Shoulder dystocia during delivery is one of the most serious complications that affects mothers in labour. However, unlike many other birth injuries, it is not something that can be easily anticipated in advance. Despite being a relatively rare outcome, when it does suddenly occur, the speed and skill of the attendant clinical team matters enormously.
When this kind of situation is managed well, most babies are born safely and with no lasting harm. But in the small percentage of affected deliveries, the consequences for both newborns and mothers can be devastating.
What is Shoulder Dystocia?
Shoulder dystocia occurs when a baby’s head has emerged during delivery but one shoulder becomes stuck behind the mother’s pubic bone, preventing the birth from progressing normally.
This complication creates an immediate danger because, while the head is out, the chest remains compressed, which restricts the baby’s ability to breathe. If the umbilical cord is also compressed, oxygen flow is further restricted, which increases the severity of the situation.
Because of the speed at which this type of delivery can escalate, shoulder dystocia is classed as an urgent obstetric emergency. The clinical team’s ability to quickly recognise and respond to the warning signs is often central to the outcome.
How Common is Shoulder Dystocia in the UK?
According to the Royal College of Obstetricians and Gynaecologists (RCOG), shoulder dystocia occurs in approximately 1 in 150 vaginal births (around 0.7%) in the UK. While the numbers alone might make this seem uncommon, the real-world implication is thousands of affected families each and every year.
A common misconception regarding shoulder dystocia is that it only affects larger babies. However, around 48% of cases are said to involve babies weighing less than 4kg. Ultimately, this means that many families affected by shoulder dystocia had no prior indication that it might happen to them.
This condition is the third most common cause of obstetric litigation in the UK, highlighting not only how serious it can be, but also how often questions arise about standards of care received during childbirth.
What are the Signs and Symptoms of Shoulder Dystocia?
Because shoulder dystocia usually happens without warning at the point of delivery, the signs are often recognised by the clinical team rather than the mother. During active labour and delivery, those indicators include:
- The baby’s head being born but the body not following with the next contraction or push.
- The turtle sign; where the baby’s head appears at the birth canal and then pulls back, rather than progressing toward delivery.
- The baby’s face appears compressed or flushed at the perineum.
- Failure of the baby’s head to rotate following delivery.
- A prolonged pause between delivery of the head and delivery of the body, with a delay of over 60 seconds being a recognised clinical threshold.
A prolonged first or second stage of labour, the need for an assisted delivery (forceps or ventouse), and a large baby are also intrapartum (during labour) risk factors that will usually heighten clinical awareness.
Common Complications Resulting From Shoulder Dystocia
When shoulder dystocia is properly managed and resolved quickly, the babies involved are often born without lasting harm. However, even in cases where the clinical team acts correctly, the condition can still carry real risks for both mother and child. When care is delayed or mismanaged, those risks increase even further.
Possible Effects on the Baby
Brachial plexus injury (BPI) is the most common injury associated with shoulder dystocia in babies. BPI refers to damage caused to the network of nerves that run from the neck down to the arm and is believed to occur in approximately 1 in 10 babies who experience shoulder dystocia.
The most well-known form of BPI is Erb’s Palsy, which primarily affects the upper arm and shoulder. This type of injury can lead to weakness, limited movement, or in more severe cases, paralysis of the limb.
While around 80% of children with Erb’s Palsy make a full recovery over time, a significant minority go on to live with a permanent disability.
Those affected may require ongoing physiotherapy, surgery, and adaptations at home and school, with many experiencing lifelong challenges with practical tasks.
Other potential injuries to the baby include:
- Fractured Clavicle (Collarbone) or Humerus (Upper Arm): While these injuries often heal, they also indicate the high level of force involved.
- Hypoxic-ischaemic Encephalopathy (HIE): HIE is a brain injury caused by oxygen deprivation during the delayed delivery. In moderate to severe cases this can result in lasting neurological conditions, such as cerebral palsy.
- Klumpke’s Palsy: A less common brachial plexus injury affecting the lower arm and hand.
Possible Effects on the Mother
Shoulder dystocia doesn’t only affect newborns; it also poses serious physical and mental risks to the mother. These include:
- Postpartum Haemorrhage (PPH): Heavier-than-normal bleeding after birth. The RCOG notes this occurs in approximately 11% of shoulder dystocia cases, sometimes requiring a blood transfusion or surgical intervention.
- Third/Fourth-degree Perineal Tears: Severe tearing that extends to the muscle and tissue around the back passage, affecting approximately 3.8% of shoulder dystocia births.
- Uterine Rupture: A serious and potentially life-threatening tear in the wall of the uterus.
- Psychological Trauma: The impact of an emergency birth can have a lasting emotional effect on mothers, often manifesting itself as post-traumatic stress disorder (PTSD), anxiety, and postnatal depression.
How Should Shoulder Dystocia Be Managed During Delivery?
All midwives and obstetricians are required to train regularly in order to manage instances of shoulder dystocia. When it does happen, there are established clinical procedures the team should follow without delay.
The first, and most widely used, technique is the McRoberts Manoeuvre. Here, the mother’s thighs are flexed toward her chest to flatten the lumbar spine and increase the functional diameter of the pelvis. This is often used alongside suprapubic pressure, which is when firm downward pressure is applied just above the pubic bone to dislodge the shoulder.
If these steps don’t resolve the situation, further manoeuvres include:
- The Gaskin Manoeuvre: Asking the mother to move onto all fours to change the angle of the pelvis.
