There are 4 muscles that make up the anterior compartment of the leg:
Muscle | Origin | Insertion | Innervation | Action |
---|---|---|---|---|
Extensor digitorum longus | Lateral condyle of Tibia Fibular head and medial surface IO membrane |
Dorsal aponeurosis of 2-5th distal phalanges | Deep Fibular n. L4 - L5 |
TCJ: DF STJ: INV or EV (position dependent) 2nd-5th Toe: MTP Extension, PIP Extension, DIP Extension |
Extensor Hallucis Longus | Fibula (middle 1/3 of medial surface) IO membrane |
Dorsal aponeurosis of 1st distal phalanx | Deep Fibular n. L4 - L5 |
TCJ: DF STJ: Inversion 1st Toe: MTP Extension, IP Extension |
Fibularis tertius | Anterior border of Distal Fibula | Shaft or Base of 5th MT | Deep Fibular n. L4 - L5 |
TCJ: DF STJ: Eversion |
Tibialis Anterior | Tibia (Upper 2/3 of lateral surface) IO membrane Superficial crural fascia |
Medial cuneiform (Medial & plantar surface) 1st Metatarsal (medial base) |
