Question 1

Ligamentum Teres

1) origin
2) insertion
3) what movement will it ‘check’

Answer 1

1) acetabula notch
2) fovea capitus
3) adduction, flexion & external rotation

Question 2

Iliofemoral Ligament (Y ligament)

1) origin
2) insertion
3) what movement will it ‘check’

Answer 2

1) AIIS & acetabula rim
2) intertrochanteric line
3) hyperextension, lateral rotation & adduction / aid upright posture by reducing the need for muscle contraction

Question 3

Pubofemoral Ligament

1) origin
2) insertion
3) what movement will it ‘check’

Answer 3

1) obturator crest of pubic rami

(passes laterally and inferiorly)

2) inferior end of intertrochanteric line
3) hyperextension, lateral rotation & abduction

Question 4

Ischiofemoral Ligament

1) origin
2) insertion
3) what movement will it ‘check’

Answer 4

1) ischial part of acetabula rim

(passes superolaterally)

2) medial surface of greater trochanter
3) hyperextension medial rotation

Question 5

what is the Articular Capsule made of and its function

Answer 5

• made of connective tissue reinforced by ligaments
• synovial membrane lines the inside which secrets synovial fluid which lubricates the joint & helps maintain negative pressure
• strong force of co-aption for stability

Question 6

Articular Capsule

1) origin
2) insertion

Answer 6

1) margin of acetabulum

2 intertrochanteric line & greater trochanter

Question 7

labrum

1) what is it made of
2) function

Answer 7

1) fibro-cartilage (deepens the cavity of acetabulum)

2) tight fit on head of femur, improves congruency, covered by synovial membrane

Question 8

close packed position

1) state of ligaments
2) what actions does it ‘check’

Answer 8

1) taut

2) extension, adduction &medial rotation

Question 9

loose packed position

1) state of ligaments

2 what actions does it ‘check’

Answer 9

1) slack

2) flexion, abduction & lateral rotation
