What It Is

Tendons are strong cords that connect muscles to bone. The tendons in your hands are used when you bend and straighten your fingers (NHS, 2025). The flexor tendons on the palm side bend the fingers, and the extensor tendons on the back of the hand straighten them. A finger tendon rupture is where one of these tendons tears or is pulled off the bone. A tendon can also be cut in an injury (American Academy of Orthopaedic Surgeons, n.d.).

A torn tendon is not a minor injury that heals with self-care. It needs to be checked by a doctor promptly.

What Causes Finger Tendon Ruptures?

  • Cuts: flexor tendon injuries most often happen from a cut on the palm side of the fingers, hand, wrist or forearm (American Academy of Orthopaedic Surgeons, n.d.). Deep cuts and bites can damage hand tendons (NHS, 2025).
  • Sport: a sudden, forceful pull on the tendon can rupture it. In "jersey finger", a player's finger catches in another player's shirt and is pulled with great force, which can pull the tendon off the bone. It happens mostly in football, rugby and wrestling, and usually affects the ring finger (American Academy of Orthopaedic Surgeons, n.d.; Leggit and Meko, 2006).
  • Strong gripping: in activities that need a lot of hand strength, such as rock climbing, tendons and the tunnels they run through can be stretched or torn (American Academy of Orthopaedic Surgeons, n.d.).
  • Health conditions: conditions such as rheumatoid arthritis weaken the tendons and make them more likely to tear. This can happen without any injury; you may simply notice that a finger no longer bends (American Academy of Orthopaedic Surgeons, n.d.; NHS, 2025).

A blow to the fingertip can also damage the tendon that straightens the end of the finger (mallet finger), which is covered in a separate sheet.

About Finger Tendons

Like a rubber band, the tendons are under tension as they connect muscle to bone. When the muscles contract, they pull on the tendons, which move the finger joints. If a tendon is torn or cut, the ends are likely to pull apart, and the gap between them means the tendon cannot heal on its own. Because the nerves and blood vessels to the fingers are very close to the tendons, they may be damaged as well, which can cause numbness (American Academy of Orthopaedic Surgeons, n.d.).

First Aid

While you are on your way to see a doctor

  • Wrap the hand firmly with a clean cloth or bandage to slow down any bleeding.
  • Rinse the wound with sterile saline if you have it, to reduce the risk of infection.
  • Apply ice or a cold pack to help reduce swelling.
  • Keep your hand raised above the level of your heart.

Don't try to exercise or stretch the finger until it has been checked, as this could make the injury worse.

Getting Diagnosed

Anyone with a suspected tendon injury should see a doctor as soon as possible. Early assessment is important, because in general the sooner a torn tendon is repaired, the better the recovery (American Academy of Orthopaedic Surgeons, n.d.). The doctor will ask you to bend and straighten your fingers, test your strength and feeling, and may order an X-ray (American Academy of Orthopaedic Surgeons, n.d.). A suspected jersey finger should be referred to an orthopaedic or hand surgeon, and the outcome is worse if treatment is delayed (Leggit and Meko, 2006).

Hand therapists, physiotherapists and occupational therapists play an important part in recovery after the injury has been diagnosed and treated. Once your surgeon and hand therapist have cleared you, I can support that recovery too. See the My Approach tab for how I work.

How Long For A Finger Tendon Rupture To Heal?

There is little doubt that having an injured hand makes everyday life more difficult. Your ability to do simple tasks like driving, cleaning or writing could be affected. Individual recovery times vary. It can take up to 12 weeks after surgery before you start using your hand tendons again (NHS, 2025), and a repaired flexor tendon takes around 3 to 4 months to heal before the hand is strong enough to use without restrictions (American Academy of Orthopaedic Surgeons, n.d.). Stiffness after surgery is common but usually responds to therapy (American Academy of Orthopaedic Surgeons, n.d.). After a very bad injury, the tendons may be weaker and have less range of movement than before (NHS, 2025).
