Anterior cervical discectomy and fusion (ACDF) is a surgical procedure to treat nerve root or spinal cord compression by decompressing the spinal cord and nerve roots of the cervical spine in order to stabilize the corresponding vertebrae. This procedure is used when other non-surgical treatments have failed. Anterior cervical discectomy
The nucleus pulposus (the jelly-like center of the disc) of the herniated disc bulges out through the annulus (surrounding wall) and presses on the nerve root next to it. This nerve root becomes inflamed and causes serious pain. The problem can also be caused by degenerative disc disease (spondylosis). The disc consists of about 80 % water. When one grows older, the disc starts to dry out and shrink, causing small tears in the annulus and inflammation of the nerve root.
