What is special about the Tightrope XP Drill? - (answers)Designed to prevent
skiving off the fibula ridge.
What suture is the Tightrope XP Drill loaded with? - (answers)#5 UHMWPE
What does UHMWPE stand for? - (answers)Ultra High Molecular Weight
Polyethylene
What is the transmalleolar plane? - (answers)A plane that is 30 degrees anterior
to the coronal plane.
What should be done before drilling for the XP tightrope - (answers)Stabilize all
fractures first.
Where should the drilling for the tightrope xp start? - (answers)About 1.5 cm
above the joint line.
What is the size of the drill bit for the tightrope xp? - (answers)3.7.
How should the black knob on the tightrope xp be positioned during passing? -
(answers)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? - (answers)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? - (answers)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? - (answers)Locking distal fibula
, 2|Page
plates, Locking third tubular, Locking Straight, Medial Hook Plate, Locking Lateral
Hook Plate
What are the features of the Locking distal fibula plates? - (answers)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? -
(answers)2.7 locking/cortical and 3.0 cancellous.
How many hole options in the distal fibular plate can be used for the syndesmosis
tightrope? - (answers)3.
What sizes of screws can be used in the shaft of the distal fibular plate? -
(answers)3.5 screws or 4.0 cancellous.
What are the available sizes for the distal fibular plate? - (answers)4, 5, 6, 8, 10,
12, 14.
What is the purpose of the tapered distal end of the distal fibular plate? -
(answers)To limit soft tissue irritation.
What type of screws can be used with the locking third tubular plate? -
(answers)3.5 screws or 4.0 cancellous.
What are the benefits of the recessed holes and scalloped edge of the third
tubular plate? - (answers)They reduce screw prominence and profile, and
facilitate contouring.
What is the thickness of the locking third tubular plate? - (answers)1.2 mm.
Which holes in the third tubular plate can be used for syndesmosis. - (answers)All
What are the available hole options for the locking straight plate? - (answers)4, 6,
7, 8, 10, 12.
What times of fractures are third tubular plates usually used for - (answers)Distal
fibular fractures
