hip Flashcards
1
Q
identify the bones that make up the hip joint
A
- femur
- Ilium
- pubis
- ischium
- maybe sacrum
2
Q
describe movement possible at the hip
A
- flexion
- extension
- abduction
- adduction
- external rotation
- internal rotation
3
Q
explain function of pelvis
A
- supports weight of the body through the spine (force transferred to bones)
- ground reaction forces are transitioned upwards towards spine through locomotion
- site of attachment for muscles
4
Q
movement of the pelvis
A
- posterior tilt
- anterior tilt
- lateral pelvic tilt
5
Q
what does the sacroiliac joint do
A
absorbs weight, force and stress and is very stable
6
Q
what is Trendlenburg Gait
A
frontal plane gait deviation, torso laterally bends towards the weak side
7
Q
describe the 8 difference of the female pelvis
A
- less dense
- wider
- shallower
- has a larger pelvic cavity
- more space
- obturator foramina is more oval shaped
- acetabula is smaller
- pubic arch is greater than 90 degrees
8
Q
Identify the hip articulations
A
- sacroiliac joint
- hip joint
- pubic symphysis
9
Q
identify gluteal muscles at the hip
A
- gluteus maximus
- gluteus medius
- gluteus minimus
- tensor fasciae latae (TFL)
10
Q
identify the 5 anterior hip muscles
A
- Psoas major
- Iliac
- adductor brevis, longs and Magnus
- pectinous
- gracilis
11
Q
identify the main external rotator muscle
A
Piriformis
12
Q
identify the 2 anterior muscles that cross the hip
A
- sartorius
- rectus femoris
13
Q
identify the 3 posterior muscles that cross the hip
A
- semitendinosis
- semimembranosus
- biceps femoris short and long head
14
Q
identify the 6 biarticulate muscles and their roles
A
- gluteus Maximus
- gracilis
- rectus femoris
- semimembranosus
- semitendinosus
- bicep femoris long head
they produce force and contribute to two joint torques at the same time
