High-value Cauda Equina Syndrome (CES) claims don’t usually fail because there isn’t enough evidence.

They fail because the wrong expert was instructed too early, or the right expert was never found at all.

We recently supported a claimant solicitor facing exactly this situation.

The Risk

The case had reached a critical stage, but progress had stalled due to:

• Conflicting expert opinions on causation
• Multiple experts declining instruction
• No clear position on whether earlier intervention would have altered outcome
• Ongoing uncertainty around quantum, particularly future care and functional loss

At this point, the risk wasn’t delay - it was drift.

Without a defensible causation position, the case risked:

• Being undervalued
• Relying on assumptions that wouldn’t withstand challenge
• Incurring further cost through repeated or supplementary reports
• Weakening at negotiation or joint expert discussion

What Was Actually Going Wrong

On review, the issue wasn’t the medical records - it was the mismatch between the case and the expert being sought.

The experts previously approached were:

• Too generalist, lacking direct CES surgical experience
• Unable to confidently address the causation threshold (i.e. whether earlier decompression would have changed neurological outcome)
• Focused on clinical commentary, without translating findings into functional impact or quantum

This is where CES cases commonly fail.

Not on breach alone - but on the inability to connect delay → outcome → long-term loss.

What INNEG Did Differently

Instead of continuing the cycle of instruction and refusal, we reframed the problem.

1. Defined the real evidential gap
The key issue wasn’t timing in isolation - it was whether the delay crossed the threshold where outcome became irreversible.

2. Targeted the correct sub-specialist
We identified consultants with:

• Direct experience performing CES decompression surgery
• A track record of addressing causation in medico-legal settings
• The ability to engage with conflicting expert opinion

3. Screened for defensibility, not availability
Each expert was vetted for their ability to:

• Justify opinion under challenge
• Address competing interpretations of the clinical timeline
• Provide clear reasoning on neurological prognosis

4. Linked clinical opinion to quantum from the outset
Crucially, the expert needed to bridge:

• Neurological deficit → functional limitation (bladder, bowel, mobility)
• Functional limitation → care, rehabilitation, and long-term cost

This avoided the need for further instructions, addendum reports, or gaps later in the claim.

The Outcome

Within 48 hours, the right expert was identified and instructed.

The impact was immediate:

• A clear, defensible position on causation was established
• The relationship between delay, decompression, and outcome was properly evidenced
• The claim moved forward with a grounded basis for quantum, rather than assumption

The case shifted from uncertain and fragmented to clinically coherent and strategically viable.

The Reality for CES Claims

Delay alone doesn’t win these cases.

What matters is whether your expert can answer:

• At what point was neurological damage likely irreversible?
• Would earlier intervention have changed outcome, and on what basis?
• How does that translate into long-term function, care, and loss?

If those links aren’t made clearly, the case is exposed.

Why It Matters Who You Instruct

In complex claims, instructing the wrong expert isn’t a neutral decision.

It leads to:

• Delays that don’t move the case forward
• Reports that can’t support causation
• Additional cost through re-instruction
• Weakened positioning at negotiation

INNEG prevents that.

Not just by supplying names - but by ensuring the expert you instruct can withstand scrutiny and actually support the case you’re building.
