What’s the difference between VBT and ASC?
…and how is Anterior Scoliosis Correction (ASC) better than VBT? (ASC vs VBT)
Scoliosis inherently is a process by which the spine is already tethered. In our opinion, the terms ‘tether’ and ‘tethering’ used to describe the technique we perform are not medically accurate.
In most cases, spinal curvatures like scoliosis, and particularly with hypokyphosis, need to be “de-tethered” for optimal correction.
Therefore, we prefer Anterior Scoliosis Correction (ASC) and not VBT (Vertebral Body Tethering). For this and many of the reasons listed on this page, Drs. Antonacci, Dr. Betz, and Dr. Cuddihy, who are pioneers in this field, prefer ASC.
Furthermore, it is the opinion of Drs. ABC that ASC yields aesthetically appealing cosmetic incisions hidden under the arms better than VBT.

What is the difference?
The distinction between Anterior Scoliosis Correction (ASC) and Vertebral Body Tethering (VBT) is an important one best represented by who can be treated. See: ASC Questions and Answers