- Internal Rotational Manoeuvres: The clinician manually rotates the baby’s shoulders from inside.
- Delivery of the Posterior Arm: The baby’s rear arm is carefully guided out to reduce the width of the shoulders.
- Episiotomy: This is a surgical cut that widens the vaginal opening, which can give better access for internal manoeuvres
In the most serious cases, an emergency caesarean section or deliberate fracture of the baby’s collarbone may be necessary to protect their life.
Speed, clinical understanding, and teamwork are crucial when shoulder dystocia becomes apparent. Any delay in recognising the condition, calling for help, or applying the correct manoeuvres can increase the risk of harm to both mother and baby.
When Does Shoulder Dystocia Become Negligence?
This can be one of the most important questions for families trying to make sense of what happened during birth. The fact that shoulder dystocia occurred is not itself evidence of clinical negligence, as it’s usually an unforeseeable complication. However, the way it was managed at the time is a crucial detail.
Shoulder dystocia becomes a potential negligence matter when there has been a breach of the duty of care that caused harm. According to NHS Resolution data, 46% of brachial plexus injuries associated with shoulder dystocia were linked to substandard care.
Common scenarios when a family may be able to bring a shoulder dystocia negligence claim include:
Before delivery:
- Failure to identify and discuss risk factors during antenatal care. These range from maternal diabetes and obesity, to having previously delivered a large baby.
- Failure to offer an induction or planned caesarean section where risk factors were present and documented.
- Failure to obtain informed consent. The landmark case Montgomery v Lanarkshire Health Board [2015] established that women must be told about material risks relevant to their individual circumstances, including the likelihood of shoulder dystocia.
During delivery:
- Delayed recognition of shoulder dystocia after the turtle sign (or other warning indicators) appeared.
- Failure to call for senior support or activate the obstetric emergency protocol in time.
- Applying excessive traction to the baby’s head and neck is one of the most common causes of brachial plexus injury and is frequently cited in claims.
- Performing manoeuvres incorrectly, or in the wrong order.
- A junior clinician managing the emergency without escalating to an experienced consultant.
After delivery:
- Failure to properly assess and document the baby’s condition.
- Delay in referring for specialist neonatal review.
If any of these apply to your experience, it does not automatically mean a claim will succeed. However, it does suggest that your case deserves a careful, expert review to properly investigate what happened in the moment.
FAQs About Shoulder Dystocia
Q: Can shoulder dystocia be predicted or prevented before labour? In most cases, no. The RCOG confirms that shoulder dystocia usually occurs without warning, and conventional risk factors predict only around 16% of cases result in injury. This is precisely why it is so important that all maternity staff are trained to manage it when it does occur — and why a delayed or poor response can be relevant to a negligence claim.
Q: My baby was born with Erb’s Palsy after shoulder dystocia. Does this mean negligence occurred? Not automatically. Brachial plexus injuries can occur even when shoulder dystocia is managed perfectly. However, given that the NHSLA has linked nearly half of such injuries to substandard care, it is worth having your case reviewed by a specialist. A specialist solicitor can assess whether the clinical team followed the correct procedures and whether the injury was caused by factors within their control.
Q: What is the time limit for making a shoulder dystocia claim in the UK? For an adult claiming in relation to their own injury, the standard limitation period is three years from the date of the incident or date of knowledge. For a child’s claim, the three years does not begin until they turn 18, meaning a claim can be brought up until their 21st birthday. However, seeking legal advice early means better evidence preservation and a stronger case.
Q: Will making a claim affect my relationship with the NHS or my future care? No, you have a legal right to bring a clinical negligence claim without any negative impact on the care you or your child receive from the NHS. Many families are understandably worried about this, but NHS trusts are legally obligated to continue treating all patients equally regardless of any claim.
Q: What compensation can be claimed following a shoulder dystocia injury? Compensation in birth injury claims can cover a wide range of losses, including: pain and suffering, the cost of ongoing medical treatment and therapies, specialist equipment, adaptations to the home, educational support, loss of future earnings (for the child), and the costs of care. In serious cases involving permanent disability, awards can be substantial — reflecting the lifetime of support the child will need. Each case is assessed individually based on the specific injuries and their long-term impact.
Understanding Your Options For Shoulder Dystocia Claims
It’s important to know that, however challenging your situation might be, you don’t have to navigate this alone. There is a wide range of support available to families who experienced shoulder dystocia during delivery.
These avenues may be able to answer any urgent legal questions you currently have, as well as providing pathways to practical and emotional help.
Legal Support for Families
A specialist birth injury solicitor can review your case confidentially and at no cost. If there are grounds for a shoulder dystocia claim, most cases are pursued on a no win, no fee basis, meaning there is no financial risk to your family.
A successful claim can secure compensation for your child’s medical needs, including therapies, specialist equipment and education, care costs, and adaptations to the family home. It can also provide financial security for your child’s long-term future if they face a lasting disability. Beyond financial compensation, many families say the process of bringing a claim gave them answers — which can sometimes provide an additional degree of closure.
The time limit to bring a clinical negligence claim is generally three years from the date of the incident, or three years from the date you first connected the injury to potential negligence. Importantly, for a child’s claim, the three-year period doesn’t begin until their 18th birthday — so, for many people, there is time. Even so, taking early specialist advice tends to ensure the best chance of building a strong case.
