VERIFIED ACCURATE ANSWERS
What is special about the Fibulock? - ------Answers=---It is a
load sharing device that allows for faster return to weight
bearing
Which fractures are not indicated for this technique? - ------
Answers=---Super proximal Weber C and super distal Weber
A
What is the Weber classification system? - ------Answers=---
A classification system for ankle fractures.
What is a Weber A fracture? - ------Answers=---A fracture
below the syndesmosis, transverse, with intact syndesmosis
and deltoid.
What is a Weber B fracture? - ------Answers=---A fracture at
the level of the syndesmosis, usually spiral, with possible
medial malleolus fracture and syndesmosis problems.
What is a Weber C fracture? - ------Answers=---A fracture
above the syndesmosis, with disrupted syndesmosis and
possible medial malleolus and deltoid injury.
, What is the Lauge-Hansen classification? - ------Answers=--
-A classification system for ankle injuries based on the
mechanism of injury.
What is the most common mechanism of injury in the Lauge-
Hansen classification? - ------Answers=---Supination-
External rotation (SER).
What structures are affected in an SER injury? - ------
Answers=---AITFL, ATFL, spiral/oblique fibular fracture, PiTFL,
posterior malleolar fracture, medial malleolar avulsion
fracture, deep deltoid.
What is the next most common mechanism of injury in the
Lauge-Hansen classification? - ------Answers=---Pronation-
External rotation (PER).
What structures are affected in a PER injury? - ------
Answers=---ATFL, Maisonneuve injury, isolated medial
malleolar fracture, deep deltoid, high spiral/oblique fibular
fracture.
What is the Supination-Adduction (SAD) mechanism of injury?
- ------Answers=---Talofibular sprain or distal fibular
avulsion, vertical medial malleolus fracture.
What is the Pronation-Adduction (PAB) mechanism of injury? -
------Answers=---Isolated medial malleolar fracture, ATFL
