ACDF is a type of neck surgery that involves removing the damaged disc to reduce compression on the spinal cord and/or nerve root, and alleviate corresponding pain, weakness, numbness and tingling in the upper limb. A fusion procedure, involves placing bone graft or implants where the disc was originally present, is also done along with discectomy in order to stabilize the cervical segment. This surgery is approached through the front of the neck.
Another way of doing discectomy is through the back of the neck, called Posterior Cervical Discectomy. In this procedure, only part of the disc is removed, and no spinal fusion is needed.
