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 - ✔️✔️True

having a large pitch on the leading end and smaller pitch on the trailing end - ✔️✔️true
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?

None, it is not necessary to account for compression or countersinking the screw head -
✔️✔️4mm
Why is a solid 1.5mm Hex Driver included with the compression FT Screw
instrumentation?

To help countersink screws
To make the set look cool - ✔️✔️To aid in screw removal
Which of the following is NOT a feature or benefit of the 2.5mm micro compression FT
screw?
Variable stepped thread pitch
Improved torque transmission through a hexalobe recess
Self-tapping flutes
Headless
Cannulated - ✔️✔️Improved torque transmission through a hexalobe recess
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?

Headless design - ✔️✔️Are 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/ - ✔️✔️false
