The exhibit hall at the American Academy of Orthopaedic Surgeons' Annual Meeting in Chicago this March housed displays from hundreds of manufacturers and distributors, each promoting its latest additions to the orthopedic market. Some of the technology I saw while touring the floor with colleagues from the Skokie, Ill.-based healthcare consulting firm Sg2 has an eye on future use. Some, however, is available now for hospitals and surgery centers. Here are some of the new products that made an appearance at the conference.
