WelcomeSticky PostingsWelcome to Hip Resurfacing News Hip Resurfacing came of age in the United States when the FDA approved Birmingham Hip Resurfacing (BHR) in May 2006. Previous to the FDA Approval, hip resurfacings were done in Europe, Canada, Australia and other countries outside the United States. Orthopedic surgeons have been performing hip resurfacing surgeries since 1997 in most countries. Over 90,000 people world wide have received hip resurfacings. Since the FDA Approval of the BHR and Cormet in the US, there are a large number of new surgeons learning the techniques and many people wondering if the surgery is right for them. There are new surgeons training, new medical studies completed regularly and general articles published in newspapers, magazines and in the media daily. Keeping up with all of the information becomes a real task for most people. People are trying to find pertinent information without spending hours and hours searching online - that is the purpose of Hip Resurfacing News.

Nanotechnology may allow hip implants to sense growth of
new bone
Link http://www.foresight.org/nanodot/?p=2788
Growing multiwalled carbon nanotubes on a titanium
surface enhances the electrochemical behavior of the
surface in a way that might lead to better implants
for hip replacements. The nanotech-prepared titanium
surface serves as a sensor to detect bone formation.
As reported by James Tyrrell at nanotechweb.org
(requires free registration) "Nanotubes
on the look out for new bone". Multiwalled carbon nanotubes (MWCNTs) grown
in pores on a titanium (Ti) surface are ideal
for detecting bone growth, according to Thomas
Webster and his team at Brown University, US [Nanotechnology
abstract]. By adding the biosensing
structure to the surface of orthopedic implants,
the inventors hope to monitor the success of
procedures such as hip replacements in situ. Poor adhesion to the surrounding bone is the most common cause of hip replacement failure. Currently, the diagnosis of new bone growth can be problematic as today’s imaging techniques each have their own limitations and difficulties — something that Webster and his colleagues hope to overcome. "The idea is that our sensor will communicate the status of the surrounding tissue via radio frequencies to a handheld device," Webster told nanotechweb.org. "In fact, we’ve taken things a step further and coated our sensor with a drug-containing polymer layer that can be degraded to release bone building agents on demand." …Next, the team plans to begin animal studies. "It’s a big and important jump to determine if the sensors will work in an animal," said Webster. "We’ll be using rats and analyzing whether new bone growth can be measured and then controlled."

Distribution of Chromium and Cobalt Ions in Various Blood Fractions After
Resurfacing Hip Arthroplasty

aPeninsula Orthopaedics Research
Institute, DEE WHY NSW 2099, Australia Abstract The most appropriate blood fraction for the measurement of metal ions in patients with metal-on-metal implants is controversial. We compared chromium (Cr) and cobalt (Co) ion levels in 29 patients after unilateral hip resurfacing with a size 54-mm femoral Birmingham Hip Resurfacing Prosthesis (Smith and Nephew, London, UK). All had well-functioning arthroplasties between 5 and 59 months after implantation. Ion levels were measured in serum, plasma, red cells, and whole blood in each patient. Our results indicate that only very minor amounts of Cr and Co are associated with red blood cells, with most being associated with serum/plasma. Previous studies using corrosion to produce the ion load have showed a predominance of Cr in the red blood cells. They have also shown that the cellular uptake of Cr is an indicator of its valence. This difference in distribution with our results is indirect evidence that the Cr released from wear of this implant is probably in the more benign trivalent form. It also suggests that most of the metal loss from a normally wearing bearing may be from wear rather than corrosion. If blood is to be used to assess rates of wear and systemic ion levels, then serum gives a better reflection of the true levels than red blood cells.

New Hip Surgery Designed For Younger Patients - Dr. KellyMonday, August 18. 2008
Link
http://cbs4denver.com/local/Colorado.News.Denver.2.556499.html
By Kathy Walsh Feb 15, 2007 DENVER (CBS4) ― Doctors at Presbyterian Saint Luke's Hospital have started offering a new type of hip surgery aimed to help baby boomers who are having pain in their hips earlier than normal. The Birmingham Hip Resurfacing System was approved by the Food and Drug Administration last May. The new surgery is an alternative to total hip replacement and aimed at people under the age of 60. "It is something that patients have actually been waiting to have done," said Dr. Cindy Kelly at Presbyterian Saint Luke's. One operation CBS4 witnessed took 2 hours as Kelly prepares the hip socket, then hammered a new metal one into place. Kelly shaved the damaged bone on the hip ball, preserving it rather than removing it. She then glued and pounded in a new metal cover. "Patients have full motion, really without the risk of dislocation," said Kelly. The new procedure allows for more activity. Patients could be up and moving in 6 weeks, but need to wait a year before running. One benefit is that if a patient needs another hip replacement, the thigh bone is largely intact. The new resurfacing procedure may not be for everyone. Patients should always consult their own doctor. First Zimmer Durom Hip Replacement Lawsuit FiledTuesday, August 12. 2008Link -

Court against Zimmer, Inc. on behalf of a client with a failed Durom Hip
Replacement Cup. It is believed that this is the first lawsuit to be filed
against Zimmer regarding its controversial Durom Hip Replacement System. The
Firm plans to file additional Durom lawsuits against Zimmer on behalf of other
clients in the coming weeks.

else to dictate your future? You have many options -- if you're willing to take
a vacation. If recovering from a medical procedure while lying on a palm-swept
beach, relaxing by the hotel pool, or shopping for terrific bargains sounds
good, then medical vacations may be exactly the right solution for you.
