25
____ is associated with injury to the interosseous talocalcaneal ligament
Sinus Tarsi syndrome
26
this ligament also lies within the tarsal sinus
cervical ligament
27
the cervical ligament attaches more
laterally from the calcaneal sulcus to inferior-lateral neck of the talus
28
cervical ligament resists
INVERSION
29
Metatarsus is the
midfoot
30
what kind of joints is the metatarsus
intertarsal joints
31
it provides
pronation and supination
32
these joints include:
subtalar | transverse tarsal joints
33
the transverse tarsal joints are the:
talocalcaneonavicular joint | calcaneocuboid joint
34
pronation and supination of the mid foot involve
rotation of the forefoot relative to the hindfoot
35
pronation and supination of the subtalar involves
movement of calcareous relative to the talus
36
Talocalcaneonavicular joint (TCNJ) is a
complex synovial joint
37
between the
head of the talus and the posterior navicular
38
the Calcaneocuboid joint is a
plane synovial joint between anterior calcaneus and posterior cuboid
39
this joint is the most versatile foot joints providing full supination and pronation
transverse tarsal joints
40
spring ligament is
plantar calcaneonavicular ligament
41
ligaments that reinforce the transverse tarsal joints are:
talonavicular lig (dorsum) bifurcate ligament MCL plantar calcaneonavicular lig
42
which is the most important ligamentous support for the TCNJ
plantar calcaneonavicular lig (spring)
43
the spring lig runs from
sustentaculum tali to the navicular tubercle
44
Calcaneocuboid joint is reinforced by
bifurcate ligament dorsal calcaneocuboid lig plantar calcaneoucuboid lig
45
the plantar ligaments of the transverse tarsal joint are:
plantar calcaneonavicular joint | plantar calcaenocuboid ligament
46
unloaded foot pronation and supination occur
summatively across both the rear foot and the midfoot
47
active supination is driven by
tibialis posterior
48
active supination arthokin
spin of the navicular about the convex talar head
49
active pronation is driven primarily by
fibularis longus
50
active pronation arthrokin
spin of the medial cuneiform about the navicular
51
Tarsometatarsl joints are
TMT | plane synovial joints
52
they are positioned
between the mid foot and forefoot
53
they allow for
limited gliding/sliding and pronation/supination
54
the joints also enable
the foot to conform to irregular surfaces
55
they are reinforced by
dorsal,plantar, and interosseous ligaments
56
which TMT joint has the greatest range of motion
1 MTM between 1st metatarsal and medial cuneiform flexion/extension some rotation
57
MTP joints are what kind of joints
condyloid synovial joints
58
the MTP provide ___ motions
plantarflexion/dorsiflexion and AB/ADuction
59
these joint primarily function to enable the foot to act
as a hinge at the toes during heel rise
60
these limit hyperextension at the IP joints
volar plates
61
the bones of the foot form
longitudinal and transverse arches
62
the arches of the foot
spread the weight of throughout the foot | act as shock absorber
63
medial longitudianl arch is composed of
``` calcaenus talus navicular 3 cuneiforms 3 medial metatarsals ```
64
the keystone is
talus
65
lateral longitudinal arch composed of
calcaneus cuboid lateral 2 metatarsals
66
transverse arch is composed of
cuboid 3 cuneiforms bases of the 5 metatarsals
67
the ______ maintains the transverse arch
wedge shape of the 2nd and 3rd cuneiforms | and base of metatarsals
68
plantar ligaments of the arches
plantar aponeurosis long plantar ligament short plantar ligament plantar calcaneonavicular ligament
69
primary ligaments supporting the arches
long plantar short plantar plantar calcaenonavicular
70
____ supports the lateral arch
fibularis longus
71
____ & _____ support the medial arch
tibialis anterior and posterior
72
Medial ligaments of the Talocural joint
posterior tibiotalar anterior tibiotalar tibiocalcaneal tibionavicular
