the pelvis and gluteal region Flashcards
what is the name of the boney structure that can be observed on the proximal head of the femur on the posterior side that projects medially?
lesser trochanter
what is the name of the small ridge of boney bumps found between the greater and lesser trochanter on the anterior side?
intertrochanteric line
what is the name of the small ridge of boney bumps found between the greater and lesser trochanter on the posterior side?
intertrochanteric crest
what is the function of the gluteal tuberosity?
attachement for gluteal muscle
describe the structure of the acetablum
- acetabular labrum deepens the fossa
- lunate surface: articulate with the femoral head
- acetabular fossa: is a deep fossa found inside the acetabulum (think of hot tub)
what is the ligament that closes off the lunate surface?
transverse acetabular ligament
what ligament serves to keep the femoral head inside the acetabulum?
ligament of the head of the femur
onto what does the ligament to head of femur attach to?
fovea
what type of joint is the hip joint?
ball and socket
synovial
multiaxial
what movement is occurs during flexion of the hip joint?
leg advances forward
what type of movement causes the leg to move back (take a step back)
extension about the hip joint
while sitting, if you move your leg outwards what movement is that?
abduction about the hip joint
if sitting with both legs close to one another, what movement is that?
adduction about the hip joint
how could medial rotation about the hip joint be described?
heel of foot points outwards, hence femur rotates internally about hip joint
how could lateral rotation about the hip joint be described?
heel of foot points inwards, femur rotates externally about the hipojoint
what stabilizes the hip joint?
- iliofemoral
- pubofemoral
- ischiofemoral
which stabilizer prevents hyperextension when standing and will limit lateral rotation?
-iliofemoral
which stabilizer prevents over-abduction of the hip joint?
-pubofemoral
which stabilizer limits medial rotation of the hip joint?
-ischiofemoral
what is the most common type of hip dislocation?
posterior hip dislocation
identifying the following dislocation based on symptoms
femur will be shortened, flexed, adducted and medially rotated about the hip joint?
posterior hip dislocation
identifying the following dislocation based on symptoms
femur is slightly flexed, abducted, and laterally rotated about the hip joint
anterior hip dislocation
what A. pierces through the obturator membrane?
obtrurator A
what A. wraps around the front of the femur?
lateral circumflex femoral A.
