Question 1

What is jersey finger and why is it called that?

Accepted Answer

Jersey finger is an injury where the flexor tendon (the tendon that bends your fingertip) tears away from the bone where it attaches. It's called 'jersey finger' because it commonly occurs in rugby and football when a player grabs an opponent's jersey and their finger gets forcefully straightened while gripping. The ring finger is most commonly affected because it tends to be the last finger holding on during gripping activities.

Question 2

How is this different from mallet finger?

Accepted Answer

These are opposite injuries. Mallet finger affects the extensor tendon on the back of the finger (you can't straighten the tip), while jersey finger affects the flexor tendon on the palm side (you can't bend the tip). Mallet finger often heals with splinting, but jersey finger almost always requires surgery for good function. Jersey finger is also much less common than mallet finger.

Question 3

Do I really need surgery?

Accepted Answer

Yes, almost always. Unlike mallet finger, the flexor tendon in jersey finger usually retracts significantly into the palm or finger and won't heal on its own. Without surgery, you'll permanently lose the ability to bend your fingertip, which significantly affects grip strength and hand function. Early surgery (within 7-10 days) gives the best results.

Question 4

What happens if I wait too long for surgery?

Accepted Answer

The tendon continues to retract and scar tissue forms, making repair progressively more difficult. Within the first week: Direct repair is usually possible. After 2-4 weeks: Repair becomes more challenging. After 6-8 weeks: Direct repair is usually impossible and you may need a two-stage tendon reconstruction or joint fusion. Early treatment is critical for the best outcome.

Question 5

How long is recovery after surgery?

Accepted Answer

You'll be in a protective splint for 4-6 weeks, then begin supervised hand therapy. The tendon needs 3 months to gain significant strength, and full recovery takes 6-9 months. You can typically return to office work in 4-6 weeks, light activities in 3 months, and contact sports in 6-9 months. Hand therapy is crucial and involves special protocols to protect the repair while regaining motion.
