Supraclavicular Approach to the Brachial Plexus

Area of Science:

• Anatomy
• Neurosurgery
• Surgical Technique

Background:

• The brachial plexus (BP) is a complex network of nerves crucial for upper limb function.
• BP injuries can distort nerve pathways, making surgical dissection challenging.
• Accurate anatomical understanding is vital for successful BP surgery.

Purpose of the Study:

• To present a practical, stepwise surgical approach for supraclavicular brachial plexus dissection.
• To emphasize key anatomical landmarks and surgical considerations.
• To differentiate between pre- and postganglionic nerve root injuries.

Main Methods:

• Anatomical review based on intraoperative surgical imaging.
• Use of schematic illustrations to clarify surgical steps.
• Stepwise description of the supraclavicular dissection technique.

Main Results:

• An eleven-step protocol for supraclavicular brachial plexus dissection is detailed.
• The approach highlights relevant anatomical variants.
• Differences between pre- and postganglionic nerve injuries are discussed.

Conclusions:

• The supraclavicular dissection of the brachial plexus is a reliable surgical method.
• Consistent anatomical landmarks facilitate the procedure.
• A stepwise approach enhances surgical predictability and success.
