[Clinical morphology of the sternum].

The length, width and thickness of the sternum were measured in 74 adult specimens with the aim of optimizing the dimensions of staples used after sternotomy. This article describes the experimental procedure and presents the results. Sex differences were confined mainly to the length, with males measuring 16.5 cm, and females 15 cm. Width and thickness maxima (7.4 cm and 1.7 cm, respectively) are measured at the proximal and distal ends of the manubrium, while the width and thickness of the corpus (2.7-3.5 cm and 1.0-1.4 cm, respectively) show relatively minor differences.
