Q

Attaches to the plantar surface of the calcaneus between the tuberosity and the tubercle and distally it divides into superficial and deep fibers.

Q

What are the ligaments of the cuboideonavicular joint?>

A

Dorsal, plantar, interosseous cuboideonavicular ligament

17
Q

There are three joints between the cuneiforms and navicular. What are the ligaments between each joint?

A

Dorsal and Plantar cuneonavicular ligament

18
Q

What are the ligaments of the intercuneiform joints?

A

Dorsal, plantar, interosseous intercuneiform ligaments

19
Q

What are the ligaments of the cuneocuboid joint?

A

Dorsal, plantar, interosseous cuneocuboid ligament.

20
Q

How are the heads of the metatarsals connected to each other?

A

They don’t articulate with one another but are connected at the plantar plates by the deep transverse metatarsal ligament.

21
Q

What connects the superficial slips of the central portion of the plantar aponeurosis and helps maintain the position of fat pads at the level of the MTP’s?

A

Superficial transverse metatarsal ligament

22
Q

Attaches to the anatomical neck of the metatarsal and the edges of the base of the proximal phalanx.
It has a loose attachment to the metatarsal head which allows for dorsiflexion and plantarflexion.

A

Metatarsophalangeal capsular ligament

23
Q
  • Capsular ligament that is a fibrocartilaginous thickening of the plantar portion of the capsule
  • Attaches loosely to the head of a metatarsal and firmly to the base of a proximal phalanx.
A

Metatarsophalangeal plantar plate

24
Q

Cord-like capsular ligaments that attach to the tubercles on either side of the head of the metatarsal and the tubercles on the base of a proximal phalanx.

A

Collateral Metatarsophalangeal Ligaments

25
Q

Triangular-shaped capsular ligaments that attach to the tubercles on either side of the head of a metatarsal and the sides of the plantar plate.

A

Metatarsophalangeal suspensory ligaments

26
Q

The sesamoids divide the plantar plate of the hallux into what ligamentous regions?

A
  • Medial and lateral Metatarsosesamoid ligaments
  • Medial and lateral phalangeosesamoid ligaments
  • intersesamoid ligament
27
Q

What forms the sesamoid apparatus?

A
  • Tendon of FHB
  • Tendon of ABductor hallucis
  • Conjoined tendon of adductor hallucis
  • Sesamoids
  • Plantar plate
28
Q

What are the ligaments of the interphalangeal joints?

A

Interphalangeal capsular ligament
Interphalangeal plantar plate
2x collateral interphalangeal ligaments

29
Q

What ligaments and muscles are supported by the transverse arch?

A

Interosseous intercuneiform, cuneocuboid, tarsometatarsal, and intermetatarsal ligament

  • ADductor hallucis
  • Fibularis longus
  • plantar component of tibialis posterior
30
Q

What is the ligamentous, fibrous, and muscular support of the longitudinal arch?

A
  • Spring ligament (medial side of arch)
  • Short plantar ligament (lateral side)
  • Long plantar ligament (lateral side)
  • Central portion of plantar aponeurosis (both)
  • Tibialis posterior (medial)
