Flexor Digitorum Superficialis to Anterior Interosseous Nerve Transfer 0 Mackinnon SE1 Yee A1 May 10, 2011Disclosure: No authors have a financial interest in any of the products, devices, or drugs mentioned in this production or publication.For isolated anterior interosseous nerve palsies, the nerve to the flexor digitorum superficialis (FDS) is an available donor to innervate the anterior interosseous nerve (AIN) for transfer. The FDS and AIN branch are found branching from the median nerve within the same upper-middle forearm region. The nerve to the FDS branches from the median nerve on its ulnar aspect while the AIN branches from the median nerve on its radial aspect. Prior to the nerve transfer, the median nerve is decompressed and exposed by step-lengthening the superficial head of pronator teres, releasing the deep head of pronator teres, and releasing the proximal tendinous arch of FDS. The FDS to AIN nerve transfer is an available option to restore AIN function.Keywords: hand functionmedian nerveanterior interosseous nerveflexor digitorum superficialisnerve transfernerve injury Standard Edition Table of Contents- Slow down- Frustration00:00:00 - Introduction00:00:10 - Orientation00:00:15 - Incision / Exposure00:00:41 - Identification of the Branch of the Lateral Antebrachial Cutaneous Nerve00:01:05 - Identifying and Exposing the Brachioradialis00:01:35 - Identifying the Plane between Brachioradialis and Pronator Teres00:02:00 - Step-lengthening the Superficial Head of the Pronator Teres00:02:48 - Identification of the Median Nerve in the Proximal Forearm00:03:00 - Transecting the Deep Head of the Pronator Teres00:03:20 - Release the Arch of the Proximal Flexor Digitorum Superficialis00:03:29 - Identifying and Electrical Stimulating the Donor Flexor Digitorum Superficialis Nerve Branch00:03:39 - Identifying and Electrical Stimulating the Recipient Anterior Interosseous Nerve Branch00:04:48 - Distal Transection of the Donor Flexor Digitorum Superficialis Nerve Branch00:05:14 - Proximal Transection of the Recipient Anterior Interosseous Nerve Branch00:05:23 - Flexor Digitorum Superficialis to Anterior Interosseous Nerve Transfer You must login to view the full article and extended video on this page.
