In Victoria, nerve damage that you were warned about, and that happened without any error, is usually not a claim. It can be a claim where a material risk was never explained to you, where the nerve was injured by the way the procedure was carried out, or where the injury was not recognised and acted on when it should have been.
Two questions decide it. The first is whether the care was reasonable, measured against what a practitioner holding that skill could reasonably be expected to do at the time (Wrongs Act 1958 (Vic) ss 48 and 58). The second is whether you were warned, which the Act treats differently: the peer professional opinion defence in s 59 does not apply to warnings (s 60).
A third hurdle catches many nerve injuries. Damages for pain and suffering need a "significant injury" — impairment of more than 5 per cent of the whole person (ss 28LB, 28LE and 28LF). A good many peripheral nerve injuries sit below it.
| Usually not negligence by itself | May support a claim | |
|---|---|---|
| Consent and warnings | A recognised risk that was explained, and that you would have accepted | A material risk never mentioned, or a question you asked answered inaccurately |
| How it was done | An injury that can occur even with reasonable care and skill | Technique, retraction or instrument use respected practitioners would not accept |
| Positioning | Standard positioning and documented checks | Prolonged or unusual positioning, no padding or pressure checks recorded |
| Injections and blocks | Pins and needles that settle after a correctly placed block | An injection outside the accepted site, or continued despite a warning sign |
| Afterwards | Symptoms examined, documented and referred without delay | Repeated reports of numbness, weakness or pain that were never investigated |
These are the questions, not a prediction about any case. Section references are to the Wrongs Act 1958 (Vic) as in force on 11 September 2026.
You were probably told the numbness would settle, and for many people it does. When it does not, the explanation you were given stops feeling like an explanation.
This article cannot tell you what treatment you need. If your symptoms are new or worsening, get advice promptly from an appropriately qualified treating practitioner. What follows is about the legal questions.
Why does a warned-of risk usually defeat a nerve damage claim?
Because the law asks whether the care was reasonable, not whether the outcome was bad. Under s 48 of the Wrongs Act, a person is not negligent in failing to take precautions against a risk of harm unless the risk was foreseeable, it was not insignificant, and a reasonable person in that position would have taken those precautions. Section 49(b) adds that a risk avoidable by doing something differently does not of itself give rise to liability. Hindsight is not the test.
Nerves sit close to the field of most operations, and they are stretched, retracted and compressed by surgery performed properly. That is why a recognised complication on its own does not establish a claim, as Known complication or medical negligence? explains. It does not establish the opposite either.
What does Wallace v Kam mean for nerve damage claims?
Wallace v Kam [2013] HCA 19 is the most directly relevant Australian authority on nerve damage after surgery. A patient had lumbar spine surgery carrying two distinct risks: temporary nerve damage to the thighs, called neurapraxia, and a one-in-twenty chance of permanent and catastrophic paralysis. The first materialised. The second did not.
The trial court found the surgeon had negligently failed to warn of the neurapraxia risk, but that the patient would have had the operation anyway if warned of it. So he argued he should have been warned about the paralysis risk, and would then have refused surgery.
The High Court dismissed the appeal unanimously on 8 May 2013. Liability did not extend to the injury actually suffered, because the patient would have gone ahead even if warned of the risk that materialised. The duty to warn protects a patient from injury whose risk is unacceptable to that patient, and he was not to be compensated for an injury whose risk he was willing to accept.
So the missing warning has to line up with the injury you suffered. Section 51 frames that as factual causation plus scope of liability, and s 51(3) decides what you would have done subjectively.
What if you were never warned at all?
Then the question is what counts as a material risk. The test comes from Rogers v Whitaker (1992) 175 CLR 479, restated by the High Court in Chappel v Hart: a risk is material if a reasonable person in the patient's position, if warned, would be likely to attach significance to it, or if the practitioner is or should reasonably be aware that this particular patient would be likely to attach significance to it.
The second limb is the one people miss, because it makes what you said in the consultation legally relevant. Chappel v Hart [1998] HCA 55 turned on exactly that. A patient having surgery to remove a pharyngeal pouch told the surgeon she did not want to end up with a damaged voice. She was warned the oesophagus might be perforated, but not that a perforation could lead to infection, damage to the laryngeal nerve and paralysis of a vocal cord. That is what happened, and the High Court held by majority that causation was established. The risk she should have been warned about was the risk that materialised.
Section 50 says the duty is satisfied by taking reasonable care in giving the warning, and s 60 removes the peer professional opinion defence from warnings entirely — a surgeon cannot answer a failure-to-warn allegation by saying other surgeons would not have mentioned it either. A signed form does not settle this, as Signing a consent form explains: it records that a conversation happened, not what was said.
What standard is the surgeon or anaesthetist measured against?
