1 ESAT 3600 Fundamentals of Athletic Training

2  Tibiofibular joint  Ankle (Talocrural) joint ◦ Distal end of tibia fibula & Talus  Subtalar joint  Divisions of foot

3  Mortise ◦ Recess or hole ◦ Lateral and medial malleolus  Tenon ◦ Peg ◦ Talus  Tenon fits into mortise

4  Tibia ◦ Medial malleolus  Fibula ◦ Lateral Malleolus

5  Talus  Calcaneus  Navicular  Cuneiform 1-3  Cuboid  Metatarsals  Phalanges

6  Sustentaculum tali  Sinus tarsi  Neck of talus  Head of talus  Body of talus

7  Distal Tibiofibular ◦ Interosseous membrane ◦ Anterior tibiofibular ligament ◦ Posterior tibiofibular ligament  Posterior ◦ Talocalcaneals  Lateral  Posterior  medial

8  Deltoid ◦ Tibionavicular ◦ Tibiocalcaneal ◦ Tibiotatalar  Calcaneonavicular ◦ Spring ligament

9  Very strong  Prevents eversion  Difficult to rupture ◦ Usually involves either avulsion fracture or spiral fracture of tibia

10  Anterior Talofibular ◦ Inversion and plantar flexion  Calcaneofibular ◦ inversion  Posterior talofibular

11  Hold tendons in place ◦ Extensor  superior  Inferior ◦ Flexor ◦ Peroneal  Superior  inferior

12  Strong bony stability  Strong ligaments

13  Talocrural ◦ Plantar flexion ◦ Dorsiflexion  Subtaler ◦ Inversion ◦ Eversion ◦ Abduction ◦ Adduction

14  Axis not truly horizontal  Tilt causes movement to not be truly in sagittal plane

15

16  Axis not truly horizontal  Arthrokinematics ◦ Sliding

17  Oblique nature of joints causes movements to occur together ◦ P-flexion with inversion and adduction  Supination ◦ D-flexion with eversion and abduction  Pronation of foot

18  Subtalar joint is main connection between mobility and stability of ankle complex  Allows adaptive movements of foot  Shape of talus contributes to stability ◦ Wedge shape  Ligaments of ankle/subtalar joint play significant role in stability

19  Transmit loads between lower leg and ground  Static  Dynamic ◦ Shock absorption ◦ Propulsion

20  AKA ◦ Mid-tarsal joint ◦ Chopart’s joint  2 articulations ◦ Talonavicular joint ◦ Calcaneocuboid joint

21  Oblique ◦ Abduction and dorsiflexion ◦ Adduction and plantarflexion  Longitudinal ◦ Eversion ◦ Inversion

22  Adds to: ◦ Pronation of foot ◦ Supination of foot  Especially on uneven and unstable surfaces

23  Shock absorber  Load-bearing structure ◦ Load distribution  Rearfoot = 60%  Midfoot = 8%  Forefoot = 28%

24  Pes Planus  Pes Cavus

25  Cuneonavicular joints  Cuboideonavicular joint  Intercuneiform joint complex  Cuneocuboid joint complex

26

27  Intermetatarsal joints  Metatarsophalangeal joints  Interphalangeal joints

28  Tibialis anterior  Extensor digitorum longus  Extensor hallucis longus  Peroneus tertius  Innervation ◦ Deep Peroneal nerve

29  Peroneus Longus  Peroneus Brevis  Innervation ◦ Superficial peroneal nerve

30  Superficial (P-Flexors) ◦ Gastrocnemius ◦ Soleus ◦ Plantaris  Deep (Invertors) ◦ Tibialis Posterior ◦ Flexor digitorum longus ◦ Flexor hallucis longus  Innervation ◦ Tibial

31

32  Layer 1 ◦ Flexor digitorum brevis ◦ Abductor hallucis ◦ Abductor digiti minimi

33  Layer 2 ◦ Quadratus plantae ◦ Lumbricals

34  Layer 3 ◦ Adductor hallucis ◦ Flexor hallucis brevis ◦ Flexor digiti minimi  Layer 4 ◦ Plantar interossei ◦ Dorsal interossei

35  O: lateral condyle of tibia, proximal 2/3 of lateral surface of tibia, interosseous membrane, deep fascia and lateral intermuscular septum  I: plantar surface of base of 1 st metatarsal and medial plantar surface of 1 st cuneiform  A: dorsiflexes and inverts foot at ankle  RO-IA: active in standing balance mechanism (A/P sway)

36  O: lateral condyle of tibia, head and proximal ¾ of anterior surface on body of fibula, proximal portion of the interosseous membrane, deep fascia and intermuscular septa  I: divides into 4 tendons, inserts on dorsal surfaces of the bases of the middle and distal phalanges of the 2 nd -5 th toes.  A: extends lateral 4 toes, dorsiflexes and everts foot at ankle

37  O: middle ½ of anterior surface of the fibula and the adjacent interosseus membrane  I: dorsal surface of base of distal phalanx of big toe  A: extends distal phalanx of big toe; extends proximal phalanx, dorsiflexes and inverts foot at ankle

38  O: distal 1/3 of anterior surface of fibula, interosseous membrane and adjacent intermuscular septum  I: dorsal surface of the base of the 5 th metatarsal  A: dorsiflexes and everts foot at the ankle

39  O: head and proximal 2/3 of lateral surface of fibula, intermuscular septa and adjacent fascia  I: lateral margin of plantar surface of 1 st cuneiform and base of 1 st metatarsal  A: eversion and plantar flexion of the foot at ankle; lateral stability to ankle

40  O: distal 2/3 of lateral surface of the body of fibula and adjacent intermuscular septa  I: tuberosity on lateral side of base of 5 th metatarsal  A: eversion and plantar flexion of foot at the ankle; lateral stability to ankle

41  O: lateral condyle and posterior surface of femur, capsule of knee joint. Medial condyle and adjacent part of femur  I: posterior surface of calcaneus by means of Achilles tendon  A: plantar flexion and inversion of foot, flexes leg at knee (especially when foot is dorsiflexed)

42  O: posterior surface of head and upper 1/3 of shaft of fibula, soleal line and middle 1/3 of medial border of tibia, tendinous arch between tibia and fibula  I: posterior surface of calcaneus by means of Achilles tendon  A: plantar flexion and inversion of foot at the ankle  RO-IA: active in standing balance mechanism (forward sway)

43  O: lower part of lateral supracondylar line of femur and from oblique popliteal ligament of knee joint  I: posterior part of calcaneus medial to Achilles tendon  A: plantar flexes and inverts foot at ankle, flexes leg at knee
