§ GUIDE · CAUDA EQUINA

Cauda equina claims,
and what decides them.

Cauda equina syndrome is a surgical emergency: pressure on the nerves at the base of the spine that can cause permanent bladder, bowel and sexual dysfunction within hours. Claims are common and often unsuccessful. These two judgments show precisely why.

§ THE RED FLAGS

The symptoms that turn back pain into an emergency.

Where these appear, the expected response is urgent imaging and, if compression is confirmed, decompression surgery at the earliest opportunity. Delay costs function that does not come back. That is why so much of the litigation turns on a single consultation and a single scan.

  • Numbness in the saddle area: the parts of you that would touch a saddle.
  • New difficulty passing urine, loss of the sensation of needing to go, or incontinence.
  • Bowel disturbance or loss of control.
  • Numbness, weakness or sciatica affecting both legs rather than one.
  • Loss of sexual sensation.

§ WHAT WAS ASKED, AND WHAT WAS ANSWERED

Safety-netting questions decide GP claims.

In Hepworth v Dr Coates [2025] EWHC 1907 (KB) a 27-year-old flight attendant saw her GP with severe back and leg pain, having mentioned perianal numbness in a message two days earlier. She had emergency decompression surgery four days after the consultation and was left with permanent bladder dysfunction requiring self-catheterisation, bowel dysfunction, neuropathic pain and foot drop. Her schedule of loss claimed special damages of more than £5 million.

The judge accepted that the GP asked the right red-flag questions and that the patient answered no to them on the day. The alleged breach of duty was not made out and the claim failed. The case turned on contemporaneous notes and messages, on both sides.

§ WHAT THE SCAN SHOWED

If it was not there to be seen, missing it is not negligence.

In Spellman v Portsmouth Hospitals University NHS Trust [2024] EWHC 2011 (KB) the claimant alleged a radiologist missed cauda equina compression on an MRI taken the day after a fall, delaying diagnosis until private surgery six days later. Damages had been agreed at £300,000, payable only if she proved breach and causation.

Sweeting J examined the imaging evidence and concluded there was no radiological evidence of cauda equina compression. Because it was not there to be found, reporting the scan as showing mild stenosis was an accurate assessment rather than a breach of duty. The agreed £300,000 was never paid.

§ WHAT THIS MEANS IN PRACTICE

Records first, then experts, then the claim.

Write down what you reported

Your account of which red flags you described, and when, is the heart of the case. Messages to the surgery, 111 records and triage notes can be decisive.

Get the imaging, not just the report

Where the allegation is a missed finding, the court looks at the scan itself with expert radiology evidence, as it did in Spellman.

Agreeing damages does not agree liability

Parties often agree the value and fight only breach and causation. Losing on liability means recovering nothing, however large the agreed figure.

Act quickly on the time limit

Usually three years from the treatment or from when you first knew something had gone wrong. Cauda equina claims need expert evidence that takes months to obtain.

§ THE JUDGMENTS BEHIND THIS GUIDE

Two cauda equina judgments.

Both claims failed, one against a GP and one against a hospital radiology department, and both show what the court examines.

Claim failed

Karen Spellman v Portsmouth Hospitals University NHS Trust

[2024] EWHC 2011 (KB)·2024·Liability decided at trial

Ms Spellman alleged a hospital radiologist missed cauda equina compression on an MRI scan taken the day after her fall, delaying diagnosis until private surgery six days later. Damages had been agreed at £300,000 if she won, but the judge found the scan showed only mild stenosis with no compression to be found, so the claim failed.

Parties sometimes agree the damages figure in advance and fight only liability, so a claimant who loses on breach of duty recovers nothing. Expert evidence on what the scan actually showed was decisive.

Claim failed

Rebecca Hepworth v Dr Amanda Coates

[2025] EWHC 1907 (KB)·2025·Liability decided at trial

A 27-year-old flight attendant saw her GP with severe back and leg pain, having mentioned perianal numbness in a message two days earlier; she had emergency surgery for cauda equina syndrome four days after the consultation. The judge accepted that the GP asked the right red-flag questions and that the patient answered no, so there was no breach of duty.

In cauda equina cases the court looks closely at what safety-netting questions the GP actually asked and what the patient answered on the day. Contemporaneous notes and messages matter greatly for both sides.

§ QUESTIONS

Common questions

What are the cauda equina red flags?

Saddle numbness, new bladder or bowel disturbance, bilateral leg symptoms and loss of sexual sensation. Together with back pain they call for urgent imaging and, if compression is found, decompression surgery at the earliest opportunity.

My GP did not refer me. Is that automatically negligent?

No. The court looks at what was asked and what you answered at the time. In Hepworth v Dr Coates the judge found the GP asked the red-flag questions and the patient answered no, so there was no breach of duty.

The MRI was reported as normal but I have permanent damage. Can I claim?

Only if the compression was visible on the scan. In Spellman v Portsmouth Hospitals the judge found there was nothing to see, so the report was accurate. Expert radiology evidence on the images themselves is essential.

How much are cauda equina claims worth?

It depends entirely on the residual disability, care needs and lost earnings. The two claimants here pleaded £300,000 and over £5 million respectively, and both recovered nothing because liability was not proved.

How quickly should surgery happen?

Cauda equina compression is treated as an emergency, with decompression at the earliest opportunity once confirmed. The precise timing is a matter for expert evidence in each case.

What should I do first if I think I have a claim?

Gather your records, including any messages to your GP surgery, and speak to a specialist solicitor early. The free assessment on this page and the first conversation with Tomlin & Partners cost nothing.
