What happens when my back cracks?


Back cracking also known as joint mobilisation, joint manipulation and joint adjustment is a type of technique that a lot of osteopaths use as part of their treatments. Some osteopaths use them very frequently and others not at all. As an osteopath myself, I do use joint manipulation as part of my treatments but I only perform them on people who one – would actually benefit from it (as not everybody needs manipulation) and two – only with other techniques to maximise the effectiveness of the treatment. The General Osteopathic Council now advises that manipulation is explained to all patients before it is performed and consent to perform the manipulation is obtained. In this blog, I will explain what manipulation is, how and why it is done and briefly explore the other possible causes of back cracking.

Facet joints

In order to understand how a manipulation works, a basic understanding of spinal anatomy is required. The spine is made up of blocks called vertebrae which are stacked on top of each other like a tall tower. Each vertebrae is separated from each other by a spinal disc that sits in between each one. Each vertebrae has two facet joints attached to it, one on the left and one on the right. The facet joints of one vertebrae connect with the facet joints on the vertebrae above and with the facet joints on the vertebrae below so that each vertebrae are in contact with each other. These facet joints are strengthened by ligaments and muscles and are surrounded by a little joint capsule. Fluid known as synovial fluid sits within the joint capsule and its role is to lubricate the joint so that the facet joints can move smoothly without getting stuck on each other. During an osteopathic manipulation, it is the movement of these facet joints that causes the audible ‘pop’ or ‘crack’ you can hear.

During the manipulation

During the manipulation, the osteopath will focus a little pressure onto the appropriate facet joint. The manipulation may involve a little twist or thrust movement. During the thrust, the air pressure in the facet joint is suddenly altered. When this happens, gas escapes from the joint and produces a ‘pop’ or ‘crack’ sound. This shouldn’t be painful. When air pressure has changed in the joint, it takes around 20 minutes for the joint to regain normal air pressure again. During this period you will not be able to manipulate the joint again. (That’s why when you crack your knuckles, you have to wait for a little bit before you can do it again).

Why manipulate?

Spinal manipulation in the back and neck has been shown to help improve the symptoms of some people suffering with back and neck pain. The aim of a manipulation is to restore joint function in the spine, increase the joint movement and reduce pain. Whilst back manipulation has been shown to achieve these positive effects, some people can react adversely to manipulations. There are over 100 types of joint manipulation techniques and if the wrong technique is used, there is a risk of potentially harming the spine. Therefore it is recommended that you do not try to manipulate your own back or neck and only have a trained health care professional such as an osteopath, physiotherapist or chiropractor perform the manipulation.

Other causes of cracking spinal joints

It is possible to experience an involuntary crack from time to time. If the cause is not attributed to a direct manipulation, other likely causes are:

  • Ligament or tendon snapping – this is completely normal and involves surrounding ligaments and tendons flicking over each other or other bits of bone as they move. (This is also very common in the hips and knees).

  • Bone grinding – as we get older, the spine may start showing signs of wear and tear. This is a normal part of ageing. As the cartilage in the spine starts to break down, it provides less protection and cushioning for the bones of the spine and as a result they can start rubbing on each other which can create a ‘crack’, ‘pop’ or ‘grinding’ sound.

Is manipulation safe?

Whilst the long term benefits of back cracking is not known, it has shown to provide short term temporary relief for certain types of back and neck pain. That said, not all types of back and neck pain are suitable for manipulation. Other factors such as age, certain conditions or lifestyle habits may also mean that manipulation isn’t appropriate. Further research is required to fully understand the long term implications. This is also another reason why having your back or neck cracked should only be done when necessary. Other osteopathic techniques should be used alongside manipulation and advice on certain exercises and stretches should also be used as part of the treatment plan.

It’s important to stress that back and neck manipulation is not a cure. The aim is to provide TEMPORARY relief to symptoms whilst using other techniques and exercises to produce a more long term solution for your symptoms. It’s very easy to get caught in the ‘crack it to feel better’ cycle and I’ve encountered patients who crack their own necks and backs sometimes up to 30 times a day! For those who are addicted to self-cracking, my advice is to stop – even if you feel like you need it. If the body gets used to being manipulated too frequently, it is possible to over stretch the surrounding ligaments and muscles which can lead to long term pain and instability in the spine. Osteopathy can help you discover why you feel the need to consistently crack your own back and neck and provide you with a safer means to reduce your symptoms. I hope this information has been useful. If you are concerned about your own back or neck, or you have any questions, feel free to get in touch!
