Accidental tramline bruising and rib fractures
International Journal of Emergency Medicine volume 3, page63(2010)
A 37-year-old, 85-kg man fell from his bicycle landing on his left chest. Fractures of the fifth and sixth ribs were diagnosed clinically and with ultrasound. Bruising developed after a few days in a tramline, linear pattern with three stripes outlining the affected ribs (Figs. 1 and 2). Tramline bruising is often presumed to be caused by blows with a linear implement and in children would be considered suggestive of maltreatment .
In this case it is hypothesised that the linearity was caused by compression of the skin against the tarmac by the ribs from within, rather than by compression by a rod from without. It is likely that such a mechanism requires a body mass substantially greater than the average child’s, so although this case demonstrates that linear bruising in an adult is not pathognomonic of a blow with a rod-like implement, in children it will raise suspicion of maltreatment.
