Spinal Cord Stimulator
Spinal Cord Stimulator Placement for Chronic Spine Pain in New Jersey.
For patients who have exhausted conservative treatments and surgical options without achieving adequate pain relief, spinal cord stimulation represents one of the most powerful tools available in spine pain management. It does not fix a structural problem. It does not remove a disc or free a compressed nerve. What it does is fundamentally change the way pain signals travel through the nervous system, and for the right patients, the results can be transformative.
A spinal cord stimulator is a small implanted device, similar in concept to a cardiac pacemaker, that delivers mild electrical impulses to the spinal cord through thin wire leads placed in the epidural space. These electrical signals interfere with the transmission of pain signals traveling toward the brain, effectively masking or replacing the perception of pain with a different sensation. Most patients describe it as a gentle tingling. With newer high-frequency systems, many patients describe it simply as an absence of the pain that was there before.
The mechanism is rooted in the gate control theory of pain, which describes how the nervous system can be modulated to reduce the experience of pain by stimulating non-pain nerve fibers that compete with and suppress pain signal transmission. Modern spinal cord stimulation systems have advanced significantly beyond the original technology. Options now include traditional low-frequency stimulation, high-frequency stimulation that produces no paresthesia,
burst stimulation, and proprietary waveforms developed by the major SCS manufacturers based on decades of clinical research.
Rishi N. Sheth, MD performs the complete SCS procedure at Spine Care New Jersey, including both the trial implantation and the permanent implant. His expertise as a fellowship-trained spine neurosurgeon means that lead placement accuracy and surgical execution reflect the same precision he brings to every procedure he performs.
Spinal Cord Stimulation Is for Patients Who Have Run Out of Standard Options, Not Given Up.
The patients who benefit most from spinal cord stimulation share a common experience. They have tried conservative treatment. Many have had one or more spine surgeries. The pain has persisted or returned. And at some point, they were told that there is nothing more that can be done.
Spinal cord stimulation is often the answer to that statement. It is not a treatment of last resort in the negative sense. It is an advanced, evidence-based intervention specifically designed for patients with chronic refractory spine pain who have not achieved adequate relief from other treatments.
The conditions with the strongest clinical evidence for SCS benefit include failed back surgery syndrome, which is persistent or recurrent pain after spine surgery. This is the most common indication for spinal cord stimulation and the one with the most extensive body of supporting research. Multiple randomized controlled trials have demonstrated that SCS outperforms repeated surgery and continued medical management for appropriately selected patients with this condition.
Complex regional pain syndrome, also known as CRPS, is another condition with strong evidence for SCS efficacy. Chronic radiculopathy that has not resolved despite decompression surgery or has not responded to conservative treatment is also a well-established indication. Refractory neuropathic pain from diabetic neuropathy, arachnoiditis, and post-herpetic neuralgia can also respond meaningfully to spinal cord stimulation.
Standard candidacy criteria for SCS include chronic pain of spinal origin for at least six months that has not adequately responded to conservative treatment, the absence of untreated structural pathology that surgical treatment could address, a psychological evaluation confirming no untreated significant psychological factors that would undermine treatment response, and no contraindications such as active infection or coagulation disorders. A properly conducted trial is the essential gateway to permanent implantation, which Rishi N. Sheth, MD discusses personally with every candidate.
When Spinal Fusion Is the Right Surgical Choice.
Spinal fusion is a significant procedure with a meaningful recovery period, and Rishi N. Sheth, MD recommends it only when it is genuinely the most appropriate treatment for the patient's specific condition. Not every spine condition requires fusion, and not every patient who has been told they need fusion elsewhere actually requires it. Dr. Sheth reviews every patient's imaging, symptoms, and treatment history before making a fusion recommendation.
The conditions that most appropriately lead to a fusion recommendation include spondylolisthesis, where one vertebra has slipped forward over the one below it, creating instability that decompression alone would leave unaddressed. Degenerative disc disease at one or more levels where the structural failure of the disc is the primary driver of pain and the disc can no longer be preserved. Spinal stenosis combined with instability or deformity, where decompression without fusion would risk destabilizing the spine further. Recurrent disc herniation at a level that has already undergone microdiscectomy, where the remaining disc is insufficient to support the spine. Spinal deformity including scoliosis and kyphosis requiring correction and stabilization. And revision surgery after a previous fusion has failed or produced adjacent level disease requiring extension of the fusion.
