Total hip replacement - which hip implant is best for me?
Total hip replacement - which hip implant are best ?
The first hip replacement was performed around 40
years back, which was called Charnley hip apparatus back then after the name of
Sir John Charnley, who performed the first hip replacement. Much advancement in
techniques and type of implants has happened since then. From a smooth, polished stainless steel stem and a plastic
socket, which were cemented or glued into place at that time, there are a variety
of implants available now which are either cemented or not cemented for the
bone to grow around the implant.
Cemented and Un cemented Hip Implant options
Though cemented implants have a long
track record and continue to do very well, most of the hip replacements done in
United States these days are not cemented, but are inserted in the bone so that
the bone grows into the implant anchoring them.
In the last 10 years,
major improvements in the artificial bearing surfaces of implants have been
approved for use in the U.S. The stem portion of most hip implants is made of titanium-
or cobalt/chromium-based alloys. They come in different shapes and some have
porous surfaces to allow for bone in growth.
The ball portion of the implant and the acetabular
socket is made of variety of materials which include:
·metal on metal (MoM)
·metal on plastic (polyethylene or UHMWPE)
·ceramic on plastic (UHMWPE)
·ceramic on ceramic (CoC)
different variety of implants available, it has become a matter of major
discussion and decision between the patient and the surgeon. Not only the
implant options, the technique and technological advances are also a matter of
important decision. Terms such as “
capping the femur” “ minimally invasive hip replacement surgery” are frequently
used terms besides “Metal on metal”, “porcelain hip” which are a major point of
discussion and decision.
patient is often left wondering “Which is the best hip implant for me?” “Should
I or should the surgeon decide about the type of implant and technique to be
used on me?” “Is the latest and technique and implant best for me?”
The fact is that no one knows what the
"best" implant is. Experts say that the ideal hip replacement implant
is the one that allows for normal activities, normal motion, and last the
It is also
important to note that not everyone is a good candidate for all techniques and
implants. The decision about which type of hip replacement to be done over
another should be based on knowledge about its durability, use and drawbacks. Majority of new implants or surgical
techniques have shown to have patient specific or implant specific drawback.
example, minimally invasive hip replacement with smaller incision is many a times
detrimental in adequately placing implants. Ceramic-on-ceramic total hip
replacement has shown squeaking in 1 to 2 percent of patients. Total hip
resurfacing, or capping the femur, may work well for some people, but not in
others and in certain groups may increase the risk of femur neck fracture.
Currently, it can only be done with metal-on-metal bearing surfaces and not
everyone is a good candidate for these bearing surfaces. That's because
metal-on-metal hip replacement has the potential downsides of allergy and
hypersensitivity reactions — which may occur in one out of 1,000 patients.
There are also fears of elevated metal ion levels in the bloodstream that could
potentially cause detrimental long-term health problems, but this potential
problem is purely theoretical and has not been proved in humans despite decades
way to choose the right implant for you is to discuss this with your surgeon. The
surgeon would consider your age, gender, weight, lifestyle and severity of
joint degeneration. The doctor will also look at necessary and possible
range-of-motion with the implant, stability of the implant and wear-resistance
of the materials in light of your physical and lifestyle activity
or right implant for you is the one which fits the following criteria:
·The implant has minimum track record of 10 years
·The surgeon has used the implant before
·The implant is fit to be used for your specific condition
Total hip replacement has proved to be a boon for the patients for many years now.
Implants and technology shall continue to evolve, but the best implant for you
can be chosen after understanding the risks and benefits of it.
