Review Session Flashcards
What are the Ottawa ankle rules? (4)
- Tenderness of the posterior edge of the lateral malleolus or medial malleolus
- Pain at the base of the 5th metatarsal
- Point tenderness at the navicular
- Inability to bear weight both immediately and in the ED
What imaging would you get if the Ottawa ankle rules are positive?
X rays
Usually pronation or eversion/lateral rotation mechanism. Often a contact injury
Medial ankle sprain/deltoid ligament sprain
This can come along with a medial ankle sprain. Often comes with a contact injury as body IR on a fixed foot.
Maisonneuve fx
This will have a positive anterior drawer in ER, positive lateral tilt test, positive kleiger test
Deltoid ligament sprain
This occurs when you have IR on a fixed dorsiflexed ankle. Will have diffuse pain anterolaterally or posteriormedially about the talocrural joint
High ankle sprain
With this you will have tenderness to palpation of the anterior inferior tibiofibular ligament and syndesmosis, pain with DF. Will have a positive squeeze test.
High ankle sprain
This is diagnosed with the reverse anterolateral drawer test or palpating the talus during the anterior drawer test
Lateral ankle sprain
What are tx for lateral ankle sprains?
Prophylactic bracing, exercise, manual therapy to restore DF, NMR. Maybe NSAIDS, ice, diathermy, laser. NOT US!
This is lateral midfoot pain due to a positional fault. Usually happens with a lateral ankle sprain. Pain with fibularis muscle testing, painful heel raise. How would you treat it?
Cuboid syndrome. Not a lot of research but likely tx with cuboid whip
What does the lisfranc ligament connect?
It connect the medial cuneiform to the second metatarsal
This is caused by ankle/foot supination on an axial loaded forefoot. Fall over fixed forefoot
Lisfranc injury
This will have the gap sign (increased space between 1st and second toes). Swelling, ecchymosis, tenderness. Need to check pulse of dorsalis pedis and 1st webspace sensation. What will be seen on imaging?
Lisfranc injury will show fleck sign in imaging
Will feel a pop in the back of the ankle, can usually feel a divot. Associated with high cholesterol, use of fluoroquinolones, statins, long term glucocorticoids.
Achilles rupture
Can occur with a lateral sprain. Tenderness with palpation at lateral malleolus and pain with resisted PF+eversion
Fibularis tear
This can occur with a lateral ankle sprain and has tenderness to palpation, along with pain with PF+eversion but has reports of popping and snapping. What is injured?
Fibularis subluxation due to a retinacular tear
