Q

Medial transverse tarsal ligaments

Study These Flashcards
A

Dorsal talonavicular ligament
Spring ligament

24
Spring ligament is also known as...
Plantar calcaneonavicular ligament
25
Lateral transverse tarsal joint is also known as
Calcaneocuboid joint
26
What type of joint is the Calcaneocuboid joint
Plane synovial
27
What are the 3 lateral transverse tarsal ligaments
Dorsal calcaneocuboid ligament Long plantar ligament Short plantar ligament
28
Tarsometatarsal joint is also called
Lisfranc joint
29
The cuneiforms articulate with
Metatarsals 1,2,3
30
The cuboid articulates with
Metatarsals 4,5
31
What type of joint is the tarsometatarsal joint
Plane synovial joint
32
How does a lisfranc joint happen
Base of metatarsal moves anteriorly away from cuneiform
33
What type of joint are the intermetatarsal joints
Plane synovial joints
34
What type of joints are the metatarsophalangeal joints
Synovial condyloid joints
35
Metatarsophalangeal joints actions
Flexion Extension Abduction Adduction Circumlocution
36
Other name for bunions
Hallux Valgus
37
What type of joints are the interphalangeal joints
Synovial hinge joints
38
What is the function of the foot arches
Arches distribute forces around the foot
39
Weight bearing areas on the sole of the foot
Tuberosity of calcaneus Heads of 3rd to 5th metatarsals Sesamoid bones of 1st metatarsal Head of 2nd metatarsal
40
Bony components of medial longitudinal arch
Calcaneus Talus Navicular Cuneiforms Metatarsals 1-3
41
Ligamentous components of medial longitudinal arch
Long plantar ligament Short plantar ligament Spring ligament Plantar aponeurosis
42
Bony components of lateral longitudinal arch
Calcaneus Cuboid Metatarsals 4+5
43
Ligamentous components of lateral longitudinal arch
Long plantar ligament Short plantar ligament Plantar aponeurosis
44
Bony components of transverse arch
Cuneiforms Cuboid Metatarsal bases
45
What does the transverse arch do
Prevents splayfoot
46
What is pes planus
Fallen arches
47
Why does pes planus happen
Longitudinal arches collapse Talus + navicular displaced inferiorly Increased tension on spring ligament Deficient passive stabilizers (pain in calf + foot)
48
What is pes cavus
High arches
49
Why does pes cavus happen
Elevated longitudinal arches Excessive pressure placed on ball + heel of foot - likely to cause calluses (Leads to foot joint pain)
