The leg and foot- ligaments Flashcards
Anterior Talofibular Ligament (ATFL):
Connects the talus to the fibula in the front of the ankle.
Provides stability and is commonly injured in ankle sprains.
Calcaneofibular ligament (CFL)
Connects the calcaneus (heel bone) to the fibula.
Provides lateral support to the ankle.
Posterior talofibular ligament (PTFL)
Connects the talus to the fibula at the back of the ankle
Provides support for the ankle joint
Deltoid ligament
A strong, triangular ligament located on the medial (inner) side of the ankle.
Composed of multiple bands that connect the tibia to various tarsal bones, providing medial stability.
Short plantar ligament
Location: Runs from the calcaneus to the cuboid bone, located just deep to the long plantar ligament.
Function: Provides support to the calcaneus and assists in maintaining the stability of the lateral arch of the foot.
Long plantar ligament
Location: Extends from the calcaneus (heel bone) to the cuboid bone and the bases of the second to fifth metatarsals.
Function: Supports the longitudinal arch of the foot, helping to maintain its shape and integrity during weight-bearing activities.
Plantar fascia
Location: A thick band of connective tissue that runs along the bottom of the foot, originating from the calcaneus and extending to the bases of the proximal phalanges of the toes.
Function: Supports the medial longitudinal arch and helps absorb shock during walking and running. The plantar fascia plays a significant role in foot mechanics.
Spring Ligament (Calcaneonavicular Ligament)
Location: Connects the calcaneus to the navicular bone on the medial side of the foot.
Function: Supports the medial arch and helps maintain the relationship between the talus and the navicular bone. It plays a vital role in foot stability.
