Abstract

Assessment of early rib hump deformity correction in adolescent idiopathic scoliosis treated with a dynamic derotation brace using the double rib contour sign ORAL PRESENTATION Open Access Assessment of early rib hump deformity correction in adolescent idiopathic scoliosis treated with a dynamic derotation brace using the double rib contour sign Theodoros Grivas*, Georgios Triantafyllopoulos, Christina Mazioti From 10th International Conference on Conservative Management of Spinal Deformities - SOSORT 2013 Annual Meeting Chicago, IL, USA. 8-11 May 2013 Background Scoliotic children and their parents are very much con- cerned about trunk deformity (TD). One of the TD components is the rib hump (RH), which is mainly the expression of rib deformity. Bracing treatment aims not only to hold or correct the central axis (i.e. the spine), but also the TD in the thorax (i.e., the RH). Purpose The goal of this study was to assess the initial correction of the RH in patients with AIS who were treated with the Dynamic Derotation Brace (DDB). Methods In total, 20 children with right thoracic (n= 14) and double curves (n=6) (right thoracic left lumbar) were assessed. The SRS/SOSORT inclusion criteria for brace treatment were used. The Cobb angle was measured on postero-anterior and the rib index (RI) was calculated from the double rib contour sign (DRCS) according to Grivas et al. 2002 on lateral standing spinal radiographs. The reference vertebra from which the RI was assessed was documented. Statistical analysis was done using the Statistical Package Social Science (SPSS) using the t-test. Results The mean thoracic Cobb angle was 27.5 degrees. The posterior margin of the reference vertebra was the T8 in four scoliotics, T9 in two, T10 in four, T11 in six, L1 in two and L2 in two, respectively. The mean pre-brace treatment RI was 1,864 and the early post-brace 1,205, respectively, p=0,007. Conclusions and discussion The RI resulting from the DRCS for the first time was used to asses
