2. Ankle Anatomy Flashcards
Lateral ankle ligaments
May be injured with excessive inversion; Ant/Post Tibfib; Ant/Post TaloFib; Calcaneofib
Medial ankle ligaments
May be injured with excessive eversion; Deltoid ligaments
Peroneal Tendons
Inversion and eversion injuries possible; Peroneal longus - inserts at great toe; Peroneal brevis - inserts at base of 5th MT
Medial ankle muscles/tendons
Posterior tibialis; Flexor digitorum
Anterior ankle muscles/tendons
Anterior tibialis; Extensor digitorum; Extensor hallucis
Anterior tibialis
Inserts into 1st cunieform & 1st MT
Achille’s Tendon
Insertion of Gastronemius & Soleus
Ankle bursa
Retrocalcaneal; Retro-Achille’s; Subcalcaneal
Plantar Fascia
Band of fascia from calcaneus to heads of MT; inelastic; tight with high arch
Gastrocnemius
Plantar flexion with knee extended; Origin at femur; Insertion at Achille’s tendon
Soleus
Plantar flexion with knee flexed; Origin at tibia; Insertion at Achille’s tendon
Posterior Tibialis Tendon
Assists with plantarflexion; cannot be directly palpated; Located medial, posterior ankle; Inversion
Dorsiflexor muscles
Anterior tibialis; Extensor digitorum; Extensor hallucis
Plantarflexion muscles
Gastrocnemius; Soleus; Posterior tibialis
Inversion muscles
Anterior tibialis; Posterior tibialis
