Spinal cord stimulator (assessment and implant)

What is a spinal cord stimulator?

A spinal cord stimulator (SCS) is an implanted device used for certain kinds of long-term nerve pain that have not responded to other treatments. Thin wires (leads) are placed in the space around the spinal cord, and a small battery (pulse generator) sends mild electrical pulses along them. For some people this changes how pain signals are felt, easing the pain.

It is not a first treatment and it is not for everyone. NICE recommends it only for adults with nerve (neuropathic) pain that has lasted at least six months and stayed severe despite proper conventional treatment, after assessment by a specialist pain team — and only if a trial of stimulation has clearly helped. It is not recommended for pain caused by poor blood supply (ischaemic pain) except in research.

Crucially, it is done in two steps: a trial with temporary leads first, and a permanent implant only if the trial works. A stimulator reduces pain rather than curing it — many people get worthwhile relief, but not everyone responds, and it is surgery with real risks such as infection, lead movement and the need for further operations. It works alongside, not instead of, self-management and rehabilitation.

Types & techniques

There isn't one single operation. The right approach depends on you — which is something to discuss with your surgeon.

Spinal cord stimulation versus other options

A stimulator is considered only after suitable conventional treatments have not given enough relief, and after specialist assessment.

Preparing for your surgery

• Be assessed by a specialist pain team (a multidisciplinary team), which usually includes psychological assessment, as recommended by NICE.
• Make sure you understand this is a two-step process: a trial first, and a permanent implant only if the trial clearly helps.
• Tell the team about all medicines, especially blood thinners, which must be managed before each procedure.
• Mention any infection, skin problems over the implant sites, or a weakened immune system, as these raise infection risk.
• Discuss your expectations honestly — the aim is meaningful pain reduction and better function, not a cure.
• Tell them about any other implanted device (such as a pacemaker) and plans for future MRI scans.
• Plan for restricted movement and time off after the implant while the leads settle, and arrange help at home.
• Keep a pain and activity diary so the trial and later results can be judged honestly.

What happens

Treatment happens in two stages. In the trial, you usually lie awake but sedated, with local anaesthetic, so you can describe where you feel the stimulation. Using X-ray guidance, thin leads are passed through a needle into the epidural space near the spinal cord and connected to an external battery you wear for about one to two weeks. There is no large cut at this stage.

If the trial gives you enough relief — usually at least half your pain reduced, with better function — you go on to the full implant. The leads are secured and tunnelled under the skin to a battery (pulse generator) placed in a small pocket, commonly in the back, buttock or tummy. This needs small incisions and may be done under local anaesthetic with sedation or under general anaesthetic. Each stage usually takes around one to two hours, and many people go home the same day or after a short stay.

Afterwards, the device is programmed and adjusted to find the settings that best ease your pain. You learn to control it with a handheld remote.

Is this operation right for me?

A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.

Before you decide

Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.

Anaesthetic choices

The safest option depends on the operation, your health, the facility and your surgeon/anaesthetist. Ask what is planned and why.

This is surgery near the spinal cord, so although serious complications are uncommon, they matter. The most common problems are lead movement and the need for further operations, and infection is the complication most likely to mean removing the device. Benefit can also fade over time. Ask your team how many implants they do, their own infection and reoperation rates, what happens if the trial fails or the device stops helping, and how future MRI scans will be handled.

Published figures to discuss

Complication rates vary between studies, devices and centres, and benefit can lessen over time, so figures should be read as broad guides rather than promises. Reported complications are dominated by lead movement and the need for further surgery, with infection being the problem most likely to require removing the device. Patient selection and a successful trial strongly influence outcomes.

These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.

Recovery — what to expect, and when

Recovery happens in two parts — after the trial and after the full implant. The implant needs several weeks of careful, restricted movement so the leads can settle and are less likely to move, while the small wounds heal.

• Soreness, bruising and tightness around the wounds and battery pocket
• Needing to limit bending, twisting and lifting in the early weeks
• Some trial-and-error while the stimulation settings are adjusted
• Gradual return of activity rather than an instant change
• A small lump where the battery sits under the skin

Aftercare

• Keep the wounds clean and dry and follow advice on dressings and showering.
• Avoid bending, twisting, heavy lifting and reaching overhead in the early weeks to protect the leads.
• Use your handheld controller as taught, and attend programming appointments to fine-tune the settings.
• Take any prescribed antibiotics or pain relief as directed.
• Watch the wounds for signs of infection and report them early.
• Carry your device identification card and tell other clinicians you have an implant before any scan or surgery.
• Keep up gentle activity, physiotherapy and self-management as advised.
• Go to follow-up appointments so healing, settings and benefit can be checked.

