Pediatric Brachial Plexus Injury

What is Pediatric Brachial Plexus Injury?
Pediatric Brachial Plexus Injury (PBPI) refers to nerve damage in the brachial plexus, a network of nerves that control the movement and sensation of the arm and hand. PBPI typically occurs during childbirth when there is stretching or tearing of the brachial plexus nerves due to difficult deliveries or other factors. The severity of the injury can vary, ranging from mild to severe, and it may affect one or both arms.
What are the Symptoms of Pediatric Brachial Plexus Injury?
The symptoms of PBPI typically appear immediately after birth but can vary depending on the extent and location of the nerve damage. Common signs and symptoms include:
- Weakness or paralysis of the affected arm
- Lack of muscle control or coordination
- Limited range of motion in the shoulder, arm, or hand
- Numbness or loss of sensation in the affected area
How is Pediatric Brachial Plexus Injury Diagnosed?
A pediatrician or specialist will conduct a thorough physical examination to assess your child's arm movement, muscle strength, and reflexes. Diagnostic tests such as electromyography (EMG) or nerve conduction studies may also be recommended to assess nerve function and identify the extent of the injury.
What are the Different Types of Pediatric Brachial Plexus Injury?
PBPI is classified into different types based on the location and severity of the nerve damage. The classifications include:
- Stretch Injury: Mild nerve stretching with minimal or no tearing.
- Neuroma: Nerve damage resulting in a scarred nerve bundle.
- Rupture: Tearing of the nerve fibers.
- Avulsion: Complete tearing of the nerve from the spinal cord.
What Treatment Options are Available for Pediatric Brachial Plexus Injury?
The treatment approach for PBPI depends on various factors, including the severity of the injury and the specific nerves affected. However, most patients with PPI will undergo a combination of the following:
- Observation: Many PBPIs may spontaneously recover over the course of several months. As such initial treatment often consists of a period of observation in order to allow the injury time to spontaneously recover. This is often coupled with physical therapy to maintain range of motion.
- Physical Therapy: Physical therapy plays a crucial role in PBPI management. A skilled therapist will develop an individualized treatment plan to improve arm function, strength, and range of motion through targeted exercises and activities. This is done with the goal of maintaining good joint motion and muscle stretch during the period of pre-recovery immobility as well as maximizing functionality post recovery.
- Nerve Surgery: In some cases, where nerve function does not return spontaneously, surgical intervention may be necessary to repair or reconstruct the damaged nerves. Nerve grafting, nerve transfers, or other procedures may be recommended depending on the specific circumstances.
What Can I Expect During the Recovery Process?
The recovery process for PBPI varies depending on the severity of the injury and the chosen treatment approach. It's important to set realistic expectations and understand that nerve recovery may take months before any external improvement are evident. Factors that can impact recovery include the age of the child, the extent of nerve damage, and adherence to therapy. It's crucial to work closely with your child's healthcare team and follow their guidance for optimal recovery.
What will I need to do after surgery?
Patient should be immobilized in their sling for the first 2 weeks after surgery. After their first post-op exam and removal of the sling, they should begin range of motion therapy for the affected arm.
Range of motion exercises should be performed slowly and held at the end of range for at least 10 seconds. The exercises should be done at least 3 times a day with each exercise being repeated 5 times.
The exercises to be performed include:
- shoulder flexion and extension
- shoulder abduction
- elbow flexion and extension
- arm external rotation **
- wrist extension
- finger and thumb extension
- forearm supination
** External rotation is the most often underperformed, leading to stiffness
Are There Potential Complications or Long-Term Effects?
While many children with PBPI experience significant improvement in function and symptoms with proper treatment and therapy, there can be potential complications or long-term effects. These may include:
- Persistent weakness or paralysis in the affected arm
- Muscle imbalances or contractures
- Developmental delays or challenges in fine motor skills
- Psychological or emotional impact related to body image or self-esteem
Support and Resources for Families:
Coping with a pediatric brachial plexus injury can be challenging, but you are not alone. There are numerous resources and support available to help you and your family throughout this journey. Here are some avenues to explore:
Brachial Plexus Organizations and Support Groups:
Connect with national or local organizations dedicated to supporting families affected by brachial plexus injuries. These organizations often provide valuable resources, information, and opportunities to connect with other families facing similar challenges.
Educational Materials:
Educate yourself about pediatric brachial plexus injuries through reliable educational materials, books, and online resources. Here are some videos demonstrating stretching exercises as well as positioning to encourage arm movement later in the healing process.
- University of Michigan
- Stanford Children’s
Seek Mental Health Support:
Managing the emotional impact of PBPI is essential for both you and your child. Consider seeking support from therapists or counselors specializing in pediatric and family psychology. They can help address any concerns, provide coping strategies, and assist with the emotional well-being of your family.
