Total Hip Arthroplasty (THA) Competency Practice Exam

The correct choice highlights that 60 degrees is not an angle option for the offset reamer handle used in total hip arthroplasty. Understanding the design of the reamer handle is crucial for optimizing surgical technique and ensuring proper alignment and positioning during the procedure.

In total hip arthroplasty, the angles of the reamer handle are specifically chosen to facilitate access and provide precise control while reaming the acetabulum. Common angle options like 135 degrees, 90 degrees, and 45 degrees align well with the anatomical considerations and the mechanics of hip joint preparation. Each of these angles serves a different purpose in terms of accessibility and maneuverability, allowing surgeons to adapt their techniques based on the patient's unique anatomy.

The absence of a 60-degree option in this context suggests that it does not align with the typical requirements or surgical practices for hip arthroplasty, which tend toward the more established angles that correspond with orthopedic standards.
