This report describes a complex syndrome of injuries occurring in a young f
emale who was a back seat passenger wearing a lap-belt restraint in a high-
speed road traffic accident. As a consequence of the forced flexion distrac
tion injury of her lumbar spine, she sustained a fracture-subluxation of th
e first lumbar vertebra in association with a jejunal perforation and exten
sive small intestinal mesenteric laceration. She also had a large traumatic
hernia of the anterior abdominal wall, which was overlooked at primary lap
arotomy. This report highlights collectively the classical combination of i
njuries associated with the lap-belt syndrome and demonstrates the importan
ce of carefully inspecting the anterior abdominal wall for deficiencies, be
cause traumatic herniation may be easily overlooked.
