Surgical Tutorial – Median to Radial Nerve Tendon Transfers: PT to ECRB, FCR to EDC, PL to EPL.
Tendon transfers are an available option for reconstructing wrist and finger/thumb extension following radial nerve injury when nerve transfers are contra-indicated. The donor median-innervated tendons are used to reconstruct the recipient radial-innervated tendons. This tutorial describes the following tendon transfers: (1) pronator teres (PT) to extensor carpi radialis brevis (ECRB), (2) flexor carpi radialis (FCR) to extensor digitorum communis (EDC), and (3) palmaris longus (PL) to extensor pollicis longus (EPL). In this specific case, the patient had a left humeral fracture and lost complete radial nerve function. He consulted with our institution six months following the injury. While he was within the time limitation of nerve transfers, he elected for tendon transfers for radial nerve palsy.
