External iliac artery and lumbosacral plexus injury secondary to an open book fracture of the pelvis: report of a case.

Lumbosacral plexus or external iliac artery injuries associated with pelvic fracture are reported rarely in the literature. A case involving a noncompound open book pelvic injury with diastasis of the symphysis pubis and combined ipsilateral lumbosacral plexus and external iliac artery injury is reported. Repeated clinical examination to diagnose vascular lesions with evolving pulse deficits is emphasized.
