Complicated Hip Surgery Benefits From 3-D Models

Summary:
A new study at Washington University School of Medicine in St. Louis suggests that 3-D models of the pelvis work better than X-ray images in preparing surgeons to revise hip replacements.

St. Louis, April. 30, 1998 -- About 200,000 Americans undergo hip replacement surgery each year according to the American Academy of Orthopaedic Surgeons. And studies suggest one in five patients will need to have their artificial hip joints replaced within 15 years due to complications. A new study at Washington University School of Medicine in St. Louis suggests that 3-D models of the pelvis work better than X-ray images in preparing surgeons to revise hip replacements. Douglas D. Robertson, M.D., Ph.D., lead investigator of the study and an assistant professor of radiology and orthopaedic surgery, says that surgeons benefit from using 3-D models because they think in three dimensions. "There's something about holding a 3-D model in your hand," Robertson says. "There's a whole depth of information that's lacking when you look at flat X-ray images."
