3-4. POSTEROANTERIOR RIBS ABOVE DIAPHRAGM
A rib routine consists of a PA or AP rib (above or below the diaphragm), an
oblique at the site of injury (anterior or posterior), and a PA chest. While the PA chest is
part of the rib routine, it will not be covered, as it was presented earlier. (See paragraph
3-1.)
