-
three bones of the ankle joine
-
-
where are the sesmoids located
distal aspect of the first metatarsal
-
primary medial ligament
deltoid ligament
-
mechanism of a syndesmotic ankle sprain
increased external rotation or forced dorsi flextion
-
gastrocnemius
- origin: femoral condyle
- insersion: posterior aspect of calcaneus
- action: plantar flexion, weak flexion of the knee
- Nerve: tibial nerve
-
Soleus
- Origin: interoseus membrane
- Insertion:
posterior aspect of calcaneus- Action:
plantar flextion- Nerve:
tibial nerve
-
Posterior tibialis
- origin: posterior borders of tibia and fibula
- insertion:
base of 2,3,4 metatarsals. 2,3 cunieforms. cuboid- action:
plantar flexion, inversion- nerve:
tibial nerve
-
Anterior talofibular ligament
prevents anterior movement of the talus
-
calcaneofibular ligament
prevents excessive inverson of the calcaneus
-
anterior tibiofibular ligament
high angle sprain this ligament is damaged
-
interoseous membrane
- fassia
- holds bone together
- connects the tibia and fibula and runs the whole length of the leg
-
posterior talofibular ligament
prevent posterior displacement of the talus
-
deltoid ligament
resistance to eversion of the foot
-
lateral compartment
- peroneus breves
- peroneus longus
- peroneus artery
- fibula
- superficial peroneal nerve
-
superficial posterior compartment
- soleus
- gastrocnemious
- tibial nerve
-
anterior compartment
- deep peronial nerve
- extensor digitorum longus
- extensor hallucis longus
- tibialis anterior
- anterior tibial artery
-
deep posterior compartment
- tibialus posterior
- posterior tibial artery
- flexor digitorum longus
- flexto hollicus longus
-
lower leg stress syndrom: tissues damages
- anterior tibialus
- posterior tibialus
- fibula
- tibia
-
thompson test
achilles tendon
squeeze calf and see if foot moves or plantar flexes. if achilles is ruptured it wont move
-
achilles tendonitus
- greater risk of rupture
- tender to touch
-
medial longitudinal arch
- bones:
- calcaneus
- talus
- navicular
- 3 cuniforms
- 1,2,3 metatarsals
- supporting tissues:
- plantar calcaneonavicular ligament
- posterior tibialus
- plantar fassia
