Insights
Pediatric brachial plexus avulsion from trauma is rare. This case highlights a severe, overlooked unilateral phrenic nerve palsy causing respiratory distress in a child with brachial plexus injury.
Area of Science:
- Pediatric Traumatology
- Neurology
- Respiratory Medicine
Background:
- Brachial plexus injuries are common in adult multitrauma but rare in children.
- Motor vehicle accidents and pedestrian strikes are leading causes of pediatric brachial plexus palsy.
- Associated phrenic nerve palsy occurs in 10-20% of brachial plexus trauma cases, often asymptomatic unilaterally.
Observation:
- A rare pediatric case of severe unilateral phrenic nerve palsy with respiratory distress.
- The injury was associated with brachial plexus avulsion resulting from multitrauma.
- This highlights a potentially overlooked complication in pediatric trauma patients.
Findings:
- Severe unilateral phrenic nerve palsy can occur with brachial plexus avulsion in children.
- Respiratory distress may be the presenting symptom of this rare complication.
- Prompt recognition is crucial for appropriate management.
Implications:
- Emphasizes the need for heightened awareness of phrenic nerve involvement in pediatric brachial plexus injuries.
- Suggests respiratory evaluation should be considered in pediatric multitrauma with suspected brachial plexus injury.
- Underscores the rarity and potential severity of combined brachial plexus and phrenic nerve avulsion in children.
Abstract:
Although brachial plexus injury occurring during multitrauma is frequent in adults, it is rarely observed in childhood. The most common cause of pediatric traumatic brachial palsy is motor vehicle accidents followed by pedestrian struck. Generally, phrenic nerve palsy accompanying brachial plexus trauma is observed in 10% to 20% of cases, but it is overlooked because unilateral injuries are frequently asymptomatic. Severe unilateral phrenic nerve palsy accompanying brachial plexus avulsion is very rare. Here, we present a pediatric case of unilateral phrenic nerve palsy associated with respiratory distress and brachial plexus avulsion due to multitrauma.

Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
