Foot Anatomy

Anatomy

QuestionAnswer
Ankle: Medial (deltoid) ligament Tibionavicular part; Tibiocalcaneal part; Tibiotalar part (ant and post)
Ankle: Lateral ligament Ant talofibular lig; Post talofibular lig; Calcaneofibular lig
Multiple joints contribute to: mobility of foot
Ankle joint: movement Dorsiflexion/ plantarflexion
Subtalar joint: movement Inversion/ eversion of foot
Intertarsal joints: movement Inversion/ eversion of foot
Tarsometatarsal joints: movement Limited sliding movements; Inc movement at 1st metatarsal
MTP joints: movement Flex/ ext, ltd ab/adduction, circumduction
Interphalangeal joints: movement Flexion/ extension
Arches (2) = Longitudinal; Transverse arch
Arches: fn absorb and distribute force from the body
Longitudinal arch is highest where: medially
Arches supported by ligs & tendons: Plantar aponeurosis; Long/ short plantar ligs; Tibialis ant/ post tendons; Fib longus tendon
Fascia of sole of foot wrt skin: is tightly adherent to skin
Fibrous septa: fn anchor skin and create fat-filled spaces for shock absorption
Deep fascia of foot forms: plantar aponeurosis
Ankle sprain/ fx eversion or inversion injury
Eversion injury: assoc with: medial tears of ankle (eg tibiotalar lig, Tibionavicular; Tibiocalcaneal)
Inversion injury: assoc with: lateral tears of ankle
Potts fx = aka bimalleolar fracture; shears off other malleolus
talus fx => Avascular necrosis
trimalleolar fx assoc w: ant lip of tibia (plus malleoli)
Bunion = sublux of big toe joint due to malalignment of first metatarsal (aka Hallus valgus)
Plantar fasciitis: assoc with microtears of planta fascia (can lead to calcaneal spurs)
Mallet toe injury: avulsion injury of first extensor hood to distal phalanx
Hammer & claw: imbalance of tendons of foot (e.g., wearing heels long time: shortens tendons)
Dorsum: Extrinsic mx tendons EHL; EDL
Dorsum: Intrinsic mx EHB; Ext digit brevis
Plantar: Extrinsic mx tendons FHL; FDL
Plantar: Intrinsic mx tendons Abd HB/abd digiti minimi; FDB/FHB/F digit minimi brevis; Quadratus plantae; Lumbricals; Add hall; Interossei
Foot mx: Layer 1 Abd hall; FDB; abd digit minimi
Tendon of FDL passes through: tendon of FDB (as in hand); Held to digits by fibrous digital sheaths
Foot mx: Layer 2 Tendons of extrinsic flexors (FDL, FHL); Quadratus plantae; Lumbricals
Foot: Layer 3: FHB; Adductor hallucis; Flexor digiti minimi brevis
FHB: 2 heads: origins Lateral head from cuboid; Medial head from tendon of tib post
FHB tendons contain: sesamoid bones that lie inferior to the 1st MTP joint
Adductor hallucis: Heads Oblique and transverse heads
Foot: Layer 4: Plantar interossei; Dorsal interossei
Tibial nerve splits into: Lateral plantar n.; Medial plantar n.
Blood Supply to Foot: anterior Ant tibial a. => Dorsalis pedis a. => Arcuate a. => Dorsal metatarsal arts => Dorsal digital arts
Blood Supply to Foot: posterior: Post tibial a. Post tibial a. => Lateral plantar a. => Deep plantar arch => Plantar digital arts =>
Blood Supply to Foot: posterior: Medial plantar a. Medial plantar a. => Superficial plantar arch => Plantar digital arts
Dorsum mx of foot: all innervated by: Deep fib n.
Foot mx: Layers 1-4: innervated by: tibial n.
Common fib n. gives off: Superficial fib n.; Deep fib n.
Superficial fib nerve innervates: Skin over dorsum of foot
Deep fibular nerve innervates: All mx of dorsal foot except EHB & EDB
Tibial nerve: gives off: Medial plantar n.; Lateral plantar n.
Mx of plantar foot: innervation Have split innervation btw Medial plantar n. & Lateral plantar n.
Action: Abductor hallucis Abduct great toe
Action: Flexor digitorum brevis Flex digits 2-5 at MTP and PIP joints
Action: Abductor digiti minimi Abducts fifth digit
Action: Quadratus plantae Assists FDL by attaching to FDL tendon
Action: Lumbricals Flexion of MTP joints, extension of IP joints
Action: Adductor hallucis Adduct great toe
Action: Flexor digiti minimi brevis Flex fifth digit
Action: Plantar interossei Adduct toes
Action: Dorsal interossei Abduct toes
Action: FHB Flex big toe
Dorsum: Extrinsic mx EHL; EDL
Dorsum: Intrinsic mx EHB; EDB
Plantar Foot: Extrinsic mx FHL; FDL
Plantar Foot: Intrinsic Layer 1 Abd HB; FDB; Abd dig min
Plantar Foot: Intrinsic Layer 2 tendons of FDL/FHL; quad plantae; lumbricals
Plantar Foot: Intrinsic Layer 3 FHB; Add hall; F dig min brev
Plantar Foot: Intrinsic Layer 4 PI; DI
Abd Hall: attach: Calcaneus TO prox phalanx of hallux
Abd dig min: attach: Calcaneus TO prox phalanx of 5
FDB: attach: Calcaneus TO middle phalanges of 2-5
EHL: attach: fibula TO distal of 1
EDL: attach: Tibia & fibula TO middle & distal of 2-5
EHB: attach: Calcaneus TO base of 1
EDB: attach: Calcaneus TO ext hoods of 2-4
FHB: attach: cuboid & tendon of tibialis posterior TO prox phalanx of 1
F dig min brev: attach: Base of metatarsal 5 TO Base of proximal phalanx of toe 5
Quad plantae: attach: Calcaneus TO FDL tendon
Lumbricals: attach: FDL tendon TO Extensor expansion over lateral 4 digits
Add hall: attach: Trans head: MTP joints of toes 3-5; Oblique head: base of metatarsals 2-4; TO prox phalanx of 1
PI: attach: MT 3-5 TO prox phalanges of 3-5
DI: attach: MT 1-5 TO phalanges of 2-4

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
