Objectives
The objective of this study was to verify the efficacy of con-
servative bracing treatment of adolescent idiopathic scol-
iosis (AIS) according to the best methodological criteria
defined in the literature.
Background
The SRS criteria give the methodological reference frame
to present results of bracing. SOSORT criteria give the clin-
ical reference frame for an appropriate bracing treatment.
The combination of the two has never been presented in
a study until now.
Methods
In this retrospective study, the population included all AIS
patients meeting the SRS inclusion criteria (age 10 years or
older, Risser test 0-2, Cobb degrees 25-40°, no prior treat-
ment, less than 1 year post menarche) that reached the
end of treatment since our database started in 2003. We
had 44 females and 4 males, average age at the start of
12.8 years ± 1.6 years. According to individual needs, 2
patients were treated with Risser casts followed by Lyon
brace, 40 with Lyon or SPoRT braces (14 for 23 hours per
day, 23 for 21 hours per day, and 7 for 18 hours per day),
and 2 with exercises only. Outcome criteria included the
following: SRS (unchanged; worsened over 6°; over 45°
at the end of treatment; surgically treated; 2 years follow-
up); clinical (ATR, hump, Aesthetic Index, plumbline dis-
tances); radiographic (Cobb degrees); and ISICO (opti-
mum; minimum). ANOVA and chi-test were used for
statistical analysis.
Results
The reported compliance during the 4.2 ± 1.4 treatment
years was 90.9% ± 17.6%. No patients progressed over
45°, no one was fused, and this remained true at the 2
years follow-up for the 50% that reached it. Worst and
average curves progressed in 4%, while 8%, 11% and 6%
progressed in thoracic, thoracolumbar, and lumbar curves
respectively. We found highly statistically significant
reductions of maximal (-7.0°), average (-5.6°), thoracic (-
4.2°), and lumbar (-6.7°) curves. Statistically significant
improvements were also found for Aesthetics and ATR,
but plumbline distances diminished. Clinically, less than
10% of patients worsened for all parameters (exceptions:
lumbar ATR and hump), while improvements were very
common. According to ISICO criteria, 88% of patients
had minimum and 65% optimal results.
Conclusion
Respecting SOSORT criteria, the results of conservative
treatment was much better than what was previously
reported in the literature using the SRS criteria.
