DEX IOT day 2
Which finding is not commonly seen in low-energy pilon fractures? - ANSa. High Comminution -
break or splinter of the bone into two or more fragments due to high energy
b. severe metaphyseal and articular comminution
What is the function of an external fixator device when treating pilon fractures? - ANSa. Stabilize
injury until soft tissue issues (inflammation) are resolved
What size screws are in the two distal rows of the Anterolateral Distal Tibia Plates? - ANSa. 2.7
mm locking and cortical screws
b. Technically 2.7mm KreuLock now
What size screws are in the shaft of the Anterolateral Distal Tibial Plates? - ANSa. 3.5 mm
locking and cortical screws
b. 4.0mm cancellous and 3.5mm KreuLock
What are the Arthrex Distal Tibial Plates and Screws made of? - ANSstainless
Which of the fracture fragments shown in this image represents the Chaput fragment - ANSa.
Chaput's tubercle is the anterolateral side of the tibia
Which of the following is NOT a name of a fracture fragment in a tibial pilon fracture? - ANSi.
Medial malleolar fragment,
ii. Volkmann fragment,
iii. Chaput fragment
When preparing to cover a pilon fracture case, what Orthobiologic product should be on hand
that typically would NOT be used in a standard ankle fracture case? - ANSa. AlloSync
demineralized bone matrix with concentrated BMA
b. The technique guide now has BoneSync on it so maybe this as well
All of the following are plate options found in the Pilon Fracture Distal Tibia Plating System,
EXCEPT: - ANSa. System includes
i. Anterolateral Distal Tibia Plate
ii. Medial Distal Tibia Plate
iii. Posterior Distal Tibia Plate
iv. Anterior Distal Tibia Plate
v. Posterolateral
True or False: An anterolateral distal tibia fragment (Chaput) can be stabilized with the Straight
Plate from the Distal Tibia Plating System. - ANSFalse
, True or False: The 2.7 mm locking kickstand screw in the Medial Distal Tibia Plate supports the
lateral plafond. - ANStrue
True of False: The Anterior Distal Tibia Plate features nine 3.5 mm locking and cortical rafting
screws parallel to the joint surface to support the articular surface of the plafond. - ANSa. False,
it has 7 2.7 mm locking or cortical rafting screws
Which plate included in the Pilon Fracture Distal Tibia Plating System functions as a buttress
plate, aiding in fracture reduction and used to maintain rotational stability. - ANSa. Posterior
Distal Tibia plate
True or False: The Posterolateral Fibula Plate (straight) includes features in the plate to
accommodate the Syndesmosis TightRope® button. - ANSa. False
b. Only the anatomical one has the tightrope feature
Which plate included in the Pilon Fracture Distal Tibia Plating System comes in a straight and
anatomic option? - ANSa. Posterolateral fibula plate
What is the main difference between a fx that is classified as an "ankle fx" and one classified as
a "pilon fx - ANSa. Pilon fx extend into the tibial plafond
b. Intra-articular distal tibia fx (pilon)
The large Combination Clamp found in the ArthroFX™ External Fixation System is designed to
clamp on to all of the following EXCEPT: - ANSa. Clamps onto:
i. 4mm and 5mm Schanz Pins
ii. 6mm Transfixation pins
iii. 11mm Carbon Fiber Rods
True or False: This Multi-Driver Adapter can be loaded on a Universal Chuck w/T-Handle and
used to tighten both 11 mm bolts on Large Combination Clamps as well as all the Schanz and
Transfixation Pins that are included with the ArthroFX™ External Fixation System. - ANStrue
The common general term used to describe the type of external fixation construct applied to the
ankle using the ArthroFX™ External Fixation System is: - ANSdelta frame
Potential advantages for the use of the ArthroFX™ External Fixation System include: - ANSa.
Prevents further damage to soft tissues and allows tissues to begin healing/swelling to attenuate
which leads to improved health of skin and subcutaneous tissues
b. Can be used for provisional fixation OR definitive treatment
c. Minimally invasive which leads to decreased wound complications and allows access to
wounds for debridement and dressing changes
d. Applied rapidly
e. Remote from zone of injury and proposed implant bed
