A rare case of a superior lumbar hernia secondary to penetrating injury

Abstract

Lumbar hernias are rare occurrences, with only 300 cases reported in the literature. We present a unique case of a superior lumbar hernia secondary to penetrating trauma to the right flank. We performed a herniorrhaphy using porcine mesh, and provided additional support by mobilizing the external oblique and latissimus dorsi into the defect. At follow up three months after repair, the patient was asymptomatic and exam revealed an intact lumbar abdominal wall with normal contour. Although literature displays a consensus on the need for lumbar hernia repair, specific repair techniques must be tailored to defect etiology, size, location, and contents.
