Flashcards in Foot Deck (30):
where is the attachment of the superior extensor retinaculum?
anterior border of fib and tib
Inferior band of extensor retinaculum is Y-shaped. Where are the three attachments?
plantar aponeurosis medially
superolateral calcaneus laterally
Which muscles does the fibular retinaculum hold down
Fibularis longus and brevis
Which fibular retinaculum blends with the extensor retinaculum?
the inferior band, blending with the inferior extensor retinaculum
Which pneumonic is used for the flexor retinaculum?
Tom, Dick and Very Naughty Harry
What are the two key ligaments stabilising the arch of the foot?
spring and plantar ligaments
What is a leg muscle that helps to maintain the arch of the foot?
What is the name of the intrinsic muscle on the dorsum of the foot?
extensor digitorum brevis
What is the course of EDB?
arising laterally from the calcaneus, inserting into the tendons of the longus muscles on digits 1-4
What shape is the extensor hood?
triangular, with apex pointing to the tip of the toe
Which nerve gives all the motor supply for the dorsum of the foot?
deep fibular nerve
What is the sensory supply done by deep fibular nerve at the foot dorsum?
first webspace between the first and second toes
Describe the course of the dorsalis pedis artery
travels medially and give an arcuate brach that heads laterally. The main branch continues down the big toe, giving a perforating branch to the plantar surface
What muscles can be found immediately deep to the plantar neurosis?
Abductors on either side (halluces and minimi)
Flexor digitorum brevis
What are the long muscles lying immediately deep to flexor digitorum brevis
Which muscle has lumbricals associated?
Where does the FDB insert?
on either side of the base of middle phalanx
T/F lumbricals arise on the lateral sides of the FDL
False, they arise on the medial side
where does the quadratus plantae muscle insert?
the lateral border of FDL when it is breaking into four tendons
What is the action of quadratus plantae?
optimising the function of FDL by straightening the line of FDL
What muscles can be found on the 3rd layer of the sole of foot
short flexor for the big and little toe
What muscles can be found on the 4th layer of the sole of foot?
interosseous muscles between toes in the inter-metatarsal spaces
Where is the reference plane for toe abduction/adduction?
the second digit
What is the function of interosseous muscle?
adduction towards the second toe
Which layers can the neurovascular plane be found?
between the first and second layers
Which artery can be found in the plantar surface?
posterior tibial artery, splitting into medial and lateral branches
Which branch of the posterior tibial artery forms the plantar arch?
Which nerve supplies the plantar surface of foot?
tibial nerve, splitting into lateral and medial plantar nerves
What does the lateral plantar nerve supply?
lateral 1.5 toes and all intrinsic muscles
