Background: To quantify the morphological changes in the surface of the back of adolescents with idiopathic scoliosis as a result of treatment with braces and to correlate them with radiographic changes. Material and methods: An analytical, cohort, prospective study on a sample of 31 adolescents with idiopathic scoliosis. We divided them into two groups: eleven treated with braces and twenty without them. Quantification of the deformity was performed on two separate occasions with an interval of one year using three systems: 1) angle of trunk rotation (scoliometer); 2) surface topography; 3) full spine X-rays. Results: No statistically significant differences were detected between the initial and final assessment of the topographic and radiographic variables in the group with braces. In the untreated group, only in measures with the scoliometer significant differences were registered. A positive correlation was found between the Cobb angle difference of the main curve with two topographic variables that quantify the asymmetry in the axial and coronal plane, respectively. Discussion: In following patients with scoliosis treated with braces, we should consider and evaluate not only radiographic parameters such as the Cobb angle, but also clinical and topographic parameters that quantify the external deformity of the back, as there is a clinical-radiographic discrepancy amply demonstrated in the literature. The improvement of the external shape of the back is a very important factor for the patient, and can influence a better completion of the orthopedic treatment. In our study, the scoliotic curve and external deformity of the back remained stable during the follow-up period in both treated and untreated patients.
