Iliac Wing Osteotomy for the Closure of Pelvis in the Treatment of Bladder Exstrophy in the Neonate

Abstract

Classic bladder exstrophy is a rare disorder involving an externalized bladder through an associated pelvic diastasis. Difficulty of closure of pelvic diastasis is often encountered following urological reconstruction. Traditionally, an anterior innominate osteotomy is performed to increase pelvic volume, allowing closure of the rudimentary pubic symphysis and anatomical reduction of pelvic contents; however, this procedure can be technically difficult and has associated morbidity. We describe a novel technique of bilateral iliac wing osteotomies to achieve the same function that has not been described previously in the literature.
