Flashcards in MSK - The Hip Bone Deck (31):
1

The two symmetrical hip bones are part of what structure?

The Pelvic Girdle

2

What attachments of the skeleton does the pelvic girdle make?

Attaches the axial skeleton to the lower limbs

3

How many articulations do the hip bones have and what do they articulate with?

What are the names of the articulations?

Sacroiliac Joint - Articulates with the sacrum

Pubic Symphysis - Articulates with corresponding hip bone

Hip Joint - Articulates with head of the femur

4

How many parts is the hip bone made up of?

Name these parts

3

Ilium, Pubis and Ischium

5

What separates these three parts and when do they start fusing and when do they finish?

 The Triradiate Cartilage

Begin at ages 15-17

Finish at around 20-25 years

6

The fusion of the three parts of the hip bone forms what?

What articulates here?

Their fusion forms a cup-shaped socket known as the acetabulum

The head of the femur articulates with the acetabulum to form the hip joint

7

What part of the hip bone is most superior, largest and widest?

The Ilium

8

What part of the acetabulum does the Ilium form?

The superior part

9

What part of the Ilium is immediately above the acetabulum?

The Wing of Ilium

10

What are the two surfaces of the Wing of Ilium?

What shapes are they?

What groups of muscles do they provide attachments for?

Inner Surface (Iliac Fossa) is concave and provides muscle attachment for the iliacus muscle

Outer Surface (Gluteal Surface) is convex and provides muscle attachment for gluteal muscles

11

What margin of the Ilium is thickened?

What structure does this form?

Where does this structure extend from and to?

Superior Margin thickened

Forms the Iliac Crest

Extends from the Anterior Supererior Iliac Spine (ASIS) to the Posterior Superior Iliac Spine

 

 

12

What does the ASIS provide attachment for?

The Inguinal Ligament

13

Where else does the Inguinal Ligament attach apart from the ASIS?

To the Pubic Tubercle

14

What can be palpated midway along the inguinal ligament?

What is found laterally to this?

The femoral artery

Laterally to the F.E is the Femoral Vein

15

How can True Leg Length be measured?

Measured from the ASIS to the Medial Malleolus of the Ankle Joint

16

How can Apparant Leg Length be measures?

From the Umbilicus to the Medial Malleolus

17

What are the green, yellow and red highlighted areas?

What part of the hib bone does this make?

Ultimately makes up the Pubis

18

What is the labelled hole known as?

19

What passes through the obturator foramen?

The obturator nerve, artery and vein

20

What overall structure is composed of the three highlighted structures? 

Label the highlighted structures

The Ischium

21

The inferior ischial ramus combines with what pubic structure to form what overall structure?

The inferior pubic ramus and the inferior ischial ramus combine to form the ischiopubic ramus

22

What does the ischiopubic ramus enclose part of?

The obturator foramen

23

What is being labelled?

What is the function of this bony landmark?

The Ischial Tuborosity

When sitting, our body weight falls on these

24

Please label the rest of the Ischial Bony Landmarks

25

What are the important ligament attachments to the Ischium?

The Sacrospinous Ligament and the Sacrotuberous Ligament

26

Where does the Sacrospinous Ligament run from and to?

What does this create?

What runs through here?

Runs from the Ischial Spine to the Sacrum creating the Greater Sciatic Foramen through which the lower limb vasculature (including the sciatic nerve) and pisiformis muscle transend

27

The Lesser Sciatic Foramen is formed by what?

The Sacrospinous Ligament and the Sacrotuberous Ligament

28

What are the two common ways that the hip bone might be fractured?

Direct Trauma

Forces Transmitted to the lower limb (eg in heavy fall onto the feet)

29

What are the weaker points of the hip bone?

Pubic Rami

Acetabulum

Sacroiliac Joint

30

What are some common complications with hip bone fractures? 

 

Soft Tissue Injury particularly in the bladder or utethra

31

What has happened in this X-Ray?

Fracture of the left pelvic bone. The femoral head has been driven through the acetabulum.
