It is the goal of this paper to expand on Franklin's previous report and give a comprehensive look at current complications of spinal cord stimulation [24]. Around the world some 34,000 patients undergo spinal cord stimulator implants each year. Find out how spinal cord stimulation (SCS) or dorsal root ganglion (DRG) therapy can help people with chronic pain live fuller lives - and see firsthand what life is like with an implanted neurostimulator. 5 Pope JE, Deer TR, Falowski S, Provenzano D, Hanes M, Hayek SM, Amrani J, Carlson J, Skaribas I, Parchuri K, McRoberts WP. A sterile nonocclusive dressing is applied over the wound and should remain undisturbed for 4872 hours if the dressings are not grossly soiled; at this point, if the wounds are dry and there is no seepage, the patient may shower without disturbing the wounds. A spinal cord stimulator uses small, thin wires implanted in your epidural space (between the spinal cord and the vertebrae) to deliver a mild electrical current. This discussion should be documented and witnessed. The most common problems seem to revolve around migration of the leads in the spine, unwanted stimulation or discharge, including some people getting shocked, overheating and burning around the battery site, nerve damage and infection. Tim Betler, UPMC and University of Pittsburgh Schools of the . The FDA uses MDRs to monitor device. 2021 Feb 9. In cases where the CT is inconclusive, the leads should be urgently removed and an MRI should be obtained [1013]. Also notice a change in the pelvic tile or pelvic incidence: For many patients we see, who have issues of chronic back pain and neurological or radiculopathy issues causing pain to move into the legs or arms, they come into the first visit us with an understanding that something is wrong with the curve of their spine. These devices come in several types, and can be an alternative to other forms of treatment, such as opioids, which may become addictive. The Spinal ligament repair injection treatment option Prolotherapy, Platelet Rich Plasma Therapy in combination with Prolotherapy, During the first 12 months, patients treated with SCSs had higher odds of chronic opioid use compared with patients treated with conventional medical management but lower odds of epidural and facet corticosteroid injections, radiofrequency ablation, and spine surgery. I never seemed to get out of the recovery period from the Spinal Cord Stimulation system surgery. In addition to epidural bleeding, vigilance is required to diagnose infections of the spinal structures. Men accounted for 41% of the study group, women 59% of the study group. 13Hussein M, Hussein T. Effect of autologous platelet leukocyte rich plasma injections on atrophied lumbar multifidus muscle in low back pain patients with monosegmental degenerative disc disease. A January 2020 study (4) from leading Italian university neurological surgery researchers is titled: Surgical Back Risk Syndrome and Spinal Cord Stimulation: Better Safe Than Sorry. The paper was published in the journal, World Neurosurgery. and Terms of Use. Thoracic kyphosis is a hunchback situation in the mid spine. In addition, there are some risks that are specific to the spinal cord stimulator. Medical Xpress is a part of Science X network. It is a pelvic x-ray showing a patients spinal cord stimulator and the spinal fusion screws. A January 2022 study in the Journal of Clinical Medicine (14) writes: While paresthesia-based (nerve or burning pain) Spinal Cord Stimulation has been proven effective as a treatment for chronic neuropathic pain, its initial benefits may lead to the development of Spinal Cord Stimulation Syndrome. The researchers define this as a lessening beneficial effect of treatment over time. Specifically, Spinal Cord Stimulation systems are used for people who have pain after spinal surgery or spinal issues in which an additional surgery would be risky or come with a high expectation of surgical failure. [Google Scholar] A seroma is a noninfectious process that involves the seepage of serum from the tissues of the pocket into the area surrounding the generator. When the staples or sutures are removed, the wound should remain dry for approximately 24 hours to allow the holes and tracts left by the closure to seal. Aspiration can lead to introduction of infection and the risk to benefit ration should be considered. We see the people who have had their Spinal Cord Stimulation systems removed because they were not successful. Lets also point out that Spinal Cord Stimulators suppress pain symptoms, they are a surgically implanted form of painkillers. Identify the news topics you want to see and prioritize an order. Pain can be treated by conservative measures such as lidoderm patches, injections of neuroma or cushioning of hardware sites. The most common neurological insult from SCS is inadvertent dural puncture. The patient to whom this x-ray belongs had a history of multiple spinal surgeries, cortisone injections, and the implantation of a spinal cord stimulator. Dorsal root ganglion stimulator. The risks of the permanent device have the same acute worries, but there are additional risks associated with the surgical implantation and the long term use of the system. SICOT-J. A November 2020 study published in the Journal of Pain Research (6) suggested better results in managing Spinal Cord Stimulation failure if the patient received a higher-frequency SCS. . Therapy consists of a short trial with a percutaneous implantation of neurostimulator electrode . SCS was associated with higher costs, and SCS-related complications were common.. It is her story. Overall, 226 of 1260 patients (17.9%) treated with SCS experienced SCS-related complications within 2 years, and 279 of 1260 