Bladder exstrophy and cloacal exstrophy present challenging reconstructive problems. Traditionally, bilateral posterior iliac osteotomy has been performed in the majority of patients undergoing primary closure for these abnormalities. Recently, 2 anterior osteotomy approaches have been proposed: 1) incision of the ilium transversely above the acetabulum (transverse osteotomy) and 2) incision of the superior ramus of the pubis (superior ramus osteotomy). We devised a new anterior mid-iliac diagonal osteotomy that provides a more functional pelvic closure. To provide a fair comparison of the procedures we developed a pelvic exstrophy model based on data from a 3-dimensional computerized tomogram of a 3-year-old patient with classical bladder exstrophy. The different osteotomies were then performed on the model and the results were compared. Our new anterior mid-iliac diagonal osteotomy correction allowed the best surgical approach, provided the best correction of the flattened ilia bony deformities, was performed in the thinnest area of marrow bone and resulted in the best pelvic symmetry.
