Background: The place of pelvic osteotomy in reconstructing bladder/ cloacal exstrophy has been debated for some time; the experience with 'combined' osteotomy in primary and re-operative exstrophy closure at this institution is presented, with a discussion of the historical and scientific place of osteotomy in managing this condition. Patients and methods: Sixty-eight patients had bilateral vertical and transverse iliac osteotomy between 1992 and 2003, and with outcome data available. Of 58 patients with classic exstrophy, eight were newborns, eight were deliberately delayed primary closures, 36 were re-operative after previous failed closure and six were bladder neck reconstructions where the bladder outlet was very wide, such that bony closure was felt necessary for successful bladder neck coaptation. Of 10 patients with cloacal exstrophy, nine were primary closures and one was a re-operative closure. Data were collected relating to age at closure, complications and continence outcome. Results: The mean (range) age (months) was 41 (5-179) for re-operative closures, 12.5 (3-32) for delayed primary closures, 64.1 (38-79) for bladder neck reconstruction, 51.4 (6-165) for cloacal exstrophy closure, and 15 (2-45) days for newborn exstrophy closure. There was a superficial wound infection in two patients, pin-site infection in one, loose pins in two, and two had transient femoral nerve palsy. In two patients the procedure failed and they required further re-operative closure with osteotomy. Sixteen patients are dry urethrally day and night, 12 have had and four are awaiting bladder augmentation, one has a colon conduit, and 35 are awaiting a definitive continence procedure. Conclusions: Osteotomy has a proven track record in the field of exstrophy reconstruction, and the benefit especially in re-operative closure is emphasized by the present results. The surgical morbidity with the 'combined osteotomy' is low, cosmetic results are excellent and the effect on success of closure is clearly advantageous.
