Study Summary

This trial will compare the safety of a new scoliosis treatment (AVBT) to the current standard of care (fusion).

Who is the study for?
This trial is for boys and girls aged 10-16 with moderate to severe scoliosis who still have at least a year of growth left. They must have specific types of scoliosis (Lenke 1, 2, 3C, or 5) with curves between 40-70 degrees. Participants need understanding parents who can consent and commit to follow-up visits. It's not for those pregnant, with certain allergies, substance abuse history, previous scoliosis surgery or other forms of scoliosis.Check my eligibility
What is being tested?
The study is testing the safety of AVBT using Zimmer Biomet Tether System or Dynesys components in young patients with scoliosis against traditional spine fusion methods. Researchers will compare outcomes from both treatments over short-term follow-ups.See study design
What are the potential side effects?
Potential side effects may include pain at the site of surgery, infection risks associated with any surgical procedure, possible allergic reactions to materials used in devices if unknown allergies exist, and complications related to spinal surgeries such as nerve damage.

Dr. Larson is zealous in her attempts to get surgeries done on children. She's been known to make malicious referrals to CPS in order to get her way. In my opinion, she's a monster. If you have no other choice but to use her services, make sure your child is an organ donor opt-out. I would not put anything past her.
