Hip replacement has helped restore the quality of life for thousands of people. Advances in the design and surgical implantation of artificial joints has made it possible for patients to take part in the activities they enjoy, free from pain and with a fully functioning, long-lasting prosthesis.
A total hip replacement implant has three pieces:
- The stem, which fits into the femur
- The ball, which replaces the head of the femur
- The cup, which replaces the hip socket
These pieces come in varying sizes to fit a wide range of body types. The implant you receive is based on your weight, age, quality of your bone and your overall health.
Most hip implants today are made with titanium or cobalt-based materials. Some have porous surfaces to that bones are able to grow into them. Together, the components of a hip implant weigh around 1 pound depending on the size needed.
All of the materials used in hip implants have several things in common:
- They are able to be used in the body without risk of a rejection response.
- They are just as good as your hip bones; they move against each other smoothly and can withstand loads without breaking.
- They are extremely resistant to wear and tear and corrosion. You can use them for many years.
Hip implants can be cemented, cementless or a combination of the two. This depends on the type of fixation is used to keep the implant in place.
Cemented total hip replacement
With a cemented total hip replacement, you will be able to put your full weight on the limb and walk without support quickly after surgery. Although there is a risk of loosening, the bond between the bone and cement is generally very strong and reliable.
Cementless total hip replacement
Cementless implants attach directly to the bone without the need for cement. Their textured surface also allows new bone to grow directly into the implant.
Cementless implants are generally stable long-term, but they have a risk of loosening if a strong bone between the implant and bone isn't achieved.
Hybrid total hip replacement
Hybrid hip replacements have one component inserted without cement, while the other is inserted with cement.
When only one part of the hip joint is diseased, your doctor may recommend a partial hip replacement. In this procedure, the head of the femur is typically replaced.
Hip resurfacing is a newer technique in which the socket is replaced while the femur is resurfaced with a component that is cemented over the head of the femur, sparing the bone of the femoral head and neck.
Hip resurfacing is most frequently recommended for younger patients. Because the procedure is still relatively new, the long-term success is still being evaluated.
