calcaneus
|
talar facets
sustentaculum tali calcaneal tuber peroneal (fibular) trochlea |
|
|
what are the facets of the calcaneus
|
anterior, middle, and posterior
|
|
|
the sustentaculum tali is the sulcus for what
|
the flexor hallucis longus tendon
|
|
|
calceneal tuber has
|
medial process
lateral process tuberal ridge |
|
|
the true tallus jt is where
|
dorsiflexion and plantarflexion occur
|
|
|
if you are standing on your tip of your toes you are
|
more prone to dislocation
|
|
|
other tarsals
|
navicular
cuboid 1st cuneiform 2nd cuneiform 3rd cuneiform |
|
|
navicular tarsal
|
tuberosity (tibialis posterior m.)
|
|
|
cuboid
|
has a tuberosity
|
|
|
1st cuneiform
|
is the largest
|
|
|
2nd cuneiform
|
smallest and has a tarsal on it
|
|
|
3rd cuneiform
|
makes most articulations (5, sometimes 6)
|
|
|
what is the spring ligament
|
the plantar calcaneonavicular lig
main supporting ligament for tallus w/o any attachment to tallus |
|
|
medial ankle support
|
deltoid ligament
medial ankle is very strong, injured less frequently also, fibula extends more distal to provide extensive lateral bony block for eversion |
|
|
deltoid ligament of medial ankle support
|
provides anterior tibiotalar (deep deltoid)
posterior tibiotalar lig. tibiocalcaneal lig. tibionavicular lig. |
|
|
which one of these deltoid ligaments is most often torn?
|
anterior talofibular ligament (deep deltoid)
|
|
|
lateral ankle support
|
anterior talofibular ligament
-most frequently torn ligament in body posterior talofibular ligament |
|
|
metatarsals
|
heads are distal,bases proximal
2nd- longest metatarsal 1st- tuberosity (peroneus longus m attaches) 3rd- tuberosity (peroneus brevis m. attaches) |
|
|
intrinsic pedal muscles (20)
|
dorsum
tendons of |
|
|
dorsum (top)
|
2
extensor digitorum brevis m. extensor hallucis brevis m. |
|
|
tendons of intrinsic pedal muscles include
|
tendons of:
tibialis anterior extensor hallucis longus extensor digitorum longus peroneus tertius |
|
|
plantar surface (undersurface)
|
first (superficial) layer
|
|
|
1st (superficial) layer of plantar surface has
|
3 muscles
abductor hallucis m. flexor digitorum brevis m. abductor digiti minimi m. |
|
|
abductor hallucis m.
|
porta pedis = doorway to foot for neurovascular passage (tibial n., posterior tibial a., tendons)
|
|
|
plantar surface
|
neurovascular plane is between first and second layers of the foot
|
|
|
which n. is like the ulnar n. and why
|
the lateral plantar n. because it supplies 14 mm.
|
|
|
the 2nd layer of plantar surface (5)
|
quadratus plantae m. aka flexor digitorum acessorius m. (unlike any m. in hand)
lumbrical mm. (4) |
|
|
where does the lumbrical mm. originate?
|
from the flexor digitorum longus tendon
|
|
|
the 2nd layer of plantar surface also has tendons of
|
flexor digitorum longus and flexor hallucis longus m.
FDL (dick) crosses superficially to FHL (harry) |
|
|
3rd layer (3)
|
flexor hallucis brevis m.
adductor hallucis m. -transverse head -oblique head flexor digiti minimi m. |
|
|
4th layer of plantar surface has
|
7 muscles
dorsal interossei mm. (4) abduct. palmar interossei mm. (3) adduct. |
|
|
4th layer of plantar surface has
|
axis of function is 2nd digit
-therefore 2nd toe had 2 dorsal interossei mm. there is also the tendon of peroneus longus m. |
|
|
pedal muscle innervation
|
tibial n.
common peroneal n. |
|
|
tibial n.
|
-medial plantar n. (F2LAb) (4)
-flexor hallucis brevis -flexor digitorum brevis -lumbrical (first) -abductor hallucis -lateral plantar n. (14) |
|
|
common peroneal n.
|
deep peroneal n. (mm. on dorsum) (2)
|
|
|
manus vs. pes
|
muscles on dorsum
quadratus plantae m. opponens mm. # of arterial arches plantar/tarsal arches axis of ab/adduction 3rd hand and 2nd foot lumbrical innervation # of carpals/tarsals (carpus v. tarsus) |
