16
Q

what is the primary function of the SIJ

A

to distribute force in the stable pelvic ring

17
Q

what is the angle of inclination

A

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

18
Q

what is a normal angle of incliation

A

125

19
Q

what does coxa valga go with?

A

genu varum

20
Q

what does coxa vara go with?

A

genu valgum

21
Q

what is a normal angle of torsion

A

8-15 degrees

22
Q

what closes off the acetabulum

A

transverse acetabular ligament

23
Q

what does the labral seal do

A
  • may provide stability
  • does protect articular cartilage through pressurization
  • if you have a seal, synovial fluid cant leak out and ruin the cartilage
24
Q

what does the fibrous joint capsule do

A
  1. encapsulates joint

2. provides stability

25
Q

what does the iliofemoral Y ligament do

A
  • can hold the body weight balanced over the femoral heads

- tightens up with ER, IR, Ext

26
Q

when does the pubofemoral lig tighten

A

Ext

ER

27
Q

when does the ischiofemoral lig tighten

A

Ext
IR
adduction

28
Q

what are hip osteokinematics with flexion

A

spin with slight inferior

posterior glide at terminal motion

29
Q

what are hip osteokinematics with extension

A

spin with slight anterior

superior glide at terminal motion

30
Q

what are hip osteokinematics with ER

A

anterior glide

31
Q

what are hip osteokinematics with IR

A

posterior glide

32
Q

what are hip osteokinematics with adduction

A

superior glide

33
Q

what are hip osteokinematics with abduction

A

inferior glide

34
Q

what is coxa vara

A

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.
35
Q

what is coxa valgus

A

140 or >125

  • Sup to the center of the acetabulum
  • Creates genu varus
  • Increased force on the muscles for stability with SL stance.
36
Q

what is excessive anteversion

A

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

37
Q

what is retroversion

A

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