DEX IOT Day 2 ACTUAL Exam Questions
and CORRECT Answers
What is special about the Tightrope XP Drill? - CORRECT ANSWER - Designed to
prevent skiving off the fibula ridge.
What suture is the Tightrope XP Drill loaded with? - CORRECT ANSWER - #5
UHMWPE
What does UHMWPE stand for? - CORRECT ANSWER - Ultra High Molecular Weight
Polyethylene
What is the transmalleolar plane? - CORRECT ANSWER - A plane that is 30 degrees
anterior to the coronal plane.
What should be done before drilling for the XP tightrope - CORRECT ANSWER -
Stabilize all fractures first.
Where should the drilling for the tightrope xp start? - CORRECT ANSWER - About 1.5
cm above the joint line.
What is the size of the drill bit for the tightrope xp? - CORRECT ANSWER - 3.7.
How should the black knob on the tightrope xp be positioned during passing? - CORRECT
ANSWER - Either towards the foot or towards the head. Towards the foot is slightly better.
Why is positioning the black knob for the tightrope xp towards the foot slightly better? -
CORRECT ANSWER - The passer tip is at a 45 degree angle. When the button is towards
the foot the 45 degree angle lines up with the tibia and allows the button to flip without pushing
out into the soft tissues as much
, How is the tightrope XP tensioned? - CORRECT ANSWER - Hold the center of the
sutures and walk the button down to the plate or nail before starting to tension to stop the suture
from bunching
What plates come in the Ankle Fracture system? - CORRECT ANSWER - Locking distal
fibula plates, Locking third tubular, Locking Straight, Medial Hook Plate, Locking Lateral Hook
Plate
What are the features of the Locking distal fibula plates? - CORRECT ANSWER - Only
plate with suture holes that can be used for the AiTFL.
What sizes of screws can be used in the head of the locking distal fibular plates? - CORRECT
ANSWER - 2.7 locking/cortical and 3.0 cancellous.
How many hole options in the distal fibular plate can be used for the syndesmosis tightrope? -
CORRECT ANSWER - 3.
What sizes of screws can be used in the shaft of the distal fibular plate? - CORRECT
ANSWER - 3.5 screws or 4.0 cancellous.
What are the available sizes for the distal fibular plate? - CORRECT ANSWER - 4, 5, 6, 8,
10, 12, 14.
What is the purpose of the tapered distal end of the distal fibular plate? - CORRECT
ANSWER - To limit soft tissue irritation.
What type of screws can be used with the locking third tubular plate? - CORRECT
ANSWER - 3.5 screws or 4.0 cancellous.
What are the benefits of the recessed holes and scalloped edge of the third tubular plate? -
CORRECT ANSWER - They reduce screw prominence and profile, and facilitate
contouring.
