Objectives: To investigate the frequency and causes of bicycle related
abdominal injuries in children and to examine the pattern of presenta
tion. Design: The study was a prospective study of bicycle related inj
ury in children less than 15 years of age presenting to two paediatric
hospitals (15 April-30 June 1992) and three general hospitals (1 Augu
st 1991-30 June 1992). Results: In a series of 813 children, 41 sustai
ned non-penetrating abdominal trauma due to a bicycle incident. In 21
cases, handlebar trauma was responsible. Ten of these children suffere
d life-threatening intra-abdominal injury. Handlebars with no plastic
or foam covering of the metal ends were involved in all ten cases. In
several of these cases, presentation to hospital was delayed and in ot
hers confirmation of the extent of injury took up to 48 hours. The len
gth of hospital stay for those with significant intra-abdominal organ
damage ranged from two to 156 days. Conclusions: Intra-abdominal traum
a must be considered when dealing with children who are victims of bic
ycle trauma. Impact with handlebars may have occurred and some form of
padded protection of handlebar ends is recommended unless their desig
n can be suitably modified.