patients (22.1%) had device revisions and/or removals, which were not always for complications. In rare cases, this may require explanting of the device. When invading the epidural space with a needle or rigid lead, the chance exists to puncture a blood vessel. In some settings, the amount of fibrosis does not appear to cause any change in the patient's condition and does not require treatment [20]. Spinal cord stimulation is effective for chronic back pain. [Google Scholar] They send a mild electrical current to the spinal cord to relieve chronic pain. Quigley DG Arnold J Eldridge PR et al. However, despite the demonstrated benefits of spinal cord stimulation, some patients have the device removed. Another major concern is the significant placebo effect, which makes the true therapeutic response difficult to judge.. I have had two back surgeries, the last in 2016. The 15 patients who had their stimulators removed quickly, in a median time of 2 months, typically suffered an acute post-surgical complication, such as infection. The purpose of this study was to compare low and high-frequency devices and to assess their outcomes in helping patients. 1. The North American Neuromodulation Society issued a statement about spinal cord stimulation this fall. Much like the history of electrical therapies for the treatment of disease, spinal cord stimulation (SCS) has seen a major evolution since it was first reported in the literature four decades ago. The lead volume itself may create further narrowing if the patient's spine becomes stenotic at the level of implant [21]. Pain and Therapy. Risk factors for epidural hematoma include drugs that effect clotting, coexisting liver disease, blood disorders, difficult lead placement with multiple passes, surgical lead placement, and extensive bony insult in placing the lead. They do not repair spinal damage. Diagnosis is made by plain films, computer analysis of impedance, and physical exam. Explore the inspiring personal stories of people who've reclaimed their lives from chronic pain. However, the complications are rare. The risks of the procedure are small compared with repeat back surgery, and outcomes may be more effective compared with other chronic pain therapies as measured by patient satisfaction and cost-effectiveness, [2830]. At 12-month follow-up, 81.3% preferred to keep tonic stimulation (a constant stream of pulses) in their waveform portfolio. By delivering electrical pulses that interrupt pain signals from the affected area to the brain, this device can improve patients' quality of life and reduce their need for medication. The highest risk for bleeding is in the first 24 hours. The use of consulting doctors should be considered to reduce, treat, and rehabilitate patients who have had complications. The consensus was that an MRI is not required of the thoracic spine prior to a lumbar thoracic implant. [Google Scholar] For more information on the combined use of PRP and Prolotherapy please see Prolotherapy treatments for lumbar instability and low back pain. Limitations of Spinal Cord Stimulators People still take opioids. In cases where a postdural puncture occurs, there appears to be no long-term sequelae and it does not appear to affect long-term outcomes. The most common organisms for infection are Staphylococcus aureus, and other gram positive organisms. HFX Spinal Cord Stimulation is a nondrug, FDA-approved, treatment option for long-term chronic pain relief. [Google Scholar] The patient and implanting doctor should also discuss the different methods of placing a permanent system through a percutaneous approach similar to the trial or the surgical lead approach which involves a more extensive surgical technique. He reported that in his experience, the relief provided was often overridden by complications including skin burns and pain with increasing current and voltage. The differential diagnosis includes seroma or allergic reaction to the device. The researchers in this study wanted to know why. 2022 Jan 4;5(1):e2145876-. If the patient has had staples or sutures, removal could occur anywhere from 7 to 10 days depending on the general health of the patient, body habitus, and condition of the wound. CT = computed tomography; MRI = magnetic resonance imaging; IV = intravenous; CBC = complete blood count; emg = electromyograph; ncs = nerve conduction studies; ID = infectious disease specialist. Mayfield Clinic. There are several benefits and risks to consider when deciding . Other options include surgical lead revision, or revision to a more complicated system [2527]. It is in these patients that implantable devices spinal cord stimulation systems or targeted drug delivery (TDD) devices are usually recommended. This is achieved through our various spinal curve correction programs and Prolotherapy. VIII. Spinal cord stimulation syndrome conversion using adapters appears promising as a salvage solution, with an emphasis on paresthesia recapturing enabled via spatial retargeting.. In widely spaced dual lead octapolar systems, the leads may be reprogrammed to capture other fibers and to salvage a good outcome. In research from Harold Wilkinson MD, published in the medical journal Pain Physician, (12) Dr. Wilkinson looked at difficult back pain cases, Of the patients studied, 86% of patients had undergone prior lumbar spine surgery and all were referred for neurosurgical evaluation for possible surgery, to see is simple dextrose Prolotherapy would be of benefit. The same drugs that I was on before the implant. The Advanced Bionics PRECISION Spinal Cord Stimulation System has not been marketed in the United States or any foreign country. The researchers also noted that a large subset of patients who experienced spinal cord stimulator