  • BONES OF THE ANKLE JOINT

  • Talocrural joint Composed of:Lateral Malleolus (Distal Portion of Fibula)Medial Malleolus (Distal portion of Tibia)Talus

  • Talocrural joint cont.JOINT MOTIONS:

    PLANTAR FLEXION

    DORSIFLEXION

  • Subtalar JointBONESCALCANEUSTALUS

  • SUBTALAR JOINT (Cont.)JOINT MOTIONSINVERSIONEVERSION

  • Distal Tib-Fib JointNo true motionLigaments prevent the tibia and fibula from spreading apart.

  • Muscles of the Foot, Ankle, Lower Leg

  • Gastrocnemius OriginMedial head medial femoral condyle;Lateral head lateral condyleInsertion the Achilles tendon, inserting on the middle 1/3 of the posterior calcaneal surfaceAction Powerful plantar flexor of ankleInnervationTibial nerve (S1, S2)

  • Soleus Origin fibular head, Insertion Achilles tendon, inserting on the middle 1/3 of the posterior calcaneal surfaceAction Powerful plantar flexor of ankleInnervation Tibial nerve (S1, S2)

  • Plantaris Origin supracondylar line of distal femurInsertion Middle 1/3 of the posterior calcaneal surface, just medial to Achilles tendonAction Plantar flexor of ankle; also flexes kneeInnervation Tibial nerve (L5, S1, S2)

  • Achilles Tendon

  • Tibialis Posterior Origin medial fibula, Insertion 2superficial slip inserts on the tuberosity of the navicular bone; deeper slip plantar sufraces of metatarsals 2 - 4 and second cuneiformAction Principal invertor of footInnervation Tibial nerve (L4, L5)

  • Flexor Digitorum Longus Origin Posterior surface of tibia Insertion Splits into four slips these slips then insert on plantar surface of bases of 2nd - 5th distal phalangesAction Flexes toes 2 - 5; also helps inversion of ankleInnervation Tibial nerve

  • Flexor Hallucis Longus Origin Inferior 2/3 of posterior surface of fibula, Insertion Plantar surface of base of distal phalanx of great toe Action Flexes great toe, helps to invert ankleInnervation Tibial nerve

  • Tibialis Anterior Origin Lateral condyle of tibia, Insertion 1st cuneiform and on base of first metatarsal Action Dorsiflexor of ankleInnervation Deep peroneal nerve (L4, L5, S1)

  • Extensor Hallucis Longus Origin Anterior fibula and the interosseous membrane Insertion Base and dorsal center of distal phalanx of great toeAction Extends great toe and dorsiflexes ankleInnervation Deep peroneal nerve (L4, L5, S1)

  • Origin head of fibula, Insertion Splits into 4 tendon slips each of which insert on middle and distal phalanges Action Extend toes 2 - 5 and dorsiflexes ankleInnervation Deep peroneal nerve (L4, L5, S1)Extensor Digitorum Longus

  • Peroneus Tertius Origin fibular shaft surfaceInsertion base of the fifth metatarsalAction evert the footInnervation Deep peroneal nerve

  • Peroneus Brevis Origin Inferior 2/3 of lateral fibular surface; Insertion Base of 5th metatarsal baseAction Everts foot Innervation Superficial peroneal nerve

  • Peroneus Longus Origin Head of fibula, Insertion 1st metatarsal baseAction Everts footInnervation Superficial peroneal nerve
