Can Botox-Like shots straighten Teens' spines?
NCT ID NCT03935295
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether injecting Dysport (a muscle relaxant similar to Botox) into back muscles, combined with wearing a brace, can improve spine curvature in teens aged 10-16 with mild to moderate scoliosis. About 90 participants will receive either Dysport or a placebo, plus a custom brace. The main goal is to see if the curve angle changes over time.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- abobotulinumtoxinA (Dysport)
- What this could lead to
- If it works, this could offer a non-surgical way to slow or reduce spine curvature in teens with scoliosis, potentially avoiding the need for surgery.
- What could go wrong
- This is a small Phase 4 study with only 90 participants. The treatment may not improve curve progression more than bracing alone, and injections carry risks like muscle weakness or pain.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion criteria: * Clinically determined idiopathic nature of scoliosis * Age 10-16 years * Risser stage 0,1,or 2 * major curve of 20°-40° * curve apex caudal to T7 vertebra * ability to adhere to bracing protocol * Botulinum toxin naïve or previously treated greater than 6 months prior to study entry Exclusion criteria: * Diagnosis of congenital scoliosis, neuromuscular scoliosis, or other "reason" for scoliosis - Previous surgery at any segment of the spine * Current need for surgery at any level of the spine * Treatment with any drug known to interfere with neuromuscular function * Any other medical condition, laboratory or diagnostic procedure finding that might preclude administration of BTX * Ongoing infection at the injection sites * Diagnosis as either resistant or sensitive to botulinum toxin treatment of any type or to any components of the BTX formulation * Cow milk protein allergy
