- What it is
- The longest ligament of the sole of the foot.
- Location
- Runs from the plantar surface of the calcaneus forward to the cuboid and the bases of the middle metatarsals.
- Function
- Supports the lateral longitudinal arch and the calcaneocuboid joint.
- Body system
- Skeletal · paired (left and right)
- FMA ID
- FMA44249 (Foundational Model of Anatomy)
Key facts
- It bridges the groove for the fibularis longus tendon, forming a tunnel.
- With the plantar calcaneocuboid (short plantar) ligament deep to it and the plantar aponeurosis, it ties the lateral arch like a bowstring.
