Question 7

external rotators of the hip

Answer 7

piriformis
gemellus superior
obturator internus
gemellus inferior
obturator externus
quadratus femoris
gluteus maximus

Question 8

Piriformis

Answer 8

Sciatic nerve passes inferiorly

Origin- anterior surface of lateral sacrum

Insertion- greater trochanter of femur, along the upper medial surface

Actions- external rotation

Question 9

Gemellus superior

Answer 9

Origin- ischial spine

Insertion- medial aspect of greater trochanter

actions- external rotation

Question 10

Obturator Internus

Answer 10

Origin- ischiopubic ramus, obturator membrane

Insertion- medial aspect of greater trochanter

Actions- external rotation

Question 11

Gemellus inferior

Answer 11

Origin- ischial tuberosity

Insertion- obturator internus tendon

Actions- external rotation

Question 12

Obturator Externus

Answer 12

Origin- obturator membrane and the adjacent surfaces of the pubic body and pubic and ischial rami

Insertion- medial aspect of greater trochanter

Actions- external rotation

Question 13

Quadratus Femoris

Answer 13

Origin- lateral border of ischial tuberosity

Insertion- interotrochanteric crest

Actions- lateral rotation

Question 14

Gluteus Maximus

Answer 14

Origin- posterior surface of the sacrum and coccyx, posterior aspect of the ilium

Insertion- oblique ridge on the lateral surface of the greater trochanter and the IT band of the faciae latae

Location- posterior/lateral, superficial

Action- hip extension (powerful), external rotation, abduction (superior fibers), adduction (inferior fibers)

Question 15

Bony landmarks of femur

Answer 15

Proximal end

• head
• femoral neck
• greater trochanter
• lesser trochanter

Shaft
-linea aspera (posterior side)

Distal end

• medial and lateral condyles
• patellar surface

Question 16

Hip internal rotation agonists

Answer 16

• gluteus minimus
• gluteus medius
• tensor fasciae latae

Question 17

Gluteus minimus

Answer 17

Origin- lateral surface of the ilium

Insertion- superior and anterior aspect of the greater trochanter

Location- lateral

Action- hip abduction, internal rotation (weak), hip flexion (weak)

Question 18

Gluteus Medius

Answer 18

Origin - lateral surface of the ilium, just below the crest

Insertion- posterior and middle surface of the greater trochanter

Location- lateral

Action- hip abduction, anterior fibers: internal rotation and hip flexion (weak), posterior fibers: external fibers, hip extension

Question 19

Tensor Fasciae Latae

Answer 19

Origin- anterior aspect of the lateral surface of the iliac crest and ASIS

Insertion- IT band to the lateral tubercle of the tibia

Location- lateral

Action- hip flexion, hip abduction, internal rotation (weak)

Question 20

Iliotibial band

Answer 20

Combination of gluteus maximus and TFL

Crosses the knee (lateral femoral condyle)

Moves during flexion and extension (knee)

Palpate- above femoral lateral condyle

Question 21

IT band syndrome

Answer 21

Most common cause of lateral knee pain
-recurrent friction

Common in runners
-high mileage, track (turning one way constantly or on crowned surfaces)

Common symptoms: pain over the outside of the knee joint, swelling at the location of discomfort, a snapping or popping sensation as the knee is bent
