The influence of the defect on the torsional stiffness and the stress distribution are calculated and analyzed by finite element method. The defect widths range from one-tenth of the femur outer diameter(0.1D) to (0.3D), and defect lengths range from 1D to 5D.

计算结果表明：骨缺损长度为D时，对股骨扭转刚度和剪应力分布的影响较小；骨缺损长度从2D增至4D时扭转刚度急剧减小，而且剪应力的最大值位于骨缺损中心。

The length of the screw is selected according to the transverse diameter of the calcaneocuboid articular surface, and the direction of the screw is determined according to the inner tilt angle.

跟骨骰骨关节面下方的骨量丰富，骨小梁致密，是螺钉植入的理想位置；应根据跟骨骰骨关节面的横径选择螺钉的长度，根据该关节面的内倾角决定螺钉的进钉方向。

Based on the hypotheses that the tissue fluid and the cell in lacuna are incompressible,and the tissue fluid could flow between the lacunar through the canalicular,the pressure on the cell was obtained.

基于骨陷窝中组织液和细胞具有的不可压缩性，以及组织液通过骨小管在骨陷窝之间的流动，得到了细胞所受压力的新的表达式。

Mallory trichrism staining exhibited light blue samples. Eight weeks following repair, CT showed round blunt defect edges in the coronal position, which had bony pustute connection with gel materials. Density at the defect region significantly increased. 3D reconstruction suggested that defects became small. After hematoxylin-eosin staining, abundant fibrous connective tissue appeared in defect regions, with bony tissues. Mallory trichrism staining revealed that maroon mature bone tissues were found, surrounded by light blue chondroid tissues. Twelve weeks following repair, coronal defect regions were filled with callus. 3D reconstruction showed that defects were repaired. Defect region and surrounding bony tissues had bony connection, with thick bone trabecula and mature Haversian system.

修复后8周，冠状位CT显示缺损边缘圆钝，与凝胶材料有骨性突起连接，缺损处密度增高明显，三维重建显示缺损范围较之前有所减小；标本苏木精－伊红染色后缺损部可见大量含血管成分的纤维结缔组织，有骨样组织结构形成，Mallory三色染色显示有褐红色成熟骨组织形成，其旁边有淡蓝色软骨样组织修复后12周，冠状位CT显示缺损区基本被骨痂填满，三维重建示缺损基本修复；缺损区域和周围骨组织形成骨性结合，骨小梁粗大，哈弗氏系统成熟。

讨论 FSS对成骨细胞功能的影响骨骼按遗传基因的调控建设骨骼的雏形，并在骨的生长发育中根据所承受载荷的需要对自身不断地进行改建与重塑，以试图实现用最小的骨量达到最大的骨强度，这就是骨的功能适应性。

ROM of the following construct fixation with Codman plates, Window plates with grafts and 1 mm shortened grafts were measured respectively, and the graft height were determined for each specimens by physical measurement of discectomy site.

将12例小牛颈椎标本随机分成两组，用生物力学测定仪测定正常颈椎C(下标 4/5)节段在前屈、后伸、左右侧屈、左右旋转时的三维运动范围，然后切除C(下标 4/5)椎间盘，制成损伤模型，测定植骨加钢板，植骨块缩短1mm加钢板固定后C(下标 4/5)节段的ROM，植骨块的长度根据测量椎间隙的高度而定。

CT displayed the structure of femoral head was vague. A piece of coloboma could be observed clearly on the cartilage of a femoral head. Medullary canal was almost filled with white adipose tissue. Osteoblasts and osteocytes decreased. Empty bone lacuna increased. Thrombus distributed widely in the bone tissue microcirculation.

MA组病理检查肉眼可见股骨头软骨面局部缺损，坏死面暴露，髓腔内大量脂肪组织堆积；光镜下成骨细胞、骨细胞均减少，空骨陷窝增多，微小血栓广泛分布，变形扩大的脂肪细胞挤压正常骨髓组织细胞，骨小梁变细破裂明显。

METHODS: From April 1998 to February 2002, 12 patients with micromandibular deformity associated with OSAS (aged 14-36 years, 7 females and 5 males) were treated. Invert "L" shape ramus osteotomy and inverted replantation of posterior segment of ramus were performed to reconstruct the TMJ with the jaw advancement and genioplasty at the same time in 7 cases; mandibular angle osteotomy, bone grafts and genioplasty in 3 cases; and the jaw advancement by ramus sagittal osteotomy and genioplasty in 2 cases of the first branchial arch syndrome. RESULTS: The follow-up period was 6 months to 4 years.

1998年4月～2002年2月，对12例(女7例，男5例，年龄14～36岁)伴有严重OSAS症状及张口度0～3.0 cm的小下颌畸形患者，7例采取下颌升支倒&L&形截骨、升支倒置颞下颌关节重建术的同时施行下颌体部前徙和颏成形术；3例在颞下颌关节重建术后进行下颌角部截骨、植骨下颌骨前徙术；2例施行下颌升支矢状劈开、下颌骨前徙术。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
