What a Hip Replacement Device Is Made Of

A damaged hip joint causing pain and functional impairment is generally managed by hip replacement surgery, medical journals say. A hip implant will be positioned in place of the damaged joint. These implants are available in different designs and are manufactured by various device makers. An example of a hip device is the recalled hip replacement system of DePuy Orthoapaedics.

The hip joint is a ball-and-socket part in which the spherical head of the thighbone moves inside the cup-shaped hollow socket of the pelvis. The materials used in the implant depend on several factors, including the age of the patient, the patient’s level of activity and the surgeon’s preference. If you are considering to have a hip replacement surgery, you may ask your doctor what type of hip replacement prostheses is suitable for your condition.

In the procedure, a lining on the concave part of the hip socket is fitted with the part of the hip prostheses called the acetabular cup. The acetabular cup is fitted in its right place with the use of cement or through friction application.

The component of a hip implant fitted to replace a damaged femur is called the femoral component. The femoral component is then held on its rightful place with cement such as acrylic bone cement or through non-cemented method such through friction, its shape and through a special type of coating that allows bone growth around the device.

The part that is located in the middle of the femoral component and the acetabular cup is called the articular interface. It is actually a simply-designed ball-and-socket joint that mimics the original one. The interface size may vary in sizes such as 28 mm, 32 mm and 36 mm and this is measured by determining the diameter of either the femoral head or that of the acetabular socket.

It has also been stated in some reports showing that those who experienced premature complications due to the hip replacement device tend to have smaller hip cups. Knowing what type of hip device you are using is crucial. The U.S. Food and Drug Administration (FDA) sent DePuy a letter informing it that the government would not approve the ASR XL Acetabular System for use in the United States, even though DePuy sold the device overseas.

Now, the Times reports that in the letter, the FDA questioned the hip replacement metal poisoning data that DePuy sent to the agency. Those who experienced complications from defective DePuy artificial hip implant may check out updates of the DePuy hip recall and learn about the possible steps in filing a DePuy hip replacement lawsuit with the help of an experienced and efficient lawyer if they feel that they are legible to file their respective cases.
