Ankle: Anatomy 5 Flashcards
(42 cards)
Flat foot postures (or pes planus) generally fall into two categories. What are they?
- supple flat foot
- rigid flat foot
What is a supple flat foot?
arch collapses during WB activities but is present when unloaded
What is a rigid flat foot?
Arch is absent in both WB and unloaded positions

Retroversion
Pes cavus: Related factors
bony
- Decreased calcaneal eversion

Pes cavus: Related factors
Muscular imbalance with stronger (what group)
Subtalar joint invertors
