Designed to mimic the ball-and-socket action of your hip joint. During the replacement, the surgeon removes the diseased parts and inserts this artificial joint. What is this called?

• A. Hip Replacement
• B. Pelvic Implant
• C. Hip Prosthesis
• D. Femoral Device

Answer: (C)

The main idea here is naming the artificial joint that’s implanted to replace the hip. The artificial joint used in hip replacement is a hip prosthesis. It’s the device that takes the place of the diseased hip, designed to mimic the ball-and-socket motion of a normal hip. In the procedure, the surgeon removes the damaged parts and inserts this prosthesis so the joint can move smoothly and bear weight.

Think of it like replacing a worn-out joint component with a manufactured part. The term hip replacement refers to the surgery itself, not the implanted device. A pelvic implant isn’t a standard term for this joint, and a femoral device implies only part of the hip’s components rather than the complete joint replacement.
