A herniated lumbar disc can push on spinal nerves and cause severe, shooting leg pain, numbness and/or weakness. A percutaneous disc removal (PDR) can remove a portion of the herniated disc that is compressing spinal nerves through a small incision in the skin. This minimally invasive approach uses a much smaller incision than traditional open spinal surgeries and avoids damage to the low back muscles. In some cases, removing part of the herniated disc in a partial discectomy procedure can also prevent the disc from irritating the nerve.
