Reading list
  • Ch68 Long toe extensor muscles
  • Neuman
  • MMT

Origin

  • Fibula (middle third of the medial surface)
  • IO membrane

Insertion

  • 1st toe (at the dorsal aponeurosis at the base of its distal phalanx)

Nerve

Deep Fibular N. (L4, L5)

Action

  • TCJ: DF
  • STJ: INV or EV (depending on initial position of foot)
  • 1st toe MTP and IP: Extension

MMT

“The EHL and the EHB muscles produce the motion of extension of the IP and MTP joints. The foot is maintained in midposition. Resistance is applied to the posterior aspect of both phalanges of the first digit into toe flexion.”
