Hips and Pelvis Flashcards
(44 cards)
what makes up the bony pelvis
coxal bones
sacrum
coccyx
what are coxal bones
ilium
ischium
pubis
acetabulum
obturator foramen
what 3 bones does the acetabulum connect
ilium
pubis
ischium
concave sacrum
anterior/ventral surface
convex sacrum
posterior/dorsal surface
coccyx
-4 fused vertebrae
-base is superior
-apex is inferior
-no nerves
anterior pelvic outlet
ischial tuberosities
ischiopubic rami
pubic symphysis
posterior pelvic outlet
sacrotuberous ligament
sacrum
coccyx
female pelvis
-wider
-more shallow
-larger opening
-sacrum flattened anteriorly
pubic arch
-angle at anterior inferior pelvis
-female-thumb and index
-male-index and middle
Q-angle
-overall line of force of quadriceps
-wider pelvis increases angle
-increased medial knee stress
fovea
-depression at femur head
-attachment for ligament of head
femur neck
projects superomedially from shaft
hip joint
-synovial articulation between head of femur and acetabulum
-multi axial ball and socket for stability and weight bearing
-flexion, extension, abduction, adduction, medial rot, lateral rot, circumduction
femoroacetabular joint consists of
acetabulum surface and femoral head with hyaline cartilage
acetabular labrum
-deepens the socket
-fibrocartilage
fovea- ligamentum teres
-runs from central of femoral head to inferior rim of acetabulum
-carries small branch of obturator artery
hip joint capsule
-attaches to borders of the articular surfaces of the femur and acetabulum
-forms covering around the ligamentum teres
-reinforced by ligaments
what are the anterior ligaments of the hip joint
-iliofemoral
-pubofemoral
-inguinal
iliofemoral ligament
-Y ligament
-ilium inferior to ASIS to anterior femur
-prevents excessive extension
pubofemoral limagent
-from pubic portion of acetabular ring to anterior femur
prevents excessive abduction
inguinal
-medial ASIS to later pubic tubercle
what is the posterior ligament of the hip joint
-ischiofemoral- from ischial rim to acetabulum to anterior joint capsule and femur, prevents excessive extension
arterial circulation
-right common iliac artery
-left common iliac artery
