Q

if you see signs of trauma in one of these joints in the xray images what else do you want to check for and why

A

look for dislocation/fracture in other pelvic bones and joints as the pelvis is a ring structure and always fail in 2 places

22
Q

why is the rectouterine pouch/of douglas clinically relevant

A

as it is the most dependent part of the abdomen when erect this is where things will gather such as fluid (blood/pus etc) or metastases/endometriosis cast offs etc

it is therefore an important area to check

Q

is the prostate more or less dense than the bladder and why

Q

what structures are associated with the posterior aspect of the bladder

3 things

A

ureters and the seminal vesicles and vas deferens

31
Q

why would the ureter be of importance

A

assessing for kidney stone

32
Q

above the pelvic inlet and nestled in the iliac bones are what organs

A

small and large bowels

33
Q

what part of the large bowel is nestled close to the right iliac fossae

A

caecum/appendix

34
Q

what part of the large bowel is nestled close to the left iliac fossae

A

sigmoid colon

35
Q

the descending and ascending colon are between what 2 structures

A

between pelvic bones and ribs

36
Q

the rectum begins at what vertebral level

A

S3 vertebral level

37
Q

what is above the S3 vertebral level

A

sigmoid colon

38
Q

what joint does the head of femur and acetabulum form

A

multiaxial synovial joint

39
Q

do you expect to see the head and greater trochanter of the femur in the same axial slice

A

yes

superiorly we just see head but there is plenty of overlap more inferiorly

40
Q

what 2 large muscles insert onto the greater trochanter

A

gluteus medius and minimus

41
Q

what part of the pelvis do the gluteus med and min originate from

A

lateral and gluteal surface of ilium

42
Q

what path do the psoas major and iliacus muscles take relative to the hip joint and what do they do at the insertion

A

pass anterior to hip joint and form common tendon on lesser trochanter

43
Q

where do the psoas major and iliacus insert

A

lesser trochanter

44
Q

how do you describe the appearance of the psoas maj muscle on a axial cross section

A

more circular

45
Q

how do you describe the appearance of the iliacus muscle on a axial cross section

A

longer, thinner and flatter

46
Q

what does the foramen look like on cross section

A

space between 2 bits of bone

filled with muscles and neurovascular stuff

47
Q

what pelvic muscle passes through the GSF

A

piriformis

48
Q

what neurovascular structure lies anterior to the piriformis

A

sacral plexus

49
Q

the obturator internus fills what aspect of the which foramen

A

inner aspect of obturator foramen

50
Q

where does the obturator internus pass out

A

LSF

51
Q

what is the path of the obturator internus around the ischium

A

90 degree bend around the ischium

52
Q

where does the obturator internus insert

A

femur

53
Q

at what vertebral level does the abdominal aorta bifurcate

A

L4

54
Q

what does the abdominal aorta bifurcate into

A

2 common iliac arteries

55
Q

at what vertebral level does the IVC bifurcate

A

L5

56
Q

what 2 vessels forms the IVC

A

common iliac veins

57
Q

what is the relationship of the common iliac veins to the common iliac arteries

A

veins run medial to arteries but cross underneath - inferior

58
Q

what is the issue of the relationship of the common iliac vein and arteries relationship

A

compression or obstruction

eg aneurysm or pregnancy

59
Q

what do the common iliacs divide into

A

internal and external iliac vessesl

60
Q

at the bifurcation of the common iliacs into the int and ext what structure will you find anterior to this point

A

ureter cross anterior to bifurcation of common iliac arteries

61
Q

what skeletal landmark helps estimate the bifurcation of the common iliac vessels

A

anterior SIJ

62
Q

what muscles do the external iliac vessels run anterior to

A

psoas major

63
Q

the external iliac vessels are called what vessels after it passes under what structure

A

under inguinal ligament

femoral vessels

64
Q

what is the femoral vessels joined by

A

femoral nerve

65
Q

what is the order of structures from lateral to medial in the femoral triangle

A

nerve, artery, vein

66
Q

what does the sacral plexus arise from in terms of nerve roots

A

L4-S4 of spinal cord

67
Q

where do the sacral nerve roots contributing to the sacral plexus emerge from specifically

A

anterior sacral foramina

68
Q

can you see all of the sacral nerve roots in one coronal plane

A

no as there is angulation of the sacrum posteriorly

69
Q

the sacral plexus forms anteriorly to which muscle

A

piriformis

70
Q

which space does the piriformis and the terminal branches of the sacral plexus exit the pelvis cavity

A

GSF

71
Q

the sciatic nerve supplies what parts of the leg

A

posterior thigh and everything below the knee joint

72
Q

what is the relation of the sciatic nerve to the hip joint

A

posterior relation

73
Q

how can the sciatic nerve be compromised as it exits the pelvis

A

space occupying lesion in GSF can cause compression of nerve (eg inflammation of piriformis or tumor)

anatomical variation (eg nerve travels through piriformis and not under it)

pelvic fracture around GSF/SIJ
