Naviculocuneiform Plantar Ligaments

ligamenta naviculocuneiformia plantaria

The plantar naviculocuneiform ligaments connect the inferior navicular to the plantar surface of the three cuneiform bones, providing the primary plantar stability of the naviculocuneiform joints.

Region: Foot & Ankle
Biomechanics

Function & Actions

Provide the primary plantar constraint of the naviculocuneiform articulations, maintain medial column plantar stability, and are the ligaments most at risk in navicular stress fractures from repetitive plantarflexion loading.

Clinical Relevance

Clinical Notes

Naviculocuneiform ligament disruption contributes to medial column instability in midfoot injuries. Navicular stress fractures involving the naviculocuneiform plantar attachments require non-weight-bearing immobilisation.

Pathology

Common Injuries & Conditions

Navicular Stress Fracture with Ligament Involvement

Navicular stress fracture disrupting the plantar naviculocuneiform ligament attachments, requiring non-weight-bearing cast immobilisation for 6-8 weeks with screw fixation for displaced fractures.
