CausesA 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..
Risk FactorsA risk factor is something that increases your chance of getting an injury. Risk factors for a finger sprain may include:

- Stable joint
- Partial tearing of ligament tissue
