Nucleoplasty

Percutaneous disc nucleoplasty is a minimally invasive procedure, which may provide long term relief of back pain caused by various forms of disc herniation.  This procedure involves the careful placement of a needle into the involved intervertebral disc.  Radiowave therapy is then introduced through the needle in order to ablate and coagulate the gel portion of the disc that reduces the disc herniation.  In successful cases, the reduction of the protruding nuclear material reduces the amount of pressure within the intervertebral disc and the pressure placed upon adjacent nerve or nerves by the outer portion of the disc.

Spinal Cord Stimulator

Spinal cord stimulation is a therapy with proven results in patients who have severe neck, mid-back or low back which failed to respond to more conservative attempts to reduce pain.  The procedure is performed via placement of a small system beneath the skin that sends electrical impulses to the spinal cord overlying the region subserving the pain.  Patients who have a spinal cord stimulator often describe a non-painful tingling sensation in the region of stimuli.  Patients can control the delivery and intensity of electrical stimulation to the spinal cord.

The stimulator is an electrical device that a physician may implant to help control pain that has not been controlled by pain medicines (analgesics) and by a TENS unit.  A stimulator box is attached to a wire with an electrode on the end.  The electrode is placed over the surface of the spinal cord.  The settings on the box can be changed until the best result is obtained. 

Intrathecal Drug Delivery

Intrathecal drug delivery can be applied in patients who have failed more conservative approaches.  Patients who have cancer pain may benefit from this form of treatment.  An intrathecal delivery system delivers medications into the fluid surrounding the spinal cord, thus delivering the medication to the specific area where the pain signals travel.  This form of drug delivery can help to effectively reduce pain when oral approaches have failed.  The primary benefit of this form of drug delivery is that it requires a much lower dose of medication compared to pills to effectively achieve pain relief.  Subsequently, the side effects of mediation may be minimized.  The system is comprised of a pump that is placed into the abdomen.  The pump system delivers medicine at a controlled pre-programmed rate via the insertion of a small plastic catheter (tube).

The Artificial Disc

Currently the primary surgical procedure for treating a diseased and painful disc is surgical fusion.  This procedure requires that the biological disc be removed and replaced with a bone graft that is put between two adjacent vertebrae.  A surgical spinal fusion is usually not considered unless there is confirmed disc-related pain that is disabling and unresponsive to other more conservative treatments including chiropractic care.  The pain should persist for more than 6 months. 
The main objective of replacing a biological disc with an artificial disc is to relieve intractable pain and to help maintain or restore function.  An artificial disc may be used to help reconstruct an area of the spine that has been structurally altered rendering it unstable. The procedure is being developed as an alternative to surgical spine fusion.
