骶骨

Methods A total of 158 cases of resection of sacral tumor were retrospectively analyzed and the problems related to anesthesia were summarized.

对158例次骶骨肿瘤切除重建手术麻醉中出现的相关情况进行回顾性分析，以此总结手术麻醉中应当注意的问题。

Methods 39 sacral fractures were retrospectively reviewed.

39例骶骨骨折， 37例行保守治疗，2例行手术治疗。

Objective To discuss the problems related to anesthesia for resection of sacral tumor so as to provide appropriate experience in treatment.

目的 对骶骨肿瘤切除重建手术麻醉中出现的各种相关问题进行探讨，以总结临床经验。

There is some evidence to suggest that sacral orientation can be a key player in revealing the etiology of spondylolysis.

有证据表明骶骨的方向在脊柱滑脱病因学中可能扮演重要角色。

Methods Thirty pathologically confirmed sacral tumors were studied by CT scan.

回顾分析30例经病理证实的骶骨肿瘤影像学特点。

Moreover, sacrectomy may cause pelvic instability that may necessitate additional surgery.

而且，骶骨切除引起的骨盆失稳，可能需要另外的手术。

Moreoer, sacrectomy may cause pelic instability that may necessitate additional surgery.

而且，骶骨切除引起的骨盆失稳，可能需要另外的手术。

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。

While shown to be curative, total sacrectomy can produce large osseous and soft tissue defects that lead to vertical and rotational instability, necessitating reconstructive surgery.

全骶骨切除尽管有治愈的可能，但会造成巨大的骨与软组织缺损，导致垂直和旋转的不稳定，从而需要进行重建手术。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
