Tendons connect muscles to bone. The fingers have tendons that run all the way up to the finger tips. The tendons on the palm side let you curl your fingers. A flexor tendon injury is damage to these tendons. When the tendons are damaged, you can lose your ability to bend your finger(s).

Flexor tendon injuries are typically caused by accidental injuries. There are no known prevention guidelines for this injury.
