Total Hip Arthroplasty (THA) Competency Practice Exam

The choice reflects a specific aspect of surgical planning in total hip arthroplasty, particularly involving the technology used for visualization during the procedure. The cup planning mode refers to software functionality that provides insights into the surgical site and allows for detailed examination of the anatomical structures.

In this context, the reaming view is used specifically to visualize the area of the acetabulum where the bone will be removed to create space for the acetabular component of the hip implant. This unique feature of the cup plan mode enables surgeons to observe the precise contours and structures associated with the bone that is relevant for reaming. The benefit of this visualization is that it helps surgeons to plan their approach more effectively, facilitating better outcomes and reducing the risk of complications by allowing for accurate assessment of the bone that is going to be modified during surgery.

Other types of imaging, such as CT and X-ray, provide important information but may not offer the specialized focus on the bone removal process in the same way that this 3D visualization related to reaming does. Therefore, the focus on 3D visualization in the reaming mode exemplifies the tailored approach that advanced imaging provides in surgical planning for hip arthroplasty.
