(NOT ON EXAM) Pelvic & Miscellaneous Articulations Flashcards
DO NOT STUDY FOR MIDTERM 2
sacroiliac joint classification
plane, synovial
function of sacroiliac joint
load transfer between spine (shock absorption) and lower extremity (coverts torque)
what limits motion of the sacroiliac joint?
ligaments
supporting ligaments of sacroiliac joint
anterior sacroiliac
posterior sacroiliac
interosseous sacroiliac
location of anterior sacroiliac ligament
anterior thickening of fibrous joint capsule
(thinnest & weakest)
location of posterior sacroiliac ligament
posterior surface of joint
location of interosseous sacroiliac ligament
- deep to posterior sacroiliac ligament
- connects tuberosities of sacrum and ileum
function of interosseous sacroiliac ligament
prevents anterior and posterior displacement of SI joint
(one of strongest ligaments)
name the vertebropelvic ligaments
iliolumbar
sacrospinous
sacrotuberous
vertebropelvic ligaments form what type of joint?
syndesmoses (stabilize SI joint)
what forms the greater and lesser sciatic foramen?
sacrotuberous and sacrospinous ligaments cross
location of pubic symphysis
midline joint between pubis portions of os coxae
function of pubic symphysis
- assist pelvis in absorbing weight of body before forces travel to lower extremities (compressive forces)
- slight movement - can shift & rotate
Costovertebral joint extrinsic ligaments
- radiate ligament (head of rib to body & disc)
- interarticular ligament (interarticular crest to rib)
costotransverse joint extrinsic ligaments
- costotransverse ligament
- lateral costotransverse ligament
- superior costotransverse ligament
