The Management of Traumatic Abdominal Wall Flank Hernia Along the Spigelian Aponeurosis Using Component Separation, Synthetic, and Biological Mesh.

Blunt abdominal trauma is associated with a variety of medical complications. Traumatic abdominal wall hernias (TAWHs) are a rare sequela of blunt trauma. Of the various forms of TAWH, a rare subtype described as a "spontaneous lateral ventral hernia" or flank hernia occurs in less than 1% of all blunt abdominal traumas. We present a case of a 39-year-old male with a past medical history of epilepsy who was involved in a rollover motor vehicle collision. It was reported that the patient had a seizure while driving. On physical exam, the patient had a large left lower flank contusion. Computed tomography revealed a complex TAWH with complete avulsion of the abdominal wall musculature from the iliac crest and near to total disruption of the internal oblique. To address this, we used a biological mesh inlay, reinforced with a synthetic Ventralight™ mesh secured to the iliac crest. In this article, we describe the patient's experience and management of a complex TAWH.
