Flashcards in 02 Hip 1 Deck (50):
1

relative motion has to do with

when you move one body part, what's happening at the others

2

pelvic girdle

os coxa

3

How is the pelvic girdle attached to the axial skeleton?

- SI joints
- pubic symphysis

4

qualities of the SI joint and pubic symphysis

- very stable
- permits little movement

5

How does movement of the os coxa occur?

movements at the hip joint and the lumbar vertebral joints

6

3 pelvis bones

- ilium
- ischium
- pubis

7

What is the acetabulum?

combination of all 3 pelvic bones

8

ligamentum teres significance

- doesn't do anything in terms of stability
- blood supply to femoral head goes through here

9

Where ligamentum teres enters

fovea

10

Legg Perthes disease

avascular necrosis of the femoral head

11

The acetabulum is deepened by a ________

labrum

12

Are hip diseases common?

yes

13

Who commonly gets hip disease?

- very young
- elderly

14

AVN is most common in

young people

15

hip disease most common in old people

OA

anal area

30

angle of inclination is between

shaft and neck of femur in coronal plane

31

angle of torsion

- angle between the femoral neck and plane of the femoral condyles
- in horizontal plane

32

During _________, the position of rest produces in-toeing

excessive anteversion

33

During _________ and _________, the position of rest produces out-toeing

- retroversion
- abnormally small anteversion

34

normal anteversion

15˚

35

What are the 3 ligaments of the hip we talk about?

- iliofemoral
- pubofemoral
- ischiofemoral

36

anterior ligaments of the hip

- iliofemoral ligament
- pubofemoral ligament

37

most powerful ligament in the body

iliofemoral

38

iliofemoral ligament

- the Y ligament
- limits hip extension

39

pubofemoral ligament

- limits abduction and extension

40

posterior ligament

ischiofemoral ligament

41

What does the ischiofemoral ligament do?

limits flexion

42

gateways to the lower limb

- greater sciatic foramen
- lesser sciatic foramen
- obturator canal
- gap between inguinal ligament and pelvic bone

43

Where does the aorta branch to form the iliac artery?

umbilicus

44

blood supply
level of inguinal ligament (between ASIS and pubic tubercle)

iliac artery turns into the femoral artery

45

Which arteries are susceptible to damage by fracture?

medial and lateral femoral circumflex

46

artery of the ligamentum teres is a branch of the

obturator artery

47

The obturator artery is frequently obstructed in

older people

48

open chain movement of the hip - arthrokinematics

convex on concave

49

closed chain movement of the hip - arthrokinematics

concave on convex

50

right side - anterior pelvis rotates the spine
