No greater cancer risk for patients with metal-on-metal hip implants, study
says
April 4, 2012
Patients with metal-on-metal implants stand no more chance of developing cancer
7 years after hip replacement than the general population, according to findings
of a study commissioned by the National Joint Registry of England and Wales and
Hospital Episode Statistics..
The researchers collected data on patient age and gender, and assessed general
health at the time of surgery using diagnostic codes recorded at the time of
injury, American Society of Anesthesiologists grade and admissions to the
hospital in the previous 5 years...
...According to the release, the investigators discovered a 60-year-old man in
moderate health with a MoM stemmed hip replacement would have a 6.2% chance of
being diagnosed with cancer 5 years postoperatively compared to a 6.7% chance if
other bearing surfaces were used. Women aged 60 years with MoM stemmed hip
replacements showed a 4% chance of developing cancer during the same time period
compared to a 4.4% chance if they had other bearing surfaces. The investigators
also found that cancer rates were lower than predicted for both hip replacement
patients and the general population.
The study authors hope clinicians can use the information to inform patients
that cancer risks are low for MoM hips...

Nearly 70% of patients with hip replacements reported their prosthetic joints
were a source of inconvenience when going through airport security screens,
according to a study published in the Journal of Bone and Joint Surgery...
.."Of the 143 patients with hip replacements who traveled by air, 120 (84%)
reported triggering the alarm and required wanding with a handheld detector,"
the authors wrote. "Ninety-nine (69%) of the 143 patients reported that the
prosthetic joint caused an inconvenience while traveling."
According to an American Academy of Orthopaedic Surgeons release, patients who
had a single hip implant demonstrated a lower rate of triggering alarms (80%)
compared with those who had two hip implants (95%)...

Bacteria associated with gum disease may relocate to the joints and cause hip or knee prosthesis failure, according to researchers from Case Western Reserve University School of Dental Medicine...
...The researchers suggest the findings may explain why aseptic loosening or prosthetic wear of artificial joints occurs within 10 years when no infection appears to be present. The findings were reported in the Journal of Clinical Rheumatology...
...Bacterial DNA was collected from the synovial fluid of hip and knee joints. The researchers also gathered pooled subgingival samples and examined the patients for periodontal disease. The investigators found bacterial DNA in the synovial fluid of 13.9% of patients - two RA patients (one native knee, one failed prosthesis) and three OA patients (one native knee, two failed prostheses).
"We have a link now and want to see just how much of a trend this is," Bissada stated. "We also will be able to see if treating the periodontal disease can reduce the future of costly joint replacements."

Smoking a risk factor for early failure in primary, revision THA
April 13, 2012
Researchers found smoking to be a significant risk factor for early failure in
complex primary and revision total hip arthroplasties, even with the use of
ultraporous acetabular components.
Adolph V. Lombardi, Jr., MD, presented his team’s findings at the American
Academy of Orthopaedic Surgeons Annual Meeting in San Francisco.
Lombardi and his team looked at 10 years’ worth of hip procedures, identifying
ultraporous acetabular component use in 535 hips in 500 patients...
"This is the nuts and bolts – reasons for failure," he said. "Infection,
aseptic loosening and periacetabular failure — all of which we believe may be
affected by smoking."
... Lombardi noted a failure rate in smokers of 11%, with a failure rate of 3.8%
in non-smokers and 5.3% in previous smokers...

Clinical Outcome of the Metal-on-Metal Hybrid Corin Cormet 2000 Hip Resurfacing System An up to 11-Year Follow-Up Study
Thomas P. Gross, MD, Fei Liu, PhD, and Lee A. Webb, NP
Abstract: This report extends the follow-up for the largest center of the first multicenter US Food and Drug Administration investigational device exemption study on metal-on-metal hip resurfacing arthroplasty up to 11 years. A single surgeon performed 373 hip resurfacing arthroplasties using the hybrid Corin Cormet 2000 system. The Kaplan-Meier survivorship at 11 years was 93% when revision for any reason was used as an end point and 91% if radiographic failures were included. The clinical results demonstrate an acceptable failure rate with use of this system. Loosening of the cemented femoral components was the most common source of failure and occurred at all follow-up intervals. A learning curve that persisted for at least 200 cases was confirmed. All femoral neck fractures occurred before 6 months postoperatively. Keywords: hip resurfacing, hybrid fixation, hip arthroplasty, learning curve, femoral failure.

Biomet Hip Resurfacing System Clinical Trial
April 10, 2012 in Hip Implants
The Biomet Hip Resurfacing System clinical trial has been approved by the FDA to determine if the Biomet total resurfacing system is safe and a viable alternative to total hip replacement surgery. The FDA protocol determines which patients may be eligible to take part in the study. The FDA also requires that doctors participating in this study be approved by the Institutional Review Board (IRB) for the Protection of Human Subjects. Currently, only one doctor located in New Jersey or Pennsylvania has been approved to participate in this study. That doctor is located in Teaneck, New Jersey according to Biomet’s website.

