PELVIC OSTEOTOMIES - ANATOMIC PITFALLS AT THE PUBIC BONE - A CADAVER STUDY

Pelvic osteotomies for acetabular dysplasia include an osteotomy of th e pubic bone, The anatomical consequences of two different approaches to the pubic bone were assessed by performing a triple osteotomy on a series of 12 fresh cadaver hemipelvises. The medial approach through s t separate incision over the pubic symphysis was compared with the lat eral approach through the incision used for the innominate osteotomy. Although the medial approach appears technically easy, there are sever al anatomical structures at risk, such as the femoral vein and the cor una mortis. The lateral approach is safer, and it is easier to make th e osteotomy close to the hip joint. The closer the osteotomy is to the hip joint, the smaller the chance of developing a non-union.
