This animation shows how a back bend test is performed to help diagnose idiopathic scoliosis.Click
the navigation arrows below the animation screen to play, pause, rewind or fast-forward
the animation. This animation contains sound.Scoliosis is a condition in which the spine curves sideways,and
idiopathic scoliosis means that the cause isn't known.The spine is made up of many small
bones called vertebrae.These are separated by discs which allow the spine to bend.This
structure of vertebrae and discs is supported along its length by muscles and ligaments.
Many people have a slight sideways curvature of their spine and in most cases this is considered
normal. Scoliosis is defined as a curve of more than 10 degrees. The curvature is often
shaped like the letter S or C, and the spine may also be twisted. In scoliosis the vertebrae
twist and curve. If you have scoliosis, you may have one shoulder blade higher than the
other or it may be more prominent. Your hip may also be higher on one side. Here we show
one shoulder blade higher than the other, and a hip which is higher on one side. To
check if you have scoliosis, bend over from the waist with legs and arms straight and
the palms of your hands together. If you have scoliosis, your ribs may be more prominent
on one side when they are viewed from the back. You may also have one shoulder blade
higher than the other, or it may be more prominent. If you suspect that you have scoliosis, get
advice from your GP. This is the end of the animation. Click on the animation screen to
