Bone density accumulation is not affected by brace treatment of idiopathic scoliosis in adolescent girls.

Bracing for adolescent scoliosis has been postulated to cause permanent loss of bone mass and to predispose to adult osteoporosis. To determine whether brace use affects the rate of bone accretion with growth, the authors conducted a prospective study of 52 girls with adolescent idiopathic scoliosis. Dual-energy x-ray absorptiometry (DEXA) showed a significant increase in spinal bone mineral density (BMD) over a 1-year period of brace wear.
