Can you push a slipped disc back into place?

Someone felt the slipped disc in my back and pushed it back in! …..REALLY?! What does the science say?

Unfortunately, this is something that I hear from patients all the time at Hawkes Physiotherapy, but it is just so wrong. In fact, there has even been research done by Demoulin et al (2018), where they looked into the beliefs of patients about spinal manipulations and cracking, amazingly they found that 33% of people answered yes to the question, ” Can you push a slipped disc back into place or does cracking your back change joint alignment?”

The myths of Physiotherapy….

Now I don’t know where to start with this because it’s just not possible to push a disc back in based on normal human anatomy. The thing that perpetuates the myth is that whatever technique is used it can bring about symptom improvement, which I don’t dispute at all. However, the statement about what it has done and why it has done it is so far off base that it’s crazy!

So answering the first question: Can you feel a disc in the lower back?

I’ll let the pictures illustrate the answer below:



The first problem is the depth. Look below at how deep into the body that disc is! It is not far off halfway to your middle. So even if all the stuff in the way was soft and gooey and you could simply push your finger into where the disc is, your finger would be too short!

The next problem is that the ‘stuff’ above it isn’t soft and gooey, it’s tough and hard! You have skin, fascia, muscle, ligament and bone to get through.

Fascia, for example, is made of collagen, which is extremely tough and this makes fascia very tough. This makes it nearly impossible to move, which is supported by Chaudhry et al (2008).




If you look below, where the fascia, muscle and ligaments are removed the amount of disc that you can see is very small so even if the above issues weren’t there then you would have to be very accurate to feel it.




So the fact that you can’t feel it means that you can’t tell if they are ‘out’, calcified or anything else and for the same reason, you can’t just push discs back into place.

Even if you could push on them, the problem then would be that they are very hard structures that don’t move easily. This is highlighted by Adams et al (2000) who found that 2 degrees of Lumbar extension (arching the lower back) increased the maximum compressive stress within the posterior annulus of the disc by an average of 16%, compared with a neutral standing posture. It was found that disc force is 404 Newtons on L5 in standing according to Shirazi-Adl et al (2005), which is 41kg.



So arching your back to just 2 degrees would place 48kg of force on the L5 disc. Now I’m pretty sure that you would struggle to place this force onto the disc by hand even if you had very long fingers that could pass through skin, fascia, muscle, ligament and bone! Above is a diagram showing disc pressure in kilograms on the discs, as you can see they are huge!



So, in summary, you can’t touch a disc, tell what state it is in from touch or push a slipped disc back into place by hand. However, we can assess you with a thorough subjective and objective physiotherapy examination, which is exactly what we do at both of our clinics in Stoke-on-Trent.

Online Physiotherapy

Put simply this is Physio done via either telephone or video over the internet. Skype and facetime are examples of this.

Contrary to popular belief online physiotherapy can be very effective and it can help the same injuries that face to face physio can help. I have helped many people with injuries such as disc prolapses, tennis elbow, neck pain and much more).
