Symptoms of a Spinal Cord Stimulator Infection

A spinal cord stimulator is an electronic device implanted next to the spine to help treat chronic back pain. The device, also called a dorsal column stimulator, has wires that deliver a low-level electrical current directly to the spinal cord area. The technology has been in use for more than 30 years and is about the size of a pacemaker. Infection is one of the dangers of an implanted spinal cord stimulator.

  1. Infection

    • While spinal cord stimulator surgery is minimally invasive because it is placed just beneath the skin though a small incision, problems still can occur. Infection can take place in or around the incision, spinal cord or vertebra.

      Seroma is a condition that affects the area around an implanted device. Fluids can collect in the area and may require surgical drainage. If the seroma becomes infected, the device must be removed.

    After Surgery

    • Following surgery, some swelling and bruising is natural. Ice packs may provide relief from the pain, but anti-inflammatory drugs like ibuprofen (Advil), aspirin and naproxen sodium (Aleve) may be discouraged because they may cause bleeding.

    What to Look For

    • Carefully watch the incision area for redness, excessive swelling, separation of the wound edges or any kind of drainage that might indicate an infection. Report a fever to your doctor immediately, as it's a common indicator that the body is fighting an infection.

    How to Avoid Infection

    • Follow your doctor's instructions. Keep dressings clean, dry and changed often. Showering is allowed, but bathing or any kind of submerging , including hot tubs and swimming pools, is not advisable for at least four weeks. Wearing loose clothing allows air circulation and avoids pressure on the area.

    Is It Worth the Risk?

    • While there is no guarantee that the device will alleviate your pain, patients report an average of 50 to 70 percent relief from chronic pain, making spinal cord stimulators a viable pain management strategy. Complications are uncommon, making the surgical risk low. A spine specialist will determine if you're a good candidate for surgery.
