Anterior Scoliosis Corrective Surgery (Also Known As “VBT”)

An exciting new approach to scoliosis is Anterior Scoliosis Corrective Surgery, otherwise known as VBT. This approach, begun nearly ten years ago, results in correction of progressive scoliosis and takes advantage of future growth to result in further correction of the scoliosis over time. This occurs through growth modulation in which the tethered side of the spine grows less than the non-tethered side. The advantage of this surgery is that it preserves growth, flexibility, and may result in continuous correction of the spine over time while not stiffening the spine.  The Anterior Scoliosis Corrective Surgery is done through an anterior fusion approach and can be used to correct thoracic and thoracolumbar scoliosis.

Who is a candidate for this surgery?

The most common candidate for this procedure is a growing adolescent (age 10 and older) in whom further growth can be taken advantage of to get more correction of curvature over time. Curvature between 30-70 degrees potentially can be treated with this technique. Indications have expanded to younger children as well as to those who have reached skeletal maturity (end of growth) and who would prefer to avoid a traditional fusion. Dr. Lonner and his team can discuss your particular case or that of your daughter or son to determine whether or not you are a candidate for Anterior Scoliosis Corrective Surgery.

How is Anterior Scoliosis Corrective Surgery performed?

The surgery is performed with a team that includes a general or thoracic surgeon and an assistant spine surgeon in addition to Dr. Lonner. Some patients have a thoracic curve, some a thoracolumbar curve, and some both which will determine whether one or two approaches are required. The incision for each curve is made on the patient’s side and is kept as small as possible. Usually, a scope (VATS) is used to improve visualization and access to the spine through a small incision called a portal. Sometimes two portals are made in addition to the main incision. Through these incisions, titanium screws [which are coated with hydroxyapatite which is the substance that bone is composed of and helps bone to grow into the screws from the vertebrae] are placed across the vertebrae at each level in which the spine is curved (see figure). After the screws are placed and confirmed both by direct visualization and x-ray, a flexible cord rod which is like a rope is attached to the screws and fixed by a set screw at each level after first tensioning the cord rod so as to get a correction of the curvature. After the tensioning has been completed, a final x-ray is done, a chest tube is placed to drain fluid and air, and closure of the incision is performed. An epidural catheter is placed for postoperative (after surgery) pain control. The chest tubes usually are removed within the first 2-3 days. The patient gets out of bed the day after surgery and is able to go home after 3-5 days. After 6 weeks, our patients are allowed to return to sports. The few weeks after surgery before return to full activity allows for bone to grow into the screws and to stabilize them.

Who should perform this procedure?

Candidates for Anterior Scoliosis Corrective Surgery should be cared for by a surgeon who has a great deal of experience in anterior fusion approaches. Dr. Lonner has been performing anterior approaches for the treatment of scoliosis for the past nearly 20 years. Dr. Lonner and his team welcome a visit with you to discuss your treatment.

Patient Story 1

Lonner11

This 12½-year old girl is an avid basketball player and horseback rider. She underwent vertebral body tethering procedure (VBT), which was performed by Dr. Lonner, with excellent correction of her scoliosis. She was allowed to return to full activities 6 weeks following surgery. The video shows the patient bending 3 weeks after surgery.

Patient Story 2

Lonner12

This 15½-year old young man, was treated with right thoracic and left thoracolumbar VBT with near complete correction of his scoliosis. He enjoys basketball and is doing very well.

Patient Story 3

Emiline is a 14-year-old girl who came to see Dr. Lonner for worsening scoliosis. She was braced at the age of 13 and received chiropractic physical therapy which unfortunately did not prevent her curve from progressing. Emiline is an avid tennis player who is USTA junior ranked. Dr. Lonner performed a VBT procedure also known as tethering or flexible fusion.

Emiline is doing very well since her surgery. Her curvature was 100% corrected. She began footwork drills at 4 weeks and rallying at 5 weeks after surgery.

Patient Story 4

Olivia is an active 14-year-old young lady who participates in volleyball, soccer, basketball and track in school. Dr. Lonner performed a corrective scoliosis surgery, Olivia is doing very well and has returned to full participation in sports. Here are a couple of videos of her playing volleyball at 4 weeks and 9 weeks postop! She is #14. We are so thrilled that she has been able to return to her sports and is right back to her life!

I never thought I would be able to jump and run around as much asides at only 4 weeks following surgery. I am very happy today shortly after that I was fully back to playing volleyball and actually played in a tournament in Washington in February.

Thank you, Dr. Lonner!

Patient Story 5

Shelby is a 16-year old girl from Minnesota. She came with her parents to see Dr. Lonner to learn about her options for correction of her scoliosis. Shelby had a severe and worsening idiopathic scoliosis with some back pain as well. Dr. Lonner performed VBT, anterior scoliosis correction for Shelby. Her 71° thoracolumbar curve is nearly 100% corrected after surgery. At 3-month post-surgery, she is back to her Tae Kwon Do practice. She will start lifeguarding in a few weeks and is getting ready for a 2-week trip hiking in the Himalayas with her church youth group.

VBT Scoliosis Surgery XRAY

A Testimony from Shelby's mother - 5 weeks post surgery:

"Today is 5 weeks post op already! We've had a pretty smooth recovery. She is eating and sleeping well, getting regular walks, regaining some weight now after losing about 10 pounds initially. Shelby walked about a mile and a half the day before we left along the East River walkway. She sang in church a week after getting back and has been attending her choir rehearsals.

We are very happy with our decision to work with you all. This has been a life changing event for Shelby. We look forward to sending you a picture when she gets her black belt in Tae Kwon Do (that will be a year or two, but whenever it, you will be in our thoughts that day!)."

Scoliosis Surgery Before & After

A Testimony from Shelby's mother - 3 months post surgery:

"To update further update you on Shelby's recovery, we are doing physical therapy and our therapist is very pleased with her progress. Her posture is much improved- her hips aligned and shoulders getting better weekly.  She has some mild to moderate intermittent pain where the concave side of the curve was. I think that is fairly normal.  Otherwise she feels great and looks great.

She is back to normal activity which means very busy and active. We could literally never have ended that video. Last night she passed her test for another belt in Tae Kwon Do. She will start lifeguarding in a few weeks and is getting ready for a 2 week trip hiking in the Himalayas with her church youth group in June. While she could possibly do all these things with a large lumbar curve, we know that the curve left untreated would keep progressing and the stress of an active life would mean quicker degeneration down the road. Same with fusion rods, and the added issue of lower mobility would almost certainly mean no lifeguarding, no Tae Kwon Do and no hiking trip. VBT surgery has changed the course of her life.

Thank you for all you have done for us."