In all cases, fusion is recommended only after appropriate non-surgical treatment has been genuinely tried. The only exception is when clinical urgency, such as rapidly progressive neurological deficit, makes early surgical intervention the clearly correct choice.
The Trial Period Is the Most Important Step in the Entire SCS Process.
One of the most valuable features of spinal cord stimulation is something no other surgical intervention offers. Patients can try the treatment before committing to the permanent implant. The SCS trial is a temporary implantation of the stimulator leads that allows both the patient and the surgeon to evaluate how well the technology works for that individual's pain before a permanent device is placed.
The trial is performed as a minimally invasive outpatient procedure under light sedation and local anesthesia. Rishi N. Sheth, MD places the stimulator leads into the epidural space through a needle-based approach, positioning them at the spinal cord level that corresponds to the patient's pain distribution. The leads are then connected to an external trial stimulator that the patient wears during the trial period, typically seven to fourteen days.
During the trial, the patient goes home and lives their normal life while the stimulator is active. They can adjust stimulation settings using a handheld remote and keep a detailed diary of their pain levels, functional activities, and sleep quality. At the end of the trial, both the patient and Dr. Sheth review the results together. If the trial produces at least fifty percent reduction in pain, which is the standard threshold used across the SCS literature, the patient is considered a responder and the permanent implant is recommended. If the trial does not produce adequate benefit, the leads are simply removed in the office with no permanent consequences.
This trial-first approach is one of the most ethically important aspects of SCS care. A patient who undergoes the trial and finds that it does not help them has the device removed and is no worse off than before. Very few surgical interventions can make that claim.
What Happens During Permanent Spinal Cord Stimulator Implant Surgery.
For patients who complete a successful trial, the permanent implant surgery is scheduled as a planned outpatient or short-stay procedure. The permanent implant has two components. The first is the stimulator leads placed in the epidural space. The second is the implantable pulse generator, which is a small battery-powered device implanted under the skin in the flank or buttock area that powers and controls the stimulation.
Lead Placement
Rishi N. Sheth, MD places the permanent leads using the same epidural approach used during the trial, positioning them at the same spinal cord level that produced effective pain coverage during the trial period. Intraoperative fluoroscopy confirms correct lead positioning before the leads are secured in place with anchors to prevent migration. For patients who need more complex lead configurations, paddle leads are flat multi-contact electrode arrays placed through a small surgical incision. They may provide broader stimulation coverage than cylindrical percutaneous leads and are an option Dr. Sheth discusses with appropriate candidates.
Pulse Generator Placement
Once the leads are secured, a small subcutaneous pocket is created in the flank or buttock area on the same side. The implantable pulse generator is placed in this pocket, connected to the leads via an extension cable running under the skin between the spine and the generator site, and secured in the pocket. The entire procedure typically takes one to two hours.
What Patients Experience After Implant
Modern SCS systems are sophisticated programmable devices that can be adjusted non-invasively by the patient and by the clinical team as needed. Patients use a handheld remote to turn the device on and off, adjust stimulation intensity, and switch between different stimulation programs. Many current systems are MRI-compatible under specific conditions, which is an important practical consideration for patients who may need spinal imaging in the future. Battery life varies by system and usage, with rechargeable systems offering significantly longer generator life than non-rechargeable options.
What to Expect After Spinal Cord Stimulator Implant Surgery.
Recovery after SCS implant placement is relatively straightforward compared to most spine surgical procedures, largely because the leads are placed without significant disruption of the bony or muscular structures of the spine.
In the first week after surgery, activity restrictions focus on avoiding bending, twisting, and stretching movements that could displace the newly placed leads before they have had time to become anchored by scar tissue. Patients keep the implant site dry and clean, avoid heavy lifting, and limit strenuous physical activity during this early phase.
Return to light daily activities and sedentary work typically occurs within one to two weeks. More physically demanding activity is restricted for four to six weeks while the leads stabilize in position and the generator pocket heals.
