Q

What are the landmarks in Ottawa Ankle Rules and what are the criteria for it?

A

Lateral and medial malleolus, navicular, base of the 5th metatarsal
Pt can or cannot take 4 steps
Weight bearing immediately after injury or not

If any tenderness in 2 or more of the landmarks and they cannot weight bear immediately after injury and cannot take more than 4 steps, this is indicative of a fracture and should be sent for imaging

17
Q

Describe talar tilt test

A

Used to test for injury to lateral ligaments
- PTFL > DF and invert
- CFL > neutral and invert
- ATFL > PF and invert

18
Q

What can compression/squeeze test be used for?

A

High ankle sprain > AITFL and PITFL

19
Q

Name the lateral ligaments

A

Anterior talofibular ligament, posterior talofibular ligament, calcaneofibular ligament

20
Q

What is the origin insertion of the CFL?

A

Origin = lateral malleolus
Insertion = lateral calcaneus

21
Q

What is the origin insertion of the ATFL?

A

Origin = lateral malleolus
Insertion = lateral aspect of talar neck

22
Q

What is the origin insertion of the PTFL?

A

Origin = posterior aspect of distal fibula just posterior to lateral malleolus
Insertion = lateral tubercle of posterior talus

23
Q

What is the deltoid ligament composed of?

A

Tibionavicular ligament, tibicalcaneal ligament, anterior tibiotalar ligament and posterior tibiotalar ligament
Origin of all 4 = medial malleolus

24
Q

What special test is used for deltoid ligament?

A

Kleiger’s test > neutral position then rotate ankle externally
