How to get a jersey finger !!

Which finger is most likely to be affected with disruption of the flexor digitorum profundus tendon (also known as a jersey finger)?

• A) Thumb
• B) Index finger
• C) Third finger
• D) Ring finger
• E) Fifth finger (“pinky”)

Answer and Discussion

The answer is D.

Disruption of the flexor digitorum profundus tendon, also known as jersey finger, commonly occurs when an athlete's finger catches on another player's clothing, usually while playing a tackling sport such as football or rugby.
The injury causes forced extension of the DIP joint during active flexion. The ring finger is the weakest finger and accounts for 75% of jersey finger cases.
