Abstract

Purpose: To compare the anthropometric parameters, including weight, height, body mass index and bone mineral density in patients with adolescent idiopathic scoliosis, with those in age- and gender-matched controls.
Materials and Methods
The weight, height, body mass index and bone mineral density of 72 girls, aged 11-14 years, and newly diagnosed with adolescent idiopathic scoliosis were compared with 54 age-matched female control subjects. The bone mineral density of the lumbar spine, non-dominant femoral neck, greater trochanter and Ward's triangle were measured using dual- energy X-ray absorptiometry.
Results
The average age of the 72 adolescent idiopathic scoliosis patients and 54 controls were 12.9 years and 13.1 years, respectively. There was no significant difference in age between the 2 groups. The weight, uncorrected and corrected body mass index, as well as the bone mineral density of the lumbar spine and femoral neck were significantly lower in the adolescent idiopathic scoliosis patients than those of the controls. There were no significant differences in bone mineral density of the greater trochanter and Ward's triangle between the 2 groups.
Conclusion
The weight, body mass index and bone mineral density of the lumbar spine and femoral neck in the adolescent idiopathic scoliosis were significantly lower than the controls. Further studies will be needed to determine the cause and early treatment effects of the low weight, body mass index and bone mineral density in patients with adolescent idiopathic scoliosis.

  Fig. 1 The scoliotic curvature of the spine in patients with adolescent idiopathic scoliosis may present difficulties in measuring the spinal bone mineral density reliably. In order to minimize this problem, the amount of rotation in patients with adolescent idiopathic scoliosis was determined by (A) pre-scanning of the spine and measuring the bone mineral density of the lumbar spine in (B) the neutral position.
