椎体下的

In the upper part the vertebral body is hemispherical whereas in the lower part it is triangular.

上半部的椎体外形为半球形，而下半部为三角形。

Results: MR examination of bone contusion were mostly less than two weeks, but a few patients were longer than one year: STIR, TIWI were more sensitive lesion detection series in hone contusion (100% and 95.7%). Bone contusion mostly occur at knee, and lesions mainly distributed in the margin area of articular (69.8%), in superior portion of vertebral body(74.l%). Bone contusion following-up showed a line-like hyperostosis and osteosclerosis in contusion area. Histological manifestations of bone contusion were local trabecular micro fractures, edema, hemorrhage and injury of fat tissue.

结果：1多数骨挫伤MRI检查在两周内完成，少数病人时间超过1年；2检出骨挫伤敏感的MRI序列为STIR及T1W/I（100%及95.7%）；3膝关节是骨挫伤的好发部位，病灶主要分布于骨边缘区(69.8%)，在脊柱主要分布于椎体上缘终板下(74.1%)；4骨挫伤影像随访提小病变区出现线状骨质修复，骨髓水肿吸收；5骨挫伤病理为骨小梁显微骨折，骨髓水肿、出血和脂肪损伤。

Objective To provid the anatomic basis of Minimal invasion Operation for the lumbar disc herniation.

目的 通过对椎体后部结构的测量，为下腰椎后路微创手术提供解剖学依据。

Methods The clinical characteristics of 26 cases of cervicothoracic spine and spinal cord trauma were analyzed, which were performed with anterior subtotal vertebraectomy at C7, T1, C(subscript 6~7) or C7~T1 segment, bone graft and Orion anterior cervical locking plate fixation in cervicothoracic spine.

分析26例颈胸段脊柱骨折、脱位患者的临床表现；行颈胸段前路C7、T1、C(下标 6~7)或C7~T1椎体次全切除、植骨及Orion锁定型颈椎前路钢板固定术。

The current inestigation, therefore, seres as a basis for further ealuation of ertebral augmentation with calcium phosphate in fracture settings.

因此，对于骨折状况下磷酸钙作为椎体填充物的进一步评价，目前的研究，可以作为一个基础。

Objective: To provide anatomic data of vessels at the anterior aspect of lumber vertebrae for transperitoneal approach lumbar anterior minimally invasive surgery. Methods: This study investigated 30 human cadavers and 120 patients' magnetic resonance images, to study the major vascular anatomy of the anterior aspect of lumber vertebrae, and observe the relationship of the confluence of the common iliac veins with vertebral body or disc, as well the relationship of left iliac vein and L5~S1 disc.

目的：为经腹膜腰椎前路微创手术提供腰椎前方血管的解剖学依据；方法：选择30例防腐固定尸体标本及120例腰椎MRI断层数据，观察下腰椎区域髂总静脉的解剖学特点；根据腰椎前方血管的断层图片判断髂总静脉汇合点对应椎体的位置；L5~S1前方左髂总静脉对应椎间盘的位置。

Then , the 2 bone tamps are guided through the osteointroducers into the vertebral body , and inflated until expansion begins to occur in the weaker bone area previously seen on CT scan .

这种做法比较有创意，在没有提高医疗成本的前提下，单靠改进操作方法而提高了临床效果，从而使球囊扩张椎体后凸成形这项技术更加完善。

At the mid-thoracic and lower thoracic levels, significantly more vertebral rotation occurred under dorsal shear loads than under ventral shear loads.

在胸正中和下胸位置，背侧剪切载荷比胸侧剪切载荷会产生更明显的椎体旋转。
