To compare outcomes of SpineCor brace treatment 1 in AIS patients who were obese with the outcome in patients of normal weight.

From December 1994, 503 patients were treated using the SpineCor brace. One hundred eighty patients have a definitive outcome. The cohort of patients was divided into two groups according to body habitus. Obese patients were defined as those with a body mass index in the 85^th percentile or greater 2. Assessment of brace effectiveness included 1) number of patients whose curves progressed by ≤5 degrees; 2) number of patients whose curves progressed by ≥6 degrees; 3) number of patients with curves exceeding forty-five degrees at the end of treatment; and 4) number of patients who have been recommended/undergone surgery before skeletal maturity.

The results demonstrate that AIS patients who are obese as well as patients of normal weight, treated by the SpineCor brace, have a positive outcome (62% and 66% of success respectively). This is not the case for overweight AIS patients following orthotic treatment using the three point pressure principle 3.

The results suggested that the use of a dynamic brace to improve scoliotic deformations through a new concept and treatment approach re-establishes spinal function, while preserving body movement and growth without being interfered by body habitus.
