Your care team will support you throughout your recovery, helping you manage symptoms, regain movement and function, and return to your usual activities safely and confidently at a pace that is right for you.
What is spinal instability?
Spinal instability occurs when the spine can no longer maintain its normal alignment during everyday activities. This abnormal movement may cause back or neck pain, nerve compression, and difficulty with mobility and function.
What causes spinal instability?
You may have sudden, severe pain in your neck or back and find it difficult to move comfortably. The muscles around the injured area may also feel tight or go into spasm.
If your spinal cord or nerves are affected, you may notice tingling, numbness or weakness in your arms or legs. This can also make walking or moving your arms and hands more difficult.
. Get emergency help if you develop new weakness or loss of feeling, particularly if you also notice changes in your bladder or bowel control.
How is spinal instability?
Your consultant will ask about your symptoms and medical history and carefully examine your neck or back. They will also assess your strength, sensation and reflexes to check whether any nerves or the spinal cord are affected.
Imaging scans are usually needed to confirm the diagnosis and understand the cause of the instability. X-rays, CT scans and MRI scans can help identify abnormal movement between the vertebrae, spinal alignment problems, fractures, ligament injuries, or pressure on the nerves and spinal cord.
A CT (computed tomography) scan provides detailed images of the bones and can help identify fractures, displacement, dislocations or subluxations. An MRI (magnetic resonance imaging) scan allows your consultant to assess the spinal cord, nerves, discs and supporting ligaments in greater detail and determine whether these structures have been injured.
For some patients, specialised standing or flexion-extension X-rays may also be used to assess how the spine moves and whether instability is present during movement.
How is spinal instability treated?
Treatment aims to carefully move the bones back into their normal position and make sure your spine remains stable. Your consultant will look at how far the bones have moved and whether your spinal cord or nerves have been affected before recommending the best approach for you.
The medical term for moving the bones back into place is reduction. This may be done using controlled traction, which applies a gentle pulling force, or as part of an operation. Your specialist will explain what they recommend and why, and answer any questions you have.

Treatment routes for Spinal instability
Your treatment will depend on where the injury is and how far the bones have moved. Some partial dislocations can heal without an operation, while a full dislocation or an unstable injury is more likely to need surgery.
Some patients can be managed without surgery using a combination of activity modification, physiotherapy and pain management.
Working with Spine professionals and teams
