Risks

Some common complications of tendon repair include infection, the tendon rupturing, and the repaired tendon sticking to nearby tissue.

Infection

An infection develops after about 1 in every 20 tendon repair operations.

Infection risk is highest if the hand is damaged and the wound is contaminated by dirt.

Crushing injuries are also more likely to cause an infection.

Symptoms that may indicate your hand has developed an infection include:

Contact your GP if you think you have developed an infection. Most infections can be successfully treated with antibiotics.

After about 1 in every 20 tendon repair operations, the repair fails and the affected tendon ruptures.

When this happens, it usually occurs soon after the operation, when the tendon is weakest.

Tendon ruptures often happen in people who don't follow the advice about resting the affected tendon.

Accidental trips, falls or suddenly catching your splint on an object can also rupture the tendon.

Sometimes, it's obvious you have ruptured the tendon because you notice a sudden snapping or "pinging" sensation in your hand.

But you may not notice the tendon has ruptured until you discover that you can't move your finger or fingers in the same way as before.

If you think your tendon has ruptured, contact your surgical team or hand therapist. Further surgery is usually required to repair the tendon.

Tendon adhesion is a medical term that means the tendons have become stuck to surrounding tissue and have lost some of their range of movement.

This can cause loss of movement, which is minor in most cases. More serious cases of tendon adhesion require surgery to free the stuck tendon.

Contact your surgical team or hand therapist if you notice a reduction in your ability to move your hand while you recover from surgery.
