To report our clinical experience in patients with bladder exstrophy. From 1994 to 2000, ten children were treated for bladder exstrophy at our hospital. Five innominate osteotomies were performed in 4 patients with bladder exstrophy. The other 6 children were treated with primary repair without osteotomy. All patients had at least 2 years of clinical follow-up. Each patient underwent an activity level, physical, radiographic, and continence evaluation. Bladder exstrophy was associated with short stature in our studies. Normal CE angle was noted in all patients, suggesting that the acetabulum coverage of femoral head does not decrease in this condition. The normal gait patterns of these patients showed successful skeletal adaptation. There was no association between the degree of continence and the distance of diastasis, although continence seemed better in the innominate osteotomy group.
