Question 0

Acetabulum depth measured by

Answer 0

center edge angle
center of femoral head to acetablum (Bone)
measures rook over femural head or contact area

Question 1

Hip coxofemoral joint

Answer 1

ball socket 3 DOF

weight bearing

Question 2

decrease center edge angle

Answer 2

dyplasia instability shallow lack coverage

Question 3

increase center angle

Answer 3

decrease ROM, impingement increase coverage

Question 4

acetabulum seats how

Answer 4

laterally inferiorly and anterior tilt 38 degree

Question 5

labrum

Answer 5

fibrocartilage deepens socket wedge shaped

proprioceptive nerve ending

Question 6

femoral head

Answer 6

w/ hyaline cartilage except fovea (ligamentum teres)

Question 7

Angle of inclination norm

Answer 7

down shaft and up neck to head of femur

110-144 frontal plane

Question 8

coxa valga

Answer 8

increased angle
decreased MA of hip ABD
knock knees
decrease force on neck bending

Question 9

coxa vara

Answer 9

decrease the angle
increase MA of hip ABD
bow legged
increase force neck of femur

Question 10

femoral torsion norms

Answer 10

condyles of knee and head of femur
10 to 20
transverse plane

Question 11

femoral torsion anteversion

Answer 11

>15-20
increase IR Decrease ER
decrease MA ABD
condyles of knee medially rotated
increase Q angle

Question 12

femoral torsion retroversion

Answer 12

<15 to 20

increase ER and decrease IR

Question 13

Articular congruence best position

Answer 13

Hip flexed and ABD with ER

contact btw femur and acetabulum greatest

Question 14

Answer 15

iliofemoral a
pubofemoral a
ishiofemoral p
ALL TIGHT IN EXTENSION OF HIP

Question 16

closed pac position of HIP

Answer 16

EXT slight ABD IR of hip

Question 17

car accident example

Answer 17

hip flexed ADD most vulnerable position

posterior subloxation

Question 18

Hip flexion degrees

Answer 18

90 knee straight giving passive insuff of hamstrings

120 knee flexed

Question 19

closed chain

Answer 19

femur fixed pelvis motion

Question 20

anterior pelvic tilt

Answer 20

hip flexed and lumbar ext (seating upright at desk leaning forward)
errector spinae, illiopsoas, rectus femurs

Question 21

Posterior tilt

Answer 21

hip extended lumbar spine flexed

rectus ABD, glut max, hamstrings

Question 22

lateral tilt

unilateral standing on L HIP = R HIP HIKE

Answer 22

L - ABD
R - ADD
lumbar flex right

Question 23

bilateral pelvic tilit

R pelvic DROP

Answer 23

L - ADD
R - ABD
lumbar flexion L

Question 24

Gait rotation R hip walking pattern

Answer 24

R hip

ER w/ right foot forward
IR w/ right backwards

forward foot always ER and backward foot always IR

Question 25

HAT

Answer 25

heads Arms trunk 2/3s BW

Question 26

When standing on one leg what what happens (R LEG ex)

Answer 26

compensating by leaning to the right side dec MA of BW

and shifting COM to towards right side

Question 27

TRENDALENBERG

Answer 27

glut med weakness pain (antalgic gait)

Question 28

signs of trendelenburg

Answer 28

pelvic drop due to weak hip abd
weak left hip ABD - pelvic drop to the right

hip abd cant abd pelvis back to neutral in closed chain walkin

Question 29

Trendalenberg (+) signs

Answer 29

when standing on the right leg if the left hip drops its a (+) sign for right hip ABD weakness

pts will lean to affected side while walking in order to try to clear the L hip

Question 30

Femoral acetabular impingement FAI

Answer 30

hip bones rub against each other

Question 31

Femoral acetabular impingement FAI ( pincer )

Answer 31

superior acetabulum impinged tears ossification degeneration to anter superior labrum of acetabulum

Question 32

Femoral acetabular impingement FAI CAM lesions

Answer 32

lesions of femoral neck/head impingement usually caused excess bone rubbing
