Research
Representation
2. What is complication rate percentage of every added 15 minutes in the OR?

Tibialis Neurovascular Bundle
4. What is the nerve on the medial side of the ankle? - ANSWER ✔ Saphenous
Nerve
5. What is the benefit of the XP drill? - ANSWER ✔ Torchar tip that prevents
skiving off the fibular ridge
6. What suture is on the tightrope? - ANSWER ✔ #5 UHMWPE (Ultra-High
Molecular Weight Poly-Ethylene)
,7. What is the size of the oblong button on the tightrope? - ANSWER ✔ 3.5 x
13
8. What size drill is used for the tightrope? - ANSWER ✔ 3.7
9. What is the size of the round button on the tightrope? - ANSWER ✔ 6.5
10.How many cortices should you contact while drilling for tightrope? -
ANSWER ✔ 4 (bi-cortically through fibula and tibia)
11.What percentages of Ankle Fx's have talus OCD? - ANSWER ✔ 70-80%
12.What is special about the Tightrope XP Drill? - ANSWER ✔ Designed to
prevent skiving off the fibula ridge.
13.What suture is the Tightrope XP Drill loaded with? - ANSWER ✔ #5
UHMWPE
14.What does UHMWPE stand for? - ANSWER ✔ Ultra High Molecular
Weight Polyethylene
15.What is the transmalleolar plane? - ANSWER ✔ A plane that is 30 degrees
anterior to the coronal plane.
16.What should be done before drilling for the XP tightrope - ANSWER ✔
Stabilize all fractures first.
,17.Where should the drilling for the tightrope xp start? - ANSWER ✔ About
1.5 cm above the joint line.
18.What is the size of the drill bit for the tightrope xp? - ANSWER ✔ 3.7.
19.How should the black knob on the tightrope xp be positioned during
passing? - ANSWER ✔ Either towards the foot or towards the head.
Towards the foot is slightly better.
20.Why is positioning the black knob for the tightrope xp towards the foot
slightly better? - 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
21.How is the tightrope XP tensioned? - 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
22.What plates come in the Ankle Fracture system? - ANSWER ✔ Locking
distal fibula plates, Locking third tubular, Locking Straight, Medial Hook
Plate, Locking Lateral Hook Plate
23.What are the features of the Locking distal fibula plates? - ANSWER ✔
Only plate with suture holes that can be used for the AiTFL.
24.What sizes of screws can be used in the head of the locking distal fibular
plates? - ANSWER ✔ 2.7 locking/cortical and 3.0 cancellous.
, 25.How many hole options in the distal fibular plate can be used for the
syndesmosis tightrope? - ANSWER ✔ 3.
26.What sizes of screws can be used in the shaft of the distal fibular plate? -
ANSWER ✔ 3.5 screws or 4.0 cancellous.
27.What are the available sizes for the distal fibular plate? - ANSWER ✔ 4, 5,
6, 8, 10, 12, 14.
28.What is the purpose of the tapered distal end of the distal fibular plate? -
ANSWER ✔ To limit soft tissue irritation.
29.What type of screws can be used with the locking third tubular plate? -
ANSWER ✔ 3.5 screws or 4.0 cancellous.
30.What are the benefits of the recessed holes and scalloped edge of the third
tubular plate? - ANSWER ✔ They reduce screw prominence and profile,
and facilitate contouring.
31.What is the thickness of the locking third tubular plate? - ANSWER ✔ 1.2
mm.
32.Which holes in the third tubular plate can be used for syndesmosis. -
ANSWER ✔ All
33.What are the available hole options for the locking straight plate? -
ANSWER ✔ 4, 6, 7, 8, 10, 12.
