Study These Flashcards
A

Calcaneonavicular (spring) ligament

25
The calcaneonavicular ligament goes from the ________ _______ to the _______ _______.
Sustentaculum tali | Inferior navicular
26
The calcaneonavicular ligament is continuous medially with the ________ ligament.
Deltoid
27
The calcaneonavicular ligament is continuous laterally with which ligament?
Medial band of bifurcate ligament
28
The calcaneonavicular ligament helps to maintain the _______ _______ _______.
Medial longitudinal arch
29
This joint deals with the articulating bones calcaneus and cuboid and its movements are triplanar.
Calcaneocuboid joint
30
What ligaments are involved with the calcaneocuboid joint?
``` Short plantar (plantar calcaneocuboid) Long plantar ```
31
This is the most important ligament of the calcaneocuboid joint.
Long plantar
32
This joint is a composite joint consisting of the talonavicular and calcaneocuboid joints.
Transverse tarsal joint
33
The transverse tarsal joint is the traditional link between the _______ and _______.
Hindfoot | Forefoot
34
What actions does the transverse tarsal joint perform?
Inversion | Eversion
35
The transverse tarsal joint compensates the forefoot for hindfoot (INVERSION/EVERSION).
Eversion
36
The transverse tarsal joint compensation between the hindfoot and forefoot is not possible when the hindfoot is (INVERTED/EVERTED).
Inverted
37
The transverse tarsal joint keeps the distal foot (INVERTED/EVERTED) with the lateral surface in contact with the ground while the hindfoot is everted.
Inverted
38
These are localized thickenings of the anterior crural fascia.
Superior/Inferior extensor retinacula
39
What four muscle's tendons are bound down by the superior/inferior extensor retinacula?
Tibialis anterior Extensor hallucis longus Extensor digitorum longus Peroneus tertius
40
What nerve and artery do the superior/inferior extensor retinacula cover?
``` Deep peroneal (fibular) nerve Anterior tibial artery ```
41
The inferior retinaculum is _____-shaped.
Y
42
This is a localized medial thickening of the crural fascia.
Flexor retinaculum
43
What muscle's tendons are bound down by the flexor retinaculum?
Flexor hallucis longus Flexor digitorum longus Tibial posterior
44
What nerve and artery does the flexor retinaculum cover?
Tibial nerve | Posterior tibial artery
45
This is a localized medial thickening of lateral deep fascia.
Peroneal (fibular) retinaculum
46
What muscle's tendons are bound down by the peroneal (fibular) retinaculum?
Peroneus (fibularis) longus | Peroneus (fibularis) brevis
47
The longitudinal plantar arches can be ________ or ________.
Medial | Lateral
48
Pathologies of the plantar arches are _____ _____ or "high arch" and ______ ______ or "flat feet".
Pes cavus | Pes planus
49
What is the primary support ligament for the medial longitudinal arch?
Plantar calcaneonavicular (spring) ligament
50
What is the primary support ligament for the lateral longitudinal arch?
Long plantar ligament
51
What are 3 other support ligaments of the plantar arches?
Plantar aponeurosis Plantar calcaneocuboid (short plantar) Marginal abductors
52
What are 2 other arch support structures?
Shapes of bones | Peroneus longus
53
This is the general term for the superficial fascial structures that bind tendons and muscles down against the foot to prevent excessive free movement.
Retinacula
54
This is a fascial sheath from the calcaneus that divides into 5 bands that enclose the flexor tendons going to the toes. It functions as a superficial ligament and can tighten and cause plantar fasciitis.
Plantar aponeurosis
