Lumbar decompression surgery
Lumbar decompression surgery relieves pressure on nerves in the lower spine. It may help improve leg pain, numbness or weakness when symptoms have not settled with other suitable treatments.
Lumbar decompression surgery overview
Compressed nerves can be caused by spinal stenosis, a slipped disc, sciatica, a spinal fracture or, less commonly, another condition within the spine. Cauda equina syndrome can also require urgent decompression when the nerves at the base of the spine become suddenly compressed. Your consultant will explain whether surgery is suitable after reviewing your symptoms, examination, scans and response to non-surgical treatment.
How is surgery carried out?
The procedure is carried out in hospital under a general anaesthetic. The surgeon reaches the spine through one incision or several smaller incisions in the back. Depending on the cause of pressure, the operation may include:
- Laminectomy: removing a small section of bone from a vertebra to create more space.
- Discectomy: removing part of a damaged disc that is pressing on a nerve.
- Spinal fusion: stabilising part of the spine when this is needed.
The operation commonly takes around two to four hours but may take longer. Many people leave hospital after around two to five days, depending on the procedure and recovery.
Are there any risks?
Serious complications are uncommon, but every operation carries risks. Your consultant will explain these in full. Possible complications include:
- infection, bleeding or a reaction to the anaesthetic
- a leak of spinal fluid, which may need further treatment
- damage to a spinal nerve and, very rarely, paralysis
- persistent or recurrent pain
- instability or movement between vertebrae that may require another operation

Recovery from lumbar decompression surgery
Walking and going home
Many people begin walking within a day. Your care team will tell you how to move safely, care for the wound and recognise symptoms that need attention.
Returning to routine
Some people can return to work after around four to six weeks, depending on the type of work and their recovery. Gradually increase walking and other activities, following the advice you have been given.
Usual activities
It can take up to twelve weeks to resume all usual activities, and some people take longer. Your consultant and physiotherapist will guide your return to driving, lifting and sport.
Working with Spine professionals and teams
Our spine specialists support professional athletes, sports teams, active individuals and people whose work places high demands on their spines. Working closely with radiologists, physiotherapists and the wider multidisciplinary team, they provide coordinated care from diagnosis through to rehabilitation, helping each person return safely to sport, work or everyday activities.
The same specialist expertise and collaborative approach are available to every patient, whatever your activity level or recovery goals.

How to pay
We offer flexible options depending on how you choose to access care at Fortius. Whichever option you choose, we’ll help make the process clear and straightforward from the start.

Private medical insurance
If your care is covered by private medical insurance, we’ll usually invoice your insurer directly. Please check your policy in advance and request an authorisation code if your insurer requires one. You’ll be responsible for paying any policy excess or costs that aren’t covered by your insurance.

Paying for yourself
You don’t need private medical insurance to access care at Fortius. If you’re paying for your own treatment, our team will explain the costs clearly and provide a personalised quote before you decide whether to go ahead.

It may be used for spinal stenosis, a slipped disc, sciatica, a spinal fracture or another condition that compresses nerves in the lower back. Your scans and symptoms will determine whether it is suitable.
Some people return after four to six weeks, but manual work may require longer. Your surgeon will advise you based on the operation and your progress.
Return gradually and only when your specialist advises you to. The timing depends on the operation, your recovery and the type of sport.
