A: Bilateral fractures should be entered two times, coding right and left sides separately. The clarification can be made in the written description in the registry, indicating ‘right’ or ‘left’. In AIS 98 there is some opportunity to describe where on the bone the fracture occurs, so there may also e some difference in the codes between left and right if different portions of the bones are affected. In AIS 2005 these distinctions are much more specific, so again there may be sligth differences in the codes. Additionally AIS 2005 has introduced Locator codes which can be used to indicate side and aspect of injuries, however the ability to include these in a computerized trauma registry will be a matter for the software vendors to address.
