Hard Hips: The challenge of machining hip replacement implants out of cobalt chrome

摘要

Hip replacement surgery is currently the most common and most successful orthopedic operation in the United States. In 2013, more than 332,000 people traded in their painful hips for ceramic or metallic joints. And that number is rising steadily due to the needs of our aging population, innovative surgical techniques and recent material advancements. With more than 43 million people suffering from some form of osteoarthritis, the Academy of Orthopedic Surgeons predicts that the demand for total hip replacements will increase by 174% by the year 2030. This ever-growing need for prosthetic implants will require constant innovation and the highest machining efficiencies.
