Which nerve is particularly associated with injuries from improper positioning of arms in surgery?

The brachial plexus is particularly associated with injuries from improper positioning of arms during surgery because this network of nerves innervates the shoulder, arm, and hand. When a patient is positioned inappropriately—such as when the arms are either excessively abducted or placed in positions that put stress on the shoulder or upper limb—there is a risk of traction or compression on the brachial plexus.

Inadequate padding, awkward shoulder positions, or excessive rotation can lead to stretch injuries or ischemia of the nerves in the plexus. These types of nerve injuries can lead to significant postoperative complications including weakness, numbness, and pain in the affected arm.

Understanding this association emphasizes the importance of proper positioning of the arms during surgical procedures to minimize the risk of nerve injuries and to ensure optimal patient care and outcomes.
