What is the Flexor Digiti Minimi Brevis?
The flexor digiti minimi brevis is a small muscle in your hand that helps you bend your pinky finger. It sits on the palm side of your hand, along the outer edge below the pinky, in the padded area often called the “pinky side” of the palm. When it contracts, it flexes the pinky mainly at the knuckle where the finger meets the hand, helping you curl the pinky toward your palm.
