Answer 2

pelvis

Question 3

innominate is made up of what bones

Answer 3

ilium
pubis
ischium

Question 4

landmarks of the anterior pelvis

Answer 4

iliac crest
ASIS
AIIS
ischial tuberosity
pubic symphysis

Question 5

landmarks of posterior pelvis

Answer 5

PSIS
PIIS
Inferior lateral angle (ILA) of sacrum

Question 6

joints of the pelvis (3)

Answer 6

sacroiliac
acetabulum
pubic symphysis

Question 7

bone to bone ligaments are called _____ ligaments

Answer 7

true

Question 8

ligaments that attach to another ligament are called _____ ligaments

Answer 8

accessory

Question 9

ligaments of the anterior pelvis

Answer 9

sacrospinous (sacrum to spine of the ischium)
iliolumbar (ilia to 5th lumbar vertebrae)
anterior sacroiliac ligament (covers much of SI joint)
Inguinal l - ASIS to superior pubic rami

Question 10

ligaments of the posterior pelvis

Answer 10

sacrotuberous (sacrum to ischial tuberosity)

posterior sacroiliac ligament (covers SI joint)

Question 11

ligament from ischial spine to lateral margins of sacrum where it blends with sacrotuberous ligament
forms part of the origin from which coccygeus muscles arise

Answer 11

sacrospinous ligament

Question 12

ligament that runs from lower sacral tubercles to ischial tuberosity
gluteus maximus attachment
tendon of the biceps femoris attachement
connects with fascia fo the pelvis

Answer 12

sacrotuberous ligament

Question 13

ligament that participates in stabilization of L5 against anterior and rotary motion
blends with upper part of anterior SI ligament

Answer 13

iliolumbar ligament

Question 14

ligaments of the pubic symphysis

Answer 14

superior pubic ligament

inferior pubic ligament

Question 15

during heel strike, what does the innominate do?

Answer 15

ipsilateral innominate aids leg gliding by ROTATING POSTERIORLY caused by iliopsoas contraction and motion of swing phase
contralateral innominate rotates anteriorly

Question 16

during toe off, what does the innominate do?

Answer 16

ipsilateral innominate passively ROTATES ANTERIORLY

iliospoas relaxes, gluteus maximus and hamstring contract

Question 17

iliacus, psoas and to a lesser extent rectus femoris and sartorius do what function at the hip

Answer 17

hip flexors

Question 18

gluteus maximus and the hamstrings perform what function at the hip?

Answer 18

hip extensors

Question 19

describe the standing flexion test

Answer 19

patient standing
physician contact inferior aspect of PSIS
patient bends forward with hands on toes, knees straight
note motion at PSIS
+ test = one PSIS moves farther superiorly
indicates SI joint dysfunction on side that elevates first

Question 20

describe ASIS compression test

Answer 20

patient supine, physician contacts ASIS bilaterally and induces force through each ASIS alternately
+ test = hard end feel/ restriction to motion on one side
indicates SI joint dysfucntion on side of restricted motion

Question 21

if one side of the innominate is rotated anterior, what happens to the ASIS and PSIS on the ipsilateral side

Answer 21

ASIS goes inferior
PSIS goes superior
iliac crest is level
medial malleolus is driven INFERIOR

Question 22

if one side of the innominate is rotated posteriorly, what happens to the ASIS and PSIS on the ipsilateral side

Answer 22

ASIS is superior
PSIS is inferior
medial malleolus is pulled SUPERIOR (short leg)

Question 23

in sheer, the movement of the innominate dictates where the ASIS, PSIS, iliac crest, and medial malleolus go (T/F)

Answer 23

true
