Vascular and Visceral Injuries Associated with Lumbar Disc Surgery: Medicolegal Implications

Symptomatic perforation of the anterior annulus fibrosus/anterior longitudinal ligament during surgery for herniated lumbar disc disease is one of the more solemn and sobering complications experienced by neurosurgeons or orthopedic surgeons. This complication frequently results in the death of the patient. Its occurrence is probably more common than the medical community would expect. The authors report 21 cases since 1985 in which an injury to an intra-abdominal vessel or viscera occurred. In all cases litigation resulted and a settlement or verdict was rendered. A review of the literature is presented and the medicolegal implications of symptomatic ventral perforations of the annulus fibrosus/anterior longitudinal ligament are discussed.
