Anatomy of Movement- leg, ankle, and foot Flashcards

Distal tibiofibular Joint

Between the distal tibia and fibula

Talocrural Joint

Between the talus and distal tibia and fibula (medial/lateral malleolus)

Subtalar Joint

Between the talus and calcaneus

Metatarsophalangeal Joint

Between the metatarsal heads and the proximal phalanges

Proximal interphalangeal joints

Between the proximal and middle phalanges

Distal interphalangeal joints

Between the middle and distal ohalanges

Medial ligaments

1. Deltoid ligament
2. spring (plantar calcaneonavicular) ligament

Deltoid ligament

There are 4 parts All attach at the tibia can
be palpated eversion injury

Spring ligament

Joins the calcaneus to the navicular bone helps
support the medial arch

Lateral Ligaments

1. Anterior talofibular ligament (ATFL)
2. Calcaneofibular ligament (CFL)
3. Posterior talofibular ligament (DTFL)
*Inversion sprang/plantar flexion injury
*the names indicate the bones involved

Anterior talofibular ligament (ATFL)

Consist of:
Talus and fibula

Calcaneofibular ligament (CFL)

Consist of:
Calcaneous and Fibula

Posterior talofibular ligament (DTFL)

Consist of:
Talus and fibula

Plantar Ligaments

Plantar Fascia/ Aponeurosis
*from the calcaneus and divides into 5 bands for the digits
*The central and thicker portion is referred to as the APONEUROSIS

Arches of the foot

1. Medial Longitudinal Arch
2. Lateral Longitudinal Arch
3.Transverse Arch

Medial Longitudinal Arch

Along the medial aspect of the foot the more common
arch of the foot

Lateral Longitudinal Arch

Along the lateral aspect of the foot

Transerve Arch

Two of the most common transverse arches are across the (a)
cuboid and cuneiforms (b) five metatarsals heads

Medial Longitudinal Arch- Pes Planus

commonly called the fallen arch/ flat
foot results is excessive pronation joint
surfaces are "loose" Not able to provide the
rigid lever to toe off

Medial Longitudinal Arch- Pes Cavus

commonly called high arch results in
excessive supination joint surfaces are rigid
unable to accommodate to the variations in the ground

Gait phases: Swing phase


Stance phase


Double Stance phase
