Procedures aiming at restoring the function of a paralyzed muscle are known as tendon transfers. The technique consists in rerouting an active muscle by bringing its tendon into the tendon of a paralyzed muscle in order to restore its function. The most frequent tendon transfers in the upper limb are performed to restore active extension of the wrist. After the surgery, full immobilization of the part is required for four weeks, then physiotherapy is required, usually three times a week for two months. It is an important part of the success of this technique.
