Little information is available concerning the acetabular morphology in adults with a history of bladder exstrophy. We documented the pelvic anatomy in adult patients with bladder exstrophy who never had prior surgery. We retrospectively reviewed 31 patients (62 hips) seen from 1976 to 2003 for urologic problems related to bladder exstrophy without adjunctive pelvic osteotomy. There were 18 males and 13 females with an average age of 30 years at last followup. Radiographs at final followup were analyzed for lateral center-edge angle, acetabular index, head extrusion, hip center of rotation, acetabular version, retroversion index, sacral width, and interteardrop distance. Most hips (60 hips) had no arthritis. The average lateral center-edge angle, ace-tabular index, and head extrusion index were 32 degrees, 5.7 degrees, and 0.266%, respectively. Fifty-eight percent of hips had a retroverted acetabulum and 42% were neutral or anteverted. The interteardrop distance averaged 154 mm. Most patients will not have early arthritis develop, and the majority of patients (58%) have retroverted orientation of the acetabulum.
关于有膀胱外翻病史的成年人髋臼形态的信息很少。我们记录了从未接受过先前手术的膀胱外翻成年患者的骨盆解剖结构。我们回顾性分析了1976年至2003年期间因膀胱外翻相关泌尿系统问题就诊且未行辅助骨盆截骨术的31例患者（62髋）。其中男性18例，女性13例，末次随访时平均年龄为30岁。对末次随访时的X线片分析了外侧中心边缘角、髋臼指数、股骨头外移、髋关节旋转中心、髋臼前倾角、后倾指数、骶骨宽度和泪滴间距离。大多数髋关节（60髋）无关节炎。平均外侧中心边缘角、髋臼指数和股骨头外移指数分别为32°、5.7°和0.266%。58%的髋关节髋臼后倾，42%为中立位或前倾。泪滴间距离平均为154mm。大多数患者不会早期发生关节炎，且大多数患者（58%）髋臼呈后倾方向。
