Insights
Early surgery for birth-related brachial plexus injuries in infants can significantly improve arm function. Over 90% of infants with upper brachial plexus lesions showed neurological improvement after early reconstruction by 9 months.
Area of Science:
- Pediatric Orthopedics
- Neonatal Surgery
- Neurology
Background:
- Birth-related brachial plexus injuries affect numerous infants, potentially leading to long-term functional deficits.
- Timely intervention is crucial for optimizing neurological recovery in affected neonates.
Purpose of the Study:
- To evaluate the efficacy of early surgical reconstruction for infants with birth-related upper brachial plexus injuries.
- To compare outcomes between surgically treated infants and a conservatively managed control group.
Main Methods:
- Retrospective review of 116 infants with birth-related brachial plexus injuries.
- Selection of 28 infants with upper brachial plexus lesions and no improvement by 4 months for early surgery (mean age 5 months).
- Comparison with a control subgroup of 44 infants managed conservatively.
Main Results:
- Over 90% of infants undergoing early brachial plexus reconstruction showed significant neurological improvement by 9 months post-surgery (p < 0.05).
- The conservatively managed group also demonstrated neurological improvement by 4 months and continued improvement at 1 year.
- Early surgical intervention yielded high rates of functional recovery in non-improving cases.
Conclusions:
- Early surgical reconstruction is a highly effective treatment for infants with birth-related upper brachial plexus injuries unresponsive to conservative management by 4 months of age.
- Prompt surgical intervention can lead to substantial neurological recovery and improved arm function in this vulnerable population.
Abstract:
The authors review the cases of 116 infants treated consecutively for birth-related brachial plexus injuries. Twenty-eight infants with upper brachial plexus lesions who showed no neurological improvement by 4 months of age were selected for early surgical reconstruction (at a mean age of 5 months). Neurological improvement of the affected arm was observed in more than 90% (p < 0.05) of the children examined longer than 9 months after brachial plexus reconstruction. A conservatively managed control subgroup of 44 children, first examined at less than 3 months of age, demonstrated neurological improvement by 4 months of age and continued to show improvement at 1 year of age. Early surgical reconstruction is recommended for infants with birth-related upper brachial plexus injury who show no neurological improvement by the age of 4 months.
