Gluteal Region and Hip joint

Question 1

Name the two angles of the femur

Answer 1

Angle of inclination

Angle of antevesion (torsion)

Question 2

Muscles of gluteal region - Lateral rotators of hip

Answer 2

Gluteus Maximus (extensor)
Piriformis 
Obturator internus 
Gemelli 
Quadratus femoris

Question 3

Muscles of gluteal region - Medial rotators and abductors of hip

Answer 3

Gluteus Medius

Gluteus Minimus

Question 4

Muscles of Gluteal region for support

Answer 4

Tensor fasciae latae

Question 5

Gluteus Maximus

Answer 5

sacrum, S/T ligament and ilium behind posterior gluteal line > iliotibial tract (3/4) and gluteal tuberosity of femur (1/4)

Extends hip; assists lateral rotation

Inferior gluteal nerve (L5, S1, 2)

Question 6

Tensor Fasciae Latae

Answer 6

Anterior iliac crest and ASIS > iliotibial tract

Tenses fasciae latae and iliotibial tract; supports femur on tibia during standing

Superior Gluteal nerve
- (L4, 5, S1)

Question 7

Gluteus Medius

Answer 7

Ilium between posterior and anterior gluteal lines > greater trochanter of femur (lateral surface)

Abducts and medially rotates hip

Superior gluteal nerve
(L4, 5, S1)

Question 8

Gluteus Minimus

Answer 8

Ilium between anterior and inferior gluteal lines >Greater trochanter of femur(anterior surface)

Abducts and medially rotates hip

Superior gluteal nerve
(L4, 5, S1)

Question 9

Piriformis

Answer 9

Anterior Sacrum and S/T lig. >Greater Trochanter of femur (superior border)
Passes through greater sciatic foramen

Laterally rotates hip

Anterior rami of S1, 2

Question 10

Obturator internus

Answer 10

Pelvic surface of Obturator mem. and surrounding bones
Medial side of Greater trochanter (Trochanteric Fossa)
Passes through lesser sciatic foramen

Laterally rotates hip

Nerve to obturator internus (L5, S1)

Question 11

Gemelli

Answer 11

Superior: Ischial spine
Inferior: Ischial tuberosity
Blend with tendon of Obturator internus

Laterally rotate hip

Superior: Nerve to obturator internus
Inferior: Nerve to quadratus femoris

Question 12

Quadratus Femoris

Answer 12

Ischial tuberosity > Quadrate tubercle on intertrochanteric crest of femur

Laterally rotates hip

Nerve to quadratus femoris (L5,S1)

Question 13

Obturator externus

Answer 13

Outer surface of obturator membrane > Trochanteric fossa

Laterally rotates hip

Obturator nerve -L3,4

Question 14

Sciatic nerve

Answer 14

l4, 5, S1, 2, 3

Tibial leaves below piriformis
Common Peroneal may leave below, above or through piriformis

Question 15

Posterior cutaneous nerve of thigh

Answer 15

Lies on posterior aspect of sciatic nerve
-(S1, 2, 3)

Inferior clunial nerves to skin of inferior half of buttock

Question 16

Cutaneous Nerves –

superior clunial

Answer 16

posterior rami L1, 2, 3

Question 17

Cutaneous Nerves – Middle clunial

Answer 17
