| Background |
|
|
|
| |
| In
2006 the Scoliosis Research Society (SRS) published
guidelines for all future studies of Idiopathic
Scoliosis treatments. The strict inclusion and
exclusion criteria allowed study of only the
highest progression risk group of patients. Together
with standardised outcome measures, the SRS guidelines
make possible for the first time ever comparison
of treatment methods. Since only the highest
progression risk patients are studied, outcomes
for all brace treatments are not as favourable
as generally believed. However, the first study
in 2007 published in the Journal of Pediatric
Orthopedics shows a very clear difference in
outcome for three different treatment methods. |

SpineCor -
a flexible dynamic brace developed in 1992
TLSO - (generic
term for Boston type) rigid plastic spinal braces
extensively used around the world for over 30
years.
Providence - a relatively
new night-time-only rigid plastic brace used by a small number
of clinics in the United States.
* Patients included in theses studies range from 20° to 50° and Risser
0-3, or pre-menarche. Therapeutic success is defined according to the SRS definitions
as either improvement (Cobb reduction of 6° or greater) and stabilisation
(Cobb increase of up to 5°). |

The results table above shows a
dramatic difference in treatment outcomes:
- 15% success (by SRS definitions) with the most commonly used TLSO versus 59%
with the SpineCor dynamic corrective brace. This made SpineCor 4 times more effective
than TLSO in stopping progression of the curve.
- SpineCor is 76.5% effective in avoiding surgery, Providence is 40% effective
and TLSO is 21% effective.
- Compared to TLSO group of 56%, only 1% of the SpineCor group progress more
than 45°. |
