- Origin:
- middle 1/2 of the anterior surface of the fibula and adjacent interosseus membrane.
- the EHL lies dorsal to the EHB and is prevented from subluxation by the dorsal extensor hood;
- Insertion:
- dorsal surface of base of distal phalanx of hallux
- Nerve supply:
- deep peroneal , L5 > L4 , S1 ; (See Innervation )
- Action:
- extends distal phalanx of the great toe. continued action extends proximal phalanx and dorsiflexes and supinates the foot at the ankle.
- synergist: Extensor Hallucis Brevis
Extensor hallucis longus transfer for hallux varus deformity.
