Keeping the limb secure during surgery is about immobilizing it safely to protect nerves and tissues. When a patient is under anesthesia, muscle tone relaxes and even small movements can cause the limb to shift, leading to unintended traction on nerves or compression at bony points. Using padded supports and gentle restraints keeps the limb in the correct position, maintains alignment for the procedure, and distributes pressure so nerves and circulation aren’t harmed. This prevents nerve injuries such as traction or compression injuries at common sites like the elbows or ankles, and it helps keep the surgical field stable.

Hindering access would defeat the purpose of positioning, and deliberately restricting blood flow or aiming to improve drainage aren’t goals of limb securing. These would be unsafe and ineffective.
