The WDFHO enables persons with tetraplegic SCI to attain a functional tenodesis grasp that creates enough passive tension in the paralyzed thumb and finger flexor muscles (such as flexor pollicis longus, flexor digitorum superficialis, and flexor digitorum profundus) with active wrist extension by contraction of the innervated extensor carpi radialis brevis (ECRB) and extensor carpi radialis longus (ECRL).
It bifurcates at the level of the elbow joint into the superficial nerve, which courses dorsally under the extensor carpi radialis brevis, and the PIN, which dives under the superficial head of the supinator muscle and continues along with the posterior interosseous artery to supply all of deeper lying extensor muscles.
This is due to the relative preservation of the extensor carpi radialis longus (ECRL) along with a non-functional extensor carpi ulnaris (ECU) that is dynamically not balancing the action of the functioning ECRL and extensor carpi radialis brevis (ECRB) muscles.
