Advanced Care for Children with Scoliosis

Scoliosis is a sideways curvature of the spine that affects many children and teens. Most cases are mild, but scoliosis can progress and lead to disabling spine deformities or problems with lung and heart function. Our specialists have the experience and research background to make that determination early on. We use bracing as an effective treatment for many children, reserving surgery for the more severe and progressive cases.

At Comer Children's, we use the latest techniques and medical procedures for pediatric spinal disorders. For example, when children require bone fusion, our physicians use bone graft substitutes that are less painful and heal faster.

Collaborative Approach

Our team approach to care brings together specialists from many disciplines to identify the most effective treatment options for each child. Surgeons in our orthopaedic and neurosurgery departments frequently combine their talents to address complex spinal problems. This collaboration ensures the most effective, comprehensive and safest treatments for our patients.
