Can you tell me the difference between scoliosis and spondylolisthesis?

Curve vs slip: Spondylolisthesis means one spine bone has shifted forward on the one below it. It is seen on a side view x-ray (or other imaging study). Scoliosis is a curve seen on the frontal view x-ray (a straight line is normal). In reality though, scoliosis is a rotational deformity; the individual bones are rotated from the normal position, affecting the shape in the front view mainly, but also in others.

Yes : Both are spinal deformities. A scoliosis is a rotational deformity of the spine making it look curved while a spondylolisthesis is a shifting of one vertebral bone over another. Sometimes you can feel the step off that this can create when running a hand over the middle of someone's back that has a spondylolisthesis.
