Vertebral Body Tethering for Curvature of the Spine

Vertebral Body Tethering (VBT) is a surgical procedure that uses a series of screws and a cord to gradually correct the spine of adolescents with scoliosis. Unlike a spinal fusion procedure, VBT allows the spine to move more freely and naturally and gives the child room to grow without always needing additional surgeries.

VBT received FDA approval to be offered by a limited number of surgeons. The Spine Care team at Children's Mercy has received specific training approved by the FDA and the device manufacturer to offer this service. 


Most often, we recommend this procedure for young people ages 9-15 with a curve measurement between 40 and 65 degrees. Your child will be asleep under anesthesia for the procedure, which can be done either endoscopically (through small openings) or through a larger vertical incision.

What to expect before and after vertebral body tetering surgery

Children's Mercy is an American College of Surgeons Verified Center

Before surgery, we will discuss all the treatment options with you and your child, including the potential benefits and risks. We will do x-rays of the spine and sometimes additional imaging studies, such as a CT scan or MRI. We may need to draw some blood as well.

During surgery, the doctor will attach a series of screws into neighboring vertebral bodies on the side of your child’s curve. Then the cord is attached to the screws. Over time, as your child grows, the tether will help to gradually straighten the angle of the curve.

Recovery from a VBT procedure usually takes about 10 days to two weeks. Your child’s care team will teach them very gentle range of motion and trunk balancing exercises while they are in the hospital that you can continue to do together after they go home.

Afterwards, you’ll continue to follow up with your orthopedic surgeon and team. They are available by phone and through the MyChildrensMercy Patient Portal for questions or concerns.
