Spinal cord stimulation (SCS) is an innovative medical treatment designed to alleviate chronic pain by sending electrical impulses to the spinal cord. This therapy is often considered when other pain management methods, such as medications or physical therapy, have failed to provide sufficient relief. In this article, we will explore the mechanisms, benefits, procedure, risks, and advancements related to spinal cord stimulators and share patient experiences and testimonials.

Key Takeaways

  • Spinal cord stimulation delivers electrical impulses to the spinal cord, which helps mask pain signals before they reach the brain.
  • There are various types of spinal cord stimulators available, each tailored to different conditions and patient needs.
  • The procedure for implanting a spinal cord stimulator involves preoperative preparations, a surgical procedure, and postoperative care.
  • While spinal cord stimulators offer significant benefits like pain relief and reduced medication use, they also come with potential risks and complications.
  • Advancements in spinal cord stimulation technology continue to improve the effectiveness and safety of these devices, offering hope for better pain management solutions in the future.

Understanding Spinal Cord Stimulation

Spinal cord stimulation (SCS) is a treatment designed to help manage chronic pain when other treatments have failed. It involves a small device that delivers electrical pulses to the spinal cord, masking pain signals before they reach the brain. This therapy is particularly useful for those suffering from chronic back, leg, or arm pain.

Mechanism of Action

The spinal cord stimulator works by placing a stimulating electrode over the spinal cord. This electrode sends electrical pulses that interfere with the pain signals traveling to the brain. By blocking these signals, the device helps reduce the sensation of pain. This method is especially beneficial for patients whose pain cannot be managed through medication or physical therapy.

Types of Spinal Cord Stimulators

There are several types of spinal cord stimulators available, each with unique features:

  • Conventional Implantable Pulse Generator (IPG): This device has a battery that needs to be surgically replaced every few years.
  • Rechargeable IPG: This type has a battery that can be recharged externally, reducing the need for replacement surgeries.
  • Radiofrequency Stimulators: These are powered by an external antenna and are typically used for more complex cases.

Conditions Treated

Spinal cord stimulators are typically used to treat chronic pain conditions that have not responded to other treatments such as medication or physical therapy. Some of the conditions include:

Benefits of Spinal Cord Stimulators

Pain Relief

Spinal cord stimulators are a treatment option that may offer relief for people living with pain that isn’t responding to more common forms of treatment. The likelihood of success from this treatment is also greater than in years past, thanks to advances in technology, surgery techniques, and science’s understanding of the nervous system. While there are still some drawbacks and risks of complications, the benefits of spinal cord stimulators mean more people can live with lower pain levels without relying on stronger, habit-forming medications.

Reduction in Medication Use

Spinal cord stimulation therapy masks pain signals before they reach the brain. A small device, similar to a pacemaker, delivers electrical pulses to the spinal cord. It helps people better manage their chronic pain and reduce their use of opioid medications. This is especially beneficial for those who have not experienced sufficient pain relief with medications, less-invasive therapies, or prior surgeries.

Improved Quality of Life

Each patient is different, but generally, people who benefit the most from spinal cord stimulation are those who:

  • Have not experienced sufficient pain relief with medications, less-invasive therapies, or prior surgeries
  • Do not have psychiatric disorders that would decrease the effectiveness of the procedure

They understand the importance of bringing the most advanced and effective therapies to their patients, ensuring a care plan that’s tailored to each individual’s needs and conditions.

The Procedure for Implanting a Spinal Cord Stimulator

Preoperative Preparations

Before the procedure, your doctor will discuss the process and answer any questions you may have. You might need to stop taking certain medications and follow specific instructions to prepare for the surgery. It’s important to follow these guidelines closely to ensure a smooth procedure.

Surgical Procedure

The implantation involves two main steps: a trial and the permanent implantation. During the SCS trial, your doctor will use an epidural needle to inject a lead with electrodes into the epidural space between your vertebrae and spinal cord. If the trial is successful, a second procedure will be scheduled to implant the pulse generator or battery permanently. This involves placing the generator under the skin and securing the electrodes with sutures to minimize movement.

Postoperative Care

After the surgery, you will have follow-up appointments to monitor your healing and adjust the settings of the spinal cord stimulator. Initially, most devices need slight adjustments, but the settings usually stabilize after a few weeks. Regular check-ups are crucial to ensure the device is working correctly and to address any issues promptly.

Potential Risks and Complications

Spinal cord stimulation is generally safe, but like any surgery, it comes with potential risks and complications. It’s important to be aware of these before deciding to undergo the procedure. Always discuss these risks with your doctor to make an informed decision.

Common Side Effects

Common side effects of spinal cord stimulation include:

  • Pain at the implant site
  • Infection
  • Bleeding
  • Headache

These side effects are usually temporary and can be managed with proper medical care.

Serious Complications

While rare, serious complications can occur. These include:

  • Device malfunction
  • Lead movement
  • Epidural hemorrhage
  • Spinal cord compression
  • Paralysis

If you experience any of these symptoms, seek medical attention immediately.

Managing Risks

To minimize risks, follow these steps:

  1. Choose a qualified and experienced surgeon.
  2. Follow all preoperative and postoperative instructions.
  3. Keep all follow-up appointments.
  4. Report any unusual symptoms to your doctor right away.

At the Arizona Pain and Spine Institute, Dr. Khan and Dr. Ryklin are dedicated to ensuring the highest standards of care to help manage and mitigate these risks.

Patient Selection Criteria

Patients selected for spinal cord stimulation (SCS) usually have had chronic debilitating pain for more than 3 months in the lower back, leg (sciatica), or arm. They also typically have had one or more spinal surgeries. Spinal cord stimulation is a proven therapy approved for patients with certain types of back, leg, foot, or upper limb pain. You may be a candidate for SCS if:

  • You have chronic pain that has not responded to other treatments.
  • You have had previous spinal surgeries without significant relief.
  • You are not a candidate for further major spine surgery.
  • You do not have untreated depression or drug addiction.

Not everyone is a good candidate for SCS. Some conditions may prevent you from being eligible, such as:

  • Active infections
  • Severe psychiatric disorders
  • Bleeding disorders
  • Pregnancy

Before considering spinal cord stimulation therapy, patients must go through a thorough screening process. This process includes:

  1. In-depth history and physical examination to rule out medical conditions that may increase the risk of complications.
  2. Routine laboratory evaluation based on the patient’s medical history and the type of anesthesia that will be used during the procedure.
  3. Relevant spine imaging studies (e.g., X-ray, CT, MRI) to assess the potential for technical difficulties.
  4. Psychological screening, often required by insurance companies for approval of payment.
  5. For patients with pre-existing cardiac comorbidities, a consultation with a cardiologist and a compatibility test is often necessary.

At Arizona Pain and Spine Institute, Dr. Khan and Dr. Ryklin are dedicated to ensuring that each patient receives a comprehensive evaluation to determine the most appropriate treatment plan. They understand the importance of bringing the most advanced and effective therapies to their patients, ensuring a care plan that’s tailored to each individual’s needs and conditions.
