Let's start at the beginning!
Fact No. 1 : Nothing is as good as nature's own. Nothing can
ever replicate the perfection of your native, original hip -
before it became diseased. One day, maybe we can grow you a
new one, then this debate will be irrelevant. Everything
else is a compromise. Some compromises are better than
others, and it depends on the individual patient, their
activity or age, as well as the experience of the surgeon
and the quality of components used.
Fact No. 2: However you 'spin' it, Conventional total hip
replacement or THR is effectively an amputation of the head
& neck of the femur. No if's and's or but's. Once it is
gone, that's it, no going back. So, even if hip resurfacing
[I call it BHR as I only use the Birmingham device] has a
SLIGHTLY higher failure rate than THR, it is still worth
thinking about the preservation of your femoral head & neck.
The younger or more active you are, the more important this
thought becomes.
Fact No. 3: The article only looks at revision rates when
comparing BHR to THR. It says nothing about other, more
subtle problems with THR like dislocation. OK, dislocation
maybe rare with THR and almost unknown with BHR, but it is
still a great concern in the early recovery phase. The fear
of dislocation with THR drives the rehabilitation in the
first few weeks and greatly restricts the advice the surgeon
can give patients. Patients have to be given guidance to
avoid dislocation which is often more onerous than is
strictly required so that everyone can 'cover their
backsides' so to speak. With BHR, my team is now [or should
be!] telling MOST patients there are no special or onerous
restrictions. Patients can sleep on their sides. They do not
need raised toilet seats at home. They do not need to worry
about dislocation because it is almost impossible. It allows
the patient to recover full range of motion earlier and more
safely. Unless there are concerns about bone quality,
patients can be told to get back to activities of daily
living as fast as their body allows. The only thing we have
to be a bit cautious about is high impact stuff like running
or jogging, football, rugby, skiing and the like. These can
be allowed after the 3 or 4 month x-ray and if surgeon is
happy that the danger of neck of femur fracture has passed.
The other, very subtle and impossible to quantify downside
of THR is that surgical invasion of the femoral medullary
canal forces marrow contents into the bloodstream. The bone
marrow of the long bones is where your body makes all your
blood cells. Red ones, white ones and platelets. It is why
dogs love the marrow of a bone so much - it is rich in fat
and protein. Forcing this marrow fat, rich in immature blood
cells and other proteins, triggers an inflammatory cascade
in the leg around the whole length of the femur and in the
lungs which filter the globules before they would enter the
circulation to the brain or other major organs. When severe,
this phenomenon is called fat embolism. BHR dramatically
reduces this embolisation phenomenon and is why I feel quite
happy doing bilateral BHR when the patient has bilateral
disease, but I would be very, very careful or wary of
bilateral THR on the same day. In fact I tried bilateral THR
several times before BHR came along and had lots of trouble.
Done over 30 cases of bilateral BHR now and never regretted
it. A truly astonishing operation as patients take only one
or 2 more days to go home as compared with a single side BHR.
i.e the recovery time is not doubled.
Fact No. 4: Some of us have always instinctively realized
this, but BHR is exquisitely sensitive to accurate component
positioning, and the exact metallurgy/manufacture of the
components. THR can be put in quite sloppily and still work.
At least for more than the 3 years the Times article is
looking at. The figures in the UK National Registry are for
all surgeons, using all the currently available hip
resurfacing prostheses in varying mix. One should look ONLY
at high volume, experienced surgeons to get the true
picture. I wish I had the time and energy to look in detail
at my own series, but it is certainly less than 4% failure
at 3 years! The other trouble is that McMinn has already
published large, detailed series so does the world need yet
another one? McMinn's own figures, particularly in the under
55's are so good, many thought he must have fabricated them.
I think less than 1% 'failure' at 5 years, not 3 years. This
is the problem with raw statistics: they are so easily used
like a drunk man uses a lamppost - more for support than
illumination.
