HIP REPLACEMENT

HIP REPLACEMENT

What causes severe hip pain?

Pain is one of the main reasons people consider total hip replacement
surgery. There are several conditions that can bring about severe hip
pain, such as osteoarthritis, rheumatoid arthritis, avascular necrosis,
developmental dysplasia of the hip or even a simple hip fracture. One
of the leading causes of debilitating hip pain is arthritis. Osteoarthritis,
the most common form of arthritis, occurs when the normally smooth
surfaces of your joint—in this case, the ball-and-socket joint of the
hip—wear away, resulting in stiff and painful bone-on-bone contact.
Pain from osteoarthritis, or any of these conditions, can limit your range
of motion and prevent you from performing your normal day-to-day
activities or even getting a good night’s rest.

WHAT ARE MY

TREATMENT OPTIONS?

Your doctor will consider many factors in determining an
appropriate treatment method to relieve your hip pain.
Treatment may begin with conservative methods such as
rest, physical therapy, medication or analgesics. If these
methods fail to provide long-term relief, then it may be time to
consider a surgical treatment such as total hip replacement.
Joint replacement surgery is a major operation. As with any major
operation, there are possible complications. Some of these are related
to the anesthesia, while others are associated with the procedure itself.
There are many things that your surgeon will do to minimize the potential
for complications. Your surgeon may also have you see your family
physician before surgery to obtain tests. Your surgeon will discuss all
complications and risks with you prior to surgery.

What are the components of a total hip replacement?

Total hip replacement involves removing the diseased bone and
cartilage and replacing it with orthopaedic implants. The surgical
procedure involves an incision through the skin and access to the hip
joint through the muscles overlying the hip, performed while the patient
is under anesthesia. After the surgeon exposes the hip, the diseased
hip ball (femoral head) is removed. It is replaced with an artificial ball
on a stem, which is inserted into the hollow part of the thighbone, and
may be pressed into place or cemented using a special acrylic cement.
The hip socket (acetabulum) is prepared by machining or “reaming” it
using special instruments to make it the right size and shape. A titanium
shell is then pressed into place and sometimes further secured with
bone screws. A cup-shaped liner is then placed in this shell, forming the
socket part of the ball-and-socket replacement. The ball and socket are
then placed together to complete the implant procedure and the soft
tissues are repaired to complete the surgery. Each implant is available
in a variety of sizes to accommodate different body sizes and shapes.

 

 

WHAT IS THE

ANTERIOR SURGICAL

APPROACH?

Hip replacement can be performed through a variety of surgical
approaches. Anterolateral (from the side of the hip) and
posterolateral (from the back of the hip) have been traditionally
used in the U.S. The Direct Anterior Approach is different
because it allows the surgeon to access the diseased hip joint
through the front of the hip. A major advantage of this approach
is that it allows your surgeon to work through natural intervals
between the muscles around your hip, without having to cut
through the muscles or detach them from the pelvis or thighbone.
Another advantage is that the patient can avoid the pain of
sitting on the incision site since the Direct Anterior Approach is
performed through the front of the hip.
This preservation of your soft tissues may result in a faster
return to weight-bearing activities, less pain and a quicker
overall recovery time. Keeping these muscles intact may also
help reduce the likelihood of dislocation, which may occur when
muscles weakened in surgery are not strong enough initially to
keep the new femoral head in the socket. In addition, the Direct
Anterior Approach takes advantage of the shortest distance to
your hip joint, which may allow for a smaller incision.

Why aren’t all hip replacements performed through the Direct Anterior Approach?

Direct Anterior Approach hip surgery requires implants and
surgical instruments that are compatible with the approach.
Specialized surgical tables may facilitate the Direct Anterior
Approach by allowing precise positioning of the patient during
surgery. Your doctor will consider a wide variety of factors in
determining the best course of treatment. Please talk to your
doctor and ask whether hip replacement through the Direct
Anterior Approach is right for you.

HOW LONG WILL MY

TOTAL HIP

REPLACEMENT LAST?

There are numerous factors that affect the longevity of a
total hip replacement including patient indications (age,
weight and activity level), implant design and materials
used during surgery.
Just like your natural hip, the components of a hip implant
are subject to wear from friction caused by bending,
straightening and supporting your body weight. In the
design of hip implant components—particularly the
bearing surfaces that slide against one another—it is very
important to ensure the least amount of friction possible.

WHAT CAN I

EXPECT AFTER SURGERY?

After surgery you will receive pain medication and begin
physical therapy. You may be out of bed and walking on crutches
or a walker within 24 hours of your surgery. You will be shown
how to perform activities of daily living such as how to safely
climb and descend stairs and how to care for your hip once you
return home. It is a good idea to enlist the support of family
or friends to help you once you return home. Exercise will be
a necessary part of proper healing. Therapy will begin in the
hospital and continue after discharge on your own or with a
therapist. Therapy, a healthy diet and willingness to follow all
of your surgeon’s recommendations will contribute to a more
successful recovery.

When can I return to my regular activities?

After successful surgery, you will be eager to return to many of
the activities you enjoy. Your recovery is partially based upon
your condition prior to your surgery. Going for walks, golfing,
boating, biking and playing with children or grandchildren are
usually realistic expectations, and many patients who have a
hip replaced through the Direct Anterior Approach are able to
return to normal activities more quickly (within a few weeks
rather than a few months). Many patients report little or no pain
in a month or two after surgery, but the decision about activity
level is ultimately based on the suggestions and guidelines of
your orthopaedic surgeon as well as your compliance with your
surgeon’s recommended post-operative therapy