failure also experienced high rates of major depression, anxiety, physical or sexual abuse, post-traumatic stress disorder, or drug and/or alcohol abuse. Due to the inherent difficulty of identifying complications by peer review and closed claim analysis, the incidence of complications with SCS is unknown. Both stimulation strategies led to a large, sustainable, clinically relevant pain suppression and improvement in quality of life.. A spinal cord stimulator implant is one of two last resorts, something to throw at my vast, diffuse, crushing back and neck pain. These patients were given salvage therapy. The doctors replaced the patients low-frequency SCS with a higher-frequency SCS. Prevention of this problem may include the use of a 30 angle for needle entry, placement of the lead at a minimum of two vertebral bodies, anchoring of the system to the spinal ligaments, and the presence of a strain relief loop at the site of lead entry to the ligament, and at the generator site. Spinal cord stimulators are a type of neuromodulation in other words, they work by preventing pain signals from reaching the brain. Journal of clinical medicine. Spinal Cord Stimulation (SCS) is a theoretically principled treatment with a substantial and supportive evidence base that has been used for the treatment of pain since 1967. 2022 Jan;11(1):272. The incidence of these events is less than 1 in 1,000, and most infectious problems do not involve the neuraxis [15]. But the curvature of the spine is a complex problem and many of our patients who come in have reduced their understanding of this problem, and rightfully so, to how it impacts their daily lives. This may be caused by excessive tissue trauma, such as aggressive sharp dissection, excessive use of cautery, or forceful blunt retraction. Journal of Pain Research. These, however, are not the people we usually see in our practice. These patients, like those affected by failed back surgery syndrome (FBSS), may become unresponsive to medical conservative treatment and their quality of life could be easily compromised. These findings lead the researchers to suggest that in this group targeted drug delivery should be recommended ahead of spinal cord stimulation. The accuracy of these stated rates are difficult to interpret because of the variability of the populations involved in the different studies. It is strategically aimed to reduce the unpleasant sensory experience of pain and the consequent functional and behavioural effects that pain may have. Learn More. Recentresearch says that Platelet-Rich Plasma (PRP)represents an additional approach, as it has shown some promise in bone regeneration, and should be explored for its potential role in limiting spinal fusion surgery failures. This problem may have a significant effect on the ability to program the system. 17 Dhruva SS, Murillo J, Ameli O, Morin PE, Spencer DL, Redberg RF, Cohen K. Long-term Outcomes in Use of Opioids, Nonpharmacologic Pain Interventions, and Total Costs of Spinal Cord Stimulators Compared With Conventional Medical Therapy for Chronic Pain. North RB Calkins SK Campbell DS et al. When dual octapolar leads are used, in most cases the normal shifting of a percutaneous lead can be addressed with changing the pulse width or the position of the cathode. Turner analyzed the available evidence-based studies over the past decade and found an overall complication rate of 34%, a complication rate leading to surgical revision in 23%, and a serious complication rate at less than 1% [8]. During spinal cord stimulation, a device that delivers the electrical signals is implanted in the body through a needle placed in the back near the spinal cord. If weakness develops, a vigilant search should occur for the cause of this problem. Patient education should occur during this period including the expectations of the therapy, expected outcomes, and common risks. In regard to pain relief and neurological diseases, early reports were optimistic for the use of this treatment for headaches, joint pain, hysteria, and depression. After your spinal cord stimulator surgery, you will have staples that need to be removed. If the problem does not resolve in a reasonable time, an incision and drainage must be performed [21] (See Figure 4). The labels on spinal cord stimulators are clear on the need for trial simulation periods: Materials from Abbott, Boston Scientific, Medtronic and Nevro state their devices are only for use in patients who received effective pain relief during trial stimulation. If you are reading this page, it is likely you have been recommended to a Spinal Cord Stimulation system instead of a traditional spinal surgery or you have had your system removed and you are seeking other options beyond increasing pain medications and learning behavioral or coping skills. Treatment includes hydration, caffeine, and rest. Infections can include meningitis, epidural abscess, and discitis. 