Spinal Cord Stimulator Implant

Spinal cord stimulation (SCS) is used to relieve chronic low back and sciatic pain. It uses electrical impulses to prevent pain signals from being perceived by the brain.

SCS candidates include people for whom conservative treatments have failed and surgery is not likely to help.

STEP 1.

Trial Implantation

Under local anesthetic one or more insulated wire leads are inserted near the spinal cord by a needle or through a small incision. This is connected to a temporary stimulator. It will be used for several days or weeks to determine if SCS will help the patient. If pain decreases by 50 percent during the trial period, the system may be permanently implanted.

STEP 2.

Permanent Implantation

This second procedure is usually done under general anesthesia. The temporary leads are removed and, through a needle or incision, permanent leads are implanted.

STEP 3.

Receiver Implantation

The receiver is implanted under the skin in the buttocks or abdomen. The leads are then connected to the receiver. The power source for the implant may be internal (pulse generator) or external (transmitter and antenna).

END OF PROCEDURE:

The implant's electrical impulses are programmed with an external unit.

After surgery, patients may experience mild discomfort and swelling at the incision sites for several days. Over time, leads may move or become damaged from strenuous activity and require repositioning or replacement.