So much of the 'failure' we are looking at is due to poor
surgery, poor prostheses or a combination of both. Women are
only more at risk because their hips tend to be smaller,
therefore the precise positioning of components is more
critical. Women also tend to naturally have slightly weaker
or less dense bone than men, so their cups may not integrate
as planned or they may fracture through the neck of the
femur. Apart from that, I personally don't believe there is
any great gender difference.
Fact No. 5 ALVAL or metal ion 'allergy' is very, very rare.
Irritation from excessive metal wear from poorly positioned
or poorly manufactured prostheses accounts for the vast
majority of the so-called ALVAL being reported. It sounds to
me like Andrea had excessive metal wear leading to
predictable irritation, fluid accumulation around the hip,
and pain. Andrea, I do not think you had true ALVAL. Indeed
your surgeons tend to confirm this as they did not find the
masses of inflammatory tissues and destruction that would
have been present if you had true ALVAL. The Melissa test is
useless for predicting who will get ALVAL. The Melissa test
has been used to justify large scale extraction of dental
fillings from people, particularly in Scandinavia, on the
basis that allergy to the metal in the fillings was making
these people ill. Mass hysteria on a quite fascinating
scale, and remember for very tidy profit. ALVAL is not
confined to BHR. It is a problem with any metal-on-metal
bearing couple. If ALVAL is used as a reason to discredit
BHR, then all metal on metal bearings would have to be
suspect. Which would leave only metal or ceramic on
polyethylene, or ceramic on ceramic.
So lets look at metal or ceramic on polyethylene.
Polyethylene is basically like hardened wax. Soft and
slippery. Under pressure and when heated, it deforms or
flows, just like melting wax. You can make the wax a bit
harder, but it is still wax. There are constantly new or
improved polys on the market. We have been here before.
Let's look at Hylamer, a trade name from De Puy:
Hylamer polyethylene was introduced in the 1990s as an
alternative to conventional polyethylene. Its chemical and
physical properties, and especially its high crystallinity,
were claimed to improve resistance to wear. Initially
Hylamer devices were sterilized by gamma radiation in air,
then the technique was changed and gamma radiation was
performed in the absence of oxygen. Clinical experience has
shown the early loosening of some devices made from Hylamer.
The text understates the problem. Hylamer was an unmitigated
disaster and has long ago been withdrawn. So I don't trust
poly in any shape or form FOR YOUNG ACTIVE PATIENTS. I still
use it for the more elderly and sedentary. It still works
perfectly well in this group.
What about ceramic-ceramic? This is the best alternative if
you cannot have metal-metal for any reason. BUT some ceramic
hips squeak. So loudly they can be heard across a room full
of people. Ceramic is brittle and although ceramic fracture
is now rare, it still happens and is under-reported. Ceramic
ages or oxidises in the body and this can then lead to
higher wear rates as the ceramic surfaces lose their shine
or surface finish. Finally ceramic-ceramic is a very 'hard'
bearing couple with no 'give' or shock absorption. BHR will,
in most situations, have a thin film of fluid which can be
displaced to absorb shocks at bearing interface.
So, in summary: Yes, BHR will likely ALWAYS have a very
slightly higher revision rate than THR at 3 or 5 years, when
comparing like for like in terms of young active patients.
But the increased risk should be of the order of 1% or less,
in the hands of an experienced surgeon. Not the 7 to 14
times quoted. It is the 30 or 40 year comparative results
that will tell a different tale!
BHR revision, if ever unfortunately required, will always be
easier than THR revision. Pity the poor patient whose THR
fails early, or even later, particularly if the femoral side
needs to be redone - their surgeon has a much tougher job on
his/her hands. And abandoning BHR in favour of THR would
mean abandoning all the more subtle advantages of an
anatomical-sized component sitting on top of your own
preserved femur.
We need to focus on precise surgery, good patient selection,
the very best metallurgy and manufacture, not scare
ourselves into abandoning the most revolutionary development
in the field of hip arthroplasty in the last 50 years.

