Joints of the foot Flashcards
The head of the Fibula articulates with the lateral condyle of the tibia
The Proximal Tibiofibular Joint
What type of joint and available movements is the Proximal Tibiofibular Joint
- synovial plane
- limited superior and posterior glide occurs with dorsiflexion
- limited inferior and anterior glide occurs with plantar flexion
Ligaments of the Proximal Tibiofibular Joint and attachment points
Anterior Ligament of fibular head: attaches on the anterior proximal tibia to the anterior proximal fibular
Posterior Ligament of the fibular head: attaches on the posterior proximal tibia to the posterior proximal fibula
Strong connective tissue between the tibia and the fibula and what type of joint is it
Interosseous Membrane
fibrous joint: syndesmosis
The distal end of the fibula articulates with the distal end of the tibia
The Distal Tibiofibular Joint
What type of joint is the Distal Tibiofibular Joint?
Fibrous Joint
Ligaments of the Distal Tibiofibular Joint
Interosseous ligament
anterior tibiofibular ligament
posterior tibiofibular ligament
a thickening of the interosseous membrane at its distal end
interosseous ligament
attaches: anterior distal tibia to anterior distal fibula
anterior tibiofibular ligament
attaches: posterior distal tibia to posterior distal fibula
posterior tibiofibular ligament
The distal ends of the tibia and fibula articulate with the trochlea(dome) of the talus and is a hinge joint
The talocrural Joint
Available movements of the talocrural joint
Dorsiflexion, Plantarflexion
note: during dorsiflexion, the talus forces the tibia and fibula apart which affects the proximal and distal tibiofibular joints
Ligaments of the Talocrural Joint
Deltoid Ligament, anterior talofibular ligament, calcaneofibular ligament
What are the four ligaments of the Deltoid Ligament?
Anterior Tibiotalar, posterior tibiotalar, tibionavicular, tibiocalcaneal
attaches: medial malleolus to the tarsal bones of the medial foot
deltoid ligament
checks: for eversion of the ankle
deltoid ligament
checks: for inversion (especially when the ankle is plantar flexed
anterior talofibular ligament (ATFL)
attaches: lateral malleolus to the neck of the talus
palpated through the sinus tarsi
most commonly injured ligament in the foot
anterior talofibular ligament (ATFL)
attaches: lateral malleolus to the lateral calcaneus
checks: inversion (when the ankle is in neutral)
calcaneofibular ligament
Bursaes of the Talocrural Joint
Subcutaneous calcaneal (aka retrocalcaneal) Subtendinous calcaneal
bursa between the achilles tendon and the overlying skin?
Subcutaneous calcaneal
bursa between the achilles tendon and the calcaneus?
Subtendinous calcaneal
The Intertarsal Joints are?
Subtalar, talocalcaneonavicular joint, calcaneocuboid
The inferior aspect of the talus articulates with the superior aspect of the calcaneus
synovial plane joint; checks for inversion and eversion
subtalar joint
The articulation between the talus, the calcaneus, and the navicular
synovial ball and socket joint
talocalcaneonavicular joint
a.k.a spring ligament
plantar calcaneonavicular ligament
ligament that attaches: sustentaculum tali to the the posteroinferior surface of the naivular and helps maintain the medial longitudinal arch
plantar calcaneonavicular ligament
if the plantar calcaneonavicular ligament is stretches, what happens to the head of the talus?
sinks resulting in flat foot(pes planus)
synovial plane joint that articulates between the calcaneus and the cuboid
The calcaneocuboid Joint
ligament of the Calcaneocuboid Joint; forms a tunnel for the peroneus longus tendon
long plantar ligament
Ligament that attaches: plantar surface of the calcaneus to the cuboid and the bases of the 2nd, 3rd, 4th MTs; helps maintaint the arches of the foot
long plantar ligament
aka midtarsal joint
The transverse Tarsal Joint
the talocalcaneonavicular joint and the calcaneocuboid joint are referred to as the?
Tranverse tarsal or midtarsal joint
joint that helps to increase the inversion/eversion range by allowing abduction and adduction of the forefoot
The transverse tarsal joint
distal 4 tarsal bones articulate with the bases of the metatarsal joints; plane joint; limited movement
the tarsometatarsal joints
Ligaments associated with the tarsometatarsal and the intermetatarsal joints are?
dorsal, plantar, and interosseous ligaments
bases of the metatarsals; plane joint; limited movement
intermetatarsal joints
what joint has the bases of the 2nd through the 5th metatarsals firmly bound by dorsal, plantar, and interosseous ligaments
intermetatarsal joints
the heads of the metatarsal articulates with the bases of the proximal phalanges; condyloid joint; available movements are flexion, extension, some abduction, adduction, circumduction
The Metatarsophalangeal Joint (MTP)
Joint that has collateral ligaments on either side of the joints; the plantar surface of the joint capsules are thickened to form the plantar plate (ligaments)
Metatarsophalangeal Joint
The head of one phalanx articulates with the base of the phalanx distal to it; synovial hinge; movements flexion and extension, has collateral ligaments
The Proximal and Distal Interphalangeal Joints
