Lumbar hernia in an iliac bone graft defect. A case report

Area of Science:

• Anatomy
• Surgical Complications
• Orthopedic Surgery

Background:

• The inferior lumbar triangle of Petit is a known anatomical space where hernias can occur.
• Iliac crest bone grafting is a common orthopedic procedure, often involving the bone forming the base of this triangle.
• Understanding the anatomical relationship between bone graft sites and potential hernia locations is crucial.

Observation:

• A patient developed a hernia in the inferior lumbar triangle of Petit.
• The hernia appeared 1.5 years after a full thickness bone graft was harvested from the iliac crest.
• The graft site directly bordered the anatomical base of the inferior lumbar triangle.

Findings:

• This case suggests a potential association between iliac crest bone harvesting and the subsequent development of lumbar hernias.
• The anatomical proximity of the graft site to the inferior lumbar triangle may predispose to hernia formation.
• Delayed presentation of the hernia indicates a chronic or progressive weakening of the abdominal wall.

Implications:

• Surgeons should consider the risk of lumbar hernia formation when harvesting bone grafts from the iliac crest.
• Further research is warranted to elucidate the exact mechanism and incidence of this complication.
• Awareness of this potential complication may lead to improved patient counseling and surgical technique modifications.
