ABSTRACT
PURPOSE: Treating idiopathic Early Onset Scoliosis (idiopathic EOS) is challenging due to ongoing growth and extensive follow-ups. While bracing is effective for Adolescent Idiopathic Scoliosis (AIS), its value for children under 10 remains debated. This systematic review and meta-analysis evaluates the effectiveness of spinal bracing in idiopathic EOS, followed to skeletal maturity.
METHODS: We searched Ovid Medline and Web of Science until November 1st, 2023. Studies included idiopathic EOS patients between the ages of 3 and 10 (corresponding to Juvenile Idiopathic Scoliosis), followed to skeletal maturity, with no more than 25% initiating bracing after age 11. The primary outcome was the percentage undergoing scoliosis surgery. Pooled outcomes were calculated using a random effects model and 95% confidence intervals.
RESULTS: Out of 417 studies, 15 met the inclusion criteria, encompassing 868 patients. All were observational with a high risk of bias. The pooled percentage of patients undergoing surgery was 40% (95% CI 27-55%). The percentage of patients with a 5-degree progression or more and those progressing beyond 45 degrees were 44% (95% CI 24-66%) and 33% (95% CI 17-54%), respectively. Factors including larger initial Cobb angles, younger age, smaller in-brace correction, and poor compliance were identified as progression risk factors.
CONCLUSIONS: Bracing may prevent progression to surgery in idiopathic EOS when initiated early, but progression and surgery are still more common compared to adolescents. This is the first systematic review and meta-analysis looking at the success of bracing in idiopathic EOS, followed up to skeletal maturity. The high bias and variability of included studies limit the strength of these conclusions, highlighting the need for high-quality research with innovative trial designs.
LEVEL OF EVIDENCE: IV (systematic review of level IV studies).