Wright Medical Group, Inc. Receives FDA Approval to Market Conserve Plus Total Hip Resurfacing System
ARLINGTON, Tenn.-(BUSINESS WIRE) - Nov. 9, 2009 - Wright
Medical Group, Inc. (NASDAQ: WMGI), a global orthopaedic
medical device company, announced today that the United
States Food and Drug Administration (FDA) has given approval
to the Company to market its original CONSERVE® Plus Total
Hip Resurfacing System. Now available in the United States,
this innovative total surface arthroplasty system provides
surgeons and their patients a bone-conserving alternative to
traditional total hip replacement.
The approval permits Wright to market CONSERVE® Plus in the
original femoral and acetabular component configuration
specified in its PreMarket Approval (PMA) application and
enables the Company to initiate efforts to introduce
additional enhancements to the system which are currently
only available outside of the United States. The Company
intends to incorporate these innovative future product
options into the CONSERVE® Plus System's femoral and acetabular component offerings via the PMA Supplement
pathway.
Hip resurfacing may be ideal for young, active patients in
need of surgical treatment for chronic pain. The CONSERVE®
Plus system is designed to offer pain relief and restoration
of function while retaining as much healthy bone as possible
and preserving future surgery options, including a primary
total hip replacement.
The approval follows a successful clinical trial involving
more than 1,300 patients, including those enrolled under
Continued Access protocols, providing patient data of
CONSERVE® Plus clinical data in postoperative periods of up
to eight years in length. Wright will commence surgeon
training in the first phase of its U.S. introduction. The
training is expected to begin immediately upon approval.
"Hip resurfacing represents a valuable alternative to
younger, more active patients who desire a hip
reconstruction that more anatomically mimics the natural
hip," commented Patrick Fisher, Sr. Director of Marketing
for Wright's hip franchise. "We have learned that this is an
excellent option for patients who meet the criteria for hip
resurfacing, and these individuals tend to be very
enthusiastic and outspoken about their positive results."

Dr. Brooks of Cleveland Clinic Performs 500th Hip Resurfacing
Cleveland Clinic Surgeon performs 500th
hip resurfacing procedure at Euclid Hospital
Oct. 29, 2009
Dr. Peter Brooks, Chief of Surgery at Euclid Hospital, has performed his 500th hip resurfacing procedure, the most such procedures in the state of Ohio. Dr. Brooks was responsible for bringing this type of surgery to the area.
Hip
resurfacing is an alternative to hip
replacement surgery.
Approved by the Food and Drug
Administration in 2006, this
procedure is for young active people
suffering from arthritis or previous
joint injury. Resurfacing is for
people who still have the majority
of their bone intact, but who still
feel the painful effects of
arthritis or injury.
"This technique preserves more of
the patient's bone, allowing them
more range of motion to return to
all activities, including running,
climbing and other competitive
sports," said Dr. Brooks. "Rather
than replacing the entire hip joint,
as in a total hip replacement, hip
resurfacing involves shaving and
capping only a few millimeters of
the joint surface."
The best candidates for his
resurfacing are active people under
60 with strong bone health, good
kidney functions and no allergies to
certain metals used in the implant.
For more information, Dr. Brooks
or his colleagues can be reached at
a recently opened hip clinic. Call

Eight locals sue hip replacement manufacturer over alleged defects
A hip replacement was supposed to cure Mary Shelton's pain. Instead, the
Bakersfield woman replaced one pain with another.
Shelton and seven other local folks are suing the manufacturer and distributor
of a hip replacement system.
Instead of being pain free, those suing felt strong pains in their groin areas
for months, the lawsuits say...
All the suits are targeting the Durom Hip Resurfacing System. It's manufactured
by Zimmer Inc. of Indiana...
The suits allege that the Durom system is defective because bone and tissues
don't grow into them properly. A cup in the system has to be replaced with parts
from another manufacturer, Faulkner said.
