Proximal transverse arch of foot
Arcus transversus proximalis pedis
- Latin synonym: Arcus transveralis proximalis pedis
Definition
The proximal transverse arch of foot is positioned posteriorly in comparison to its distal (or anterior) counterpart. The arch spans across the sole in a coronal plane and is formed by the tarsal bones, including the cuboid and three cuneiforms.
The proximal transverse arch of foot is considered “incomplete” because only its lateral end makes contact with the ground, giving it a semi-dome appearance. It becomes complete when paired with the complementary half dome of the other foot.
The arch receives support from the tendon of the peroneus longus muscle, which extends from the lateral to the medial side within the sole.
