Flashcards in Joints of the Hip Complex Deck (25):
1

Components of the hip bone

Ilium
Ischium
Pubis

2

type of articulation of the hip

ball and socket

3

What is the name of the articular face of the hip? what bones make it?

Acetabulum
Ileum, Ischium and Pubis

4

most important parts of the proximal portion of the femur?

head, fovea
anatomical neck
Greater and lesses trochanter

5

in the proximal end of the femur, relevant epiphysis

head == pressure epiphysis
greater trochanter == traction epiphysis

6

what part of the head of the femur is not inside the socket of the acetabulum and what structure protects it?

the anterior surface and it is covered by psoas bursa [not communicating with the joint]

7

what part of the hip one sits on?

ischial tuberosity

8

what is the labrum and what are their functions?

rim of cartilage that surrounds the acetabulum, filled with synovial fluid, in charge of increasing the surface of articulation

9

the main function of the ligament of the head of femur is mechanical support T/F

F, arteries to the femur that die off after puberty

10

what are the trabecular systems and how many are there?

2 trabecular systems and they are the lines of weight baring support of the muscle (superior: [arcuate and vertical] and inferior: [medial-lateral])

11

line of gravity passes behind the pelvic articulation T/F

T

12

how many ligaments reenforce the pelvic joint?

3 ligaments
IlioFemoral [anterior, direct attachment to the femur, inverted Y]
PuboFemoral
Ischiofemoral

13

where does the capsule attach to the femur?

at the base of the neck

14

what is the main ligament responsible for the strength of the joint?

iliofemoral, locks and medially rotates

15

what arteries run in the capsule of the joint what what do they supply? where to they come off? what are they branches off?

Retinacular Arteries
supply the neck and head of the femur
from the lateral/medial circumflex artery
from Femoralis Profunda

16

when does medial and lateral rotation occur?

medial stance
lateral swing

17

what is the main function of gluteus medius and minimus?

abduction and maintaining of the position on the coronal plane on swing phase. They contract and pull downwards

18

what nerves five supply to the hip joint?

articular branches of femoral and obturator nerve

19

Myotomes of hip flexion

L2-3

20

Myotomes of hip extension

L4-5

21

what structure lies behind the pelvic articulation and might be damaged in a-p dislocation?

Sciatic Nerve

22

coxa valga is?

when the head of the femur articulates in an gale to more than 125 degrees casing the keens to be more inwards than normal

23

coxa vara is?

when the head of the femur articulates in an gale to less than 120 degrees casing the keens to be more outwards than normal increasing the strain on the neck

24

if the femur is fractures what happens with the limb?

external rotation and shortening of the limb due to muscle spams

25

Osteoarthritis (OA) is ....

painful, degenerative joint disease that often involves the hips, knees, neck, lower back, or small joints of the hands. OA usually develops in joints that are injured by repeated overuse from performing a particular task or playing a favorite sport or from carrying around excess body weight. Eventually this injury or repeated impact thins or wears away the cartilage that cushions the ends of the bones in the joint. As a result, the bones rub together, causing a grating sensation. Joint flexibility is reduced, bony spurs develop, and the joint swells. Usually, the first symptom of OA is pain that worsens following exercise or immobility. Treatment usually includes analgesics, topical creams, or nonsteroidal anti-inflammatory drugs (known as NSAIDs); appropriate exercises or physical therapy; joint splinting; or joint replacement surgery for seriously damaged larger joints, such as the knee or hip.
