Tendon transfer surgery
Tendons are the extensions of muscles in the forearms. Muscles pull on the tendons to move joints in the hand and wrist. For different reasons, a muscle or a group of muscles may have lost their ability to contract resulting in loss of active movement.
In selected cases, attaching a tendon connected to a functioning muscle to a tendon of a muscle that doesn’t work, can restore function. This procedure is called a tendon transfer.
Of course, only muscles and tendons that have an “expendable” function will be used to restore another.
