Anna Waller, a member of the Department of Emergency Medicine at the University of North Carolina, co-authored a four-year-long study of jockey injuries and stated to the New York Times that " For every 1, 000 jockeys you have riding one year, over 600 will have medically treated injuries.
" She added that almost 20 % of these were serious head or neck injuries.
The study reported 6, 545 injuries during the years 1993 – 1996.
More than 100 jockeys were killed in the US between 1950 and 1987.