Zimmer stands behind their product. It's not defective, said Irvine attorney
Michelle M. Fujimoto.
In paperwork filed with the court, the company says any problems can be blamed
on the doctors who implanted the product, or on unusual conditions in the
patients themselves...
The Durom system was first sold in 2006.
...the company has reported that about 15,000 have been implanted across the nation

US Hip Resurfacing Implants Market: Product Penetration to Drive Growth
2009-08-14
The US hip resurfacing implants market valued at $57.3.million in 2008 is forecast to grow by 36% annually for the next seven years to reach $483 million by 2015
This growth is expected to be driven by an increase in awareness of the procedure, increasing clinical familiarity among surgeons and a favorable reimbursement scenario.
The fact that hip resurfacing offers a more natural feel, higher stability and lesser bone-loss makes it ideal for patients leading an active life.
Increasing awareness of the advantages that this procedure offers, through campaigns by both the manufacturers and social groups will drive the growth of the US hip resurfacing market. There has been a steady increase in the awareness of hip resurfacing, and it’s offering of an active life even after surgery, its shorter recovery period, lower costs of rehabilitation and its minimal bone loss factors. These advantages have positioned hip resurfacing as a primary treatment method for hip ailments.
The increasing incidence of osteoarthritis in the population group of 25-60 years is a major driver for the US hip resurfacing market. The increasing prevalence, now at 6% of the young patient population, is expected to drive growth in the US hip resurfacing market. Osteoarthritis, which first appears between the age of 25 and 40, is a very common disease in individuals aged 70 and above. Before the age 55, it affects men and women equally but after the age 55, the incidence is higher in women. Effectively, the large pool of male population between the ages of 25-40 with advanced or severe arthritis of the hip are expected to drive demand for hip resurfacing impalnts.
Smith & Nephew leads the US hip resurfacing market with its Birmingham Hip Resurfacing (BHR). Released in May 2006, the BHR had the competitive advantage of being the only available product for a full year until the market launch of Corin’s Cormet System in July 2007. Smith & Nephew cashed in on the first mover advantage with innovative marketing, surgeons education and competitive pricing. Renewed efforts towards capturing distribution channels and increased stress on surgeons education has allowed Smith & Nephew to capture 75% market share in the US hip resurfacing market.
Corin’s deal with Stryker for distribution of its Cormet resurfacing system played a major role in the sales of its device in spite of the late entry into the US market. Stryker is known to have one of the strongest sales forces in the US orthopedic devices market. This combined with Stryker’s strong brand identity as compared to the UK headquartered Smith & Nephew has allowed Corin’s product to effectively make inroads into the hip resurfacing market in the US.

GlobalData, the industry analysis specialists’ new report, “US Hip Resurfacing Implants Market: Product Penetration to Drive Growth”, finds that an increasing incidence of osteoarthritis in the population group of 25-60 years will drive the growth of hip resurfacing implants market in the US. The report highlights the trend of traditional Total Hip Replacement (THR) shifting towards Hip Resurfacing as one of the key market drivers for the US hip resurfacing market.

Hip Resurfacing is Viable Alternative to Hip Replacement
Patients who had hip resurfacing surgery, such as the Birmingham Hip Resurfacing technique, reported a better quality of life, less pain and greater satisfaction a year after surgery than those who had a total hip replacement.
PRLog (Press Release) - Jul 31, 2009 - Oceanside, NY – Patients who had hip resurfacing surgery, such as the Birmingham Hip Resurfacing technique, reported a better quality of life, less pain and greater satisfaction a year after surgery than those who had a total hip replacement, according to a study presented at the American Academy of Orthopedic Surgeons (AAOS) 2009 Annual Meeting.
The study was based on data on the outcomes of 214 total hip replacement patients and 132 hip resurfacing patients that was recorded in a joint registry maintained at a single surgeon’s practice from 2003-2006. Orthopedic surgeon Dr. Elizabeth Anne Lingard of Freeman Hospital in Newcastle Upon Tyne, England, was the study’s lead researcher.
