Abstract
Tendon transfer for radial nerve palsy is a common procedure done under general anesthesia. We describe a surgical technique of triple tendon transfer with wide awake local anesthesia no tourniquet (WALANT). We transfer flexor carpi radialis to extensor digitorum communis, palmaris longus to extensor pollicis longus, and pronator teres to extensor carpi radialis brevis. This is commonly known as the Brand transfer. Our anesthetic or WALANT solution consists of up to 200 mL of 1:400,000 epinephrine, 0.25% lidocaine buffered with sodium bicarbonate. This technique overcomes the problem of judging the appropriate amount of transfer tension by observing awake patients actively extend their fingers, thumb, and wrist during the surgery and making adjustments before we close the wound. In our experience, there is no need of brain retraining because a patient is able to immediately use the flexor muscles to perform extension movements. WALANT is a safe and viable option for radial nerve tendon transfers.
