NOHC’s Orthopedic Surgeons: Up to Date with Prosthesis Options
April 7, 2008 – 2:15 pm
It is important for the orthopedic surgeon who will inplant your hip or knee to have up-to-date knowledge of the particular prosthesis chosen for your surgery. Total hip resurfacings with metal-metal bearings currently is the fastest growing orthopedic procedure world wide and with good reason. Just ask A.B., a former professional baseball player, or J.M., the one time Chicago Bears quarterback; both who underwent hip resurfacing at the Neurologic & Orthopedic Hospital of Chicago in 2007.
Metal-on-metal designs have a long history in orthopedics. But it is important to remember that today’s metal-on-metal technology has little in common with that which it did even 20 years ago. As we compare the science of metal-on-metal articulations, I recognize the great opportunity that this relatively new technology presents for reducing wear. As with any important advancement in implant material and design, we at the Neurologic & Orthopedic Hospital of Chicago believe it inherent in our mission to bring this contemporary technology to those seeking hip replacement. Within the general orthopedic community, there is misinformation and misconception. There are still skeptics because of issues centered on material and design aspects of the early implants.
First generation implants were made from cast cobalt-chromium alloy, which was more susceptible to wear. The current implants offered at NOHC are made from high-carbon cobalt-chromium alloys that have been shown to be much more resistant to wear. Furthermore, a better understanding and appreciation of fluid film lubrication has led to new implant design and manufacturing techniques. Consider NOHC for your joint replacement and take full advantage of what we have to offer. Through hip resurfacing, enjoy the absence of pain, the restoration of “normal” motion, the avoidance of previous inherent post joint replacement restrictions, elimination of instability and return to unlimited life style.
The Neurologic & Orthopedic Hospital Blog was created to provide insightful brain, back, and joint information to people that struggle to find the right path in the maze of healthcare-related decisions they face today. The power of the internet is transforming health information and empowering people to take a front seat in managing their own health; correspondingly it has inspired Doctors Leonard Cerullo and Mitchell Sheinkop to share NOHC's cutting-edge resources with the online community.
