Inside lg't of the head of the femur?

Back 6

= Ligamentum teres,

pelvis -> fovea capitis

inside: a. of the head of the femur

Back 8

Front 9

Where are vv.'s & n.?

Back 9

Superior gluteal vv.'s & n. travel between gluteus minimus (deep) & medius.

Front 10

External rotation of the hip m.'s

Back 10

Obturator internus + gemelli

Quadratus femoris m.

Piriformis m.

Gluteus maximus m.

Front 11

Internal rotation of the hip m.'s

Back 11

Gluteus medius & minimus mm;

TFL (tensor fasciae latae)

Front 12

Balance m.' of the hip

Back 12

Gluteus maximus (by tensing the iliotibial tract)

TFL* m. (by tensing the iliotibial tract)

Abductor mm. (gluteus medius & minimus)

Front 13

Testing strength of hip m.'s

Back 13

Trendelenburg test

Tests strength of gluteus medius/minumus m.'s & stability of the hip joint

test is + contralaterally when the pelvis drops on the side where the foot is lifted from the floor

Front 14

Posterior thigh m.'s

Back 14

Hamstrings

Medial: Semimebranosus, Semitendinosus

Lateral: Biceps femoris (long & short head)

Most: O = ischial tuberosity; N = tibial n.

BFSH: N = common fibular n.

Front 15

Iliotibial band syndrome

Back 15

Iliotibial band passes over

lateral femoral condyle

Can be irritated by repeated flexion of the knee.

Front 20

Anatomic variation of

Sciatic n.

Back 20

Tibial division - always inferior to piriformis m.

Fibular division - wrt/ piriformis m.:

87% inferior

12% through

1% superior

Front 21

Intramuscular injection

Back 21

Must avoid superior gluteal & sciatic n.'s

-> inject in the upper right quadrant of the gluteal region

Front 22

Blood supply of the posterior thigh

Back 22

Perforating branches from deep femoral a.

-> penetrate the insertion of adductor magnus

- anastosmosis w/ branches of

medial & lateral femoral circumflex vv.'s

& inferior gluteal vv.'s

= cruciate anastosmosis

Front 23

Innervation of the gluteal area & posterior thigh

Back 23

Upper sacral n. roots

Front 24

Back 24

Medial & lateral femoral circumflex a.'s

= branches of deep femoral a.

Front 25

Perthes disease

Back 25

= avascular necrosis of head of the femur due to insufficient blood supply

- Anastosmosis only after closure of the epiphyseal plate
