Repair of lumbar hernia originating from autogenous iliac bone graft with bilayer mesh

Management of post-iliac crest bone harvesting hernias: Insights from a case series and systematic review

INTRODUCTION

Hernias following iliac bone grafting are a rare but significant complication, with the earliest case reported in 1945. Repairing these hernias is challenging. Appropriate repair techniques are needed to minimise morbidity and recurrence. We present our experience with three cases of post-iliac graft hernia repair with mesh anchored to titanium mini-plates and a systematic review of current literature.

METHOD

We conducted a systematic review of the literature in February 2024 on two online databases, PubMed®/MEDLINE and EMBASE, in accordance with PRISMA guidelines. Keywords used were "Hernia," "Iliac," and "Graft." Data on demographics, initial pathology, time to presentation, type of hernia repair, and outcome were collected. Studies not in English and related to other types of hernia were excluded.

RESULTS

We included 30 studies out of 751 results, spanning from 1975 to 2023. There were 40 reported cases of hernias post iliac bone grafting. The age distribution ranged from 37 to 88 years, with a median age of 60. The majority of patients (40 %) presented within one year. Fracture management, accounting for 19 cases (47.5 %), was the main indication for bone grafting. Mesh repair was performed in 31 cases (77.5 %). Seven cases (17.5 %) of recurrence were reported.

CONCLUSION

Recurrence is a common complication in patients with post-iliac graft hernias. Open mesh repair is the most frequently performed surgery and involves various techniques. While titanium mini-plates as anchors enable a pre-peritoneal plane mesh repair, long-term follow-up and comparative studies are needed to evaluate its efficacy compared to simple mesh.

Iliolumbar incisional hernia following iliac bone harvesting: a rare complication

Incisional hernia is a common post-surgical complication, but hernias through iliac bone defects after the harvesting of an iliac bone graft is rare. The common presentation includes swelling and discomfort, and sometimes features of intestinal obstruction. A computerized tomography (CT) scan is commonly used for the diagnosis and to define the anatomical defect in the bone. Surgery is recommended because of high risk of strangulation. While various methods of repairing this type of hernia have been described, we chose to perform mesh repair for an iliolumbar incisional hernia.
