Background:
Boston brace treatment has been used for conservative treat-
ment of Adolescent Idiopathic Scoliosis, since the 1970´ies. The treatment has
been shown to stop the progression of the deformity, in several long time stud-
ies.
Purpose / Aim of Study:
The purpose of this retrospective study was to ex-
amine the curve characteristics in patients, who progressed during brace treat-
ment.
Materials and Methods:
153 AIS patients were treated with Boston braces, at
Rigshospitalet from 1983-1990. A retrospective study was performed, of the
radiological characteristics of the brace treated patients. Curves were classified
according to the King Moe classification, and apex was described. Curve magni-
tude is described by Cobb measurement, The Harrington factor was calculated
and Spinal rotation was described using Pedriolle.
Findings / Results:
138/153 patient completed their brace treatment and
was included in this study. Mean age when brace treatment was initiated was
14.1 y (+/- 1.6 y), Time in brace 2.6 y (+/- 1.0 y) and Mean Cobb before treat-
ment 39° +/- 10°. Brace treatment did not alter the spinal rotation (p> 0.3),
age at start Brace treatment (p>0.8) or Age at menarche (p>0.05) was not
correlated with progression during brace treatment. The curve correction was
significant better in curves, with apex between Th11 and L1 (p< 0.0001). A
correlation was seen in between the in brace correction and Cobb angel during
side bending films pre- treatment (p< 0.002). The Harrington Factor seems to
correlate with progression during brace treatment (p< 0.001) and no patients
with a Harrington Factor less than 5 ° progressed during Brace treatment.
Conclusions:
Boston braces are effective in the conservative treatment of AIS.
Curves should be evaluated prior to brace treatment and close attention is rec-
ommended if risk factors are identified.