• Specialist team (multidisciplinary) assessment completed, including psychological input
• A clear understanding that the trial comes first
• Help arranged at home for the restricted early weeks
• A pain and activity diary to judge the trial and results
• Your device identification card and MRI information
• The clinic's contact number and out-of-hours route
• An agreed plan for what happens if the trial fails or benefit fades

Scars and how they heal

The trial uses needles, so it usually leaves only tiny puncture marks. The full implant needs small incisions — one over the spine where the leads are anchored and one over the battery pocket (often in the back, buttock or tummy) — which leave scars a few centimetres long. The battery sits under the skin and is usually felt as a small bump, which may be visible in slim people. Scars fade over months but do not disappear, and there is a small chance of the skin over the device thinning or, rarely, breaking down.

⚠ Get urgent help if…

• Spreading redness, heat, swelling, discharge or opening of a wound, or a fever — possible infection
• Severe back pain, new leg weakness, numbness, or loss of bladder or bowel control — seek emergency help
• A severe headache after the procedure, especially when sitting or standing up
• The skin over the battery or leads becoming very thin, red or breaking down
• Sudden loss of stimulation with a marked return of pain
• Stimulation that suddenly becomes painful, jolting or uncontrollable

Who to contact: your surgeon or clinic first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.

General guidance — it doesn't replace the specific advice your surgeon gives you.

Results & realistic expectations

A 'good' result is a meaningful, lasting reduction in pain — often described as at least half the pain relieved — together with better function, sleep and quality of life, and sometimes less need for strong painkillers. Around the trial stage, the team uses your response to decide whether a permanent implant is worthwhile; roughly half to two-thirds of carefully selected people get enough relief to proceed, though figures vary.

A stimulator does not cure the underlying condition or remove all pain, and benefit can lessen over the years. Success depends heavily on careful selection, a positive trial, good programming and realistic expectations. It is one part of a wider pain plan, not a stand-alone fix.

Many people keep useful benefit for years, but relief can fade over time and settings often need adjusting. Non-rechargeable batteries eventually run out and need replacing with a small operation; rechargeable ones last longer but must be charged through the skin and still have a finite life. Leads can move or fail over time, and some people eventually need revision surgery or, occasionally, removal of the system.

Combining with other procedures

A spinal cord stimulator is used alongside physiotherapy, self-management, a pain-management programme and medicines as needed. It is not usually combined with other implants in the same area, and your team will plan how it fits with any future spinal surgery or scans.

Follow-up & long-term care

After the implant you are seen for wound checks and for programming sessions to fine-tune the stimulation, then reviewed regularly to check benefit, settings and battery life. You should have a clear route back to the team if the device stops helping, the wound looks infected, or you develop new neurological symptoms.

• Regular programming and review appointments to keep settings effective
• Recharging the battery through the skin if you have a rechargeable system
• Eventual battery replacement (a small operation) for non-rechargeable systems
• Telling any clinician about the implant before scans or other surgery
• Possible revision surgery if leads move, break or stop working
• Ongoing physiotherapy and self-management alongside the device

Revision and secondary surgery reality

• Further surgery is relatively common over the life of the device, most often for lead movement, breakage or battery replacement.
• Non-rechargeable batteries will need replacing with a small operation when they run out.
• If infection reaches the device, it usually has to be removed and re-implanted later once the infection has cleared.
• Some people lose enough benefit over time that the system is eventually removed.

Ask your surgeon for their own revision rate, what counts as a revision, and what is included in the written aftercare policy.

What good aftercare looks like

• A named contact and clear urgent route for infection or new neurological symptoms.
• Programming and review appointments to keep the stimulation effective.
• A plan for battery monitoring, recharging or replacement.
• Clear MRI and 'tell other clinicians' instructions, with a device identification card.
• Joined-up care with physiotherapy, psychology and the wider pain team, and an honest plan if benefit fades.

What affects the cost

Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:

• The specialist team assessment, including psychological assessment, before treatment
• Two procedures — the trial and, if successful, the full implant
• The surgeon's and anaesthetist's fees and theatre or procedure-room costs
• The device itself, including leads and battery, and whether it is rechargeable
• Programming and follow-up appointments to set and adjust the device
• Possible future costs for battery replacement or revision surgery
• Management of any complication, which can add significantly to cost

• Whether the specialist team assessment is included
• The cost of the trial and, separately, the full implant
• Surgeon, anaesthetist and facility fees for each stage
• The device, leads and battery, and the type of battery
• Programming and follow-up appointments
• What happens, and what it costs, if the trial fails and no implant is done
• The policy and cost for complications, revision surgery or battery replacement

On the NHS? Spinal cord stimulation is available on the NHS for selected patients meeting NICE criteria after specialist team assessment and a successful trial; private access may be used for speed or choice.

You're entitled to your total cost in writing — including aftercare and any revision — before you decide.

Consent traps and marketing red flags

These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.

Choosing a surgeon safely

• Check your surgeon is on the GMC Specialist Register for this area.
• Make sure they practise at a CQC-registered location, and look for membership of bodies like BAAPS or BAPRAS.
• You're entitled to a two-stage consent process with time to reflect (a cooling-off period). The surgeon who will operate must consent you — not a salesperson.
• Be wary of pressure: time-limited offers, discounts or deposits taken before you've had time to think are red flags, not bargains.
• You're entitled to your total cost in writing — including aftercare and any revision — before you decide.
