Arthrex DEX IOT Exam - Questions and Answers When selecting the correct lag screw for the Arthrex Trochanteric Nail, Arthrex recommends typically subtracting 5-10mm from the guide pin measurement, w ... hy? To ensure the ability to lock the lag screw and achieve an acceptable tip-apex distance after intraoperative compression What are the 3 types of proximal femur fractures? 1. Femoral neck 2. Comminuted subtrochanteric 3. Intertrochanteric Which of the following is an appropriate treatment option for a Garden Type 1/2 femoral neck fracture? Hemiarthroplasty What is the significance of the tip/apex distance when inserting an Arthrex Trochanteric Nail? Defines an acceptable position for the location of the lag screw When implanting the Arthrex ES or Long Trochanteric Nail, it is recommended that the surgeon use what size distal reamer? 1mm - 1.5mm above the size of the nail How is the "Tip/Apex Distance" measured? Tip of the lag screw to the apex of the femoral head on AP minus Lateral X-Ray Which Arthrex Trochanteric nail(s) is indicated for use in a subtrochanteric fracture? Long nail only The tip/apex distance should be measured at what distance when inserting an Arthrex Trochanteric nail? 25mm or less What is considered the difference between a stable and unstable femur fractures? Stable fractures resist varus displacement when reduced while unstable fractures fall into varus when reduced What is the purpose of the anti-rotation screw? Provides rotational control of the femoral head and neck During the Arthrex Trochanteric Nail procedure, how can a surgeon use the instruments to ensure the lag screw locking ring is within the nail? Advance the compression sleeve to the targeter and ensure that the surgeon sees the red line Of the three sizes of FT Compression screws, all use a hexalobe/star shaped driver except for _____ which uses a hex driver. 2.5mm How does the Arthrex FT compression screw provide compression? The thread pitch is steeper at the tip of the screw than it is near the driver Advantages of the Arthrex Mini FT and Standard FT Compression screw over the competition include: - More lengths in Mini than Accutrak 2 - Same diameter through length of screw meaning easier change of screw length if needed without losing compression to 'tapered screw' -Hexalobe driver for more insertional torque -Compression achieved with entire length of screw compared to Herbert Screw All of the above What feature does the SynergyRF Bipolar Ablation System have that NONE of the competitors have? Integrates with the Synergy Imaging Platform What is the default ablation setting for the MP50? 4 What is a transverse fracture on the shaft of the 5th metatarsal called? 5th Metatarsal Stress Fracture How many holes does the left and right specific Long 5th Metatarsal Hook Plate have? 7 What nerve is most at risk during percutaneous screw placement for a proximal 5th metatarsal fracture? Sural The following are features of the Arthrex Distal Radius Volar Plate EXCEPT? Avoids FHL tendon disruption Which of the following are the options provided for the size of the Distal Radius Plate? Narrow, Standard, Wide What bone articulates with the distal radius at the radial styloid? Scaphoid The most common type of distal radius fracture is: Colles' What is the normal anatomic volar tilt of the distal radius? 11º T/F: the Wrist Plating System was designed for fixation of intra-articular and extra-articular fractures, osteotomies, as well as nonunions and malunions of the distal radius. True T/F: The Distal Radius Plate is to be placed just distal to the watershed line to minimize tendon irritation False A chronic disruption of the thumb UCL is referred to as? Gamekeeper's thumb [Show More]
