3

joints of ankle and foot

intertarsal joints 

talcocrural joint (ankle) 

  • troclea of talus-->malleolar mortis 
  • ligaments
    • lateral-  anterior talofibular joint 
    • posterior- posterior talfibular joint 
    • medial - anterior/post tibiotalar
      • tbio calcaneo, tibio calcenal 

subtalar joint plane joint 

  • majorty of inversion and eversion 
  • lateral medial an dposterior talocalcaneal lig
  • interosseous tal

talonavicular ball and socket joint  joint and calcaneocuboid plane joint joint (transverse tarsal joint)

  • longg plantar lig (calcaneous--> cuboid and mt bases)
  • short plantar lig 
  • spring ling  (Talus--> sustentaculum tali) 
  • inverson eversion circumduction 

tarsaometatarsal joint 

  • plane type koint slight 

intermetatarsaljoints 

mp 

  • condyloid moints 
  • metatarsal and proximal phalanges 
  • ligaments: deep transverse metatarsal lig
  • collateral lig
  • plantar lig (plates) 

  • movements: flexion extension abduction add ductions
     

ip

  • flexion and extension 

dip 

 

4

motions ofankle

doris flexion 

anterio leg compartment , closed pack tight fit

plantar flexion posterior compartmetn omuscles, loose pack more prone to injuries 

5

inversion 

tibialis anterior 

tibialis posterior 

6

eversion 

fibularis longus , 

fibularis brevis 

fibularsi ter

 

7

flexion 

flexion and extension

talocrual (ankle) joint 

 

inversion and eversion (inter

8

Rolled ankle

  • rolled ankle--> inversion spain 
    • most commmon torn anterior talkvoinular ligament
  • sprain 
    • eversion
    • medial deltoid ligament 

9

hight ankle sprain 

rotational injury where the foot is forcefully turned otu away from midline

tear of sundesmotic ligaments of andkle

distal tibioligaments (ant and post)

interosseus membrane

 

body rotates on fixed foot

10

medial and lateral longitudian larches 

transverse arch

 

ligaments: long plantar lig 

short plantatar lig 

spring ligament 

fibularis longus tendon 

 

11

pes planus

  • archs collapeses
  • entrie sole of foot in contact with the flood
  • some arches neever develop 
  •  

12

bunions

lateral deviation of the great toes, with lateral displacemetn of sesamoind bones 

begause degenration joint disease and pressure from footwear

great toe can overlat 2nd toe

can lead to an aquired bursa whtich onve inflanmes 

13

talipes equinovarus

congenital defects

around the subtalar joint
