Understanding the Brachial Plexus 

The brachial plexus is a complex network of nerves that originates in the neck and upper back and extends into the arm. It plays a crucial role in controlling movement and sensation in the shoulder, arm, and hand. This intricate system is responsible for transmitting signals from the brain to these parts of the body, allowing us to perform various motor tasks. 

However, the brachial plexus is particularly vulnerable to injury, especially in newborns. Events during childbirth can sometimes result in a brachial plexus injury, causing discomfort and impairing the newborn’s ability to move their arm properly. This condition is known as neonatal brachial plexus injury or newborn brachial plexopathy. 

How does the brachial plexus function? 

The brachial plexus is formed by the intertwining of nerve roots from the spinal cord in the neck. It branches out into multiple nerves, each responsible for specific motor and sensory functions in the upper limbs. These nerves work together to facilitate movements such as reaching, grasping, and rotating the arm. 

During childbirth, the brachial plexus may be stretched or compressed, leading to injury. This can occur due to various factors, including the baby’s position, the size of the mother’s pelvis, or the use of excessive force during a difficult delivery. 

Brachial Plexus Nerves and Their Functions Nerve Function 

Axillary Controls the deltoid muscle, allowing for shoulder abduction and arm rotation Musculocutaneous Controls the biceps and brachialis muscles, facilitating flexion of the elbow Radial Controls the triceps muscle and muscles responsible for wrist and finger extension Median Controls the forearm flexor muscles and muscles responsible for thumb and finger opposition Ulnar Controls the muscles responsible for wrist and finger adduction, ulnar deviation, and fine motor skills 

Understanding the brachial plexus and its functions is essential to grasp the impact of injuries on newborns. In the following sections, we will dive deeper into the causes, risk factors, symptoms, and treatment options for brachial plexus injuries in newborns.Brachial Plexus Injury in Newborns: Causes & Care 

Causes and Risk Factors 

Brachial plexus injuries in newborns can occur due to a variety of causes and risk factors. Understanding these factors is crucial in the prevention, early detection, and treatment of infant brachial plexus injury. 

Difficult Deliveries 

Difficult deliveries, such as prolonged labor or the use of forceps or vacuum extraction, can increase the likelihood of brachial plexus trauma in newborns. The excessive pressure or stretching placed on the baby’s neck and shoulders during these procedures can damage the delicate nerves of the brachial plexus. 

Large Birth Weight 

Newborns with a high birth weight have a higher risk of experiencing brachial plexus injury. This is because their size can make it more challenging for them to pass through the mother’s birth canal, increasing the likelihood of trauma to the brachial plexus nerves. 

Maternal Diabetes 

Maternal diabetes, especially when uncontrolled, can contribute to the development of brachial plexus nerve damage in newborns. The high blood sugar levels associated with diabetes can affect fetal growth and increase the risk of complications during delivery, including brachial plexus injury. 

Other Risk Factors 

While difficult deliveries, large birth weight, and maternal diabetes are common risk factors, it is important to note that brachial plexus injuries can also occur in the absence of these factors. Factors such as breech presentation, excessive maternal weight gain, and shoulder dystocia (where the baby’s shoulder gets stuck behind the mother’s pubic bone) can also contribute to the occurrence of infant brachial plexus injury. 

Identifying these causes and risk factors early on allows healthcare professionals to provide appropriate care and interventions to minimize the impact of brachial plexus injuries in newborns. 

Cause/Risk Factor Description 

Difficult Deliveries Prolonged labor, forceps or vacuum extraction 

Large Birth Weight Higher risk for brachial plexus injury 

Maternal Diabetes Uncontrolled diabetes and impact on fetal growth 

Other Risk Factors Breech presentation, excessive maternal weight gain, shoulder dystocia Symptoms and Diagnosis 

Brachial plexus injuries in newborns can cause a range of symptoms that may vary in severity. Recognizing these symptoms is crucial for early diagnosis and intervention. 

Common Symptoms of Brachial Plexus Injuries in Newborns 

• Weakness or paralysis in the arm

In some cases, these symptoms may be accompanied by other complications, such as fractures or dislocations.Brachial Plexus Injury in Newborns: Causes & Care 

Diagnostic Process 

Diagnosing brachial plexus injuries in neonates involves a comprehensive evaluation by a healthcare professional. The diagnostic process typically includes: 

1. Medical history review: The healthcare provider will assess the pregnancy and delivery history, as well as any risk factors that may contribute to brachial plexus injury. 
2. Physical examination: The healthcare provider will conduct a thorough physical examination of the newborn, assessing muscle strength, reflexes, and range of motion in the arms. 
3. Imaging studies: In some cases, imaging studies such as X-rays, ultrasound, or magnetic resonance imaging (MRI) may be ordered to evaluate the extent of the injury and identify any associated bone or nerve damage. 

The combination of these assessments helps healthcare professionals make an accurate diagnosis and determine the most appropriate treatment plan for the infant.
