Management Of Ankle Sprains (2) Flashcards
Where is a lateral ankle sprain least stable?
Loose packed
What is the position of a lateral ankle sprain?
Plantarflexion with inversion
Why are medial ankle sprains less common?
Due to decreased eversion ROM and bony architecture
What are the rarest type of ankle sprain?
Syndesmotic (high) ankle sprains
How do lateral ankle sprains progress?
From ATFL to CFL to PTFL
What are some symptoms in a grade 1 lateral ankle sprain?

Involves ATFL and CFL
What is recovery time for a grade 2 lateral ankle sprain?
10-30 days
Where are grade 2 lateral ankle sprains most commonly seen?
Physical therapy
What is a grade 3 lateral ankle sprain?

What is the recovery time for a grade 3 lateral ankle sprain?
30-90 days
Where is a grade 3 lateral ankle sprain most commonly seen?
Ortho first
What does the anterior draw test for?
ATFL
When does the anterior drawer test have the best diagnostic accuracy?

What percentage of ankle sprains are medial/eversion?
5-10%
What does a medial ankle sprain have potential for?
Mortise instability and medial malleolar fracture
What is a syndesmotic (high) ankle sprain?
Injury to anterior tibio fibular ligament (rotation and plantar flexion)
What is the recovery time for a syndesmotic (high) ankle sprain?
> 6 months (possible surgery)

Recurrent ankle sprains
What does chronic ankle instability feel like?
Giving way
What is associated with chronic ankle instability?
Repeated ankle sprains
Persistent weakness
Pain during activity
What are the two primary components of chronic ankle instability?
Mechanical instability and functional instability
What has no effect on treatment of acute ankle injuries?
Ultrasound, laser therapy, and electrotherapy
