Hip

Question 1

angle of inclination

Answer 1

femoral head and neck

occurs on frontal plane

Question 2

Coxa Valga

Answer 2

>125 on angle of inclination

Question 3

Coxa Vara

Answer 3

Angle of inclination < 125

Question 4

angle of inclination serves to

Answer 4

optimaize joint surface alignment

Question 5

Coxa Vara with high BMI

Answer 5

can result in slipped capital femoral epiphysis

Question 6

Coxa vara pros and cons

Answer 6

pros increased mvmt arm from AB improve joint stability

cons increased bending moment arm icreases shear force and decreased fuctional length of hip AB

Question 7

Coxa Valga pros and cons

Answer 7

pros - decreased bending mvmt arm decrases shear force and increased functional length of AB

cons decreased mvmt arm for AB and alignment may favor dislocation

Question 8

angle of torsion

Answer 8

occurs in tansverse plane

15 degrees of anteversion

axis between head and femoral condyles

Question 9

excessive anteversion on femur

Answer 9

incrases angle of torsion

reduces hip stability increased hip IR

commonl found with COXA VALGA

toe in gait

increases mvmt arm of AB

Question 10

retroversion

Answer 10

decreasedd angle of torsion

increased hip ER

may casue impingement

Question 11

shoulder vs hip angulation

Answer 11

shoulder retroversion

hip is anterversion

Question 12

Coxa profunda

Answer 12

acetabular overcoverage more than 45 degrees

Question 13

dysplasia

Answer 13

acetabular undercoverage less than 16 degrees

Question 14

femor head coverage is determined by

Answer 14

acetabular depth

center edge angle

Question 15

FAI cam

Answer 15

loss of natural tapering

inpingement may occur

Question 16

FAI pincer

Answer 16

bony extension on acetabulum

deep acetabulum or overly retroverted

Question 17

Max conguency in NWB acetabularfemoral

Answer 17

FL AB slight ER

Question 18

forces on head of femur

Answer 18

top/superior head = tensile forces

bottom or inferior head = compressive forces

Question 19

trabecullar systems in femur

Answer 19

strongest where they cross

weakest where they do not corss or thin

Question 20

hip joint capsule

Answer 20

capsule thick anterior superiorly

thin and loose posterior inferiorly

Question 21

iliofemoral lig

Answer 21

ant stability

IR and ER

Question 22

pubofemoral

Answer 22

controls ER and EX

Question 23

ischiofemoral lig

Answer 23

primary resist to IR

Question 24

ligs that support you in hyperex

Answer 24

iliofemor pubofemoral ischiofemoral

Question 25

anterior pelvic tilt

Answer 25

produces hip FL

Question 26

posterior pelvic tilt

Answer 26

hip EX

Question 27

lateral pelvic tilt

Answer 27

talk about whats heppening with hip that has the foot incontact with the ground

Question 28

right pelvic hiking

Answer 28

AB at the hip on L

Question 29

right pelvic drop

Answer 29

AD at hip on L

Question 30

closed packed hip

Answer 30

full EX slight IR and AB NOT MX CONGUENCY

Question 31

open packed hip

Answer 31

some FL slight AB neutral rotation

Question 32

capsular pattern hip

Answer 32

IR=FL=AB

Question 33

reason abs activate with SLR

Answer 33

abs need to activate to resist offset the anterior pelvic tilt happening with hip FL

Question 34

saggital Fx of AD longus with hip FL and EX

Answer 34

with hip FL - contributes to EX with hip EX - contributes to FL

Question 35

benfit of AD longus with bidirection torque

Answer 35

good for high power cyclic motion

Question 36

weakness in glute med in SL

Answer 36

will result in pelvic drop trendelenburg sign
