Lumbar hernias (and namely transiliac hernias) are not frequent. We report the case of a 76-year-old man presenting with an incarcerated transiliac hernia, in a context of exacerbated chronic obstructive pulmonary disease, 30 years after iliac bone harvesting for femur surgery. After imaging, the patient underwent a laparotomy, and a herniated left colic segment was identified through a hole in the left iliac crest. The left colon was reduced and the defect was closed by an omental patch. The patient recovered well and was discharged. Graft-site hernia is a rare complication of harvesting bone grafts from the iliac crest. Repeated increases in abdominal pressure can result in herniation of abdominal contents through the osseous defect. Computed tomography is commonly used to confirm the diagnosis.
