Does it work?

 

Total hip joint replacement is an orthopaedic success story, enabling hundreds of thousands of people to live fuller, more active lives.

 

Using metal alloys, high-grade plastics, ceramics, and polymeric materials, orthopaedic surgeons can replace a painful, dysfunctional joint with a highly functional, long-lasting prosthesis.

 

Over the past half-century, there have been many advances in the design, construction, and implantation of artificial hip joints, resulting in a high percentage of successful long-term outcomes.

 

Implant Design

 

The hip joint is called a ball-and-socket joint because the spherical head of the thighbone (femur) moves inside the cup-shaped hollow socket (acetabulum) of the pelvis.

 

To duplicate this action, a total hip replacement implant has three parts: the stem, which fits into the femur; the ball, which replaces the spherical head of the femur; and the cup, which replaces the worn out hip socket. Each part comes in various sizes to accommodate various body sizes and types.

 

In modern designs, the stem and ball are modular, allowing for additional customization in fit.

 

Several manufacturers make hip implants. The brand used by your consultant depends on many factors, including your needs (based on your age, weight, bone quality, activity level, and health), consultant experience and familiarity with the device, and the cost and performance record of the implant. These are issues your consultant will discuss with you.
