Metal on Metal

By: Brett Greenky  Blog: Care That Moves You

Fifteen years ago lab studies revealed that metal-on-metal hip replacements had lower overall wear compared to metal-on-plastic hips. Engineers measured the volume of wear particles produced over simulated 10, 20 and 30-year spans of hip wear in the laboratory. The smallest volume of wear was produced by ceramic balls rubbing against ceramic sockets. Only slightly more wear was produced by metal balls rubbing against metal sockets. The traditional coupling of metal balls against plastic sockets produced far more wear than the other two. As a result, engineers believed that ceramic-on-ceramic and metal-on-metal wear surfaces in hip replacement would exhibit superior long-term performance in patients. That’s not the way things turned out.

Operation Walk Syracuse: Preparing For Panama

By: Brett Greenky  Blog: Care That Moves You

Operation Walk Syracuse is a group of orthopedic specialists (surgeons, medical doctors, nurses, anesthesiologists, and physical therapists) who travel to countries that lack ample access to desperately needed hip and knee replacement surgeries. The surgeries are performed at no cost and patients receive the same state of the art services that our patients receive here at home. This post highlights the “pre-trip” the group made to Panama recently, preparing for their longer trip in November 2012. Last year the group traveled to Nepal, performing more than 75 hip and knee replacements.
