hip replacement

It has been an open secret that salespeople are present for surgeries at many hospitals, especially for hip and knee implants. But does the reps' expertise outweigh concerns about ethics and costs?

Hip replacements in hundreds of thousands of people began to fail after what seemed like successful surgery. In some cases, people's bones became so weak, just walking could make them snap. Why?

Much of the information doctors hand patients before surgery is too complex and hard to understand. So British researchers asked 9-year-olds to rewrite a brochure about a hip replacement.
