Joints & Ligaments of the Foot & Ankle Flashcards
A joint involving the articulation between the calcaneus and the cuboid.
Calcaneocuboid Joint
What type of joint is the calcaneocuboid joint classified as?
Synovial Plane Joint
A ligament that attaches from the plantar surface of the calcaneus to the cuboid and the bases of the 2nd, 3rd, & 4th metatarsals. It forms a tunnel for the tendon of peroneus longus and helps maintain the arches of the foot.
Long Plantar Ligament
A joint between the talocalcaneonavicular joint and the calcaneocuboid joint.
Transverse Tarsal Joint (aka. Midtarsal Joint)
What 2 movements are available at the transverse tarsal joint? It also increases this range by allowing for _________ and _________ of the forefoot.
1) Inversion
2) Eversion
Abduction & Adduction
Articulations of the tarsal bones in the foot.
Intertarsal Joints
Articulations between the bases of the metatarsals and the distal surfaces of the cuneiforms and the cuboid.
Tarsometatarsal Joints
Articulations between the bases of the metatarsals.
Intermetatarsal Joints
What type of joints are the intertarsal, tarsometatarsal and intermetatarsal joints classified as?
Synovial Plane Joints
Little movement is available at the ___ tarsometatarsal joint.
2nd
The bases of the 2nd through 5th metatarsals are firmly bound by _________.
Ligaments
Articulations between the heads of the metatarsals and the bases of the proximal phalanges. The plantar surface of the joint capsules are thickened to form plantar plates.
Metatarsophalangeal Joints
What type of joints are metatarsophalangeal joints classified as?
Synovial Condyloid Joints
What are the 5 types of movement available at metatarsophalangeal joints?
1) Flexion
2) Extension
3) Abduction
4) Adduction
5) Circumduction
__________ ligaments offer support on either side of the metatarsophalangeal joints.
Collateral
Articulations between the heads of the phalanges and the bases of the distal phalanges.
Interphalangeal Joints (aka. PIPS & DIPS)
What type of joints are interphalangeal joints classified as?
Synovial Hinge Joints
What are the 2 types of movement available at interphalangeal joints?
1) Flexion
2) Extension
__________ ligaments offer support to the interphalangeal joints.
Collateral
Bones of the foot form ______, which act as shock absorbers and distribute the stresses through the bones of the foot.
Arches
What are the 3 arches of the foot?
1) Medial Longitudinal Arch
2) Lateral Longitudinal Arch
3) Transverse Arch
What are the 4 components that maintain the arches of the foot?
1) Shape of interlocking bones
2) Ligaments
3) Fascia
4) Action of the muscles
The arch of the foot that consists of the calcaneus, talus, navicular, 3 cuneiforms, and 1st through 3rd metatarsals. Does not normally come in contact with the ground and is more involved in propulsion than weight bearing.
Medial Longitudinal Arch
The arch of the foot that consists of the calcaneus, cuboid, and the 4th & 5th metatarsals. More involved in weight bearing than propulsion.
Lateral Longitudinal Arch
The arch of the foot that involves the whole length of the foot.
Transverse Arch
What are the 3 portions of the transverse arch?
1) Anterior Portion
2) Middle Portion
3) Posterior Portion
The portion of the transverse arch that runs from the head of the 1st metatarsal to the head of the 5th metatarsal.
Anterior Portion
The portion of the transverse arch that runs from the 1st cuneiform to the cuboid.
Middle Portion
The portion of the transverse arch that runs from the navicular to the cuboid.
Posterior Portion
The thick, central connective tissue on the sole of the foot that attaches between the medial calcaneal tubercle and the proximal phalanx of each toe. It is actually continuous with the fascia of the calf.
Plantar Fascia (aka. Plantar Aponeurosis)
As the toes extend (primarily the 1st), the plantar fascia tightens because it crosses the MTPs. As it tightens, it pulls the calcaneus anteriorly and elevates the arches, putting the foot into a position of supination.
Windlass Mechanism of the Foot
What process will occur with the foot whether the action is active, passive, weight-bearing or non-weight bearing?
