Objectives: To study metamorphological changes at sternal end of fourth ribs according to age in males. To find any bilateral
variation in morphological changes for different ages.
Research methodology: The samples consist of sternal ends of fourth ribs on both sides taken from the cadavers brought for
postmortem examination. Total 140 rib ends were taken from 70 male bodies having more than 17 years of age. After removing
soft tissues, Ribs were classified according to different phases and mean age for each phase had been derived.
Observations and conclusions: the morphological changes were age dependent without any significant bilateral variation.
Observations were compared with the previous study.
