- Spine pain can come from the disc, the space around the nerves, or the small joints at the back.
- Each has its own route: intradiscal, epidural or facet joint, placed under live X-ray guidance.
- Your imaging decides which route fits, and the research is promising and growing.
“Stem cells for your back” sounds like one thing. It isn’t. Your spine is more like an apartment building than a single room, and pain can live on different floors: inside a disc, in the hallway where the nerves run, or in the small hinges at the back.
Where the cells go should depend on where your pain comes from. Here is what the three spinal routes are, how they are done, and what you can reasonably expect from each.
Which part of your spine is actually hurting?
Three structures cause a lot of chronic back and neck pain:
- The discs, the cushions between vertebrae. When they wear or tear, they can hurt on their own and irritate nearby nerves.
- The epidural space, the channel around the nerve roots. Inflammation here is behind much of the burning, shooting pain of sciatica.
- The facet joints, pairs of small joints at the back of each level. They can develop arthritis, just like a knee.
Many people have more than one of these going on. That is why a specialist reads your MRI before deciding anything.
What is an intradiscal application?
The needle goes into the disc itself, aiming at the inner core. It is the most direct route for pain that comes from a worn or damaged disc, and it is also the most technical, because the target is small and close to nerves.
The aim is for the cells’ signals to act where the degeneration is happening, calming inflammation and supporting the tissue that is left.
What about epidural and facet applications?
An epidural application places the cells in the space around the nerve roots rather than inside the disc. It can reach inflammation along several levels, and it avoids puncturing the disc.
A facet joint application treats the small joints at the back, much as a knee or hip application treats a larger joint. It is a natural fit when imaging and symptoms point to facet arthritis.
Why does the guidance matter so much?
Think of parallel parking at night with a camera versus without one. With spinal applications, the camera is fluoroscopy, a live X-ray that shows the needle moving in real time, so the cells are placed exactly where the plan says.
That is also why the setting matters. A spinal application belongs in an operating room with monitoring, under sedation, done by physicians who place needles in the spine as part of their daily work.
Who could benefit?
People who usually get a closer look include those with a herniated or bulging disc that hasn’t settled with physical therapy, sciatica linked to a disc, degenerative disc disease, or facet arthritis, especially when epidural or facet injections helped for a while and then wore off sooner each time.
Your imaging and your history decide the rest. A specialist reviews your case first, so your plan is designed for you, before you travel.
What can you expect afterwards?
You rest at the hotel, one elevator away, with your coordinator checking on you. Improvement builds gradually and is usually expected at 4–6 months, and some people keep improving at eight months.
Every body responds at its own pace, and your follow-up tracks it with you. This path keeps every other option open.
- Get a recent MRI: X-rays alone rarely show disc problems.
- Ask which structure the specialist thinks is causing your pain, and which route that means.
- Send your MRI on WhatsApp for a free evaluation, with your plan and price in writing and no commitment.
The research is growing across the three routes. For intradiscal injections, a 2024 systematic review of randomized and observational studies rated the evidence for mesenchymal stem cells and platelet-rich plasma as fair (Level III), suggesting they may help discogenic low back pain. For epidural biologics, a 2026 review found nine randomized trials of biologic treatments, and facet and epidural use of umbilical cord cells has been described in case reports. Promising, and growing.

Questions
Which route is right for me?
It depends on where your pain comes from. A specialist reviews your MRI and symptoms and explains which structures to treat, sometimes more than one.
Is the procedure painful?
It is done under sedation. Afterwards you rest at the hotel, one elevator away, with your coordinator checking on you.
How long do I stay in Medellín?
The treatment itself is one day. The doctors recommend staying at least two days after the application to rest.
Is it approved by the FDA?
Stem cell therapy is not approved by the FDA, but in Colombia it is legal.
What if I don’t have a recent MRI?
Your coordinator can arrange one in Medellín, starting from $200 per body area, with transfers included.
