Anatomy of the brachial plexus

Area of Science:

• Anatomy
• Neurology
• Pediatrics

Background:

• The brachial plexus is a critical neural network for upper limb function.
• Obstetrical brachial plexus palsy (OBPP) requires precise anatomical knowledge for effective management.
• Clinical evaluation of OBPP relies on understanding the relationship between symptoms and nerve injury sites.

Purpose of the Study:

• To review the detailed anatomy of the brachial plexus.
• To correlate clinical presentations of OBPP with specific anatomical injury levels.
• To provide clinicians with actionable information for diagnosing and treating OBPP.

Main Methods:

• Review of anatomical literature on the brachial plexus.
• Correlation of reported clinical findings in OBPP with anatomical injury locations.
• Synthesis of information to guide clinical assessment.

Main Results:

• Detailed anatomical mapping of the brachial plexus from roots to terminal nerves.
• Identification of characteristic physical findings associated with injuries at different levels of the brachial plexus.
• Established correlation between specific clinical signs and the anatomical site of brachial plexus injury.

Conclusions:

• A comprehensive understanding of brachial plexus anatomy is essential for accurate diagnosis of OBPP.
• Clinical examination findings can effectively localize the level of brachial plexus injury.
• This knowledge facilitates targeted treatment planning and improves patient outcomes in OBPP.
