Chronic foot and ankle pain can be physically and emotionally draining. If traditional treatments haven't provided the relief you need, neurostimulator implantation could be an effective option for managing your pain.
Understanding what happens before, during, and after your neurostimulator implantation can help ease your anxiety and prepare you for a successful outcome. Below, the experienced Keller TX foot doctors Alliance Foot & Ankle Specialists explain what to expect during and after this procedure.
The Neurostimulator Implantation Procedure
Neurostimulator implantation typically involves a trial period followed by permanent implantation if the trial proves successful.
What to Expect During the Trial Period
During the trial procedure, your Keller, TX, foot doctor will use local anesthesia and possibly mild sedation to keep you comfortable. Small wires called leads are inserted through a needle and positioned near the nerves that are causing your pain. These leads connect to an external device you'll wear for approximately one week.
Throughout this trial period, you'll record your pain levels and how the neurostimulator affects your symptoms. This information helps determine if a permanent implant would benefit you. Patients often report feeling a gentle tingling sensation that replaces their pain when the device is active.
Permanent Neurostimulator Implantation
If you experience a significant decrease in pain during your trial period, you'll likely proceed to the permanent neurostimulator procedure. This outpatient procedure takes about 1-2 hours and involves placing the leads and a small battery-powered generator under your skin. The generator is typically implanted in the lower back, buttock, or abdomen, depending on your comfort and anatomy.
Your foot doctor will program the device to deliver customized stimulation patterns that target your specific pain. Advanced systems may even adjust automatically based on your position or activity level.
The procedure involves small incisions, usually 2-4 centimeters long. Most patients return home the same day, ready to begin their recovery process.
Recovery Timeline and Post-Procedure Care
The first 24-48 hours after neurostimulator implantation typically involve managing mild discomfort at the incision sites. Your Keller TX foot doctor will prescribe appropriate pain medication and antibiotics to prevent infection.
What to Avoid During Recovery
During the first two weeks, you'll need to keep incisions clean and dry. You should also avoid movements that could displace the leads before they settle into position, such as:
-
Bending
-
Stretching
-
Lifting heavy objects (over 5 pounds)
-
Raising your arms above your head, as these.
Showering is usually permitted after 3-5 days, but baths, swimming, and hot tubs should be avoided for at least 3-4 weeks.
Pain Reduction Expectations
Many patients experience immediate pain relief following implantation, while others notice a gradual improvement over several weeks as swelling subsides and the body adjusts to the device. It's normal to feel some tingling or pressure around the implant sites initially.
Initial Follow-Up Appointment
You'll need to follow up with your foot doctor 2-4 weeks after the procedure. They will check your incision, remove any non-dissolving stitches, and adjust the stimulator settings if necessary. Patients can generally expect to be able to resume normal daily activities around this time, though your doctor may recommend continuing to avoid vigorous exercise until the 6-week mark.
Full Recovery From a Neurostimulator Procedure
Full recovery typically occurs within 6-8 weeks, at which point most activity restrictions are lifted. However, you may need to avoid extreme activities that could damage the device, such as contact sports or scuba diving at depths greater than 10 meters.
Programming Adjustments
Your neurostimulator requires programming to deliver personalized pain relief tailored to your specific needs. Shortly after implantation, your Keller TX foot doctor will work with you to find the most effective stimulation patterns for your pain and will take care of the initial programming.
Follow-up appointments to determine if the programming needs to be adjusted typically occur at 1 month, 3 months, 6 months, and then annually, though this schedule may vary based on your needs. During these visits, your foot doctor will fine-tune the device settings and address any concerns.
Potential Complications and When to Seek Help
While neurostimulator implantation is generally safe, understanding potential complications helps you recognize when to contact your Keller, TX, foot doctor.
-
Infection signs require immediate attention. Watch for increasing redness, warmth, swelling, drainage from incisions, or fever above 100.4°F. Most infections occur within the first month after implantation and can be effectively treated with prompt intervention and antibiotics.
-
Lead migration may occur if the stimulator wires shift position. You might notice a change in where you feel stimulation or decreased effectiveness. While not dangerous, your foot doctor will need to adjust the leads in order to restore proper pain relief.
-
Device malfunction can happen. If your stimulator stops working, delivers inconsistent stimulation, or causes uncomfortable sensations, contact your foot doctor for troubleshooting and possible reprogramming.
-
Skin erosion is rare but possible, especially in very thin patients. If the skin over your implant becomes unusually thin, red, or breaks open, seek medical attention immediately to prevent infection or device damage.
-
Battery depletion presents as gradually decreasing effectiveness. Modern devices provide ample warning before complete depletion, allowing time to schedule replacement surgery.
Long-Term Outcomes
Most neurostimulator implantation patients can expect substantial pain reduction. Success is typically measured by reduced reliance on pain medications, improved physical function, and enhanced quality of life. However, you may need to make minor lifestyle adjustments after implantation. For example, strong magnetic fields can potentially interfere with your neurostimulator. For example:
-
Airport security systems may detect your device, so carrying your implant identification card when traveling is essential.
-
You should inform health care providers about your implant before any medical procedures, including MRIs, which may require special protocols to safely perform with your device.
With proper care and management, your neurostimulator can provide years of effective pain relief, helping you return to activities you enjoy with significantly less discomfort and improved mobility.
