Abdominal Traumatic Handlebar Hernia

ABSTRACT

Traumatic abdominal wall hernia (TAWH) is an unusual type of hernia that may follow direct blunt trauma to the abdomen. Moreover, TAWH that is caused by bicycle handlebars is a rare finding. Despite an overall increase in the incidence of blunt abdominal trauma, the cases of TAWH remain rare, probably due to the elasticity of the abdominal wall for resisting the shear forces generated by a traumatic impact. Although the first case was described by Selby in 1906, very few cases of TAWH have been reported in the literature. Also, "Handlebar hernia" was described by Dimyan et al. in 1980. These injuries are localized hernias resulting from local blunt trauma to the abdominal wall from an object with insufficient force to penetrate the skin, yet this trauman is able to disrupt the deeper tissues of the muscle and fascia. The significance of such hernias is underestimated, and although they can be not immediately life-threatening, they can be fatal if associated with such complications as incarceration and strangulation. We describe here a case of traumatic handlebar hernia in a 55-year old man who presented with left lower quadrant pain that was caused by a motorcycle accident.
