Adolescent idiopathic scoliosis is a three-dimensional deformity with frontal, sagittal, and axial impairment. The purpose of surgical treatment is to correct the deformity, obtaining a stable balanced spine. Mobile segments of the lumbar spine should be preserved when possible with restoration of good clinical alignment on all three planes. To date, frontal plane correction ceased to be the most challenging aspect due to outstanding technological improvements of the available instruments. However, sagittal and axial alignment restoration remains difficult to achieve.

Direct vertebral rotation represents the most effective maneuver for axial deformity correction. Furthermore, indirect vertebral rotation techniques can be helpful to improve axial correction, while allowing good sagittal and frontal contour. A vertebral translation technique combined with the use of two differently shaped rods have demonstrated effectiveness in rib hump deformity reduction and kyphosis restoration together with frontal plane correction. Used correctly, differently shaped rod translation technique acts as a real tridimensional corrective maneuver.

The aim of this video is to schematically describe the concept of differently shaped rods translation and direct vertebral rotation for surgical treatment of adolescent idiopathic scoliosis.
