hip Flashcards
HIP + PELVIS
3 main joints + what type
1) ACETABULOFEMORAL : ball and socket
2) SACROILIAC : gliding , lock when weight bear
3) PUBIC SYMPHYSIS: slightly moveable

HIP + PELVIS
how many muscles allow external rotation of hip?
where are they located?
6
back of greater trochanter
+ gluteus maximus
HIP + PELVIS
what muscles allow internal rotation of the hip?
no primary muscle , many contribute
HIP + PELVIS
what is Lombard’s paradox?
anatomical differences created torque so net movement in one direction
so don’t get stuck
HIP + PELVIS
femoralacetabular impingement
caused by:
what does it cause:
who’s ar higher risk:
caused by:
- abnormal growth of femur/acetablum
damage cartilage of joint
hip osteoarthiritis
higher risk in young
HIP + PELVIS
iliotibial band syndrome
if tight:
inflammation on lateral side of knee
friction between iliotibial band + lateral condyle of femur
HIP + PELVIS
hamstring strain
risk factors (4)
- prev hamstring strain
- fatigue
- strength imbalance
- poor flexibility
