Between 1985 and 1992, nine patients who sustained severe pelvic lesio
ns as a result of motorcycle accidents were admitted to and treated in
the authors' department. In six of these nine cases the petrol tank o
f the motorcycle was one of the wounding agents, and all six patients
had the same kind of motorcycle with an oversized petrol tank. All six
patients had unstable pelvic lesions. In addition, four had subperito
neal haematomas which required multiple transfusions; five had perinea
l and/or genital lesions, and one had a ruptured membranous urethra. S
evere pelvic injuries are rare, but can have after-effects which jeopa
rdize the social and family life of the patients. A national epidemiol
ogical study would be useful to evaluate the frequency of such injurie
s and to draw conclusions leading to improved safety for motorcyclists