1 Spinal cord stimulation (SCS), including BurstDR stimulation, relieves pain that's more broadly felt in the trunk and/or limbs. Since the therapy first entered routine . Neuromodulation: Technology at the Neural Interface. Diagnosis is made by CT myelogram. In most cases, the generator should be at a depth of 2 cm or more. Further work revealed that electricity is involved in muscle movement, neurological function, and pain perception. A May 2022 study published in the journal Neuromodulation (3) wrote: Spinal cord stimulation has found its application in chronic pain treatment, with failed back surgery syndrome as one of the most important indications. In a 10.6 year follow up of long-term spinal cord stimulation in patients with failed back surgery, 78.5% of the patients were satisfied and noted a significant pain reduction of an average three points on the 0 10 Numeric Rating Scale. In the 11 of the 27 patients in this study with loss of pain coverage area, spinal cord stimulation adaptions results in efficacy on pain intensity of (36.89%) and were accompanied via paresthesia coverage recovery (55.57%) and pain surface decrease (47.01%). This is a complication of surgery, spinal instability. The spinal cord stimulator device is comprised of two parts: thin wires, or electrodes, and a generator, which is like a pacemaker. A similar principle utilizes the central nervous system and the peripheral nervous system stimulation in deep/cortical brain stimulation and . You control the current intensity and timing. Timothy R. Deer, MD, C. Douglas Stewart, PA/C, MBA, Complications of Spinal Cord Stimulation: Identification, Treatment, and Prevention, Pain Medicine, Volume 9, Issue suppl_1, May 2008, Pages S93S101, https://doi.org/10.1111/j.1526-4637.2008.00444.x. If the patient has one lead, or closely spaced leads that cover a finite area of the spinal cord or nerve, the leads may require surgical revision. Treatment includes immediate treatment of the burn, consultation of a plastic surgeon, and eventual revision of the device. A Comparison of 1000 Hz to 30 Hz Spinal Cord Stimulation Strategies in Patients with Unilateral Neuropathic Leg Pain Due to Failed Back Surgery Syndrome: A Multicenter, Randomized, Double-Blinded, Crossover Clinical Study (HALO). When possible, the patient should be removed from any drug that effects clotting for a time interval sufficient to normalize the effect on bleeding. Stereotactic and Functional Neurosurgery.:1-7. 2020 Jan 1;133:e658-65. Consideration should be given to changing the manufacturer of the device that is implanted in the deeper tissues or to a system that does not require recharging. Step 4) The patient is then woken up in order . Epidural fibrosis can occur with an indwelling lead in place. Spinal cord stimulation uses the power of a device known as a pulse generator. Spinal cord stimulation consists of applying an electrical stimulus to the spinal cord to relieve chronic pain. The indications for the procedure should also be documented for help in insurance approval and reimbursement. Treatment is by surgical revision and by adding new technology to reduce the impact of future fractures. In some instances, the investigator may be more experienced than the typical implanter resulting in better overall outcomes, or the outcomes may be significantly worse because of the severity of the patient disease states and the demands of a teaching environment. In another analysis, Kumar found lead complication rates to be 5.3%, a low infection rate of 2.7%, and an epidural fibrosis rate of 19% [9]. A May 2022 study from a team of European researchers (16) analyzed retrospectively the long-term outcomes of spinal cord stimulation treatment on predominant radicular pain. It is at this junction we want to stimulate repair of the ligament attachment to the bone. During months 13 to 24, there was no significant difference in chronic opioid use, epidural and facet corticosteroid injections, radiofrequency ablation, or spine surgery between SCS use and conventional medical management. [Google Scholar] Why the black crayon lines? Following Prolotherapy treatments she had the SCS removed. Neither your address nor the recipient's address will be used for any other purpose. Time is valuable to improving the chances of a full recovery. Wound closure can best be achieved with an absorbable suture in the deeper tissues and also in the subcuticular layers. This article gives an overview of the identification, treatment, and follow-up care of patients suffering complications. www.ncbi.nlm.nih.gov/pmc/articles/PMC4938148/. The researchers in this study examined patients who succeeded with SCS and those who failed SCS and consequently proceeded to targeted drug delivery. 2019;6(3):81. Diagnosis of infection includes erythema, rubor, and drainage of purulent material. Please select the most appropriate category to facilitate processing of your request, Optional (only if you want to be contacted back). The device may be replaced in 12 weeks if the infection is eliminated. In patients with surgical leads, the problem is usually self-limited because of the leads' unidirectional current delivery. The use of conscious sedation with monitoring is helpful to enable the patient to tolerate the procedure while also remaining conversant and alert to reduce the risk of neurological damage. The researchers concluded: In this large, real-world, comparative effectiveness research study comparing SCS and conventional medical management for chronic pain, SCS placement was not associated with a reduction in opioid use or nonpharmacologic pain interventions at 2 years. 2022 May 14. Never attempt to change the orientation or "flip" (rotate or spin) the implant. The device consists of a stimulating wire or "electrode" or connected to control unit or "generator.". Lead migration is another complication that should be considered with device failure. (7) The title of this paper is: Spinal cord stimulation failure: evaluation of factors underlying hardware explantation., Spinal cord stimulation has been shown to improve pain relief and reduce narcotic analgesic use in cases of complex refractory (difficult to treat) pain syndromes. 2. SCS is best suited for neuropathic pain but may have some limited value in other types of nociceptive severe, intractable pain. Primary reasons for hardware removal were: electrode failure due to migration (14%). In this article, we discussed the failure of spinal cord stimulators. Expectations should be discussed and the risk of complications should be outlined. Take the Quiz!
