Flexible Flatfoot

Question 1

What are the causes of pes planus?

Answer 1

Biomechanical: FF varus, calcaneal valgus, equinus
Posterior tibial tendonitis: Stage 1 or 2 flexible, 3 or 4 rigid
Tarsal coalition: rigid deformity

Question 2

Where would pain be located with symptomatic pes planus?

Answer 2

along PT tendon, diffuse throughout arch, plantar fascia or achilles insertion

Question 3

What would you expect on a musculoskeletal exam of pes planus?

Answer 3

look for equinus by ankle ROM-caues unlocking of OA of MTJ

look at STJ ROM-in flexible deformity wont be limited

Question 4

What is the Hubscher maneuver and what does it tell you?

Answer 4

passively dorsiflex hallux, plantar fascia tightens aiding in arch rise, heel rise and compression of bones
tests flexibility of deformity
flexible flatfoot: arch rises

Question 5

How can you tell if a patient has a flexible or rigid flatfoot using RCSP and NCSP?

Answer 5

with a flexible deformity with calcaneal valgus present, the NCSP will be less than the RCSP. if rigid, will be same

Question 6

What is the heel rise test used for?

Answer 6

if heel inverts while rising up on toes, flexible deformity. If heel does not move with rising toes, rigid deformity.

Question 7

What findings would you expect with a transverse plane dominance in a flatfoot?

Answer 7

increased kites and increased talocalcaneal angles

Question 8

What findings would you expect with a frontal plane dominance in a flatfoot?

Answer 8

wont see much on x-ray, calcaneal valgus, forefoot varus

Question 9

What findings would you expect with a sagittal plane dominance in a flatfoot?

Answer 9

increased talar declination angle, decreased calcaneal inclination, increased meary’s
