Runs horizontally above the ankle

101
Q

Inferior extensor retinaculum

A 
Binds down the:
	TA
	EHL
	EDL
	PT
o	Y shaped band anterior to the talocrural ligaments
102
Q

Peroneal Retinacula

A

Superior and inferior peroneal retina

o Bind down the PL and PB behind the lateral malleolus

103
Q

Flexor Retinaculum

A
  • Converts the bony grooves into canals for the tendons of the TP, FDL, FHL as they pass behind the medial malleolus
  • Bridges over the posterior tibial vessels and nerves
104
Q

Synovial Sheaths at the ankle and in the foot

A
  • Double layer of synovial membrane surrounding each tendon as it passes under the retinacula
  • Facilitate sliding of the tendons
105
Q

Plantar Aponeurosis

A

• Most superficial structure of plantar surface of foot, immediately under the skin
• Triangular in shape: apex at the calcaneus, base at the heads of the metatarsals
Functions:
o binds the skin of the foot
o provides an attachment site for foot muscles
o helps to maintain arches of the foot

106
Q

Maintaining Foot Arches

Static features

A
  • shape of the bones
  • ligaments
  • plantar aponeurosis
  • long plantar ligament
  • short plantar ligament (plantar calcaneocuboid ligament)
  • spring ligament (plantar calcaneonavicular ligament)
107
Q

Maintaining Foot Arches

Dynamic features

A
  • Intrinsic foot muscles
  • Extrinsic muscles
    Longitudinal arch
  • flexor hallucis Longus
  • Flexor Digitorum Longus
    Transverse arch
  • fibularis Longus
  • tibialis Posterior
  • active and tonic contraction
108
Q

Plantar Ligaments – maintaining foot arches

A
  • Ligaments provide passive support to the arch – effective when foot is not moving (e.g. standing)
  • Long plantar ligament
  • Short plantar ligament
    o (plantar calcaneocuboid ligament)
  • Spring ligament
    o (plantar calcaneonavicular ligament)
109
Q

Maintaining foot arches - ligamentous support

A
  • Plantar aponeurosis very important
  • Thick, triangular shaped
    o Longitudinal fibres except anteriorly
    o Near metatarsal head it splits into superficial and deep layers
    o toe extension increases the tension in the aponeurosis (due to attachments)
    o This raises the longitudinal arches
     Windlass effect
     Occurs during propulsion phase of gait
  • Medial arch
  • Plantar calcaneonavicular (spring) ligament
  • All other interosseous ligaments within the medial arch
  • Lateral arch
  • Long and short plantar ligaments
110
Q

Dynamic Support of maintaining foot arches (TENDONS)

A
  • provide dynamic support to the arch – walking, running
  • tie beams or bowstrings – pull the ends of the arch together and so increase concavity
  • attach to the summit, or run under the summit and pull the summit upwards thus increasing concavity
111
Q

Digital Sweep

A
  • longest possible sweep (pathway) of the tips of the digits
  • flexion occurs at the MTP first
    o while the IP joints are maintained in extension
     flexion of the IP joints comes late
112
Q

How does digital sweep occur

A

o interplay between extrinsic & intrinsic foot muscles

o intrinsic muscles modulate the extrinsic muscles

113
Q

What is Digital Sweep?

A

o Intrinsic muscles act to extend IP joints – to avoid ‘scrunching’ up toes
o Lumbricals and interossei

114
Q

Clawing of the Toes– Loss of Intrinsic Muscle Action

A
  • means that the long flexor/FDL and long extensor/EDL work unopposed
  • multi-joint muscles tend to move their most distal joint first
    o the FDL pulls the interphalangeal joints into flexion
    o the EDL pulls the MTP joints into hyperextension
  • creates a new, abnormal position of rest
115
Q

Dorsal Digital Expansion

A

• Expansion of the extensor tendons as they approach the digits (toes)
• Functions:
o Allows all the joints of the toe to be extended simultaneously
o Provides attachment for some of the intrinsic muscles
(look at diagram on page 69 for where it is)

116
Q

Lumbricals Function (muscles)

A
  • Flex MTP joints & maintains extension of IP joints

- -> Prevents toes clawing

117

    o Medial arch (higher)
    o Lateral arch (flatter + more rigid)
  • Transverse—runs in coronal plane
    1. medial arch, lateral arch, transverse arch
134
Q

Foot arches formed and supported by

A

o Fit of the bones (congruence)
o Joint integrity
o Ligament tightness
o Muscle tension

135
Q

Transverse foot arch proximal end formed by:

A

o Metatarsal bases
o Cuboid
o All 3 cuneiform bones at proximal end

136
Q

Transverse arch distal end formed by:

A

Head of the metatarsals

137
Q

Foot Movements

A 
1. Abduction & Adduction 
o	Around long axis of leg
2. Pronation & supination 
o	Around foot’s longitudinal axis 
Foot movements:
1. Are not pure
2. Are combined
Adduction always accompanied by supination – called inversion 
Abduction always accompanied by pronation—called eversion
138
Q

Eversion

A

Dorsiflexion, abduction, pronation

139
Q

Inversion

A

Plantarflexion, adduction, supination

140
Q

Rigid vs Flexible Foot

Step- Off

A

o Plantarflex ankle & extend MTP joints
o Tightens plantar aponeurosis (windlass mechanism/ effect)
o Raises medial longitudinal arch
o Head of talus moves superiorly and subtalar joint supinates
o Mid-tarsal joint = locked
o Foot = rigid

141
Q

Rigid vs Flexible Foot

Heel strike- vice versa

A

o Subtalar joint pronates
o Mid-tarsal joint unlocks
o Foot = flexible

142
Q

Rigid vs flexible foot matter because:

A

For different stages of gait cycle:

  1. a rigid foot = efficient at propulsion
  2. a flexible foot = good at passing forces through it
    - and for keeping the foot firmly on the ground even when surfaces are not level
    - aids change of direction
143
Q

Functions of Foot arches

if feet were rigid

A

o Each step/ ground contact would generate very large forces to send through the skeleton
o The feet = flexible + ABSORB much of these shocks

144
Q

Functions of Foot Arches

Arches

A

o Absorb weight forces/ shock
o Efficient weight bearing—weight bearing areas of foot (hindfoot & forefoot)
o Add to foot’s ability to adapt to changes in ground surface contour
o Efficient propulsion – elastic recoil of arch when weight lifted off (arches flatten slightly when weight bearing)
