ARTHREX DEX 5 DAY
When the surgeon is performing a DIP joint fusion and has inserted the double ended kwire to
the desired depth in the middle phalanx, how many millimeters should be subtracted from the
measured length of the kwire to account for countersinking the screw head and compression at
the fusion site?
1mm
2mm
4mm
None, it is not necessary to account for compression or countersinking the screw head -
ANS4mm
Why is a solid 1.5mm Hex Driver included with the compression FT Screw instrumentation?
To aid in screw removal
To increase torque when inserting the solof compression FT screws
To help countersink screws
To make the set look cool - ANSTo aid in screw removal
Which of the following is NOT a feature or a benefit of the 3.5mm mini compression FT screw?
Variable stepped thread pitch
Improved torque transmission through a hexaglobe recess
Conical shaped outer diameter to gain final compression

(AR-8750S)?

True or False: one of the ways the compression FT screws achieve compression is by having a
large pitch on the leading end and smaller pitch on the trailing end - ANStrue

,There are two main types of headless compression screws available on the market. One is a
"herbert" style screw that has threads at the leading end, a smooth shaft, and threads at the
trailing end or head of the screw. The other type is similar to the Arthrex compression FT screws
that is fully threaded with variable thread pitch to gain compression. True or False. The main
advantage to using a fully threaded screw with variable pitch is to gain purchase along the entire
length of the screw rather than depending on the head of a partially threaded screw to gain and
maintain purchase in just the near cortex - ANSTrue
What are the lengths of the 2.5 micro compression FT screws?
8-14mm by 2mm increments, then 16-34mm by 1mm increments

Besides the actual size of the larger compression FT screws, what is the key design difference
between the 5.0 and 7.0 compression FT screws compared to the smaller compression FT
screws?
Variable threaded pitch
Cannulated
Comes with a profile drill
Are tapered on the outer diameter
Headless design - ANSAre tapered on the outer diameter
True or False: a 3.5 mini compression FT screws schieves a statically significant higher
maximum push-out when compared to an acumed acutrak 2 mini screw and a synthes 3.0mm
Hebert screw. This may lead to a better long term stability and less likely screw backout/ -
