Is there any risk of paralysis involved in the donation procedure that happens under general anaesthesia?

Stem cells are not collected from the spinal cord or spinal column, which means there is no risk of paralysis.

The spinal cord and bone marrow are sometimes confused, but they are separate. Your spinal cord is a bundle of nerves running down the length of your spine, protected by the spinal column. Bone marrow, on the other hand, is formed inside bones. Stem cells are collected from the bone marrow of the hip bone.
