Abstract

BACKGROUND
Several reports have suggested low bone mineral density (BMD) in patients with adolescent idiopathic scoliosis (AIS). We determined bone mineral status in patients with AIS to evaluate the effect of brace treatment on BMD.
METHODS
BMD was measured in 46 patients (mean age, 17.8 +/- 4.9 years) with AIS (17 with brace and 29 without brace) by dual-energy X-ray absorptiometry scan and compared the results to an age-matched (mean age, 16.6 +/- 3.9 years) control group (n = 54).
RESULTS
The AIS group had significantly lower bone mass at the lumbar spine (Z-score, -1.500 vs. -0.832) and hip (Z-score, -1.221 vs. -0.754) except at the femoral neck. No difference in BMD was found between patients with AIS who used a brace and those who did not.
CONCLUSIONS
The results confirmed that BMD was low in AIS patients and it was not affected by brace treatment.
