Dorsal cuneonavicular ligaments

Dorsal cuneonavicular ligaments are a group of ligaments located in the foot. These ligaments play a crucial role in stabilizing the cuneiform bones and the navicular bone, which are part of the tarsal bones in the foot.

Anatomy

The dorsal cuneonavicular ligaments consist of three distinct ligaments:

• The medial dorsal cuneonavicular ligament
• The intermediate dorsal cuneonavicular ligament
• The lateral dorsal cuneonavicular ligament

These ligaments connect the navicular bone to the medial cuneiform, intermediate cuneiform, and lateral cuneiform bones, respectively. They are located on the dorsal (top) side of the foot.

Function

The primary function of the dorsal cuneonavicular ligaments is to provide stability to the midfoot region. They help maintain the alignment of the tarsal bones and support the arch of the foot. This stability is essential for proper gait and weight distribution during activities such as walking and running.

Clinical Significance

Injuries to the dorsal cuneonavicular ligaments can result from trauma, such as a sprain or fracture. These injuries can lead to pain, swelling, and instability in the midfoot region. Proper diagnosis and treatment are essential to prevent long-term complications.

• Plantar cuneonavicular ligaments
• Interosseous cuneonavicular ligaments
