The first recorded hand-wrist film wasThe first recorded hand-wrist film was
published by Sydney Rowland of London inpublished by Sydney Rowland of London in
April, 1896.April, 1896.
Pryor (1925)
He tabulated the time of appearance of bones
of the hand, time of union of the epiphyses,
and sex differences in skeletal development.

 Hellman, 1928, reported a study of ossification of the
epiphyses.
 60 females between 10 yrs 3 months- 12 yrs 3
months.
 He found that the greatest increment to bones of the
hand preceded the greatest increase in height of the
body by one year.
 Baldwin, 1928, was the first to measure carpal bones
for the determination of degree of development.
