Tendon Lacerations

Tendon lacerations are injuries that occur when the tendons responsible for moving the fingers, thumb, or wrist are partially or completely cut. Tendons are strong, fibrous connective tissues that attach muscles to bones and allow the hand to perform essential functions such as gripping, pinching, and bending or straightening the fingers. Because many tendons lie just beneath the skin, even a relatively small cut to the hand or fingers can result in significant tendon damage, pain, weakness, and loss of function.

Tendon injuries are generally classified according to the location and severity of the laceration, as well as whether the tendon has been partially or completely divided. Without appropriate evaluation and treatment, a tendon laceration can lead to persistent weakness, stiffness, loss of motion, and long-term dysfunction of the affected hand or finger.
