Restoration of thoracic kyphosis by simultaneous translation on two rods for adolescent idiopathic scoliosis

Abstract

Introduction: Sagittal and axial corrections of the three-dimensional deformity characteristic of scoliosis remain challenging.

Materials and method: The author developed a new technique for scoliosis correction consisting of the translation of vertebrae simultaneously towards two rods, which are pre-bent to the correct sagittal profile. Using two rods ensures both reduction and stabilization of the curve. The system includes stable anchorages with polyaxial-threaded extensions that connect to the rods. Deformity reduction is done by tightening nuts simultaneously and progressively on the two rods. Results demonstrate the efficiency of this technique to achieve normal thoracic kyphosis (>20°) in all 99 patients, with a mean gain of 19° of thoracic kyphosis in hypokyphotic cases. Coronal correction was 70-80% with a vertebral rotation gain of 40% where derotation connectors were used.

Conclusions: In a large consecutive series of patients, this new technique allows to achieve a good 3D correction of the scoliosis.
