Abstract:
The connections of the ventral extremities of the seventh to the tenth ribs in the Chinese were studied on 100 adult (68 male, 32 female) and 100 children (38 male, 62 female) cadavers. The results were as follows: 1. Of the 200 cases observed, the tenth ribs were free at their ventral ends bilaterally in 159 cases (79.5%), and unilaterally (6 right, 11 left) in 17 cases (8.5%). In the remaining 24 cases (12%), the tenth rib was connected to the cartilage of the ninth rib as usually described. In the 159 specimens, the ninth ribs were also free symmetrically in 12 cases (6%) and asymmetrically (7 right and 1 left) in 8 cases (4%). In the latter cases there were 4 pairs of floating ribs on one side and 3 pairs on the other. 2. In 22 (11%) of the 200 cases the eighth ribs were connected at their ventral extremities (7 bilaterally, 15 unilaterally), through the mediation of the costal cartilage, with the sternum to form a true rib. 3. Out of the 200 cadavers, there were 3 cases (1.5%) in which both of the ventral ends of the seventh ribs were not connected with the sternum, but with the cartilage of the sixth rib to form a false rib.
