Sesamoid bones (Arabian word meaning seed like small bone arising in tendons at the point of maximum friction) were studied in the present study conducted on 592 subject of Ahmedabad. The commonest site at which sesamoid bone observed in hand was the ulnar side of head of first metacarpal bone (in 1001 boys and girls). The other sites in descending order of frequency were the radial side of head of 1st metacarpal bone (in 36% cases), head of 5th metacarpal bone (in 30% cases), head of 2nd metacarpal bone (in 14% cases) ulnar side of head of 1st phalanx of thumb (in 12.46% cases), The unusual sites were the head of 3rd and 4th metacarpal bones (in 3 girls only). The only sesamoid bone which followed definite age pattern was the one on the ulnar side of head of 1st metacarpal bone. The appearance of sesamoid bones was earlier in girls than boys by 3 to 4 years
