Figure 2b. Sternal segment dislocation; 14-week-old affected mouse. Dislocation of the joint between the fourth and fifth intersternebral joint is evident (arrow head). The dislocated ends of the fourth and fifth sternebrae are displaced into the thoracic cavity while the xiphisternum (XS) protrudes ventrally. Histopathology of the sternum from the same mouse at 16 weeks of age is included in Figure 3b.
