Angulated Innominate Osteotomy (AIO): A Salter Osteotomy Without a Bone Graft Surgical/Technical Tips

Abstract

We first proposed the angulated innominate osteotomy (AIO) as an innominate osteotomy using no bone graft in 2014. Since then, more than 50 hips in developmental dysplasia of the hip (DDH) have undergone the AIO with the following advantages: 1. Avoidance of iliac crest deformity due to sacrifice of Anterior Superior Iliac Spine (ASIS), 2. Avoidance of postoperative lengthening of the ilium, 3. Less evidence of postoperative displacement loss according to direct contact between both iliac fragments, 4. Shorter time for bone union and earlier full weight bearing permission.

There have been no complications found so far.

The introduction and part of the results have already been reported^1).

In this report, more surgical details and knack of technique are mentioned with illustrations.