Not perfection, and not your outcome. Section 58 sets the standard by what could reasonably be expected of a person possessing the skill the practitioner held out, judged as at the date of the alleged negligence. Section 59 then gives a defence: a professional is not negligent if they acted in a manner widely accepted in Australia at the time by a significant number of respected practitioners in the field as competent professional practice. Four qualifications matter.
- Peer professional opinion cannot be relied on if the court determines the opinion is unreasonable (s 59(2)).
- Where respected practitioners differ, any one of those views may be relied on (s 59(3)).
- An opinion need not be universally accepted to count as widely accepted (s 59(4)).
- None of it applies to warnings, because of s 60.
A claim built on technique rather than consent therefore needs an independent specialist in the same field to say what was done fell outside what respected practitioners accept.
What about nerve damage after an epidural, a spinal or a nerve block?
The same two questions apply, and the anaesthetic record usually decides them. An assessment looks for:
- how the block was sited, and what technique or guidance was used;
- whether severe pain or pins and needles during insertion was noted, how many attempts were made, and what was done; and
- what happened when new weakness or numbness was first reported.
Delayed recognition is its own category, separate from how the block was performed. It raises the question that runs through misdiagnosis and delayed-diagnosis claims: not whether something went wrong, but whether the response was reasonable. Nerve injury after dental treatment follows the same structure with a different anatomy, and has its own guide on dental nerve damage claims.
Is your nerve injury severe enough to claim in Victoria?
This is where a good many nerve damage claims stop. Under s 28LE you cannot recover damages for non-economic loss — pain and suffering, loss of enjoyment of life — unless you have suffered a "significant injury". Section 28LF defines that as whole person impairment satisfying the threshold level, assessed by an approved medical practitioner or determined by a Medical Panel. Section 28LB sets the threshold level:
- for an injury other than a psychiatric or spinal injury, impairment of more than 5 per cent;
- for a spinal injury, impairment of 5 per cent or more; and
- for a psychiatric injury, impairment of 10 per cent or more.
The assessment uses the A.M.A. Guides (s 28LH). The Act does not define "spinal injury", so which limb applies to an injury arising from spinal anaesthesia is a question for the assessment.
Being plain about it: a patch of numbness on the thigh, or a block that has partly recovered, often assesses below the threshold. A foot drop that has not resolved, a hand that cannot grip, a permanently paralysed vocal cord are a different proposition. The threshold applies only to pain and suffering; financial losses are assessed separately, and what compensation you can claim sets out the categories.
How long do you have to bring a claim?
Section 27D of the Limitation of Actions Act 1958 (Vic) gives you whichever expires first: three years from the date the cause of action was discoverable by you, or twelve years from the act or omission. Where the injured person was under a disability at that date, s 27E gives six years from the discoverable date, or the same twelve-year long stop.
Nerve injuries are a common way for the clock to run out quietly, because people wait to see whether symptoms settle. Waiting past the limitation period is not recoverable. Time limits for medical negligence claims has the detail.
What do the records have to show?
Nobody can answer the technique question from your description. The record is the evidence, and the documents that usually decide it are:
- the consent form and pre-operative notes, including anything recorded about your questions;
- the operation report in full, with any note of nerve identification or difficulty;
- the anaesthetic record, any block or epidural chart, and positioning and pressure-area documentation;
- post-operative nursing and neurological observations, and every entry recording when you first reported numbness, weakness or pain; and
- referrals and letters back, nerve conduction studies, electromyography and imaging.
You are entitled to all of it, without giving a reason. How to get your medical records in Victoria sets out how, from whom, and how long it should take.
Get your nerve injury assessed
Organising a hospital file, reading an anaesthetic chart against an operation report, and getting an independent specialist to say whether the standard was met — that is the expensive part of finding out, and why claims of this size are often turned away. If a firm has already said no, that may have been a decision about the economics of investigating rather than a conclusion that the care was reasonable, a distinction Another lawyer rejected your claim explains.

Common questions
Can you claim for nerve damage after surgery if you were told it was a known risk?
Often not, but being told is not the end of it. If the risk was explained, it happened without any error, and you would have gone ahead anyway, there is usually no claim. What still has to be checked is whether the warning covered the risk that actually happened, whether the procedure met the standard expected in that field, and whether your symptoms were investigated when you reported them.
What is the impairment threshold for a nerve damage claim in Victoria?
For damages for pain and suffering, section 28LB of the Wrongs Act 1958 (Vic) sets the threshold level at impairment of more than 5 per cent of the whole person for an injury other than a psychiatric or spinal injury, 5 per cent or more for a spinal injury, and 10 per cent or more for a psychiatric injury. This is the position as at 11 September 2026, under version 130 of the Act.
How long do you have to claim for nerve damage in Victoria?
Section 27D of the Limitation of Actions Act 1958 (Vic) gives you whichever period expires first: three years from the date the cause of action was discoverable by you, or twelve years from the act or omission. Discoverable is defined in section 27F, and turns on when you knew or ought to have known that the injury had occurred, that it was caused by someone's fault, and that it was serious enough to justify an action.
