straight back syndrome

straight back syn·drome

loss of the normal concavity of the thoracolumbar spine with a narrowed anteroposterior chest dimension, resulting compression of the heart between spine and sternum, and consequent prominent precordial pulsations, an ejection murmur, and radiologic evidence of a widened cardiac silhouette (pancaked heart).

straight back syndrome

Straight back and flat chest syndrome A variant position due to ↓ of normal thoracic kyphosis, which ↓ AP chest diameter, ↑ prominence of pulmonary artery and right hilum, displacing heart to left, simulating cardiomegaly Associations ASD, scoliosis; it may cause mild pulmonary vein obstruction and dilation, evoking a harsh late systolic ejection murmur; it is asymptomatic but may be misinterpreted by the examiner, causing an otherwise healthy person to become a cardiac 'cripple'

straight back syndrome

An abnormally erect position of the spine, associated with pectus excavatum, functional cardiac murmurs, and failed back surgery.

Patient discussion about straight back syndrome

Q. My son is complaining about back pain. I also see that his back isn't straight. What can we do? My son is a adorable 8 years old. He is complaining about back pain, that bothers him after he walks a little. I also saw that his back isn't straight and looks like a S. is this deformity connected to his back pain?

A. The normal shape of the spine is very similar to the "S" shape as you can see here

But even if his back isn't deformated, he has back pain and you need to take care of that by going to your pediatrician.
