骨盆

Method］Ten adult mixed breed dogs without significant individual difference were made transverse fracture at bilateral iliopectineal crest 1.5 cm above the dome of acetabulum, which were fixed with ATMFS or steel plate respectively. The animals were sacrificed and specimens were procured at 2,4,6,8 and 12 weeks after operation.Samples from the fracture gaps were investigated by histology of HE and Masson staining,image pattern analysis of new bone formation.

方法］选用10只成年杂种家犬，双侧髋臼臼顶上方1.5 cm处横形截骨，分别采用ATMFS(骨盆髋臼三维记忆内固定系统)前柱固定器和5孔重建钢板内固定，于术后2、4、6、8、12周处死动物取材，行HE染色、Masson三色法染色组织学检查，图像分析新骨形成积分光密度值，研究不同应力作用模式下的骨盆骨折愈合情况。

OBJECTIVE: To explore the clinical effects of percutaneous iliosacral articulation screws and pelvis external fixation in the treatment for Tile C type pelvic fracture.

目的：观察经皮骶髂关节空心螺钉置入联合骨盆外固定架治疗C型骨盆骨折的临床疗效。

METHODS: From January 2001 to December 2008, 87 cases of Tile C type pelvic fracture were treated with the percutaneous iliosacral articulation screws and pelvis external fixation, and 39 cases treated through the anterior and/or posterior approach were selected as control group.

选择2001-01/2008-12广东省人民医院骨科收治采用经皮骶髂螺钉固定技术治疗的不稳定型骨盆骨折患者48例作为实验组。收集同期广东省人民医院科骨科收治行开放前路和/或后路手术治疗的不稳定型骨盆骨折患者39例作为对照组。

With age, the GL location regarding the heels remained constant, while the pelis moed posteriorly toward the heels and underwent a small retroersion.

随着年龄增长，关于脚后跟的重力线位置保持不便，但是骨盆朝着脚后跟向后移动并呈现轻微的后倾表现（即日益增加的骨盆倾斜度）。

The author reviews the recent advance in constructions for intact pelvis' model, the defect model after sacrectomy, and the model after reconstructing lumbosacral spine to give a general summarization.

本文综述了近年来完整骨盆及骶椎切除后的缺损骨盆有限元模型、骶椎切除后重建结构有限元模型的建立及其研究进展。

METHODS: Two three-dimensional finite element pelvis models were established:① an intact pelvis model,② a defective pelvis model on which subtotal sacrectomy was performed cephalic to the S1 neural foramina.

分别构建完整骨盆和经S1神经孔上缘水平施行骶骨次全切除术后的缺损骨盆的三维有限元模型。

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。

Clinically, iliac screws have demonstrated decreased rod breakage rates, and better correction of pelvic obliquity than unthreaded rods, but several modern methods of iliac fixation have not been compared.

临床上，髂骨棒被证明可以减少棒的断裂，并且比螺纹杆能更好的矫正骨盆倾斜，但几个现代的髂骨内固定方法在矫正骨盆倾斜方面没有进行比较。

Methods Passing through the measurement of anteverted and abducted angels of acetabula in positive radiograms of 40 hip joints, compared with the practical values of anteverted and abducted angels of pelvis specimen,demonstrating the accurency of these kinds of measurement.

方法通过20具(40髋)骨盆标本髋关节正位X线片髋臼前倾角、外展角的测算值与骨盆标本髋臼前倾角、外展角的实际值相比较，以证明该测算方法的准确性。

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）。
