Researchers from the University of Sydney want to compare two types of spinal surgery; one that includes bone and ligament removal and another that does not (placebo).

Study Purpose/Description

Lumbar stenosis occurs when the space around the spinal canal in the lower back becomes narrow, pressing on the spinal nerves. Surgery to treat lumbar stenosis involves a general anaesthetic and a small incision into the skin and muscles of the spine, to remove small portions of bone and ligament that are pressing on the nerves. This type of surgery is called ‘decompression’.

Currently there is no definite evidence that removing bone and ligament is required to improve pain and walking after surgery. While some patients who have this decompression surgery have relief from their symptoms, others do not, and we do not understand why.

To see how important the removal of bone and ligament is, the SUcceSS Team are performing a study that compares two types of spinal surgery; one that includes bone and ligament removal and another that does not (placebo). The results will allow the research team to determine if the removal of bone and ligament during surgery (decompression surgery) is effective for the treatment of lumbar stenosis or not.

What’s involved?

If you are eligible to join the study, you will have a 50% chance of receiving spinal decompression involving bone and ligament removal (decompression surgery) and a 50% chance of receiving spinal surgery without bone removal (placebo surgery).

After the surgery, the SUcceSS Team will then contact you to monitor your symptoms every 3 months over 2 years. Most of this contact will be conducted via telephone appointments.

Recruitment criteria

You may be eligible to participate in this study if:

  • You are older than 40 years of age
  • You have neurogenic claudication (e.g., pain, numbness, and/or fatigue in or below the buttocks that is worse with walking and better when you sit or lean forward)
  • Your symptoms have been present for at least 3 months
  • Your symptoms have not improved with non-surgical management.
  • You are eligible and medically fit to receive decompression surgery (single or dual level).

The Join Us Register Acknowledges the Traditional Owners of the lands across Australia as the continuing custodians of Country and acknowledge the many Aboriginal and Torres Strait Islander people of this land. We pay our respect to First Nations peoples and Elders, past and present.

We acknowledge and celebrate the knowledge and the strengths of Aboriginal and Torres Strait Islander peoples and communities and recognise their continuing connection to land and waters.

We thank the many Aboriginal and Torres Strait Islander communities, and the many individuals, organisations that have supported and guided us through our journey.

There is a huge opportunity to partner more with Aboriginal and Torres Strait Islander communities to build on existing community strengths and resilience, often in the face of ongoing inequities. Through Join Us, we will work together in the spirit of reciprocity to address ongoing impacts of colonisation so that we can all realise optimal health and wellbeing.
