What is the innervation of hte foot?

Dorsal foot

  1. superfical fibular 
  2. deep fibular - anterior leg of foot and all muscles of dorsum of foot

Medial Plantar (L.A.F.F)

all the rest of the muscles

8

Babinski sign

deep tendon reflex

flexion of toes is normal response after 4 years old

abdnormal= spreading of toes (this is normal under the age of 4)

9

What are the arteies of the foot?

from anterior al tibial 

  • dorsalis pedius a 
    • sole of foot deep plantar
    • across metatarsals 2-5 arcuate a 

 

sole of foot

from posterial tibial a 

  • medial plantar a 
  • deep plantar arch  latearal plantar 
    • joined by deep plantar a from dorsum of foot

dorsum foot muscles

extensor digigtorum brevis calcaneous--> extensory expansion  (2-4) 

extensor halicous brevis calcanous--> proximal phalenex 

 

extend toes/ big toe 

deep fibular nerve

11

plantar aponeourissi

  • protects the sole of the foot
  • supports longitudinal arches
  • attaches proximal phalex--> calcaneous
  • has 5 bands that attach to digits

what is plantar fasciitis

  • most common hindfoot problem in runners
  • straning and inflammation of plantar aponeurosisi
  • hurts to walk after sleeping all night 
  • can be acute or chronic
