Lumbar Nucleoplasty

(This is the section that explains the detail of the operation or procedure above and should be read in conjunction with the section Your Back Operation).

A lumbar Nucleoplasty is performed for pain that is caused by damaged intervertebral discs. The aim of the procedure is to reduce the pressure on the small nerves that are found in the annulus fibrosus. This is done by shrinking the nucleus pulposus (see the section Anatomy of the Spine). The modality used for this is similar to radiofrequency rhizotomy, but a device is used which utilises coblation technology to dissolve tissue without damage to nearby normal structures.

The reason why your specialist performs this procedure and not a more invasive procedure is because he or she is trying to be as conservative as possible in treating your condition. The aim is to treat your symptoms without resorting to a more invasive operation.

When undergoing this procedure, you will be lying on your stomach on bolsters or pillows. Your specialist will use an X-ray machine to guide the needle that is used to do the procedure with. A patented plasma device is then inserted through the needle into the disc, whereby excess tissue is removed. Removing some of the tissue from the centre of the disc causes a reduction in intra-discal pressure, which in turn eases symptoms.

These illustrations demonstrate a Nucleoplasty. The needle is inserted into the disc under fluoroscopic (X-ray) guidance and close to the area where the disc is bulging. Coblation therapy enables tissue to be removed quickly and efficiently without damaging nearby normal structures. The picture second from the top demonstrates how the tissue is actually “dissolved”. 


Ward care

You may sometimes have a bit of discomfort directly after the procedure, but this will clear up very soon. You will be allowed to move around freely following your procedure.


This procedure is usually performed as a day procedure, although in some cases patients might need to stay in hospital overnight.


It is incredibly important to get a lot of rest and exercise following your procedure. It is frequently useful to supplement your treatment with physiotherapy and local treatment such as massage therapy and chiropractic treatment.


Routinely you will receive a date for your follow-up appointment with your specialist. This may vary from anything between two and six weeks, but you will be seen earlier if there are any complications. It is important to realise that you will have to protect your back for the rest of your life and apply good back habits (see the section Caring for your Spine). It is also important to appreciate that the efficacy and longevity of this treatment is still under investigation.
