HIGH YIELD REARFOOT VARUS

Question 1

What is a rearfoot varus?

Answer 1

-the vertical bisection of the calcaneus is INVERTED relative to the ground when the STJ is places in neutral position with the patient in angle base of gait

Question 2

What makes up NCSP?

Answer 2

• STJ in neutral

- frontal plane leg deviation

Question 3

What are possibilities that may cause rearfoot varus?

Answer 3

• the calcaneus not changing form a varus torsion shape
• the thickness of the talus
• tibial epiphysis varus
• tibial varum

Question 4

What is the normal structural shape of the calcaneus in early uterine development

Answer 4

-varus torsion of the calcaneus

Question 5

When should a child outgrow this varus torsion?

Answer 5

-by the time they walk or shortly after (12-18 months)

Question 6

T/F The talus is thinner dorsally medial.

Answer 6

-false (thicker dorsal medial)

Question 7

What will till the talus and calcaneus into varus when placed in neutral?

Answer 7

-the fact tat the talus is thicker dorsal medial

Question 8

What is the unequal growth of the distal tibial epiphysis?

Answer 8

-tibial epiphysis varus (is an growth abnormality)

Question 9

What tilts the calcaeus, ankle joint, and STJ into inversion?

Answer 9

-the lateral side of the tibial is thicker than the medial side

Question 10

What four main areas can tibial varum occur?

Answer 10

• curvature of the whole tibia
• genu varum (driven by coxa valgus)
• curvature of the distal 1/3 of tibial shaft
• Blount’s disease
