Plantar Calcaneonavicular Ligament[edit | edit source]

Plantar Calcaneonavicular Ligament (also known as Spring Ligament)

The Plantar Calcaneonavicular Ligament (also known as the Spring Ligament) is a complex ligamentous structure located in the foot. It plays a crucial role in supporting the head of the talus and maintaining the medial longitudinal arch of the foot.

Anatomy[edit | edit source]

The Plantar Calcaneonavicular Ligament is composed of three distinct components: the superomedial, medioplantar oblique, and inferoplantar longitudinal parts. It originates from the anterior part of the sustentaculum tali of the calcaneus and inserts into the plantar surface of the navicular and the medial cuneiform.

Function[edit | edit source]

The primary function of the Plantar Calcaneonavicular Ligament is to support the head of the talus and help maintain the medial longitudinal arch of the foot. This ligament also serves as a fulcrum for the posterior tibial tendon, facilitating foot inversion.

Clinical Significance[edit | edit source]

Damage or degeneration of the Plantar Calcaneonavicular Ligament can lead to adult-acquired flatfoot deformity, a condition characterized by the collapse of the medial longitudinal arch and hindfoot valgus. This condition can cause significant pain and disability.
