The classic ilioinguinal approach is a gold standard in acetabular surgery. We developed a modification, a minimally invasive method that entails a median lower abdominal approach with extraperitoneal dissection and exposure of the pubic symphysis. The second incision is lateral, next to the iliac crest. This allows an easy, safe and quick exposure of the anterior iliac ring as well as easy access to the posterior column and wall towards the sacroiliac joint. The iliac vessels and nerves are thereby protected, and no preparation of neurovascular structures is required. The technique was applied in 23 clinical cases and compared with the classic ilioinguinal approach in 9 similar cases over the same period.
