Arthrex Minimally Invasive Bunionectomy System

The Arthrex Minimally Invasive Bunionectomy System also includes Beveled FT screws designed specifically for minimally invasive bunion correction. The 45° beveled head provides a zero-profile construct when fully inserted. The Beveled FT screws have a constant thread pitch compared to Compression FT screws as compression may result in tilting of the capital fragment. The Beveled FT screws also have an increased cannulation. This allows for the use of more robust instrumentation. The increased diameter of the guidewires reduces cortical skiving and provides stability throughout the case. The laser-marked guidewires also allow for quick screw measurements from the depth devices used with the system.
 
This simple, effective device helps with initial or secondary K-wire placement for the Beveled FT screws. These radiolucent parallel guides provide two different angles to advance the screw K-wires towards the capital fragment. The angle options are selected based on surgeon entry point preference, patient anatomy, and shift distance of the capital fragment. These guides allow for a percutaneous approach and can be used with the shifting device. The radiolucent material and ease of application assist with fluoroscopic imaging to confirm wire placement throughout the procedure.
