articulation of ankle joint
Inferior tibial surface & medial malleolus
Lateral malleolus of fibula

dorsiflexion involves what compartment of the leg AND what nerve of the leg
anterior compartment
deep peroneal nerve
plantarflexion involves what compartment of the leg AND what nerve of the leg
posterior compartment
tibial nerve
what nerve gets injured when hit at the lateral side of the leg
common peroneal nerve
damage to common peroneal nerve leads to
foot drop

name the 3 separate ligaments the lateral ligament is composed of
Calcaneofibular
Anterior talofibular
Posterior talofibular

Tom, Dick And Very Nervous Harry (from lateral to medial)
Tibialis posterior, flexor Digitorum longus, posterior tibial Artery Vein, tibial Nerve, flexor Hallicus longus.
pott’s fracture mechanism of injury
External rotation and overeversion
most commonly injured ligaments in lateral ligaments
calcaneofibular
anterior talofibular
potts fracture
fracture of one or both fibula or tibial malleolus
treatment of potts fracture
Plates, screws external fixation
pilon fracture
fracture in distal end in one or both of fibula and tibia
how many bones of the foot categorize them
26 bones
7 tarsals
5 metatarsals
14 phalanges
mnemonic for tarsal bones
Tiger Cubs Need MILC Talus Calcaneus Navicular Medial cuneiform Intermediate Cuneiform Lateral Cuneiform Cuboid
ligaments that maintain the arch of the foot
plantar aponeurosis - from calcaneus to proximal phalanges
long plantar ligament from calcaneus to
plantar calcaneonavicular ligament - calcaneus and navicular
another name for calcaneonavicular ligament
spring ligament
where specifically in the calcaneus does the spring ligament originate
anterior sustentaculum tali
type of joint is tarsal joint
synovial plane
name midtarsal joint
Talocalcaneonavicular & calcaneocuboid
movements involved in midtarsal joint
Inversion
Eversion
inversion
that sole faces medially.
eversion
that sole faces in lateral direction
muscles involved in inversion
Tibialis Ant
Ext Hal Long
Tibialis Post
muscles involved in eversion
Peroneus (long, brev, tert)
sensory supply in sole of foot
Medial plantar
Lateral plantar
medial plantar nerves supply
Cutaneous to medial three and one-half toes. The nerves extend onto dorsum and supply the nail beds and tips of the toes
lateral plantar nerves
lateral one and one half toes supply the nail beds and tips of toes.
medial plantar artery supply
Smaller – supplies medial side of big toe.
lateral plantar artery suu
pply
Larger – passes deep to flexor retinaculum, muscles of sole of foot
Forms plantar arch
At the first intermetatarsal space joins the dorsalis pedis artery
Supplies digital arteries to the toes
dorsalis pedis artery is a continuation of..
anterior tibial artery
where can the dorsalis pedis artery be palpated
proximal part of first dorsal metatarsal space b/w the tendons of EHL medially & EDL laterally
where does posterior tibial artery pass behind
medial malleolus beneath the flexor retinaculum b/w the tendons of FDL & FHL
when can the peripheral pulse felt
in popliteal fossa behind the knee when flexed
popliteal fossa lateral to medial
semimembranosus, common fibular nerve, tibial nerve popliteal vein popliteal artery, bicep femoris
