Flashcards in The Hip Joint Deck (24):
1

Bones of the pelvic girdle

Left and right innominate bones
Sacrum

2

Joints of the Pelvic Girdle

2 Sacroiliac Joints
Pubic Symphisis joints

3

Anatomical position of the pelvic girdle

ASIS and Pubic tubercles in same Coronal Plane

4

Area of fusion of Ilium, Ischium and Pubis

Acetabulum

5

Type of joint at the acetablulum

Ball and Socket Synovial Joint

6

Ligament completing the Acetabular labrum

Transverse Acetabular Ligament

7

Fibrous Capsule attachments

Proximally: Rim of Acetabulum

Distally: Femoral Neck (Intertrochanteric line and greater trochanter)

8

Ligaments of the Hip Joint?

Iliofemoral
Ischiofemoral
Pubofemoral

9

Which is the strongest ligament

Iliofemoral

10

Which is the weakest ligament

Ischiofemoral

11

Which ligament covers the joint posteriorly

Ischiofemoral

12

When are the ligaments taut?

When the hip is extended- they pull the femoral head into the acetabulum

13

Which ligament prevents excessive abduction

Pubofemoral

14

Which ligament presents hyperextension

Iliofemoral

15

Which ligament covers the joint Anteriorly and Inferiorly

Pubofemoral

16

Which ligament covers the joint Anteriorly and Superiorly

Iliofemoral

17

Movements of the Hip

Flexion/Extension
Abduction/Adduction
Medial/Lateral Rotation

18

Features of a Pubic Rami #

Indicates fall if unilateral
Significant TRM if bilateral

19

Features of Open Book Pelvic #

Opening of Pubic Symphysis
Significant Anterior Trauma

20

Features of #NOF

Often due to Osteoporosis
20% cases have AVASCULAR NECROSIS (secondary to vessel rupture/stretching)

May require a hip replacement

21

Features of DDH (Developmental Dysplasia of Hip)

Common In Females

Due to low Amniotic Fluid levels/baby born in breech

Laxity of ligaments causes dislocation

22

Features of Anterior Hip Dislocation

Force applied to Abducted/ Laterally rotate hip

Head levered out Anteriorly

Femoral Neurovasculature at risk of damage

23

Features of Posterior Hip Dislocation

Trauma to Adducted/Medially Rotated/Flexed hip

e.g. car crash

Sciatic Nerve at risk of damage

24

Features of Medial Dislocation (Acetabular #)

Femoral Head is forced through acetabulum on lateral impact

May be associated with internal damage
