anterior glide with external rotation

posterior glide with internal rotation

5
Q

what mm cause hip restricted in internal rotation

A

piriformis and iliopsoas spasm

6
Q

what mm cause hip restricted in external rotation

A

spasm of internal rotators

7
Q

when foot is pronated (dorsiflexed and everted) where is fibular head

A

anterior

8
Q

when foot is supinated (plantarflexed and inverted) where is fibular head

A

posterior

9
Q

femoral nerve spinal cord levels and what does it innervate

A

L2-4
quads, iliacus, sartorius and pectineus
sensory anterior thigh and medial leg

10
Q

sciatic nerve levels and what does it innervate

A

L4-S3
tibial portion goes to hamstrings except short head biceps femoris, plantar and toe flexors
sensory lower leg and plantar foot
peroneal goes to short head biceps femoris, evertors and dorsiflexors and extensors of toes
sensory to lower leg and dorsum foot

11

coxa vara

A

hip angle with neck and shaft of femur is

12
Q

coxa valga

A

hip angle with neck and shaft of femur is >135

13
Q

Q angle

A

intersection of line from ASIS through patella

line from tibial tubercle though middle patella

14
Q

increased Q angle

A

genu valgum >12

15
Q

decreased Q angle

A

genu varum

16
Q

what nerve is affected by posterior fibular head

A

common fibular or common peroneal

17
Q

larger Q angle more likely to have what issue

A

patello femoral syndrome

stronger vastis lateralis and weak vastus medialis

18
Q

most likely Q angle in women

A

larger (valgum) because of wider pelvis

19

20
Q

second degree ligament tear

A

partial tear

dec tensile strength with mild-mod laxity

21

third degree ligament tear

A

complete tear, no tensile strength and severe laxity

22
Q

O donahues triad

A

common knee injury with ACL, MCL and medial meniscus injured

23
Q

foot more stable in dorsi or plantar flexion?

A

dorsiflexion because talus is wider anteriorly

24
Q

most ankle sprains occur in what motion

A

plantar flexion because ankle more stable in dorsi

anterior talofibular, calcaneofibular and posterior talofibular

33
Q

medial stabilizer of ankle
