Nucleoplasty

What is Nucleoplasty?

Nucleoplasty is a minimally invasive procedure designed to treat lower back pain caused by a contained herniated disc or degenerative disc disease. This technique uses a specialised radiofrequency device to decompress the affected intervertebral disc by removing small amounts of disc material, thereby reducing pressure on nearby nerves, and alleviating pain.

How does Nucleoplasty work?

The treatment works by using coblation technology, which is a form of controlled radiofrequency energy, to dissolve targeted disc tissue with minimal heat. This subsequently preserves the surrounding structures. The procedure is typically performed under local anaesthesia with light sedation, and involves the following steps:

Imaging guidance and preparation – the patient lies comfortably on the procedure table while imaging tools such as fluoroscopy guide the precise insertion of a thin needle into the affected disc space.
Disc decompression – a specialised probe is introduced through the needle and into the disc. Using radiofrequency energy, the probe ablates tiny amounts of nucleus pulposus (the gel-like material at the centre of the disc), thereby creating small channels that reduce internal disc pressure.
Nerve pressure relief – as the disc decompresses, pressure on nearby spinal nerves is relieved. This often results in significant reduction in lower back pain or leg pain (link to sciatica page) associated with the compressed nerve root.

As daunting as it sounds, the entire procedure usually takes 30 – 60 minutes, and is performed on an outpatient basis, allowing patients to return home the same day.

What are the benefits of Nucleoplasty?

Nucleoplasty offers a compelling solution for individuals seeking lasting relief from disc-related back or leg pain without undergoing open surgery. This minimally invasive treatment provides both immediate, and long-term benefits, helping patients return to their normal routines with improved function and comfort.

Some of the key benefits include:

BENEFITS	HOW IT HELPS
Delays or avoids the need for surgery	For many patients, nucleoplasty can provide sufficient symptom relief to delay or completely avoid spinal surgery. It serves as a valuable intermediate option when conservative treatments have failed but surgery is not yet warranted.
Minimally invasive with no incisions	Nucleoplasty is performed through a small needle puncture rather than a surgical incision. This significantly reduces trauma to surrounding muscles and tissues, minimises blood loss, and eliminates the need for stitches or general anaesthesia.
Lower risk of complications	Due to the fact that nucleoplasty uses controlled radiofrequency energy, and is performed under image guidance, the risk of complications such as infection or nerve damage is significantly lower than with more invasive procedures.
Performed as a day procedure	Nucleoplasty is done on an outpatient basis, meaning you can return home the same day, without the need for hospitalisation or overnight stays.
Short recovery time	Patients often resume light activities within a few days, compared to weeks or months of recovery associated with traditional spine surgery. This makes nucleoplasty an ideal option for those looking to minimise downtime.
Targeted pain relief	By precisely removing a small portion of the nucleus pulposus, nucleoplasty directly reduces intradiscal pressure, and relieves compression on nearby spinal nerves, leading to effective, and localised relief from back pain or sciatica.

Are there any risks or side effects?

Fortunately, the treatment is considered safe, and well-tolerated, particularly when performed by an experienced specialist using image-guided precision. However, like all medical procedures, there are some potential risks:

Common and usually mild side effects

Swelling or bruising – due to needle insertion, which usually resolves on its own.
Temporary flare-up of symptoms – symptoms may briefly worsen before improving.
Temporary localised pain – mild soreness or stiffness around the puncture site, lasting a few days.

Rare but possible complications

Bleeding or haematoma – especially in patients on blood thinners.

Incomplete pain relief – while many patients report significant improvement, some may require additional therapy or further evaluation.
Infection – extremely rare, but may require antibiotics or further treatment.
Nerve irritation or injury – minimal risk when performed with fluoroscopic guidance.

Who is a Nucleoplasty recommended for?

Individuals who have been experiencing persistent lower back or leg pain that has not responded to non-surgical treatments are typically the most ideal candidates for nucleoplasty. Additionally, these candidates often meet the following criteria:

Chronic back pain or sciatica lasting more than 6 weeks.
Degenerative disc disease causing disc bulging and pain, but with preserved disc height.
Desire to avoid open surgery, specifically patients preferring a less invasive solution with faster recovery.
Failure of conservative treatment, such as medication, physiotherapy, rest or spinal injections.
MRI-confirmed contained disc herniation, where the disc is bulging but the outer wall remains intact, with no fragment migration.

Other than that, patients with sequestered disc fragments, spinal instability or severe spinal stenosis may not be ideal candidates. Even so, a detailed assessment by our spine specialist (link to about us page), including medical history, and imaging review, will help determine if nucleoplasty is appropriate for your condition.

What conditions do Nucleoplasty treat?

Chronic back pain or sciatica lasting more than 6 weeks.
Degenerative disc disease causing disc bulging and pain, but with preserved disc height.
Desire to avoid open surgery, specifically patients preferring a less invasive solution with faster recovery.
Failure of conservative treatment, such as medication, physiotherapy, rest or spinal injections.
MRI-confirmed contained disc herniation, where the disc is bulging but the outer wall remains intact, with no fragment migration.

What to expect after a Nucleoplasty procedure?

Recovery is typically smooth, and predictable, with minimal discomfort and a swift return to daily activities. But generally, here is what you can expect:

Immediately after the procedure

You will rest in our clinic for a short observation period before being discharged the same day.
Mild soreness or a dull ache around the needle insertion site is common, and usually resolves within a few days.
You will be advised to arrange transport home, and avoid driving on the day of the procedure due to sedation effects.

First few days

Most patients can resume light activities, such as walking or desk work, within 24 – 48 hours.
Heavy lifting, bending or strenuous exercise should be avoided for 1 – 2 weeks to support disc healing.
Over-the-counter pain relief may be used as directed to manage any temporary discomfort.

Longer-term recovery

Noticeable pain relief often begins within a few days but may continue to improve over 2 – 6 weeks as nerve inflammation decreases.
Our doctor will provide a personalised rehabilitation plan, which may include physiotherapy or activity modifications.

How many sessions do I need?

Typically, nucleoplasty is performed as a single-session treatment. The goal is to relieve pressure within the affected disc, and reduce nerve compression in just one minimally invasive procedure.

However, the need for additional sessions depends on several factors, including:

The number of discs affected — if more than one spinal level is involved, separate procedures may be planned for each disc.
The severity of disc degeneration or herniation — advanced disc damage may require additional follow-up care or complementary treatments.
Your response to the initial procedure — while many patients experience significant relief from just one session, our doctor will monitor your progress, and determine whether further intervention is needed.

Summary

Nucleoplasty offers a safe, effective, and minimally invasive option for individuals with chronic discogenic lower back pain who are not ready for spinal surgery. By gently removing small portions of disc material, it reduces pressure on spinal nerves, and provides lasting relief with minimal downtime.
