骶耻骨的

After the vital signs were stabili zed with reasonable wound care and 2 hours of fluid resuscitation, the patient r eceived a thorough debridement and the hip disarticulation and fixation of pubic symphysis.

其特点为耻骨联合广泛分离和骶髂关节破裂，伴有不同程度的软组织损伤，髂或股血管撕脱或闭塞，坐骨神经和股神经严重牵拉犤2犦。

Results:When unilateral anterior superior iliac spine loaded by transient stress,0-10 ms,stress distributed from posterior superior iliac spine to anterior superior iliac spine,and on the last 10 ms,there were greater stress distribution around cacroiliac joint,acetabulum and pubic branch.When unilateral positive backside of ilium loaded,between 0 ms and 20 ms,stress transmitted along vertical direction of ilium,and after 20 ms,there were greater stress distribution on cacroiliac joint,both pubic branch,ischium branch and acetabulum.

结果：冲击载荷作用于单侧髂前上棘时，0～10ms主要的应力沿髂后上棘到髂前上棘分布，在冲击后期10ms以后，骶髂关节、髋臼和耻骨支都会产生较大的应力分布；作用于单侧髂骨正后方部位时，0～20ms主要的应力沿髂骨纵行传导，应力分布并没有在冲击峰值10ms时达到最大，而是从20ms之后，应力开始向骶髂关节、双侧耻骨支、坐骨支以及髋臼等部位传导并可见到明显的应力分布。

The strain concentrated at two sides of the sacroiliac joints, and it was very small.

应变集中在两侧骶髂关节，绝对值很小，前方的耻骨联合处应变极小，可忽略不计。

Methods: Three out of eight pelvic specimens of cadavers were measured as normal group. then vertically unstable pelvic fractures were produced, and the biomechanical stiffness of internal fixation by sacroiliac screws with four hole LCDC symphyseal plates was tested and compared in the different reductions placement (low displace group and high displace group), the vertical and horizontal displacements of the sacroiliac joint and pubic symphysis were measured.

将8具尸体骨盆随机取3具做压力测试设为正常组，然后制成垂直不稳定骨盆骨折模型，骶髂关节和耻骨联合在移位0~4mm及移位8~12mm行后环骶髂关节螺钉和前环钢板螺钉固定，测量骶髂关节和耻骨联合的垂直和水平移位。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
