title: Comparison of posterior and anterior pelvic osteotomy for bladder exstrophy complex.
abstract: To compare the correction and maintenance of the pelvic ring after pelvic osteotomy in bladder exstrophy complex, we analyzed all cases performed at our institution. Posterior osteotomy was performed in six patients; anterior or combined osteotomy was performed in four patients. Patients who underwent posterior osteotomy had a mean pubic approximation of 37.3%. The mean was 62.8% in patients undergoing anterior or combined osteotomy. This difference was statistically significant (P<0.05 ). The mean recurrence of separation in pubic diastasis was 90.5% for posterior osteotomy and 41.6% for anterior or combined osteotomy. These results indicate that an anterior or combined pelvic osteotomy corrects and maintains the pelvic ring with a bladder exstrophy complex more effectively than a posterior pelvic osteotomy.
