Hip and pelvis

Question 1

Portions of the femur

Answer 1

Head, neck, shaft and fovea.

Question 2

Portions of the innominate

Answer 2

Ischium, ilium, pubis and acetabulum

Question 3

Fovea

Answer 3

Small, round area of cancellous bone tissue on the head of the femur

Question 4

Acetabular notch

Answer 4

Anterior, inferior aspect of the acetabulum

Question 5

Joint capsule tissue

Answer 5

Dense, irregular connective tissue

Question 6

Ligament tissue

Answer 6

Dense, regular connective tissue

Question 7

Acetabular labrum

Answer 7

Fibrocartilagenous ring around the perimeter of the acetabulum. Deepens the socket and increases joint congruency

Question 8

Extracapsular ligaments of the hip

Answer 8

Iliofemoral, ischiofemoral and pubofemoral

Question 9

Iliofemoral ligament

Answer 9

Strongest ligament of the hip joint. Shaped like an upside down Y. Attaches the ilium to the anterior femoral neck.

Question 10

Motions resisted by the iliofemoral ligament

Answer 10

Excessive hip extension and lateral rotation.

Question 11

Ischiofemoral ligaments

Answer 11

Weakest ligament of the hip. Attaches from the ischium (lateral to the ischial tuberosity) to the superior aspect of the femoral neck.

Question 12

Motions restricted by the ischiofemoral ligaments

Answer 12

Excessive hip extension and medial rotation.

Question 13

Strongest ligament of the hip hoint

Answer 13

Iliofemoral

Question 14

Weakest ligament of the hip joint

Answer 14

Ischiofemoral

Question 15

Pubofemoral ligament

Answer 15

Runs body of the pubis to the medial neck of the femur. Restricts excessive extension and abduction.

Question 16

Intracapsular ligaments of the hip

Answer 16

Ligamentum teres and transverse acetabular ligament

Question 17

Ligamentum teres

Answer 17

Round and tube-like ligament that attaches from the fovea to the acetabulum. Functions as a conduit for an artery.

Question 18

Lesser sciatic notch

Answer 18

A notch within the ischium

Question 18

Transverse acetabular ligament

Answer 18

Fills the acetabular notch. Functions to increase joint congruency.

Question 19

Greater sciatic notch

Answer 19

Large, inverted U shaped indentation on the posterior margin of the lower ilium.

Question 20

Ischial spine

Answer 20

A spine of bone which separates the greater and lesser sciatic notches.

Question 21

Bones of the pelvis

Answer 21

Right and left innominates, sacrum and coccyx.

Question 21

Articulatory surfaces of the sacroiliac joint

Answer 21

The sacrum (convex) and the ilium (concave)

Question 22

The sacrum is part of which portion of the skeleton?

Answer 22

Axial

Question 23

The ilium is part of which portion of the skeleton?

Answer 23

Appendicular

Question 24

The superior leg of the SI joint

Answer 24

Synovial, but covered with fibrocartilage. Functions as a gliding joint.

Question 25

The inferior leg of the SI joint

Answer 25

Amphiarthrosis

Question 26

Ligaments of the SI joint

Answer 26

Sacroiliac, sacrotuberous, sacrospinous and ilioumbar

Question 27

Sacroiliac ligaments

Answer 27

Includes the anterior, posterior and interosseous SI ligaments. Support and stabilize the sacrum through gait.

Question 28

Strongest ligaments of the SI joint

Answer 28

Sacroiliac ligaments.

Question 29

Sacrotuberous ligaments

Answer 29

Attaches from the posterior ILA of the sacrum and the ischial tuberosity. Creates the inferior border of the lesser sciatic foramen. Palpable and painful if the joint is dysfunctional.

Question 30

Sacrospinous ligament

Answer 30

Attaches from the anterior ILA to the ischial spine. Not as strong as the other sacroiliac ligaments. Creates the border which divides the greater and lesser sciatic foramina.

Question 31

Iliolumbar ligament

Answer 31

Attaches from the posterior iliac crest to the transverse processes of L4 and L5. Indirectly stabilizes the sacrum.
