1. Flashcards
Medial Ankle Ligaments
Anterior Tibiotalar
Tibionavicular
Tibiocalcaneal
Posterior tibiotalar
*Plantar Calcaneonavicular (does not cross joint)
Lateral ankle ligaments
Posterior Tibiofibular Posterior Talofibular Calcaneofibular Anterior Talofibular Anterior Tibiofibular
*smaller ligaments than medial ankle
Sprain vs Strain
Sprain = ligament
Strain = Muscle
Most commonly sprained ankle ligament?
Anterior Talofibular (inversion and plantar flexion)
Why is bruising seen on either side of ankle when inversion causes a sprain?
Anterior Talofibular Ligament Sprain
- motion causes crushed ligaments and blood vessels
Arch of the foot
long plantar ligament
ligaments on sole of the foot
long plantar ligament
plantar calcaneo-cuboid ligament (short plantar ligament)
plantar calcaneo-navicular ligament
*fibularis longus “tendon”
Ligaments across metatarsophalangeal joints and interphalangeal joints
collateral ligaments
Ligament forming the webbing of toes
deep transverse metatarsal ligaments
- between toes at proximal interphalngeal joints
Ligaments on intermetatarsal joints for tendons of long muscles to travel through
plantar ligaments
- flexor pully system
- keeps tendons in place
Fascia vs Ligament
Ligaments
- organized
- strong in one direction
Fascia
- disorganized
- strong in many directions
Saphenous Nerve origin and innervation
- branch of femoral nerve
- supplies skin of medial side of leg and foot
Tibial Nerve origin and innervation
- from sciatic nerves
- posterior compartment of leg and base of foot
Superficial Fibular Nerve origin and innervation
- common fibular nerve
- lateral compartment of leg
Deep Superficial Nerve origin and innervation
- common fibular nerve
- anterior compartment of leg
branches of sciatic nerve
tibial nerve (post. compartment) common fibular (lat. and ant. compartment)
branches of popliteal artery
anterior tibial (ant. leg)
posterior tibial
fibular
anterior tibial artery travels with?
deep fibular nerve
