Lumbar hernias (alternative plural: herniae) are a rare form of posterior abdominal hernia.

Epidemiology

Most common in patients aged between 50 and 70 years with a male predominance .

Clinical presentation

Patients with lumbar hernias can present with a variety of symptoms, including a posterolateral mass, back pain, bowel obstruction (if contents contain bowel), or urinary obstruction (if contents are kidney/ureter).

Pathology

Lumbar hernias occur through defects in the lumbar muscles or the posterior fascia, below the 12 rib and above the iliac crest. Two types are described, according to the anatomical location of the hernial neck:

superior lumbar hernia (Grynfeltt-Lesshaft hernia)
- occurs through the superior lumbar triangle
- more common than inferior lumbar hernias
inferior lumbar hernia (Petit hernia)
- occurs through the inferior lumbar triangle

Etiology

There are three broad etiologies for lumbar hernias:

congenital hernias (20%)
- discovered in infancy and are due to defects in the musculoskeletal system
- may be associated with other malformations
primary acquired lumbar hernias (55%)
- spontaneous, without a causal factor such as surgery, infection, or trauma
- risk factors include age, extremes of body habitus, quick weight loss, chronic disease, muscular atrophy, chronic bronchitis, wound infection, postoperative sepsis, and strenuous physical activity
secondary acquired lumbar hernias (25%)
- may be caused by blunt, penetrating, or crushing trauma; fractures of the iliac crest; surgical lesions; hepatic abscesses; infections in pelvic bones, ribs, or lumbodorsal fascia; or infected retroperitoneal hematomas
