dip

Question 3

joints of ankle and foot

Answer 3

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

Question 4

motions ofankle

Answer 4

doris flexion

anterio leg compartment , closed pack tight fit

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

Question 5

inversion

Answer 5

tibialis anterior

tibialis posterior

Question 6

eversion

Answer 6

fibularis longus ,

fibularis brevis

fibularsi ter

Question 7

flexion

Answer 7

flexion and extension

talocrual (ankle) joint

inversion and eversion (inter

Question 8

Rolled ankle

Answer 8

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

Question 9

hight ankle sprain

Answer 9

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

Question 10

medial and lateral longitudian larches

Answer 10

transverse arch

ligaments: long plantar lig

short plantatar lig

spring ligament

fibularis longus tendon

Question 11

pes planus

Answer 11

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

Question 12

bunions

Answer 12

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

Question 13

talipes equinovarus

Answer 13

congenital defects

around the subtalar joint
