Flashcards in Chapter 8 - Lower Extremity Deck (27):
1

Anterior vs. Posterior glide of the femur (w/ what else)

Anterior = w/ ER of hip
Posterior = w/ IR of hip

2

Hip restricted to IR - muscle spasms (2)

Piriformis spasm
Iliopsoas spasm

3

Hip restricted to ER - muscle spasms (5)

Spasm of gluteus minimus, hamstrings, TFL, adductor magnus, adductor longus

4

Which collateral ligament articulates with a meniscus?

MCL -- w/ medial meniscus

5

Fibular head motion w/ foot motion

Same or opposite as hand/radial head?

Dorsiflexion (pronation) = ANTERIOR glide
Plantarflexion (supination) = POSTERIOR glide

SAME

6

Pronation of ankle

Dorsiflexion, Abduction, Eversion (DEAP)

7

Supination of ankle

Plantarflexion, Adduction, Inversion (PAIS)

8

Innervation of...
- Pectineus
- Long head of biceps femoris
- Short head of biceps femoris

Femoral

Tibial

Fibular

9

Sensory of femoral n

Anterior thigh, medial leg

10

Angulation of head of femur - define

Normal?

Abnormal terms?

Angle between lines along femoral head and femoral shaft

Normal = 120-135 degrees

Under 120 = coxa vara (thigh points in medially)
Over 135 = coxa valga (thigh points out laterally)

11

Q angle - define

Normal?

Abnormal terms?

Angle between femur and tibia

Normal = 10-12 degrees

Under 10 degrees = Genu varum (tibia points inward)
Over 12 degrees = Genu valgum (tibia points outward)

12

Posterior fibular head -- talus dysfunction?

Anterior fibular head -- talus dysfunction?

Internally rotated ( = plantarflexion)

Externally rotated ( = dorsiflexion)

13

Common fibular nerve is disrupted by a ___ dysfunction of the fibular head

POSTERIOR (plantarflexion)

14

Larger Q angle...affect on patella?

Why?

Name of this?

Often in who? Why?

Treatment?

Pulled laterally --> accelerated wearing of posterior surface

Stronger vastus lateralis than vastus medialis

Patello-femoral syndrome

WOMEN - WIDER PELVIS --> LARGER Q ANGLE

Strengthen vastus medialis muscle

15

Ligament sprains in the knee - 3 degrees

1st degree = no tear
2nd degree = partial tear
3rd degree = full tear (surgery required)

16

MC affected compartment in compartment syndrome

Treatment?

Anterior

Ice, MFR -- to increased venous and lymph return
SURGERY if no improvement

17

Terrible triad (O'Donahue's triad)

ACL, MCL, Medial meniscus

18

Is the ankle more stable in dorsiflexion or plantarflexion?

Why?

Dorsiflexion

The talus is wider anteriorly

19

IR and ER of leg while fixed - what joint?

Talocalcaneal (subtalar)

20

Medial arch of the foot - bones
Lateral arch of the foot - bones
Transverse arch of the foot - bones

Talus, navicular, cuneiforms, 1-3 metatarsals
Calcaneus, cuboid, 4-5 metatarsals
Navicular, cuneiforms, cuboid

21

3 MC transverse arch SD's

1. Cuboid medial glide/rotation
2. Navicular lateral glide/rotation
3. 2nd cuneiform inferior/plantar glide

22

Lateral ankle ligaments (anterior to posterior)

ATF
Calcaneofibular
PTF

23

3 types of lateral ligament tears

Type 1 = ATF
Type 2 = ATF and CF
Type 3 = ATF, CF, and PTF

24

Medial ankle ligament

Deltoid ligament

25

2 plantar ligaments of foot

Spring ligament (calceneonavicular) - medial arch
Plantar aponeurosis (fascia) - calcaneus to phalanges

26

Plantar fasciitis - result? (chronic)

Calcification along stress --> heel spur

27

What ligament prevents hyperextension of the knee?

ACL
