Flashcards in Hip Deck (41):
1

What happens to the angle of inclination in coxa vera?

The angle of inclination decreases

2

What happens to the angle of inclination in coxa valga?

The angle of inclination increases

3

What is the Angle of inclination? What plane is it in?

The angle btwn the neck and the shaft of the femur. ~125 degrees. The frontal plane

4

What is the angle of torsion?

A line drawn from the head and neck of femur to a line drawn through the femoral condyles

5

What plane is the angle of torsion in?

Transverse

6

What is excess anteversion?

pathological Increase in angle of torsion

7

What is retroversion?

pathological decrease in angle of torsion

8

How much anteversion do we normally have?

15 degrees of torsion

9

What happens to the toes with ante version of femur?

Toes pointed in

10

What happens to the toes during retroversion of the femur?

Toes pointed out

11

What are the arthrokinematics of the hip joint during flexion?

Posterior glide

12

What are the arthrokinematics of the hip joint during Extension?

Anterior glide

13

What are the arthrokinematics of the hip joint during Adduction?

Superior/lateral glide

14

What are the arthrokinematics of the hip joint during Abduction?

Inferior glide

15

What are the arthrokinematics of the hip joint during Lateral Roatation?

anterior glide

16

What are the arthrokinematics of the hip joint during medial rotation?

posterior glide

17

In the entire capsule, which portion is thicker, which is thinner?

The anterior capsule is thinner than the posterior capsule

18

In the anterior capsule, which part is thicker?

The anterior/superior part of the anterior capsule is the thicker part

19

In the posterior capsule, which part is thinner?

The posterior/inferior part of the posterior capsule

20

What are the three hip joint ligaments?

The iliofemoral ligament (anterior, y ligament), the ischiofemoral ligament (posteriorly) and the pubofemoral (anterior, inferior) ligament

21

What motion do the ligaments undergo to maintain stability?

Torsion (twisting)

22

What are the two types of bone in the femur?

Cortical bone-outer, structure hards
Cancellous bone-trabecular/spongy inner structure

23

Which type of bone does osteoporosis affect?

Trabecular bone

24

What type of bone is compromised in a hip fracture?

Cortical bone

25

What plane is pelvic rotation in?

Transverse plane

26

What plane is medial/lateral pelvic till in?

Frontal (hip hike, pelvic drop)

27

Forward rotation of the pelvis is associated with what motion of the stance limb on the contralateral side?

Internal rotation

28

Backwards rotation of the pelvis is associated with what motion of the stance limb on the contralateral side?

External Rotation

29

What is a Trendelenberg sign?

Hip drop due to contralateral glute medius weakness

30

What are the flexor muscles?

Iliopsoas, sartorius, rectus femorus

31

What are the extensors?

Gluteus maximus, gluteus medius, biceps femoris, semitendonisis

32

What are the abductors of the leg?

gluteus medius, gluteus minimus, TFL, Sartorius

33

What are the adductors of the leg?

Adductor longus, Adductor brevis, Adductor magnus, pectineus, gracilis

34

What are the lateral rotators of the leg?

piriformis, gemellus superior, gemellus inferior, quadratus femoris

35

When the knee is in flexion and the hip is in extension, what is the action of the adductor longus ?

Hip FLEXION

36

When the knee and hip are fully flexed what is the action of the adductor longs?

Hip EXTENSION

37

Why doesn't the hip have any purely internal rotators?

The hips natural inclination is to fall into internal rotation so the adductors will primarily pull the leg into IR

38

What does HAT stand for?

Head, arm and trunk

39

What are two different treatments for Tredelenberg gait?

Cane assisted gait on contralateral side or lateral lean

40

What will happen to the hip with a lateral lean?

Lean toward the weaker side. Increases the axial compression in the hip

41

What is the most common hip dislocation?

Posterior inferior dislocation
From sitting and you lean to pick up something off the floor.
