The information provided in this article is meant to inform the patient on Minimally Invasive Surgery for hip replacement. Your orthopedic surgeon should explain to you which hip replacement is best for you and why
term, however, can be misleading. In a broad sense, minimally invasive
surgery for hip replacement refers to a surgical method that uses a
smaller incision. Many surgeons have this goal in mind already, and
incorporate it into the existing techniques for a traditional hip
replacement. An article put out by the University of Missouri-Columbia
School of Medicine reads:
invasive surgery variations of both the posterior approach and the
lateral approach are popular today, and these involve re-training
surgeons to learn how to do the same approach using a smaller skin
opening. Most surgeons refer to an incision that is 4 inches or less in
length as ‘minimally invasive.'"
are new surgical methods, also called minimally invasive, which go
beyond making the smaller incision. These new surgical methods avoid
cutting into the muscle altogether, which distinguishes them from
traditional methods. Fewer surgeons are trained in these methods and
special instruments and implants are required. One example is the MIS-2
incision hip replacement. The same article put out by the University of
Missouri-Columbia School of Medicine describes the difference between a
surgical method that makes a smaller incision and the MIS-2:
is new is the adaptation of this previously described pathway of
reaching the hip joint to a new method of performing hip replacement
surgery using two incisions that are very small. More important than
the incision size or number is the fact that under the skin, the
muscles are spread in their natural planes. The surgeon navigates a
path around the muscles, without cutting into them."
advantage of any minimally invasive surgery is less injury to the body.
With more radical approaches, such as MIS-2 incision, there is reduced
trauma to the deep muscle tissues and underlying structure of the hip.
Because of the reduced trauma, patients feel better and recover faster.
However, always remember that the size of the incision will be dictated
by the size of the implants and the need to be able to manipulate them
inside the joint to get the optimal positioning. Getting accurate
positioning is key to the success of the entire procedure. The
physicians at the University of Missouri-Columbia School of Medicine
"With modern hip replacement
surgeries, the person is encouraged to become mobile much earlier than
with standard methods of hip replacements. Many people are able to get
out of bed either the same day or the next day, with the help of a
physical therapist. In many cases outpatient therapy is not necessary,
although it can help certain patients."
should not give the reader the impression that minimally invasive
surgical techniques are free of risks and complications. Blood-clots,
for example, still occur and surgeons must apply methods to reduce
them. In addition, most surgeons will still restrict the patient for
six weeks after the surgery.
Keep in mind
that all surgery is invasive to the body. These new surgical techniques
merely reduce injury and trauma. If you believe you may be a candidate
for minimally invasive hip replacement surgery, do research, talks with doctors, and always weigh the short-term benefits and the long-term results.
