flexibility) positively correlate with the postoperative spontaneous PT curve correction.
