QUESTIONS AND CORRECT DETAILED ANSWERS
(VERIFIED ANSWERS) |ALREADY GRADED A+
What is incisura? - ANSWER: Spacing in tibia that the fibula sits in
Two tubercles on the anterior tibia where you will find AiTFL - ANSWER: Wagstaffe's
Tubercle
Chaput's Tubercle
What are the three ligaments of the Syndesmosis - ANSWER: AiTFL
PiTFL
Interosseous Membrane
What is a BiMal equivalent ankle fx - ANSWER: Lateral mal fracture with a medial mal
widening
What is a Pilon FX - ANSWER: fracture where the tibal plafond is
interrupted/fractured
What is the tibal plafond - ANSWER: the articular surface of the tibia
Weber Ankle Fracture Classification - ANSWER: A: fibular fx BELOW mortise
B: fibular fx AT LEVEL of mortise
C: fibular fx ABOVE mortise
SER classification/sequence of injury/other system - ANSWER: supination and
external rotation
1. AiTFL
2. Short oblique/spiral fx of distal fib
3. posterior mal
4. medial mal or deltoid
Weber B(ish)
SAD classification/sequence of injury/other system - ANSWER: supination and
adduction
1. distal fib transvers avulsion
2. vertial medial mal
Weber A(ish)
PER classification/sequence of injury/other system - ANSWER: pronation and
external rotation
1. medial mal or deltoid
2. AiTFL or Chaput avulsion
3. proximal oblique or spiral fx of fib
4. posterior mal
, Weber C(ish)/Maisonneuve
PAB classification/sequence of injury/other system - ANSWER: pronation and
abduction
1. medial mal
2. AiTFL or Chaput avulsion
3. Transverse or comminuted fracture of fibula proximal to the plafond
Maisonneuve
What is a Maisonneuve fracture?/Indication - ANSWER: spiral fracture of the
proximal third of the fibula
Indicates syndesmosis injury and possible deltoid injury
SER, SAD, PER, or PAB all indicate - ANSWER: Ankle fracture
PER or PAB indicate - ANSWER: Syndesmosis and/or deltoid injury
SER indicate - ANSWER: lateral or posterolateral plate
Lateral malleolus surgical goal? common challenges? - ANSWER: length and rotation
shortening of the fibula
Syndesmosis surgical goal? common challenges - ANSWER: perfect reduction
comminution complicates reduction
Medial malleolus surgical goal? common challenges? - ANSWER: anatomic joint
surface
tough when fragment is small - medial comminution makes especially hard
what two Surgical approaches are there to a posterior malleolus fx?
what does literature say - ANSWER: Posterior approach: direct reduction/fixation but
incision offers more complication
Anterior approach: indirect reduction/fixation
Use nanoscope to make sure anatomic joint
Literature suggests fixing
Soft tissue issues related to Ankle FX - ANSWER: syndesmosis
deltoid ligament
OCD (osteochondral defect)
Percentage of ankle fractures that are associated with OCD - ANSWER: 70%-80%
(78%)
2018 reported 278,000 ankle fractures and sprains, how many associated with
syndesmosis injury? - ANSWER: 25%
