Innominate Flashcards
significant structures influence LE circulation and drainage include the _____ diaphragm and _____ area
pelvic diaphragm and inguinal area
the \_\_\_\_\_ maintains a critical role in Biomechanical function/balance/locomotion Reproduction Elimination of waste vascular and lymphatic functions
pelvis
innominate is made up of what bones
ilium
pubis
ischium
landmarks of the anterior pelvis
iliac crest ASIS AIIS ischial tuberosity pubic symphysis
landmarks of posterior pelvis
PSIS
PIIS
Inferior lateral angle (ILA) of sacrum
joints of the pelvis (3)
sacroiliac
acetabulum
pubic symphysis
bone to bone ligaments are called _____ ligaments
true
ligaments that attach to another ligament are called _____ ligaments
accessory
ligaments of the anterior pelvis
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
ligaments of the posterior pelvis
sacrotuberous (sacrum to ischial tuberosity)
posterior sacroiliac ligament (covers SI joint)
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
sacrospinous ligament
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
sacrotuberous ligament
ligament that participates in stabilization of L5 against anterior and rotary motion
blends with upper part of anterior SI ligament
iliolumbar ligament
ligaments of the pubic symphysis
superior pubic ligament
inferior pubic ligament
during heel strike, what does the innominate do?
ipsilateral innominate aids leg gliding by ROTATING POSTERIORLY caused by iliopsoas contraction and motion of swing phase
contralateral innominate rotates anteriorly
during toe off, what does the innominate do?
ipsilateral innominate passively ROTATES ANTERIORLY
iliospoas relaxes, gluteus maximus and hamstring contract
iliacus, psoas and to a lesser extent rectus femoris and sartorius do what function at the hip
hip flexors
gluteus maximus and the hamstrings perform what function at the hip?
hip extensors
describe the standing flexion test
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
describe ASIS compression test
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
if one side of the innominate is rotated anterior, what happens to the ASIS and PSIS on the ipsilateral side
ASIS goes inferior
PSIS goes superior
iliac crest is level
medial malleolus is driven INFERIOR
if one side of the innominate is rotated posteriorly, what happens to the ASIS and PSIS on the ipsilateral side
ASIS is superior
PSIS is inferior
medial malleolus is pulled SUPERIOR (short leg)
in sheer, the movement of the innominate dictates where the ASIS, PSIS, iliac crest, and medial malleolus go (T/F)
true
