Traditional spine surgery for large curvatures utilized large incisions in the chest cage to access the front (anterior aspect) of the spine and remove discs and parts of the vertebra or spinal bones (anterior release) to help in the correction of the deformity which is then approached from the back (posterior approach). This anterior approach fell by the way side because it caused a lot of pain, affected lung function and resulted in a big scar and potential complications. As the posterior techniques improved the role of anterior surgery became less important. Nevertheless, as Dr. Lonner has shown in a recent multicenter study, anterior release in addition to posterior surgery with pedicle screws (current technique) provides improved correction of the scoliosis as well as 3-D correction of the spine. For the properly indicated patient, this provides better corrections of the scoliosis than posterior alone.