Excessive sporting activity may impair long-term success of hip resurfacing
Patients should limit activities to maintain hip prosthesis
SAN FRANCISCO – In hip resurfacing the femoral ball in the hip joint is not
removed, but instead is trimmed and capped with a smooth metal covering. Young
and active patients with arthritis often choose hip resurfacing over total hip
replacement to minimize the risk of hip dislocation, and to preserve the bone
for a revision surgery should the primary resurfacing fail. However, the
long-term effects of sports on a resurfaced hip were unknown.
In new research presented today at the 2012 Annual Meeting of the American
Academy of Orthopaedic Surgeons (AAOS), investigators surveyed 445 patients
between one and five years after hip resurfacing. The type of activity,
frequency and duration of the sessions, and intensity of participation were
documented. Over the next 10 years, each patient's hip status was monitored. The
mean age of the patients was 48.7 years, and 74 percent were male. There was a
correlation between higher activity scores and risk for surgical revision. Other
independent risk factors for revision included small component size, low body
mass index, and 1st generation surgical technique. Patients with an Impact Score
(IS) lower than 50 had a revision risk rate 3.8 times lower than the patients
with an IS of 50 or greater. Survivorship for patients with a lower IS score at
eight years was 96.4 percent versus 88.8 percent.
Large amounts of high impact sporting activities – such as daily running or
tennis– can be detrimental to the long-term success of hip resurfacing
arthroplasty. Surgeons should advise patients to limit their physical activity
to levels that the device can sustain.

I had my left hip resurfaced on the 29th by dr Romash of chesapeake...Im home already and doing great. The first day post op was pretty rough when they take you out for a walk, but after that it got much better, Im 46 and athletic, and Im hoping for a quick recovery but my doc is very conservative, hipnhop, i read all your posts and that helped, jimclain, thanks for all the info you sent me and jim1947, thanks for the input on dr Romash.
My husband is doing all the hard work! he is my hero, and my mom is coming all the way from Spain n the 10th to help...so Im getting a lot of support and mentally i will be better with people around me.
And special thanks to Patricia for your work in this great website

I would like to relate my most recent experience with Dr. Peter Brooks at the Cleveland Clinic:
Some Background. I am a 65 year old male who has always been in good shape. Years of running and racquetball began to take their toll about 10 years ago but as long as I felt that my activities of daily life were not severely compromised I continued to postpone the inevitable. That ended this fall when I could no longer work out, play golf or bike without serious pain and I began in earnest to find a surgeon to replace my hip. However I still did not like the idea of limited movement, possibility of dislocation and leg length discrepancies that are often a byproduct of traditional HR so when a local Doc mentioned BHR I was led to your site.
I selected Dr. Brooks because of his experience and the fact that Cleveland is a short drive from our home in PA. My first visit for evaluation provided me with a great deal of comfort. I felt that Dr. Brooks employed a conservative approach to surgery and rehab, and more importantly had done over 1200 procedures. That led me to believe that he had the procedure down pat.
I was operated on Wednesday February 22 and came home on Friday. I was most impressed with the fact that I had no black and blue marks or swelling on my operative leg and with the exception of a very nice 8 inch scar the operative leg looked pretty much like my other leg. The PT staff at the hospital was very helpful in advising me on how to rehab so I left with the confidence that I could manage my recovery according to their recommendations.
I am just getting into my rehab and am not sure how good my leg will be eventually but I am very pleased with the results so far and have no regrets about my decision to have a BHR .

I'm 43 & booked in for LBHR on 2nd Nov. Can't wait to get on with it & get back to an active, drug & pain free life. I am anxious, apprehensive & all those expected emotions. Some people look at me surprised when I tell them I'm having a hip replacement... "But you're too young" bla bla. I have 3 young children who I currently feel more like a granddad than a father to. I used to be very active playing squash, tennis, trail biking etc so I feel fortunate there's an option like resurfacing available.
Nov 23, 2011
Day 1
I was first up yesterday morning and the BHR op went well. VERY relieved to be on the other side of that anxiety. So after years of researching & build up I'm an official hippy.
Physio had me walking around the bed twice with crutches about 5 hours post op. She seemed happy with that as she didn't think I'd be able to as I was dizzy& pale initially.
I've also spent time on my unoperated side in my bed. So nil restrictions there. Just pillow been legs.
No usual hip pain! just ranging from 2 - 5 on pain scale of 10 around incision which seems to refer al around upper leg. Ice & drugs goodo relief though.
Eager to get moving with rehab but as my lovely wife said "don't over do it" - she also warned my surgeon what I'm like so better behave!
All in all I couldn't be happier waking this morning on day two.
