Foot And Ankle Flashcards
What ligaments stabilize the distal fibs fibular joint? (3 main)
Anterior inferior tibiofibular lig.
Posterior inferior tibiofibular lig.
Interosseous membrane
What motion occurs at the Talocrural joint? (Tibiotalor joint)
Flexion extension
Subtalar joint (calcaneus talus) what motion happens here?
Inversion / eversion
What stabilizes the medial ankle ?
Medial malleolus
Deltoid ligament
What 3 main lig. Stabilize the lateral ankle?
Anterior talofibular lig.
Posterior talofibular lig.
Calcaneofibular lig.
What is more common; lateral or medial ankle Spain?
Lateral
-lateral malleolus protects ankle from eversion, less stretch of medial ligaments
What motion occurs at mid foot joint line?
Adduction/abduction
Difference between pes Planus and over pronation of foot
Vs
Difference in pes cavus and over supination of the foot?
Pes planus = flattening of the arch - Achilles’ tendon not affected
Pronation = walking on internal aspect of foot, do to bending at sub Talar joint
-Achilles will bend away From center line
Pes cavus = large arch in foot due to tight spring ligament and others
Achilles would be straight
Supination = walking on outside of foot
Achilles would bend towards medial
Observation for ankle foot (5 things) ?
1) General survey
2) Postural observation
- pes planus
- pes cavus
- Genu varus/valgus
- atrophy
- attitude
3) Shoes
- change to wear patterns
4) Gait
5) area specific
- swelling bruising, oedema, pitting, callus, blister bites, nail abnormalities, hammer toe, mallet toe, claw toe,
What are trophic changes + what are examples in the feet?
Changes resulting from interruption of nerve supply
- abnormalities of skin, hair, nails, subcutaneous tissue, bone, peripheral nerve lesion
- can result in a decrease blood supply to are = more damage
Ankle/foot Range of motion: (Talocurual motion) (Subtalar motion) (Midtarsal motion) \+ toes
Talocrural
- dorsiflexion: 20*
- Plantar Flexion: 50*
Subtalar:
- inversion 5*
- eversion 5*
Midtarsal:
-forefoot adduction 20*
Forefoot abduction 10*
Toes
-abduction/adduction, dorsiflexion/plantarflexion
Static bony palpation of foot/ankle?
Medial: -first metatarsophalengeal joint -first cuneiform -navicular tubercle -head of talus -medial malleolus Lateral: -firth metatarsalphalngeal joint -styloid process of fifth metatarsal -cuboid -calcaneus -sinus tarsi area -dome of talus -lateral malleolus Hind foot + plantar surface -dome of calcaneus -sesamoid bones -metatarsal heads
Soft tissue palpation ankle/foot?
Head of first metatarsal bone
-for swelling, redness (bunion)
Medically over talar head:
- spring lig and tibialis posterior
- callous formation with prominent talus in pes planus
Medial malleolus region:
- deltoid ligament
- tibialis posterior
- flexor digitorum longus tendon
- posterior tibial artery
- flexor hallucinate longus tendon
Dorsum of foot
- Tibialis anterior
- extensor hallucinate longus
- dorsal pedal artery
- Extensor digitorum longus
Lateral malleolus region
- anterior talofibular ligament
- extensor digitorum brevis muscle
- calcaneofibular ligament
- posterior talofibular ligament
- peroneus longus and brevis tendon
Calcaneus region
- Achilles tendon
- retrocalcaneal bursa + calcaneus bursa
Plantar surface
- heel spur
- Plantar fascia
- Morton’s neuroma
Joint play of foot?
- P-A/A-P glide tibiotalar joint
- Inversion/eversion Subtalar joint
- Dorsal-plantar/ plantar-dorsal movement of remaking small joints (individual tarsal bones (navicular, cuboid, cuniforms)
- Sheering of the metatarsal joints
