Conclusions In principle, combined or extended ilio-inguinal approach should be reserved for the delayed acetabular fractures with the exception of simple fractures of posterior wall or/ and posterior column, anterior wall and anterior column which can be managed by a single approach. 结论除单纯的后壁或/和后柱、前壁与前柱骨折选择单一的入路外,对于陈旧性髋臼骨折原则上采用前后联合入路或延长的髂腹沟入路;