The programming process begins shortly after implant and continues through a series of follow-up appointments over the first weeks and months. Finding the optimal stimulation parameters for each patient is an iterative process. Patients should expect that settings will be adjusted multiple times as the nervous system adapts to the stimulation and pain patterns are better characterized. Most patients reach their optimal programming within the first two to three months after implant.
The success of SCS is not defined purely by the implant procedure itself. The quality of the ongoing programming relationship between the patient and the clinical team significantly influences long-term outcomes. Dr. Sheth and the Spine Care New Jersey team manage this relationship personally throughout each patient's SCS journey.
Fusion Expertise Across Every Approach, in One Dedicated Practice.
Spinal fusion is one of the procedures where the full range of a surgeon's training and certification is most relevant. Different patient anatomies and conditions favor different fusion approaches, and a surgeon who is fluent in only one or two techniques is limited in what they can offer patients whose anatomy or pathology is better suited to an alternative approach.
Rishi N. Sheth, MD is trained and certified in the full range of lumbar fusion approaches, including TLIF, ALIF, DLIF, and posterior lumbar fusion, as well as cervical fusion techniques. His DLIF certification is a specific credential that relatively few spine surgeons in New Jersey hold, and it gives patients access to a lateral approach that often allows faster recovery than posterior techniques. His Mazor robotic certification ensures that instrumentation placement across all fusion types is performed with computer-guided precision that reduces hardware complications and revision rates.
Patients who have been evaluated elsewhere and told they need fusion are welcome to bring their imaging to Spine Care New Jersey for a second opinion. Dr. Sheth will review the case honestly and tell patients whether fusion is genuinely indicated, which specific approach is most appropriate for their anatomy, and what alternatives, including disc replacement for eligible patients, might be worth considering before committing to a fusion.
Common Questions About Spinal Cord Stimulator Placement at Spine Care New Jersey.
A spinal cord stimulator is a small implanted device that delivers mild electrical impulses to the spinal cord through leads placed in the epidural space. These impulses interfere with pain signal transmission between the spine and brain, reducing or masking the perception of chronic pain. Modern systems offer multiple stimulation modes including traditional low-frequency, high-frequency, and burst stimulation. A trial period of seven to fourteen days allows patients to evaluate how well stimulation controls their pain before committing to the permanent implant.
Good candidates for SCS have chronic refractory spine pain, most commonly failed back surgery syndrome, persistent radiculopathy, or complex regional pain syndrome, that has not responded adequately to conservative treatment or surgery. The standard threshold is at least six months of chronic pain without adequate relief from other treatments. A psychological evaluation and a successful trial producing at least fifty percent pain reduction are required before permanent implantation. Rishi N. Sheth, MD personally evaluates every SCS candidate and performs both the trial and permanent implant at Spine Care New Jersey.
The SCS trial is an outpatient procedure performed under light sedation and local anesthesia. Stimulator leads are placed in the epidural space through a needle-based approach and connected to an external trial device the patient wears at home for seven to fourteen days. During this period patients adjust stimulation settings and track pain relief. If pain is reduced by at least fifty percent the permanent implant is recommended. If the trial is unsuccessful the leads are removed with no permanent consequences to the patient.
Permanent SCS implant surgery places the trial leads permanently in the epidural space using fluoroscopic guidance, anchors them to prevent migration, and implants a small battery-powered pulse generator under the skin in the flank or buttock area. The leads and generator are connected by an extension cable running under the skin. The procedure takes one to two hours and is typically performed as an outpatient or short-stay procedure. Patients go home with a handheld remote to control stimulation settings and return for programming adjustments over the following weeks.
Most patients return to light daily activities and sedentary work within one to two weeks after SCS implant surgery. Bending, twisting, and heavy lifting are restricted for four to six weeks while the leads stabilize in position. Optimal stimulation programming is typically achieved within the first two to three months through a series of follow-up adjustments. Long-term SCS success
depends on both the quality of the implant procedure and ongoing programming, both of which Rishi N. Sheth, MD manages personally at Spine Care New Jersey.
