Erb's Palsy Claims: When Shoulder Dystocia Is Negligently Managed

Erb's palsy is a brachial plexus injury that affects movement in one arm, ranging from temporary weakness to permanent paralysis. Where it results from a missed antenatal warning or negligent delivery, a claim can be brought on the child's behalf.

What is Erb's palsy?

Short answer

Erb's palsy is injury to the upper brachial plexus — the C5/C6 nerve roots that control shoulder, upper arm and elbow movement. It most commonly arises when a baby's anterior shoulder becomes impacted behind the mother's pubic bone during delivery (shoulder dystocia) and traction on the head stretches, tears or in severe cases avulses the nerve roots from the spinal cord.

When is delivery care negligent in Erb's palsy?

Erb's palsy negligence typically falls into one of these categories:

Failure to recommend or offer a Caesarean section

Where antenatal risk factors made shoulder dystocia foreseeable — maternal diabetes, foetal macrosomia, a previous delivery complicated by shoulder dystocia, certain maternal anatomical features — a competent clinician should raise the risk and offer planned Caesarean. Failure to do so, where injury then follows, can ground the claim.

Failure to honour a Caesarean request

Where a mother specifically requested Caesarean and was refused without adequate clinical justification, and shoulder dystocia then caused brachial plexus injury, the refusal itself may be the negligent act.

Negligent management during delivery

Applying excessive downward traction on the baby's head, twisting or rotating the head inappropriately, applying fundal pressure (which can worsen impaction), or failing to follow the RCOG manoeuvres in the correct sequence. The negligence is not that shoulder dystocia occurred — it is how it was handled.

Failure to recognise risk factors in real time

A prolonged second stage, a difficult instrumental delivery, or a 'turtle sign' (the baby's head retracting against the perineum) all signal possible shoulder dystocia. Failure to act on these signs and call for senior help can extend the impaction and worsen the brachial plexus injury.

What is the standard of care when shoulder dystocia occurs?

RCOG Green-top Guideline 42 sets the benchmark. The first response is the McRoberts manoeuvre (the mother's legs are hyperflexed against her abdomen by two attendants) with suprapubic pressure applied by a third — a combination that resolves the majority of cases without injury. If that fails, internal manoeuvres follow: Rubin II to rotate the posterior shoulder forward, and delivery of the posterior arm. Fundal pressure and excessive lateral traction on the head are specifically warned against. NHS Litigation Authority data cited in the guideline found that 46% of shoulder dystocia injuries were associated with a poor standard of care.

How do severity and prognosis affect an Erb's palsy claim value?

Erb's palsy outcomes vary widely. At the milder end, neuropraxia involves bruising or stretching of the nerve without structural rupture, and spontaneous recovery within three to six months is common. Further along the spectrum, nerve rupture or root avulsion produces permanent deficit that cannot fully recover through natural healing — surgical nerve grafting or tendon transfer may improve function but rarely restores it to normal. Severity is assessed by neonatal clinical examination, EMG and nerve conduction studies, and MRI of the brachial plexus, and directly shapes both general damages and the special-damages schedule.

What evidence will be needed for an Erb's palsy claim?

  • The full antenatal record showing what risk factors were identified and discussed.
  • Intrapartum notes, the CTG trace, and the delivery contemporaneous notes — including the timed sequence of manoeuvres applied.
  • The neonatal examination and any record of arm movement, grip and reflexes at birth.
  • EMG / nerve conduction studies and brachial plexus MRI imaging.
  • Independent expert evidence from a consultant obstetrician, midwife, paediatric neurologist and (where surgery is in issue) a brachial plexus surgeon.

How much compensation is awarded?

NHS Resolution 2022/23 data records the average total Erb's palsy negligence settlement at £809,485. The Judicial College Guidelines 18th edition (April 2026) contains brackets for brachial plexus injury graded by severity — applied alongside the special-damages schedule for therapy, surgery, adaptive equipment, and any loss of future earning capacity where the injury affects the dominant arm or restricts career options.

Under the CFA Order 2013, the 25% success-fee cap applies only to general damages and past financial losses. Future losses — projected therapy, surgical costs and lost earnings — are paid in full and entirely outside the cap.

Funding and time limits

Erb's palsy claims are typically funded by a Conditional Fee Agreement — no upfront costs, no fees if the claim fails. Legal aid is not available for Erb's palsy alone, but does apply where the child also suffered severe neurological brain injury within eight weeks of birth (see the cerebral palsy claims guide). The child's own three-year limitation clock under section 28 of the Limitation Act 1980 only begins on their 18th birthday — but acting far earlier through a parent or litigation friend preserves evidence and opens the door to interim payments. For maternal injuries sustained during the same delivery, the standard three-year rule applies from the date of injury or knowledge.

Frequently asked questions

Does every Erb's palsy injury involve negligence?

No. Some degree of brachial plexus stretch can occur even in well-managed deliveries. The legal question is whether the care fell below the standard a reasonably competent maternity team would have provided — for example by missing antenatal risk factors, refusing a justified request for Caesarean, or applying excessive traction during shoulder dystocia — and whether that failure caused or materially contributed to the injury.

What does the RCOG shoulder dystocia protocol require?

RCOG Green-top Guideline 42 sets out a structured drill: call for help, McRoberts manoeuvre with suprapubic pressure first, then internal manoeuvres (Rubin II, Wood's screw, delivery of the posterior arm). Fundal pressure and excessive lateral traction on the head are specifically warned against. Deviation from the protocol is the most common breach pleaded in Erb's palsy claims.

Can a Montgomery consent failure ground an Erb's palsy claim on its own?

Yes. Where antenatal risk factors for shoulder dystocia existed (maternal diabetes, foetal macrosomia, previous shoulder dystocia), the clinician must discuss them and offer planned Caesarean. A failure to have that conversation can be the standalone negligent act under Montgomery v Lanarkshire Health Board [2015] UKSC 11 — separate from how the delivery itself was managed.

How much compensation is awarded for Erb's palsy?

NHS Resolution 2022/23 data records the average total Erb's palsy negligence settlement at £809,485. General damages are assessed against the Judicial College Guidelines brachial plexus brackets; the actual figure varies enormously between full recovery within months and permanent complete paralysis. Special damages (therapy, surgery, equipment, lost earnings) often dominate in permanent cases.

How long do parents have to bring an Erb's palsy claim?

The child's own three-year limitation period does not start until the 18th birthday under section 28 of the Limitation Act 1980 — proceedings can be issued up to age 21. A parent or litigation friend should bring the claim much earlier so delivery records, CTG traces and maternity notes are still complete and interim payments for therapy can be applied for.
