What if your newborn couldn’t move their arm right after birth? For any parent, that’s a terrifying thought. When a baby enters the world, we expect all their little limbs to work perfectly. But sometimes, complications during delivery can hurt the delicate nerves in a baby’s shoulder, leading to what doctors call a brachial plexus injury at birth.
If you’re a parent looking for answers, you’re not alone. This blog, written by Dr. Chandril Chugh, a US-trained neurologist, breaks down everything you need to know about this condition.
In this blog, we will explain what causes a brachial plexus injury at birth, what signs to look for, what recovery looks like, and what parents can do to help. We will also look at the latest treatments and research helping babies recover better.
What is a Brachial Plexus Injury at Birth?
The brachial plexus is a group of nerves that starts near the neck and goes down into the shoulder and arm. These nerves help move the muscles and feel things in the arm, hand, and fingers. A brachial plexus injury at birth happens when these nerves are stretched, torn, or pulled away from the spinal cord during delivery.
This kind of injury often occurs when the baby’s shoulder gets stuck during birth, or if the baby is very large, making delivery harder. The more pressure on the baby’s shoulder, the higher the risk of nerve damage.
How Does This Nerve Injury Occur During Delivery?
Several events during labor can damage the nerves of the brachial plexus:
Common causes:
- Shoulder dystocia: when the baby’s shoulder gets stuck behind the mother’s pelvic bone.
- Breech delivery: when the baby is delivered feet or bottom first.
- Large birth weight: babies weighing more than 4,000 grams (about 8.8 pounds) are more likely to suffer this injury.
Types of injuries include:
- Erb’s palsy in newborns: affects the upper part of the brachial plexus, causing weakness in the shoulder and elbow.
- Klumpke’s palsy: affects the lower nerves, often causing hand and wrist problems.
- Total plexus palsy: all the nerves in the brachial plexus are affected, leading to complete paralysis of the arm.
Each of these conditions varies in severity and treatment needs.

How Common is Brachial Plexus Injury in Newborns?
Brachial plexus injury at birth is not very common, but it does happen.
According to the American College of Obstetricians and Gynecologists (ACOG), this injury occurs in about 0.5 to 2 out of every 1,000 live births.
Risk factors include:
- Prolonged labor
- Use of forceps or vacuum during delivery
- Maternal diabetes
- High birth weight
- Breech position
Here’s a quick table showing some of the data:
| Risk Factor | How It Increases Risk |
|---|---|
| Shoulder dystocia | Increases pulling on neck/shoulder during delivery |
| High birth weight (>8.8 lbs) | More difficult delivery; nerves are under more pressure |
| Breech birth | Arms may be pulled during delivery |
| Long labor | More stress and possible intervention |
What are the Signs and Symptoms Parents Should Watch For?
Early signs can be easy to miss, especially for first-time parents. Knowing what to look for is important.
How Can You Tell If Your Baby Has a Brachial Plexus Injury?
If your baby has a brachial plexus injury at birth, symptoms may show up right away or within the first few days.
Signs to look out for:
- One arm doesn’t move while the other does
- Baby does not grip with the affected hand
- Weak or limp arm hanging by the side
- No shoulder or elbow movement on one side
Severity levels:
- Mild: minor stretching of the nerve, may heal on its own
- Moderate: some damage, but still connected; needs therapy
- Severe: nerves are torn; may require surgery
When symptoms appear: Usually noticeable immediately, but sometimes they appear over the first week.
When Should You Seek a Medical Diagnosis?
If your baby shows any of the above signs, do not wait.
Early diagnosis is important because:
- Treatment works best when started early
- Helps prevent long-term weakness or disability
Doctors may use:
- Imaging (like ultrasound or MRI) to look at soft tissues
- EMG (electromyography) to test how nerves and muscles are working
Always get a pediatric neurologist to check your baby if symptoms last more than a week.
Long-Term Outlook and Prognosis
The long-term outlook for individuals with brachial plexus birth injury depends on various factors, including the severity of the injury, the effectiveness of treatment, and individual factors such as age and overall health. While some individuals may experience near-complete recovery and regain full motor function, others may have residual deficits that require ongoing care and accommodations.
It is essential to manage expectations and approach the recovery journey with patience and realistic goals. Open communication with healthcare providers, adherence to treatment plans, and ongoing therapy can greatly influence the long-term prognosis and overall quality of life for individuals with brachial plexus birth injury.
| Severity of BPBI | Potential Long-Term Outcomes |
|---|---|
| Mild | Spontaneous recovery with minimal to no long-term deficits. Ongoing rehabilitation may be required to optimize function and prevent future complications. |
| Moderate | Partial recovery with residual deficits. Ongoing therapy and supportive care interventions may be necessary for functional independence. |
| Severe | Significant and persistent motor impairment, potentially requiring ongoing medical management and adaptive strategies for daily activities. |
Individuals with brachial plexus birth injury should work closely with a multidisciplinary team, including pediatric neurologists, orthopedic surgeons, physical therapists, and occupational therapists, to determine the most appropriate treatment plan and optimize long-term outcomes.

Prognosis and Long-Term Outcomes of Brachial Plexus Birth Injury
After a brachial plexus birth injury (BPBI), the prognosis and long-term outcomes can vary depending on the severity of the injury and the effectiveness of treatment. While many infants experience spontaneous motor recovery within three to six months, others may require additional interventions for optimal outcomes. It is crucial to consider sensory outcomes and pain management in the long-term management of individuals with BPBI.
Motor Recovery
In most cases, motor recovery in infants with BPBI occurs naturally within the first six months of life. As the nerves heal, gradual improvement in muscle strength and movement becomes evident. Early intervention and dedicated physical therapy can further enhance motor recovery. However, in severe cases, where significant nerve damage has occurred, surgical procedures such as microsurgical nerve reconstruction or distal nerve transfers may be necessary to facilitate motor recovery.
Sensory Outcomes
Beyond motor function, sensory outcomes are essential in assessing the overall progress of individuals with BPBI. Sensory deficits in the affected arm can range from mild to severe and may require ongoing management. Strategies such as sensory reeducation and sensory integration therapy can help individuals with BPBI optimize their sensory function and adapt to their unique sensory challenges.
Pain Management
Pain management is a crucial aspect of the long-term care for individuals with BPBI. Nerve pain, muscle tightness, and discomfort in the affected arm are common challenges. Medications, nerve blocks, and alternative therapies such as acupuncture and massage can be effective in alleviating pain and improving quality of life for individuals with BPBI.
| Outcome | Percentage of Recovered Cases |
|---|---|
| Complete Recovery | 45% |
| Partial Recovery | 30% |
| Persistent Motor Impairment | 15% |
| Significant Motor Deficits | 10% |
Based on a study involving a large sample of infants with BPBI, the table above highlights the distribution of long-term motor recovery outcomes. It is important to note that individual outcomes may vary, and each case should be evaluated and treated accordingly.
