Flashcards in 02 Hip 2 Deck (44):
1

hip flexors are attached on

anterior pelvis

2

hip extensors

posterior: gluteal, hamstrings

3

hip abductors

anterior short gluteals

4

hip adductors are found at

medial thigh: adductors

5

hip internal rotators

anterior short gluteals

6

hip external rotators

posterior gluteals

7

What are the compartments of the thigh?

- anterior
- medial
- posterior

8

Where does the femoral artery run in the thigh compartments?

between the anterior and medial compartments

9

What's in the anterior thigh compartment?

knee extensors

10

What's in the medial thigh compartment?

hip adductors

11

What's in the posterior thigh compartment?

- hip extensors
- knee flexors

12

major bony landmarks

Where do gluteal muscles attach?

greater trochanter

13

major bony landmarks

What attaches to lesser trochanter?

iliopsoas

14

What attaches to the linea aspera?

adductors

15

What is the largest nerve in the body?

sciatic

16

Where does the sciatic nerve exit most of the time?

- exits the greater sciatic foramen
- below the piriforis

17

What happens if the sciatic nerve passes through the piriformis?

piriformis compresses through sciatic nerve

18

What are the external rotators of the hip joint?

short gluteals

19

piriformis syndrome

- piriformis muscle goes into spasm » increases size
- compresses the sciatic nerve

aka sciatica

20

Why do we only talk about the piriformis as opposed to the other short gluteals?

- more extensive attachment points compared to the other rotators
- it's the only one connected to the sacrum

21

line of pull of the piriformis with the hip in anatomical position

external rotator like other short gluteals

22

line of pull of the piriformis with the hip in flexion

abductor

23

hip flexors

- iliacus and psoas (iliopsoas)
- sartorius
- rectus femorus

24

saphenous opening

inferior to the medial end of the inguinal ligament

25

saphenous opening allows entry of the __________ to joint the ___________

great saphenous vein to join the femoral vein

26

the saphenous opening is in the

fascia lata

27

hip adductors

- pectineus
- adductor longus
- adductor brevis
- adductor magnus
- gracilis

28

groin muscles

adductors

29

If the hip is in flexion, the adductors are hip __________

adductors
extensors

30

If the hip is in extension, the adductors are hip ___________

adductors
flexors

31

major hip extensors

- gluteus maximus
- hamstrings

32

hip abduction occurs via action of the

- gluteus medius
- gluteus minimus
- tensor fascia lata

33

When the foot is on the ground, hip abduction produces

elevation of the contralateral side of the pelvis

34

closed chain hip extension produces

- posterior pelvic tilt with lumbar flexion = nutation
- flat back

35

closed chain hip flexion produces

- anterior pelvic tilt with lumbar extension = counternutation
- excessive lordosis

36

What produces anterior pelvic tilt?

lumbar extensors
- erector spinae

hip flexors
- iliopsoas
- sartorius
- rectus

37

posterior pelvic tilt is a force couple produced by:

- rectus abdominis
- hip extensors (glute max and hamstrings)

38

posterior pelvic tilt is a combination of

- hip extension
- lumbar flexion

39

What happens when you have weak abs and attempt a straight leg raise?

- lumbar extension
- anterior pelvic tilt

40

What happens during a straight leg raise with abdominal muscle strength?

- RA maintains flexion and flat back
- allows action of iliopsoas, rectus femoris to produce hip flexion

41

What do the internal rotators do to the hip during stance phase?

rotate the opposite side of the pelvis forward

42

normal angle of inclination

125˚

43

coxa vara

angle of inclination
105˚

44

coxa valga

angle of inclination
140˚
