Question 17

The Q angle is formed by the intersection of a line from the

Answer 17

ASIS through the middle of the patella and a line from the tibial tubercle through the middle of the patella

Question 18

Answer 18

10-12 degrees

Question 19

An increased Q angle is called

Answer 19

Question 20

A decreased Q angle is called

Answer 20

Genu varum, the patient will appear bowlegged

Question 21

A posterior fibular head or fracture of the fibular may disturb the function of this nerve

Answer 21

Common peroneal nerve

Question 22

Patello-femoral syndrome

Answer 22

Due to an imbalance of the musculature of the quads (strong vastus lateralis and weak vastus medialis).
Related to a larger Q angle.

Question 23

Patello-femoral syndrome in more common in

Answer 23

women because a wider pelvis often results in a larger Q angle

Question 24

First degree sprain

Answer 24

no tear resulting in good tensile strength and no laxity

Question 25

Second degree sprain

Answer 25

partial tear resulting in decreased tensile strength with mild to moderate laxity

Question 26

Third degree sprain

Answer 26

complete tear resulting in no tensile strength and severe laxity, requires surgery

Answer 29

dorsiflexion

Question 30

The lateral stabilizers of the ankle are the

Answer 30

Anterior talofibular ligament
Calcaneofibular ligament
Posterior talofibular ligament
They prevent excessive supination

Answer 31

Anterior Talofibular Ligament

Question 32

The medial stabilizer of the ankle is the

Answer 32

deltoid ligament

Question 33

Excessive pronation of the foot results in

Answer 33

fracture of the medial malleolus instead of pure ligamentous injury

Question 34

Spring Ligament

calcaneonavicular ligament

Answer 34

supports the medial longitudinal arch

Question 35

Plantar Aponeurosis

plantar fascia

Answer 35

chronic inflammation here can lead to calcification and heel spurs
