Plantar Fascia First Ray Attachment

aponeurosis plantaris — insertio rami primi

The first ray attachment of the plantar fascia is the medial slip that connects the central band to the sesamoid-hallux complex, providing the windlass mechanism origin for great toe push-off.

Region: Foot & Ankle
Biomechanics

Function & Actions

Provides the fascial connection between the central plantar fascia and the hallux MTP sesamoid complex — the basis of the windlass mechanism that stiffens the medial arch during push-off.

Clinical Relevance

Clinical Notes

Isolated first ray plantar fascia attachment strain produces pain specifically at the first MTP plantar-medial region rather than the heel. Hallux MTP dorsiflexion reproduces pain via the windlass mechanism. Rest and strapping are first-line management.

Common Injuries & Conditions

First Ray Plantar Fascia Attachment Sprain
