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
