Answer 3

calcaneus
sustentaculum tali
flexor retinaculum

Question 4

“thoroughpin” is the tenosynovitis of what structure?

Answer 4

fluid distension within tarsal sheath of DDF tendons

Question 5

what tendons run through the DDF sheath?

Answer 5

Lateral and caudal tibial heads of the DDFT

Question 6

what does “curb” refer to?

Answer 6

soft tissue swelling of the plantar aspect of the tarsus

Question 7

the long plantar ligament is attached where?

Answer 7

plantarolateral calcaneus to T4 and head of MT4

Question 8

what is the role of the collateral ligaments and their general attachments

Answer 8

lateral and medial collateral attach at malleoli of tibia and tarsal and MT bones

support tarsus

Question 9

describe the tendons and ligaments found coursing down the plantar aspects of the metatarsus

Answer 9

Suspensory ligament - support plantar fetlock, suspensory apparatus

Check ligament - acts as a break on DDFT, passive stay apparatus

Long plantar l.

Answer 10

SDFT - small drop of fetlock

DDFT - sole of foot is raised off ground

Suspensory - fetlock will hit ground
