骨盆

OBJECTIVE: To construct a finite element model of pelvis after subtotal sacrectomy, and validate its effectiveness, which is supposed to be useful for evaluating reconstructions of sacroiliac joint.

目的：建立高位骶骨切除术后的骨盆有限元模型，并进行有效性验证，为骶髂关节重建方式的有限元评价提供平台。

In this experiment, we were successful to establish the finite element model of pelvis after subtotal sacrectomy. The calculated result was similar with the reference. The model could be used to evaluate different ways to reconstruct the sacroiliac joint.

成功建立了保留骶髂关节活动的骶骨次全切除术后骨盆的有限元模型，计算结果与文献中报道的结果较好地吻合，可认为有效，能够用于各种骶髂关节重建方式的有限元评价。

This has given rise to trocar-guided transvaginal surgical techniques using a transobturator or transgluteal approach, passing the mesh fixation arms through the arcus tendineus fascia pelvis or the sacrospinous ligaments.

曾经有人提到为了让生物材料提供预期的骨盆腔支持，他们必须固定在受影响的组织外面，这使得使用经闭孔或经臀肌方式的套管导引经阴道手术技术，从骨盆筋膜韧带弓或是荐脊韧带通过网线固定手臂。

The "daVinci representation"(right panel of Figure 6) is a comprehensive visual representation of the scoliotic spine that illustrates the orientation of the planes of maximum curvature of the 3 spine segments in the transverse view. The center of the circular plot is the point where the central hip vertical axis (CHVA, CHVA is a true vertical bisecting the bi-femoral head axis, often considered to represent the physiological center of balance of the spine-pelvic unit) intersects the transverse plane and every arrow radiating from the center represents a spine segment (PT, MT, and TL/L).

圆的圆心是位于髋中心的Z轴与横断面相交点(CHVA，CHVA是双侧股骨头连线重点的垂线，通常作为脊柱-骨盆单元生理平衡的中点)及每个箭头发自表示脊柱节段的中心。

Methods: 28 rabbits were divided into 3 groups (4 animals for every group). All animals were dissected to keep the spine and the pelvis, hip joint, the upper part of the femur, with the anterior and posterior longitudinal ligaments, intervertebral disk and psoas muscle, erector spinae, and supraspinal ligament attached to it.

取家兔12只，分3组，每组4只，解剖后保留枢椎以下完整之脊柱及骨盆、髋关节、上段股骨，不损伤脊柱前、后纵韧带、椎间盘及所附着之腰大肌，保留脊柱背侧的竖脊肌、棘上韧带，置于生物力学拉伸测试仪（日本岛津制作所产AGS-J系列）。

The spiral CT of three-dimensional SSD and VRT reconstruction provide more clear image on the details of pelvic tumors,which can stereoscopically,easily,understandably display the relationship between the lesion and surrounding structure,and the excisional range,so it can help clinical doctors for accurate diagnosis and making operation plan.

螺旋CT三维表面SSD及VRT图像清晰地显示了术前骨盆肿瘤的细节，以最易理解的形式立体直观地显示了病变及与周围结构的关系及手术应切除的范围，有助于术前正确诊断和制定手术计划，有效地减少术后局部复发。

Objective To summerize the experiences and lessons of diagnosis and treatment of unstable pelvic fracture and its complications.

目的 总结不稳定性骨盆骨折诊治的经验和教训。

The opioid receptor agonist at the supraspinal site failed to alter the pelvic nerve activity suggest that supraspinal endogenous opioid system does not act directly on the sacral preganglionic neurons, but indirectly through descending fibers on the interneuron at the level of afferent inputs in the sacral spinal cord.

由於注射此药物到侧脑室中，并不会对骨盆神经之活性造成影响，因此推论上脊髓部位的内吗啡系统，并不会直接影响副交感神经节前神经元之活性，其作用可能在中问神经元或膀胱的输入神经。

Objective: To study the difference of the pelvic stiffness of internal fixation methods by sacroiliac screws with anterior symphyseal plating for different displaced vertically unstable pelvic fracture.

目的：探讨垂直不稳定骨盆骨折在不同移位下行后环骶髂关节螺钉和前环钢板螺钉固定的稳定性差异。

Objectives: To report on the radiographic and clinical outcome of symphyseal plating techniques, with specific attention to the incidence of implant failure, reoperation secondary to implant complication, and ability to maintain reduction of the pelvic ring.

摘要目的：报道两孔及多孔耻骨联合钢板固定的放射学和临床效果，非凡关注植入物的失败率、因植入物并发症而再次手术情况，及其对骨盆环复位的维持能力。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
