Pelvis Flashcards
Respiratory axis
S2, superior transverse axis, inhale-counternutates, exhale sacrum nutates
During flexion of the body, sacrum….iliam….
ASIS….. PSIS….
sacrum nutates, iliam outflare (ASIS moves apart and PSIS approximate), tension increases iliolumbar ligaments
most important accessory ligament of pelvis
iliolumbar ligament, from 5th to posterior iliac crest. Multidirectional aspect of the band of this ligament allows the ligaments to check various motion of the L5
Middle transverse axis
normal sacroiliac flexion and extension (2nd sacral body)
Lumbar flexion innominate and sacrum are
innominate: anterior rotation
sacrum: nutation followed by counternutation
Lumbar extension: innominate/sacrum
innominate: Posterior rotation
Sacrum : nutation
Lumbar rotation: innominate and sacrum
Innominate: Same side: posterior rotation, opposite side: anterior rotation
Sacrum Nutation on the same side
Lumbar spine side flexion: innominate and sacrum
Innominate: Same side, anterior rotation, Opposite side: Posteiror rotation
Sacrum: side bend
Hip flexion, innominate is
posteiror rotation
Hip extension innominate is
anterior rotation
Hip medial rotation innominate is
inflare (medial rotation)
Lateral rotation of hip, innominate is
outflare (lateral rotation)
Abduction of hip, innominate is
superior glide
adduction of hip, innominate is
inferior glide
Nutation is limited by which ligament
anterior sacroiliac ligaments, sacrospinous ligament, the sacrotuberous ligament and more stable
Counter nutation is limited by
posterior sacroiliac ligament
Gillet’s test is known for
ipsilateral posterior rotation test
supine to sit test is known as
long sitting tst
Meralgia Paresthetica
entrappment of lateral femoral cutaneous nerve
Ilioinguinal nerve entrapment
hocky player’s syndrome
entrapped with injury to the external oblique muscle aponeurosis
McBurney’s point
1/3 right ASIS to the umbilicus, acute appendicitis
Baer’s point
presence of infection or when there are sprains of the right sacroiliac ligament, located in the right iliac fossa anterior to the right sacroiliac joint slightly medial to McMurney’s point
