What is the weight of hip total replacement parts?

The weight of hip total replacement parts can vary depending on the materials used and the size of the components. However, a typical total hip replacement (THR) set, including the femoral stem, acetabular cup, and liner, can weigh anywhere from 150 to 350 grams.

The femoral stem, which is the part that replaces the head of the femur (thigh bone), typically weighs between 80 and 150 grams. The acetabular cup, which replaces the hip socket, typically weighs between 50 and 100 grams. And the liner, which is a plastic insert that fits inside the acetabular cup, typically weighs between 20 and 50 grams.

The weight of the THR components is an important consideration during surgery, as it can affect the stability and longevity of the implant. Additionally, the weight of the components may be a factor in determining the type of THR surgery that is best for a particular patient.
