Final Answer:
The step drill sleeve for the FlipCutter should be tapped into the femur approximately 20mm before reaming the ACL. Thus, the correct answer is D. 20mm.
Step-by-step explanation:
In orthopedic procedures like anterior cruciate ligament (ACL) reconstruction, precision in instrumentation is crucial for successful outcomes. The FlipCutter is a tool used during ACL surgery, and the step drill sleeve is an integral part of this instrument. This sleeve guides the FlipCutter to create a socket in the femur for ACL reconstruction. The appropriate depth to tap the step drill sleeve into the femur before reaming the ACL is around 20mm.
The 20mm depth signifies the insertion distance required to position the step drill sleeve properly within the femur before reaming for the ACL socket. This depth ensures that the FlipCutter functions optimally by guiding the tool at the correct angle and depth necessary to create the socket in the femur for ACL reconstruction. Precise placement of the step drill sleeve is critical to avoid complications and achieve accurate ACL reconstruction.
Orthopedic surgeons follow specific guidelines and measurements to ensure the correct placement of instruments during ACL surgery. The 20mm depth for tapping the step drill sleeve into the femur is a standardized measurement established based on anatomical considerations and surgical expertise to achieve accurate and successful ACL reconstruction procedures. Therefore, adhering to this measurement guideline is essential for the effectiveness and safety of the surgical process.
Thus, the correct answer is D. 20mm.