Each patient enrolled in the study completed a questionnaire preoperatively and one year after surgery. The questionnaire included the Western Ontario and MacMaster Universities Osteoarthritis Index (referred to as WOMAC, it is a 24-item questionnaire that is completed by the patient and focuses on joint pain, stiffness and loss of function related to osteoarthritis of the knee and hip) and the SF-36, a self-report questionnaire completed by the patient that measures health-related quality of life (and generates 8 subscales: physical functioning, role limitations due to physical problems, bodily pain, general health perceptions, vitality, social functioning, role-limitations due to emotional problems, and mental health; and 2 summary scores: physical component and mental component). The patients also completed a questionnaire regarding satisfaction with their procedures and outcomes one year after surgery.
The study showed that one year after surgery both groups of patients experienced significant improvements in WOMAC and SF-36. Hip-resurfacing patients, however, posted significantly higher WOMAC scores for decreased pain symptoms. When asked about patient satisfaction with the surgery, a greater number of hip-resurfacing patients said they were satisfied with their ability to perform functional activities after surgery.
"The (Birmingham) hip resurfacing technique allows me to preserve more of the patient’s natural bone structures and stability," said Bradley Gerber, MD, Chief of Joint Replacement Surgery at South Nassau Communities Hospital. "I see hip resurfacing as the ideal solution for many of my younger, active patients who suffer from hip pain. As my patients are getting younger and younger, and are staying physically active much later in life, I've needed an alternative to total hip replacement that accommodates their age and lifestyle. Hip resurfacing is that alternative."
Dr. Gerber was among the first surgeons in the U.S. to perform the Birmingham Hip Resurfacing (BHR) technique. Rather than replacing the entire hip joint, as in a total hip replacement, hip resurfacing simply shaves off the damaged cartilage and bone and a metal cap is placed onto the head of the leg bone (femur).
Total hip replacement involves the removal of the entire femoral head and neck, replacing it with a metal ball, while the BHR leaves the head and neck untouched. It is the neck length and angle that determines the natural length of a patient’s leg after surgery. Since it is not removed and replaced with an artificial device during the resurfacing procedure, there is a greater likelihood of maintaining accurate leg length.
In addition, traditional hip replacements use a plastic socket compared to the BHR implant (which is a metal socket). A plastic socket wears down over time, and may need to be replaced surgically. In fact, it is a leading cause of follow-up surgeries.
The BHR is intended for patients suffering from hip pain due to osteoarthritis,
hip dysplasia (a congenital disease that, in its more severe form, can
eventually cause crippling damage and painful arthritis of the joints) or
avascular necrosis (a disease resulting from the temporary or permanent loss of
the blood supply to the bones, often leading to collapse of the joint surface),
and for whom total hip replacement may not be appropriate due to an increased
level of physical activity. For these reasons, Dr. Gerber feels the BHR is ideal
for patients under age 60 who live non-sedentary lifestyles.
While the BHR implant closely matches the size of a patient’s natural femoral
head (hip ball), it is substantially larger than the femoral head of a
traditional total hip replacement implant. This increased size translates to
greater stability in the new joint, and it decreases the risk of dislocation of
the implant after surgery, which is a leading cause of implant failure after
total hip replacement.
In addition to the BHR, orthopedic surgeons at South Nassau’s Long Island Joint
Replacement Institute specialize in custom-fitted total joint replacement as
well as minimally invasive joint replacement surgery, such as the Uni-Knee®
partial knee replacement and Image-Guided Knee Replacement technique. Minimally
invasive joint replacement reduces trauma to surrounding tissue, blood loss
during surgery, post-operative pain, and recovery time, leading to a speedier
rehabilitation and return to daily activities. According to Dr. Gerber, the
average length of stay of patients treated by the institute is less than 3 days,
which is well below the national average.
