Comparing minimally invasive surgery to standard surgery for adolescent idiopathic scoliosis

Official title: Minimally Invasive Surgery vs Standard Posterior Approach in the Treatment of Developmental Idiopathic Scoliosis: Randomized Trial.

Run by Istituto Ortopedico Rizzoli · NCT05860673 · Data updated 2026-11-12

This study is testing whether a new, less invasive surgery for scoliosis can work just as well as the traditional surgery for teens and young adults.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adolescents aged 12 to 25 with adolescent idiopathic scoliosis and a scoliotic curve between 40° and 70°.

Probably not a fit

Patients who have previously undergone surgery for scoliosis or have conditions outside of adolescent idiopathic scoliosis may not benefit from this study.

What this trial studies

This randomized trial evaluates the clinical and radiographic outcomes of adolescents with idiopathic scoliosis treated using a minimally invasive surgery (MIS) technique compared to the traditional posterior spinal fusion (PSF) technique. Patients aged 12 to 25 with specific curve measurements will be randomly assigned to one of the two surgical approaches. The study aims to determine if MIS is non-inferior to PSF in terms of curve correction while potentially offering benefits such as reduced postoperative pain and lower transfusion risks. Follow-up evaluations will occur at multiple intervals post-surgery to assess outcomes.

Why it matters

Potential benefit: If successful, this study could provide a less invasive surgical option for treating adolescent idiopathic scoliosis with comparable outcomes to traditional methods.

How similar studies have gone: Other studies have shown promising results with minimally invasive techniques in spinal surgery, suggesting potential for success in this approach.
