Left Long Plantar Ligament (Ligamentum plantare longum sinister)
Educational content only — not medical advice.
Anatomy
The left long plantar ligament is the longest and most substantial tarsal ligament of the plantar foot. Originating from the plantar surface of the calcaneus anterior to the tuberosity, its fibers extend forward to insert into the tuberosity of the cuboid and the bases of the 2nd through 4th metatarsal bones. It bridges the sulcus for the fibularis longus tendon, converting it into a tunnel and bracing the lateral longitudinal arch.
Clinical notes
Provides essential passive mechanical resistance against foot flattening; chronic traction strain contributes to calcaneal spur formation and plantar midfoot arthrosis.