The Joint Replacement Institute combines image-guided medical technology with
minimally invasive knee replacement instrumentation. Image-guided surgical
technology is used to determine the precise alignment of the replacement parts;
improves the surgeon’s view of and feel for the surgical field and reduces the
size of the incisions to perform a replacement.
Other procedures offered by the Institute’s physicians include reconstruction of
foot and ankle injuries, pediatric orthopedics, hand and upper extremities, and
meniscus cartilage transplantation and Carticel Therapy to correct recurring
knee cartilage injuries.

American Joint Replacement Registry Created
American Academy of Orthopaedic Surgeons (AAOS) Creates Independent Organization
07/23/2009 Rosemont, IL
The American Academy of Orthopaedic Surgeons (AAOS) has incorporated the American Joint Replacement Registry (AJRR), a nonprofit organization dedicated to collecting and reporting on hip and knee joint replacement procedures. AAOS believes this proposed option is a patient safety best practice.
The goal of a national joint registry is to monitor device performance, thereby allowing early recognition of underperforming processes or devices and supporting continued clinical learning.
"In 2009, AAOS has made great strides in bringing the American Joint Replacement Registry to reality. We have now incorporated. And, we currently are in the process of forming project work groups to tackle data, governance and oversight issues." said John Callaghan, MD, first vice president of the AAOS and orthopaedic surgeon at the University of Iowa.
The AAOS has researched and determined the best course of action for starting and administering a national joint registry, one that would include:
- privacy safeguards for patients;
- legal protections for device makers and physicians;
- a plan to begin capturing data as early as 2010; and
- infrastructure to capture at least 90 percent of all procedures.
Proposed by the AAOS and related stakeholders, the AJRR proposal calls for an independent, not-for-profit organization, funded by the proposing stakeholders -- orthopaedic surgeons, payers, government agencies, patient groups, hospitals and device manufacturers. The AJRR is estimated to cost $20 to $25 million to initiate.
"We now have a chance to put best practices, already benefiting patients in other countries, to work here in the U.S. For instance, registries in Sweden, Great Britain, Canada and Australia have seen up to a 10 percent reduction in revision rates. Even with a modest 2 percent decrease in the U.S. revision rate, this proposal would yield a savings of $652 million in one year," said David Lewallen, MD, chair of the AJRR Project Team and orthopaedic surgeon at Mayo Clinic.
Background: When a patient has a hip or knee implanted into his body, the device used was chosen by his orthopaedic surgeon based on the patient’s needs and lifestyle as well as the device’s performance. A device’s longevity is one of the factors that would be monitored by a national joint registry. A joint registry follows the artificial joint device throughout a recipient’s lifetime in a database with information about the patient’s demographics, as well as where and when the surgery took place.
Smith & Nephew 2nd Quarter Profits up 15%
July 2009
LONDON (Dow Jones) Medical technology company Smith & Nephew PLC (SN.LN)
Thursday July 30, 2009 reported a 15% rise in second-quarter profit, but
said key products like its Birmingham hip resurfacing system are being
disproportionately hit by the recession, as younger people are more likely to
put off surgery than retirees.
Smith & Nephew said sales growth for replacement hips and knees is slow, as
patients continue to put off going under the knife while worries about the
economy persist. Growth in global sales of its knee products was 1% on the year,
while the hip sales declined 1%.
The company said products like its Birmingham hip resurfacing system, or BHR,
and its Journey knee implant have "a greater exposure" to the effects of the
recession because the rate of deferrals for operations is highest among young,
privately-insured patients.
Peers like Stryker Corp. (SYK), Johnson & Johnson (JNJ) and Zimmer Holdings Inc.
(ZMH) have reported a similar softness in the multi-billion dollar a-year market
for new joints.
Smith & Nephew said net profit for the three months to June 28 rose to $118
million from $103 million a year earlier, on revenue down 7% at $926 million.
That's just ahead of analysts' average forecast of about $117 million net
profit.
