Surgical Approach for Periacetabular Osteotomy

Reference work entry


The surgical technique for the Bernese periacetabular osteotomy was developed by Prof. Reinhold Ganz in 1984 for the treatment of hip dysplasia (Ganz R, Klaue K, Vinh TS, Mast JW. Clin Orthop Rel Res 232:26–36, 1988). The purpose of the surgical approach is to expose the innominate bone in order to enable an osteotomy which allows for a complete detachment of the acetabulum while leaving the posterior 50 % of the posterior column intact. The dissection resembles the well-known Smith-Petersen approach with a few modifications. Anatomical structures at risk during surgical exposure and osteotomy include the lateral femoral cutaneous nerve, the femoral nerve, the sciatic nerve, the obturator artery and nerve, and the medial femoral circumflex artery. This chapter describes in detail the surgical setup, the planes of dissection, the location of the neurovascular structure at risk, and how to avoid complications.
