1

what is the acetabulum labrum

fibrocartilaginous rim along the margin of the acetabulum

2

what shape if the iliofemoral ligament

Y (upside down)

3

name the 3 ligaments of the hip joint

iliofemoral, ischiofemoral (posterior) and pubofemoral

4

what muscles are flexors of the hip

iliopsoas
sartorius
tensor fascia latae
rectus femoris
pectineus
adductor longus
adductor brevis
anterior adductor magnus
gracilis

5

what muscles are adductors of the hip

adductor longus
adductor brevis
adductor magnus
gracilis
pectineus
obturator externus

6

what muscles are lateral rotators of the hip

obturator externus
obturator internus
gemeli
prirformis
quadratus femoris
gluteus maximus

7

what muscles are extensors of the hip

hamstrings (semitendinous, semimembranosus, biceps femoris)
posterior adductor magus
gluteus maximus

8

what muscles are abductors of the hip

gluteus minimus
gluteus medius
tensor fascia latae

9

what muscles are medial rotators of the hip

anterior gluteus medius
anterior gluteus minimus
tensor fascia latae

10

what typically causes a posterior hip dislocation

a traumatic event in which the hip is flexed, adducted and medially rotated

11

at what level does the sciatic nerve run posterior to the acetabulum

ischium

12

what division of the sciatic nerve is most commonly affected in posterior hip dislocation

common fibular nerve

13

what is Trendelenburg's Sign

inferior 'dropping' if the contralateral hip when standing on one leg due to dysfunctional hip abduction

14

what causes Trendelenburg's Sign

dysfunctional hip abduction due to muscle weakness or paralysis

15

how do femoral shaft fractures become displaced

muscle contraction

16

what does femoral shaft displacement cause

rotation +/or shortening
sharp fragments may injure nearby structures

17

what is a Maisonneuve fracture

separation of the distal tibia and fibula rupture the tibiofibular syndesmosis
proximal fibular fracture

18

name the 5 ligaments of the ankle

anterior tibiotalar ligament
posterior tibiotalar ligament
tibilias posterior
tibionavicular ligament
tibioclacaneal ligament

19

potential neural complication of the anterior compartment of the leg

deep fibular nerve
loss of dorsiflexion

20

potential neural complication of the lateral compartment of the leg

superficial fibular nerve
loss of eversion

21

potential neural complication of the cutaneous innervation of the foot

loss of dorsal foot and lateral 3.5 digits and medial 0.5 big toe sensation - superficial fibular nerve
loss if lateral 0.5 big toe and medial 0.5 second toe sensation - deep fibular nerve

22

what may cause foot drop

dysfunction of anterior compartment musculature

23

what can be caused by foot drop

changes in gait
foot slap and high stoppage
