Growth Modulation of the Scoliotic Spine: Where Are We Now?

Recent developments suggest that it may be not only practical but also feasible to modulate growth of the spine and effectively reverse scoliosis in appropriately selected children. Based on the concept of the Hueter–Volkmann principle, anterolateral vertebral body tethering has now been explored both in animal models and in clinical practice. Early clinical experience has demonstrated powerful proof-of-concept for this exciting new approach, which may in fact overturn our traditional concepts regarding treatment of the skeletally immature child with scoliosis. At the same time, much work is needed to further refine the technology, indications, and limitations, as well as long-term outcomes, of tethering treatment options.
