SpineCor and rigid braces both have both results testifying to their effectiveness in Adolescent Idiopathic Scoliosis (AIS) treatment: an RCT recently compared the two, showing the superiority of rigid braces. In a previous study, we found similar short- term results in curves between 20° and 30° Cobb.
The objective of this study was to compare the short-term results of the Spinecor vs SPoRT brace for AIS in this selected population.
Study design: retrospective controlled study. Population: Rigid Brace Groups (RBGs) 20 patients (16 female), age 13±1, Cobb 24±5°, ATR 8±3°, TRACE score 7, Risser 0-3. Spinecor Group (SG): 41 patients (33 females) age 13±1, Cobb angle 24±5°, ATR 8±3°, TRACE score 6, Risser 0-3. Both groups were treated with a full-time brace (18 to 23 hours per day upon initial prescription). Clinical and radiological evaluations were performed at the beginning and end of treatment. Main outcome measures: Cobb angle (changes > ±5), ATR, TRACE (changes ≥3). Statistics: Chi square, t-test.
Considering patients with more than 5° of Cobb angle change, 40% improved, 45% remained stable and 15% worsened in the RBG vs. 22%, 34% and 44% (p<0.05), respectively. No differences were found for ATR. For TRACE, there were no differences among groups: in RBG, 50% improved and 50% were stable, vs. 65%, 31% and 5% worsened (p>0.05).
Conclusions and discussion
Both treatments showed to be effective in improving the aesthetics in AIS. For the other parameters, the SPoRT brace seemed to be more effective than the SpineCor to avoid curve progression, since the number of worsened patients was much higher for the SG. The main limits of the study were the retrospective design and the small population, so further studies are required.
