Answer 3

acetabulum to the neck
intertrochanteric line
intertrochanteric crest of femur

Question 4

what are the attachments of the iliofemoral lig

Answer 4

AIIS

intertrochanteric line of femur

Question 5

what are the actions of the iliofemoral lig

Answer 5

limits extension of femur

becomes taught with ER

Question 6

what are the attachments of the pubofemoral lig

Answer 6

iliopubic eminence

superior pubic ramus to fibrous capsule

Question 7

what are the actions of the pubofemoral lig

Answer 7

limits abduction of femur

becomes taught with ext and ER

Question 8

what are the attachments of the ischiofemoral lig

Answer 8

iscihum post to acetabulum
greater troch
iliofemoral lig

Question 9

what are the actions of the ischiofemoral lig

Answer 9

assists iliofemoral lig in limiting extension of femur

Question 10

whats the attachment of the ligament of the head of the femur (ligamentum teres)

Answer 10

fovea of femoral head

actebaular notch

Question 11

what are the attachments of the transverse acetabular lig

Answer 11

interconnects margins of the acetabular notch

Question 12

what kind of joint is the SI joint

Answer 12

planar

Question 13

what are the stabilizers of the SI joint

Answer 13

sacrospinous

sacrotuberous

Question 14

what is nutation (inferoposterior glide)

Answer 14

occurs in standing
superior moves ant + inf
inferior moves post + sup

Question 15

what is counter nutation (anterosuperior glide)

Answer 15

superior moves post

inferior moves anterior

Question 16

what is the primary function of the SIJ

Answer 16

to distribute force in the stable pelvic ring

Question 17

what is the angle of inclination

Answer 17

the angle of the femoral head and neck on shaft of femur

Question 18

what is a normal angle of incliation

Answer 18

125

Question 19

what does coxa valga go with?

Answer 19

genu varum

Question 20

what does coxa vara go with?

Answer 20

genu valgum

Question 21

what is a normal angle of torsion

Answer 21

8-15 degrees

Question 22

what closes off the acetabulum

Answer 22

transverse acetabular ligament

Question 23

what does the labral seal do

Answer 23

• may provide stability
• does protect articular cartilage through pressurization
• if you have a seal, synovial fluid cant leak out and ruin the cartilage

Question 24

what does the fibrous joint capsule do

Answer 24

1. encapsulates joint

2. provides stability

Question 25

what does the iliofemoral Y ligament do

Answer 25

- can hold the body weight balanced over the femoral heads | - tightens up with ER, IR, Ext

Question 26

when does the pubofemoral lig tighten

Answer 26

Ext | ER

Question 27

when does the ischiofemoral lig tighten

Answer 27

Ext IR adduction

Question 28

what are hip osteokinematics with flexion

Answer 28

spin with slight inferior | posterior glide at terminal motion

Question 29

what are hip osteokinematics with extension

Answer 29

spin with slight anterior | superior glide at terminal motion

Question 30

what are hip osteokinematics with ER

Answer 30

anterior glide

Question 31

what are hip osteokinematics with IR

Answer 31

posterior glide

Question 32

what are hip osteokinematics with adduction

Answer 32

superior glide

Question 33

what are hip osteokinematics with abduction

Answer 33

inferior glide

Question 34

what is coxa vara

Answer 34

115 or <125 - inf to the center of the acetabulum - Creates genu valgum (knock knee) - Increases force on the femoral neck. - More coverage leading to increased risk of impingement.

Question 35

what is coxa valgus

Answer 35

140 or >125 - Sup to the center of the acetabulum - Creates genu varus - Increased force on the muscles for stability with SL stance.

Question 36

what is excessive anteversion

Answer 36

-increased angle/ ant rotation of the femoral head (in front of the center point on the acetabulum) -creates a toe in

Question 37

what is retroversion

Answer 37

-decreased angle/ post rotation of the femoral head (behind the center point on the acetabulum) -creates toeing out
