[Bladder exstrophy--anterior osteotomy of the pelvis--a new surgical technic for facilitating stabilization of the pelvis and abdominal closure].

The reconstruction of a stable anterior pelvic ring and the tension-free soft tissue closure is the key to a successful reconstructive surgery of the ectopic bladder. Instead of the commonly practised iliac osteotomy to achieve this goal we postulate the bilateral anterior osteotomy of the superior ramus of the pubic bone. The operative technique of this new method is described. The early results of four cases are discussed.
