What causes cauda equina syndrome?
The cauda equina are a group of nerves located at the bottom of the spine. If these nerves are compressed, for example when there is a slipped disc in the lower back, then the nerves can be damaged. This nerve damage can lead to serious problems.
What are the signs of cauda equina syndrome?
Key warning symptoms of cauda equina syndrome are:
- New difficulty passing urine, or new urinary retention
- New bowel incontinence or loss of sensation
- Paraesthesia (numbness) in the inner thigh, groin and buttocks
- Severe lower back pain with weakness or numbness in one or both legs
The red flag symptoms of cauda equina syndrome
Clinicians are trained to treat a particular group of symptoms as red flags — warning signs that require emergency assessment and an urgent MRI scan. The red flags for cauda equina syndrome are:
- Saddle anaesthesia — numbness or altered sensation across the inner thighs, groin, buttocks and genital area, in the region that would touch a saddle
- Bladder dysfunction — difficulty passing urine, difficulty knowing when the bladder is full, loss of the normal sensation of urinating, or retention and overflow incontinence
- Bowel dysfunction — loss of bowel control, or loss of sensation when opening the bowels
- Sexual dysfunction that has come on suddenly
- Weakness, numbness or pain affecting both legs
Where any of these are present alongside back pain, national guidance is clear that the patient should be referred for emergency assessment. A great many of the claims we see involve red flag symptoms that were described to a GP, an out-of-hours service or an emergency department, and were not acted on.
How is cauda equina syndrome diagnosed?
Cauda equina syndrome is confirmed by an urgent MRI scan. The scan shows whether the nerves at the base of the spine are being compressed and, if so, by what.
In our experience, the failure to arrange that scan promptly is the single most common breach of duty in these cases. Where a scan is delayed, or where a patient is sent home with pain relief and told to return if things worsen, the opportunity to operate in time can be lost.
Emergency decompression surgery and why timing matters
The treatment for cauda equina syndrome is decompression surgery to take the pressure off the affected nerves. It is an emergency operation, and the outcome depends heavily on how quickly it is carried out after the red flag symptoms appear.
Where surgery happens in time, many people recover well. Where it is delayed, the nerve damage can become permanent, and the consequences — lasting bladder and bowel problems, sexual dysfunction, altered sensation and mobility problems — can affect every part of daily life. That difference between the outcome someone had and the outcome they should have had is what a claim is built on.
Slow-onset cauda equina syndrome
Cauda equina syndrome does not always come on suddenly. In some people symptoms build over days or weeks, and this slower presentation is more easily missed or put down to something else.
A gradual onset does not weaken a claim. The question is the same: were the warning signs there, should a competent clinician have recognised them, and would earlier action have produced a better outcome?
Living with cauda equina syndrome
For people left with lasting symptoms, the effects reach well beyond the physical. Continence problems, loss of sexual function, chronic pain and reduced mobility affect work, relationships and independence, and the psychological impact is often considerable.
This matters to your claim as well as to your recovery. Compensation should reflect the full picture — not only the injury itself, but the care you need, the earnings you have lost, and the adaptations and equipment that will help you live as independently as possible.
Treatment for cauda equina syndrome
Cauda equina syndrome is a medical emergency. It requires urgent assessment and treatment, often within a matter of hours. If treatment is delayed then the consequences can be devastating. Claims typically arise where the treating clinicians failed to diagnose the cauda equina syndrome, or there was a delay in investigation or treatment.
Can I make a claim for compensation arising from cauda equina syndrome?
You could be entitled to compensation if substandard medical care caused injury or a poor outcome. A claim may allow you to recover damages for the harm suffered and for financial losses that result from it.
In broad terms, a medical negligence claim requires proof of two matters.
First, that the treatment did not meet a reasonable standard of care. Examples include:
- a diagnosis being delayed or wrong
- an error made by a medical professional
- treatment being carried out incorrectly or inappropriately
Second, that the failure in treatment led to injury. This may amount to a new injury or a worsening of a condition you already had.
If you feel your treatment was not up to the proper standard, or you are uncertain whether you have a claim, our medical negligence team can discuss this with you in more detail.
Will my cauda equina syndrome claim be successful?
We assess the strengths and potential difficulties of your case throughout the claims process. This means that if there are concerns about liability or the likely outcome, we can raise them with you as early as we can. Clear communication helps you stay informed and decide how you want to proceed.
How can cauda equina syndrome compensation support my recovery?
In a medical negligence claim, compensation is intended to restore you, as far as possible, to the position you would have been in had the negligent treatment not occurred. That can include compensation for the injury itself and for financial losses, both past and future, such as ongoing treatment or rehabilitation costs.
The losses that arise in these cases vary from person to person, so your claim should be tailored to your own circumstances.
Where a claim succeeds, compensation can ease financial pressure and help you obtain advice, treatment, and support that may assist your continued recovery.
