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。

Objective: To investigate the therapeutic effect of Zhengqingfengtongning Injection into sacroiliac joint on treating patients with ankylosing spondylitis.

目的 观察骶髂关节注射正清风痛宁注射液治疗强直性脊柱炎骶髂关节炎的临床疗效。

BACKGROUND: Iliosacral screw fixing the sacroiliac joint after reduction can provide the stability of the pelvis.

背景：骶髂螺钉直接固定复位后的骶髂关节，可提供足够的骨盆稳定性，其生物力学稳定性优于其他常用的内固定。

OBJECTIVE: By studying the adult pelvic posterior ring CT measurement of the parameters of screw fixation of the iliosacral joint to provide related morphological data for the application of iliosacral screw fixation in iliosacral, and to explore the variability of the parameters.

目的：通过对成人骨盆后环的CT测量，为临床用骶髂螺钉固定骶髂关节提供形态学依据，并探讨钉道参数的变异性相关因素。

BACKGROUND: The entry point and direction of screw, iliosacral screw length, S1 pedicle screw shape and iliosacral joint adjacent structure understandings are key factors for successful iliosacral screw fixation.

背景：正确地选择进针点、进针方向和骶髂螺钉长度，以及对S1椎弓根形状和骶髂关节毗邻结构解剖的了解成为骶髂关节螺钉置入成败的关键。

Objective Creating a 3D finite element model of a full pelvis with sacroiliac joint fracture. Comparing the biomechanical properties of the model where the fracture part was fixated by using a new sacroliliac anatomy type Bar-plate internal fixation system to iliosacral screw fixation and front reconstruction plate fixation.

目的 建立使用新型的骶髂关节解剖型棒-板内固定系统对骶髂关节骨折脱位进行固定的三维有限元模型，并与骶髂关节螺钉、和前路重建钢板固定进行对比，验证和分析其力学性能。

Then, one side of sacroiliac joint related ligaments was deleted to simulate the case of sacroiliac joint fracture. Using a new sacroliliac bar-plate internal fixation system with anatomic plate to fix the fracture part, and the comparing models using iliosacral screw fixation and front reconstruction plate fixation were also generated. Finally, all models were simulated under same loading conditions.

去掉模型一侧的骶髂关节韧带群模拟骨折脱位，使用新型的SABP内固定系统进行固定模拟，同时分别使用骶髂关节螺钉和前路重建钢板固定建立对比模型，进行加载计算，分析受力情况。

40 cases of imitated adult patients with ankylosing spondylitis underwent routine intersect CT scan and high-resolution lamellar multislice spiral CT scan. The CT images and ranking of sacroiliitis were analyzed respectively, following the CT-guided piqure biopsy on cacroiliac joint. CT result was contrasted with pathology result.

对40例临床拟诊成人型强直性脊柱炎的患者进行常规横断CT扫描及多层螺旋CT薄层高分辨率扫描，分别对骶髂关节炎的CT表现及分级进行分析，并在CT引导下对该组病人进行骶髂关节穿刺活检，将CT结果分别与病理结果相对比。

Objective: To analyze the clinical characteristics of diagnosis and therapy of pyogenic sacroiliitis. Methods: 4 cases were analyzed retrospectively and reported; and related literatures were reviewed.

目的：回顾分析4例误诊为强直性脊柱炎的化脓性骶髂关节炎的病例，探讨化脓性骶髂关节炎的临床表现、诊断、治疗方法。

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。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
