Spinal Decompression Treatment vs Regenerative Injections: What Is the Difference?

What does “spinal decompression treatment” mean?

The phrase is used for two very different things, which causes a lot of confusion.

1. Non-surgical spinal decompression is a form of motorised traction. You lie on a computer-controlled table that gently pulls and relaxes the spine over repeated sessions. It is usually offered by chiropractors and physical therapy clinics for disc-related back pain and sciatica.
2. Surgical decompression is an operation that removes bone, ligament or disc material pressing on the spinal cord or nerves. Examples include laminectomy and discectomy. The NHS explains lumbar decompression surgery and who it is for.

Regenerative injections are a third, separate approach that targets the biology of a damaged disc or joint.

How do regenerative injections differ?

Regenerative injections, such as PRP therapy and stem cell therapy, do not stretch the spine or remove tissue. They deliver concentrated platelets or mesenchymal stromal cells into a painful disc, facet joint or surrounding ligaments under imaging guidance. The aim is to reduce inflammation and support the tissue’s own repair processes. This approach is studied mainly in degenerative disc disease and chronic disc-related pain, where results come from small trials (PubMed search of PRP disc trials).

Side-by-side comparison

	Non-surgical decompression (traction table)	Regenerative injections (PRP, stem cells)	Decompression surgery
What it does	Repeated mechanical traction on the spine	Biological injection into disc, joint or ligament	Removes bone or disc pressing on nerves
Typical uses	Disc-related back pain, sciatica	Chronic disc pain, facet joint pain, degenerative disc disease	Severe nerve compression, spinal stenosis, large disc herniation
Number of sessions	Usually many over several weeks	Usually one to a few treatment days	One operation
Evidence	Weak; NICE advises against traction	Limited; small and early-stage trials	Good for selected patients with nerve compression
Invasiveness	None	Guided needle injection	Surgery under anaesthetic
Main risks	Temporary soreness; not suitable for some spine conditions	Pain flare, rare infection, rare nerve injury	Infection, bleeding, nerve damage, dural tear
Approval (US/UK/AU)	Devices marketed as traction equipment	PRP widely used; cell injections not approved outside trials	Standard care

What does the evidence say about traction-based decompression?

Systematic reviews of traction for low back pain have generally not found clear benefit compared with other treatments or sham traction (PubMed search of reviews). The UK’s NICE guideline on low back pain and sciatica states: do not offer traction (NICE NG59). Some patients still report short-term relief, and the treatment is low risk for most people, but it has not been shown to change the underlying disc.

What is a non-surgical decompression session like?

You lie on your back or front on a padded table with a harness around the pelvis and chest. A computer controls cycles of pulling and relaxing, usually for 20 to 45 minutes. Courses typically involve many sessions over several weeks, often combined with heat, ice or exercise. The treatment should not be painful; increasing pain is a reason to stop and be reassessed. People with fractures, severe osteoporosis, spinal implants, tumours or spinal instability are usually not suitable.

What is a regenerative spine injection like?

A doctor uses fluoroscopy (live X-ray) or ultrasound to guide a fine needle into the target, such as a disc, facet joint or ligament. Local anaesthetic is used, and some programmes include collecting cells from fat or bone marrow on the same day. Most people go home the same day and are advised to limit heavy lifting for a period afterwards, then return to a guided exercise plan.

What does the evidence say about regenerative spine injections?

Research on PRP and mesenchymal stromal cell injections for disc pain is promising in parts but early. Most studies are small, use different products and doses, and follow patients for a limited time. Some report improved pain and function; others show results similar to comparison treatments. There is no consistent proof that injections restore disc height or reverse degeneration. These treatments should be seen as options for selected patients, not as a replacement for surgery when nerves are seriously compressed.

Who may be a candidate for regenerative spine injections?

• Chronic low back or neck pain linked on MRI to disc degeneration, a contained herniated disc or facet joint arthritis.
• Pain lasting months despite physiotherapy, exercise and standard medicines.
• No severe or progressive nerve compression.
• People who understand the evidence is limited and results vary.

Who should NOT have injections or traction, and needs a surgical opinion?

• Progressive leg weakness or foot drop.
• Loss of bladder or bowel control, or numbness around the genitals or buttocks (possible cauda equina syndrome, a medical emergency).
• Spinal fracture, tumour, infection or significant instability.
• Severe spinal stenosis causing major walking limitation.
• For injections: active infection, active cancer, bleeding disorders, pregnancy or uncontrolled diabetes.

Risks of each option

Traction can cause temporary soreness and is unsuitable for people with fractures, severe osteoporosis or spinal instability. Regenerative spine injections can cause a pain flare; infection of the disc (discitis) and nerve injury are rare but serious, which is why imaging guidance and sterile technique matter. Cells are prepared in ISO 9001:2015-certified partner laboratories. Decompression surgery carries risks including infection, bleeding, nerve damage and, in some cases, ongoing pain. The NHS covers risks of lumbar decompression surgery.

Conventional options come first

Most back pain and sciatica improves with time. The NHS guide to back pain recommends staying active, exercise and pain relief. NICE recommends exercise programmes, manual therapy alongside exercise, and psychological support for persistent pain, with spinal injections or surgery for selected cases. See lower back pain for an overview.

Next step: have your spine MRI reviewed

1. Send your spine MRI and reports on WhatsApp.
2. A Thai Medical Council-licensed doctor reviews whether your pain fits a regenerative approach or needs a surgical opinion.
3. You receive honest, written advice before any travel.
