Swayback is a disorder defined by an excessive inward curve of the spine. It differs
from the spine's normal curves at the cervical, thoracic, and lumbar regions, which are,
to a degree, either kyphotic or lordotic. The spine's natural curves position the head
over the pelvis and work as shock absorbers to distribute mechanical stress during
What causes Swayback?
The cause of Swayback is unknown. However, Swayback may be associated with poor
posture, a congenital (present at birth) problem with the vertebrae, neuromuscular
problems, back surgery, or a hip problem.
What are the symptoms of Swayback?
Each child may experience symptoms differently. The major clinical feature of Swayback
is a prominence of the buttocks. Symptoms will vary depending if Swayback occurs with
other defects, such as muscular dystrophy, developmental dysplasia of the hip, or
Back pain, pain down the legs, and changes in bowel and bladder habits are not commonly
associated with Swayback. A child experiencing these types of symptoms requires further
medical evaluation by a physician.
The symptoms of Swayback may resemble other spinal conditions or deformities, or may be
a result of an injury or infection. Always consult your child's physician for a diagnosis.
