Unit 5 - Lower Limb: Angles (Ex. IV)

Question 1

Where does the angle of inclination go?

Answer 1

head and neck of femur –> shaft of femur

Question 2

Where does the torsion angle go?

Answer 2

head of femur –> neck of femur

Question 3

Where does the Q angle go?

Answer 3

ASIS –> midline through patella

Question 4

What is the relationship between angles?

Answer 4

decreased angle of inclination ==> increased Q angle ==> patella moves L ==> tibial tuberosity more inward ==> femur more diagonal ==> knock-kneed ==> genu valgum

increased angle of inclination ==> decreased Q angle ==> femur more vertical ==> bow-legged ==> genu varum

Question 5

What condition is more common in females?

Answer 5

knock knees from genu valgum (decreased angle of inclination and greater Q angle)

Question 6

How does the patella move during knee flexion?

Answer 6

patella moves down ==> patellar ligament pulled on and tibia moves P

Question 7

How does the patella move during knee extension?

Answer 7

patella moves up ==> pulls on patellar tendon
