Summary

Brace treatment for adolescent idiopathic scoliosis does not negatively impact bone density at the hip and spine. This study found no adverse effects on bone mass in patients undergoing bracing compared to observation.

Area of Science:

  • Orthopedics and Sports Medicine
  • Pediatric Endocrinology
  • Radiology

Background:

  • Limited data exists on the impact of bracing on bone mass in adolescents with idiopathic scoliosis.
  • Concerns raised about potential permanent bone mass loss and increased osteoporosis risk from long-term brace use.

Purpose of the Study:

  • To investigate if bracing during growth influences bone density in adolescent idiopathic scoliosis.
  • To determine if any observed effects are local to the spine or systemic.

Main Methods:

  • Case-control, cross-sectional analysis of 85 adolescent females with scoliosis (20-45 degrees).
  • Bone mineral density measured at hip and spine using dual-energy x-ray absorptiometry.
  • Evaluated dietary calcium, activity level, body mass index, pubertal status, and Cobb angle.

Main Results:

  • No significant difference in L3 vertebral body and femoral bone mineral density between braced and observed groups after adjustments.
  • Pubertal status influenced spinal bone mineral density but not femoral bone mineral density.
  • Brace use did not affect bone mineral density; pubertal status and BMI explained 53% of spinal bone mineral density variation.

Conclusions:

  • Brace treatment for adolescent idiopathic scoliosis does not adversely affect bone mass at the spine and hip.
  • Findings suggest bracing is safe concerning bone density in this population.
