A finger sprain is the stretching or tearing of ligaments that support the small joints of the finger. Ligaments are strong bands of tissue that connect bones to each other.

A finger sprain usually results from a blow to the finger causing the finger to bend too much or in the wrong direction. This often occurs during athletic activity when an athlete jams a finger into another person, the ball, or piece of equipment. Finger sprains may also occur in other situations, such as falling on the hand..
