hip/pelvic girdle Flashcards
hip joint relatively stable due to
deep ball and socket
large thick capsule
labrum
deepens joint
hip joint functions in
weight bearing and locomotion
hip joint type
ball and socket
hip joint articulation
head of femur connect with acetabulum of pelvic circle
pelvic girdle 3 bones
2 inominates
sacrum
sacrum
extension of spinal column
extending inferiorly from sacrum
coccyx
inominate bone(s)
pelvic bones
pelvic bones divided into 3 areas
upper 2/5 ilium
posterior, lower 2/5 ischium
anterior/lower 1/5 pubic bone
anterior and posterior pelvic rotation AKA
pelvic tilt
anterior and posterior pelvic rotation plane
sagittal
right and left lateral rotation AKA
hip hike and hip drop
hip hike/drop plane
frontal
right transverse and left transverse rotation plane, axis
transverse, longitudinal
hip flexion and extension happens at which joint
acetabulofemoral
hip flexion and extension plane and axis
sagittal, ML
hip abduction and adduction plane and axis
frontal, AP
hip external and internal rotation plane and axis
transverse, longitudinal
symphysis pubis location
anterior
symphysis pubis type
amphiarthrodial
sacroiliac joints location
posterior
sacroiliac type
diarthrodial, synovial plane
in walking, hip flexion and extension occur with pelvic girdle ____, forward in hip ____, and backwards in hip ____
rotation, flexion, extension
pelvis rotation increases
length of stride when running, greater distance and speed to a kick
acetabulofemoral bony architecture provides
stability
acetabulofemoral joint type
ball and socket
synovial
acetabulofemoral ligamentous capsule
thick, stability
acetabulofemoral zone of weakness
femoral neck
femoral neck fracture based on
ground reaction force, gravity, upper body force
iliofemoral or “___” ligament
Y

0-45
__ to __ degrees of adduction
0-20
___ to ___ degrees of internal rotation
0-35
__ to __ degrees of external rotation
0-45
all pelvic girdle rotations results from motion at one or more locations
right, left hip, lumbar spine
low back issues usually comes from
hips
anterior rotation:
lumbar spine motion
right hip motion
left hip motion
extension, flexion, flexion
