Novel animal model provides sciatica insights

Washington, Apr 30 : Duke University bioengineers and surgeons have developed a new animal model for the painful nerve condition, known as sciatica, which could offer insights to help researchers diagnose and treat it.

Sciatica is characterised by numbness or pain from the lower back to the feet, radiating leg pain or difficulty in controlling the leg.

It is often caused by compression, or pinching, of any of the five nerve roots that combine to make up the sciatic nerve. These roots are the parts of the nerve that pass through openings in the spine to the spinal cord.
