Osteotomy and distraction of the anterior segment of the pelvic ring in epispadias repair: case report.

We report a new therapeutic approach for bladder exstrophy and epispadias in one case of failed epispadias repair. The width of the pelvis was measured by what we defined as the anteroposterior diameter (APD) on combined transverse computed tomography (CT) scan cuts of the pelvis. The APD was half the normal value in an incontinent patient with failed epispadias repair. He underwent a supraacetabular osteotomy of the pelvis with progressive anterior distraction of the anterior segment of the pelvic ring. Four months later, hardware was removed, and the APD was near normal value. Within 9 months of follow-up, the patient was dry day and night. We believe that in patients with failed exstrophy and epispadias repair, APD seems to be a predictive criterion for continence, and results of the reconstructive surgery with osteotomy should be improved by distraction of the anterior segment of the pelvic ring.
