Percudyn Facet Augmentation



Percudyn is a facet augmentation system aimed at treating low back pain. A screw is inserted percutaneously into the pedicle of the vertebra below the effected disc. This is connected to a ‘shock absorber’, which limits the pressure on the facet joint and part of the disc. This can reduce low back pain.
The advantage of this device is that it does not cause any significant damage to the spinal structures and allows the spine to continue moving. It is a true minimal invasive device.


Low back pain due to degenerative disc disease, which has not responded to non-surgical treatment. There are specific criteria for the use of this device, which should be discussed with the surgeon performing this procedure.


Infection, bleeding, CSF leak, neurological damage including paralysis and incontinence (very small), no improvement of symptoms and metal / hardware failure or incorrect placement of the device.

Hospital stay

24 after operation in majority of cases but can be done as day case.


Usually general anaesthesia but can be done under sedation.


The back might feel sore for a short time. Recovery is usually quick and patients can return to work within 1-2 weeks.

Commonly asked questions

What happens if my pain does not improve after surgery?
The advantage of this device is that it does not cause any significant damage to the spine. Therefore it can be removed or left in. If a lumbar fusion is considered this can be done without any problems but the device would need to be removed at the same time.
Why might the pain not improve after surgery?
Low back pain has usually several causes and it can be difficult to establish where exactly the pain comes from (see low back pain’ ). Percudyn only treats some aspects of the pain.
