Lumbar Decompression Surgery
Lumbar decompression surgery relieves pressure on the nerves in the lower spine by removing the disc, bone or thickened tissue that is pinching them. It is used for leg pain, numbness or weakness caused by a slipped disc or spinal stenosis when non-surgical treatment has not worked, and it aims to ease leg symptoms and improve walking.

Overview
Lumbar decompression is a group of operations that free the spinal nerves where they are compressed in the lower back. A microdiscectomy removes the fragment of a herniated (slipped) disc pressing on a nerve root, while a laminectomy or laminotomy removes bone and thickened ligament to widen a narrowed spinal canal in spinal stenosis. Surgery is often performed through a small incision using microsurgical or minimally invasive techniques, and is typically aimed at relieving leg-dominant symptoms — pain, pins and needles or weakness — rather than back pain alone. Where the spine is unstable, decompression may be combined with a fusion, which the surgeon discusses separately.
Decompression is usually considered only after a fair trial of non-surgical care, or sooner when there is significant or progressive weakness. For patients travelling from abroad, a dedicated coordinator arranges appointments, a clear treatment plan and a transparent cost estimate before travel, including the expected length of stay and rehabilitation, and our spine surgeons can review your MRI or CT imaging remotely first so you have an expert opinion before deciding on surgery or travel.
Who is a candidate?
- People with leg pain, numbness or weakness (sciatica) from a slipped disc pressing on a nerve
- Patients with spinal stenosis whose legs ache or tire and whose walking distance is limited
- Those whose symptoms persist despite physiotherapy, medication and, where used, injections
- People with weakness or symptoms that are getting worse, who may need earlier surgery
- Patients whose MRI or CT findings clearly match their symptoms
- Anyone with signs of severe nerve compression (such as loss of bladder or bowel control), which needs urgent assessment
What happens
- 1
Assessment and planning
Your symptoms, examination and MRI or CT scan are reviewed to confirm which nerves are compressed and which type of decompression is appropriate. Imaging and reports can be reviewed remotely before travel.
- 2
Preparation
Your team optimizes your health for surgery, plans the anesthetic and explains the operation and recovery, including which activities to limit at first and the rehabilitation that follows.
- 3
The operation
Under general anesthesia and usually through a small incision, the surgeon removes the disc fragment, bone or thickened ligament that is compressing the nerves, often using a microscope or minimally invasive technique to protect healthy tissue.
- 4
Early recovery
Many patients are encouraged to stand and walk on the same or the next day, and leg symptoms often ease quickly. You are guided on posture, sitting and how to move safely in the early days.
- 5
Rehabilitation
A graded program of walking and physiotherapy over several weeks rebuilds strength and confidence, with heavy lifting and bending limited at first. International patients receive a home plan and can be supported remotely after returning home.
Benefits
- Relieves leg pain, numbness and pins-and-needles caused by nerve compression
- Often improves walking distance and standing tolerance in spinal stenosis
- Can halt or improve nerve-related leg weakness when treated in time
- Minimally invasive and microsurgical techniques mean smaller incisions and a quicker recovery
- Many patients reduce their reliance on pain medication
- Restores the ability to return to everyday activities and work
Risks & considerations
- Infection, bleeding and blood clots, as with any surgery
- A tear of the dura (the lining around the nerves), causing a fluid leak that may need extra care
- Injury to a nerve, which can rarely cause new or persistent numbness or weakness
- Incomplete relief, or back pain that improves less than the leg symptoms
- Recurrence of a disc herniation or regrowth of narrowing, sometimes needing further surgery
- In some cases the need for spinal fusion if instability is present
Where it is performed

Lumbar Decompression Surgery — frequently asked questions
Most slipped discs and many cases of stenosis improve with time, physiotherapy, medication and sometimes injections, and surgery is usually considered only when these have not helped. Surgery may be advised sooner if there is significant or worsening weakness. Our spine surgeons review your MRI and symptoms and give an honest opinion on whether decompression is needed.
Decompression is generally most effective for leg-dominant symptoms — pain, numbness or weakness from a pinched nerve — and many patients gain marked relief. Back pain may improve less, because it can have other causes. Your surgeon explains realistically what your symptoms are likely to respond to.
Many patients walk the same or next day and return gradually to activity over six to twelve weeks, avoiding heavy lifting and bending at first. Return to work depends on whether your job is sedentary or physical; your team gives you a personalized timeline and rehabilitation plan.
Lumbar decompression usually means about one to three days in hospital plus further recovery locally, and your coordinator confirms the expected nights in hospital and in the city. We provide a transparent, itemized cost estimate after reviewing your case — covering assessment, surgery, hospital stay and follow-up — rather than quoting fixed prices online, because each plan is individual.
Yes. Send your lumbar MRI or CT scan and reports and our spine surgeons give an independent opinion remotely on whether decompression is appropriate, which type, and whether a fusion might be needed, so you can decide before travelling.
No. Decompression relieves pressure on the nerves, whereas fusion stabilizes the spine by joining vertebrae together. They are sometimes combined when the spine is unstable, but many decompressions are done on their own. Your surgeon explains which approach your condition needs and why.
