The impar ligament is also called which ligament?

The impar ligament is named for where it sits and what it connects—the navicular bone to the distal end toward the coffin joint on the plantar side. Because this fibrous band runs from the navicular bone to the distal phalanx, it’s the same structure referred to as the distal navicular ligament. That linkage is what gives it stability within the navicular apparatus during movement. The other options describe different ligaments (side ligaments of the navicular, a proximal connection, or a generic distal phalanx ligament) that don’t match the actual attachment and location of the impar ligament.
