Extensor Hallucis Longus: Pain Pattern and Treatment
The extensor hallucis longus is the narrow muscle between the tibialis anterior and the toe extensors, running down the front of the shin to the tip of the big toe. It lifts the big toe and helps lift the foot. Its documented pattern is pain on the top of the foot at the base of the big toe, spreading into the toe, with a short spill up the front of the ankle.
Attachments and action
Origin: The middle half of the front of the fibula and the interosseous membrane.
Insertion: The base of the distal phalanx of the big toe.
Action: Extension of the big toe; assists dorsiflexion and inversion of the foot.
Where the pain is felt: The top of the foot at the base of the big toe. Into the big toe. A short way up the front of the ankle.
Common causes: Tight laces or a shoe that presses the top of the foot at the big toe; walking uphill; a long drive; kicking; a stubbed big toe that healed with the toe held up.
Patients say: "The top of my foot at my big toe aches in shoes." "My big toe hurts on top, not underneath." Pain lifting the toes to clear a step.
When to get evaluated: Big-toe pain with redness, heat, and swelling that arrives overnight needs gout assessed. Pain on the top of the foot with swelling after a sudden increase in activity needs a stress fracture ruled out. A big toe that will not lift with weakness lifting the foot needs the nerve assessed.
How this muscle is examined and treated
Examination tests big-toe extension against resistance, checks the joint at the base of the toe, and presses the front of the shin between the tibialis anterior and the toe extensors for the point that reproduces the pain. Needling here addresses the muscle on the front of the shin. Assessment and treatment happen in the same visit.
