A1: anterior and posterior fascia that surrounds QL

A2: anterior superior border of L5 TP

28
Q

what points does the posterior aspect of the iliolumbar ligament attach to?

A

attached to the top of the posterior border of the TP and attached to the ilium behind QL

29
Q

What points does the inferior aspect of the iliolumbar ligament attach to?

A

A1: lower border of the TP of L5

A2:SI ligament (anterior)

FD: Inferior and lateral

30
Q

what two points does the vertical aspect of the iliolumbar ligament attach to?

A

the anterior and inferior border of L5 TP and descends vertically to the iliopectineal line

31
Q

What are the medial and lateral attachments of the sacrospinous ligament? FD?

A

Medial attachment: lateral margin of the lower sacrum and coccyx

Lateral attachment: the spine of the ischium

FD: fibres run transversely laterally

32
Q

what ligament does the sacrospinous ligament blend with?

A

the sacrotuberous ligament

33
Q

list the proximal attachments for the sacrotuberous ligament

A

PSIS, PIIS, lower 1/2 of the dorsal surface of the sacrum, lower 1/2 of the lateral sacral crest, lateral margin of the coccyx and blends partially with the dorsal sacro-iliac ligaments

34
Q

list the fibre direction and distal attachments for the sacrotuberous ligament

A

the fibres run down and laterally to attach distally to the medial margin of the ischial tuberosity

35
Q

the posterior surface of the sacrotuberous ligament attaches to the lowest fibres of which muscle

A

lowest fibres of glute max

36
Q

the lower part of the sacrotuberous ligament continues into what tendon?

A

lower part continues into biceps femoris tendon

37
Q

what pierces the sacrotuberous ligament

A

inferior gluteal artery and perforating cutaneous nerve

38
Q

What aspect of l5 – s1 tells you that it can handle lots of weight?

A

It’s width – remember structure dictates function

39
Q

Why is the SI joint a weight transferal joint?

A

It’s a plane joint that relies on the forces of the muscles to hold it together – transfers the force to the coccyxfemoral joint where the thickest cartilage is, where the strongest ligaments and muscles are

40
Q

If you have OA of the hip on only one side you need to consider…

A

the fact that it is likely disfunction that is causing the issue

41
Q

What type of joint is the symphysis pubis weight bearing or weight transferal?

A

Weight transferal

42
Q

Why is the pelvis not a full bony structure

A

The joints allow movement, and important for pregnancy so the pelvic girdle can open

43
Q

What two muscles support the symphysis pubis?

A

Aponeurosis of the external obliques

Rectus abdominus

44
Q

What creates force closure in the SI joints

A

Lats Glutes

45
Q

What two movements must the SI joint allow for?

A

Side bending

Rotation

46
Q

What is the bony configuration of the SI joint?

A

Essentially 2 blocks that fit together – the wedge shape of the sacrum helps to provide stability and it narrows inferiorly

47
Q

What is one of the most common muscle imbalances you will see?

A

Glutes and Hamstrings

48
Q

What will pain do to muscle in the area?

A

Turn them off – pain inhibition

49
Q

How do you test the integrity of the SI joint?

A

Gapping Splaying Keep in mind when you are gapping and splaying the SI joint that it is so strong there realistically will be little to no movement – if there is there is a big problem

50
Q

The orientation of the dorsal SI ligament is..

A

Vertical

51
Q

If there is tension on the sacrotuberous ligament it will place tension on the __ ligament

A

Dorsal SI ligament

52
Q

How do you test the anterior SI ligament?

Is this test functional?

What is this test called, other than gapping or splaying?

A

Pushing out on the ASIS’s – again realistically should not move at all – so think is this test functional? No, its called a pain provocation test

53
Q

How many bands does the iliolumbar ligament have?

A

5 running off of the TP of L4 and L5 – some authors say just L5

54
Q

What are the directions of the 5 bands of the iliolumbar ligament?

A

Anterior

Posterior

Superior

Inferior

Vertical

55
Q

What movement does the iliolumbar ligament prevent?

What is another function/purpose of the iliolumbar ligament

A

Side bending in L4 and L5

Stabilizes the vertebrae (L4-L5) on the innominate bone

56
Q

If you have disfunction of L4-L5 what also may be in disfunction?

A

The innominate bone – clinical relevance: patient could present with a innominate bone disfunction but cause could be traces back to L4 or L5 stuck in a side bent position placing tension on the iliolumbar ligament and thus placing tension on the innominate

57
Q

The iliolumbar ligament will also help prevent ___ from sliding anteriorly (Extremely significant)

A

L4-L5

58
Q

What is the significance of the sacrospinous ligament with regard to foramen?

A

Converts the greater/lesser sciatic notch into foramen

59
Q

What does the sacrotuberous blend with superiorly?

A

Posterior (dorsal) sacroiliac ligament, also goes into the posterior lamina of the thoracolumbar fascia – significant because it disperses the force (force attenuation) so the force is not focal on any one area

60
Q

What does the sacrotuberous blend with inferiorly?

A

Ischial tuberosity – same attachment point as bicep femoris, so remember you are getting a transfer of forces all the way down the leg

61
Q

What other muscles does the sacrotuberous ligament merge with?

A

Glute max
