Quiz 4 Flashcards
The pelvis is made up of _ _ bones, the _ _ , and _ joint.
Made of up 2 PELVIC BONES, the PUBIS SYMPHYSIS, and SI joint
SI joints are part _ and part_. The articular surface of the _ is covered with fibrocartilage. The articular surface of the _ is covered with hyaline cartilage that is 3 X thicker than that of _
SI joints are part SYNOVIAL and part SYNDESMOSIS
The articular surface of the ILIUM is covered with fibrocartilage
The “ “ “ “ SACRUM is hyaline cartilage 3 X thicker than than that of the ILIUM.
Resting position of the SI joint? Capsular patter: _ when joints are _. Close pack _ and loose pack _.
Resting position is NEUTRAL
Capsular pattern: PAIN when joints are STRESSED
Close pack: NUTATION
Loose pack: COUNTERNUTATION
The SI joints are supported by the _ _ _ _ that limit anterior pelvic rotation, or _ _.
Are supported by the POSTERIOR SACROILIAC LIGAMENT that limits anterior pelvic rotation or SACRAL COUNTERNUTATION
The _ _ _ ligament limits all pelvic and sacral movement. The _ _ ligament forms part of the sacroiliac articulation (SYNDESMOSIS)
The POSTERIOR SACROILIAC ligament limits all sacral movement.
The POSTERIOR INTEROSSEOUS ligament forms part of the SI articulation (syndesmosis)
The _ ligament and the _ ligament limit nutation and posterior innominate rotation and provides _ _. Aka?
The SACROTUBEROUS ligament and the SACROSPINOUS ligament limit nutation and posterior innominate rotation and provides VERTICAL STABILITY.
AKA: Extrinsic ligaments
The _ ligament stabilizes L5 on the ilium.
The ILIOLUMBAR ligament stabilizes L5 on the ilium
_ _ occurs at the innominate and _ followed by _ occurs with lumbar flexion.
ANTERIOR ROTATION- innominate
NUTATION followed by COUNTERNUTATION- sacrum
With lumbar extension the innominate _ _(slight) and _ occurs at the sacrum
Innominate- POSTERIOR ROTATION (slight)
Sacrum- NUTATION (flexion)
With lumbar rotation _ _ (same side) and _ _ (opposite side) occur at the innominate; _ occurs on the same side in the sacrum.
Innominate
- POSTERIOR ROTATION (same side)
- ANTERIOR ROTATION (opposite side)
Sacrum
-NUTATION occurs on the same side
With Lumbar side flexion _ _ (same side) and _ _ (opposite side) occurs at the innominate. _ _ occurs at the sacrum.
Innominate
- ANTERIOR ROTATION (same side)
- POSTERIOR ROTATION (opposite side)
Sacrum
-SIDE BEND
During hip flexion _ _ occurs at the innominate
POSTERIOR ROTATION
During hip extension _ _ occurs at the innominate
Hip extension ANTERIOR ROTATION occurs . . .
With medial rotation at the hip _ (_ rotation) occurs at the innominate.
INFLARE (MEDIAL rotation)
With lateral rotation at the hip _ (_ rotation) occurs at the innominate
OUTFLARE (LATERAL rotation) occurs at the innominate
