骨端

At day 3, 6, 9, 14, 28, 42 and 56, five rabbits were selected from every group randomly and were killed by aeroembolism respectively. Their radius were taken out and the left one was taken as the research object. Immunohistochemistry stain and in situ hybridization stain were performed to examinate the VEGF and VEGF mRNA expression in the haematoma, fibrous callus and soft callus.

分别于术后3，6，9，14，28，42，56 d每组随机处死5只家兔，取左侧桡骨标本作为观察对象，通过免疫组化和原位杂交方法检查骨折端血肿、纤维骨痂和软骨骨痂中VEGF及VEGF mRNA表达。

While in this study, 2 week old Kunming mouse were killed by cervical dislocation. The long bone was collected on the super clean blench through sterile method, then periosteum and epiphyses were discarded.

另外，试验采用2周龄的昆明小鼠，拉颈处死，在超净工作台内无菌分离长骨，剔除骨周组织和骨骺端。

Seeral types of calcar replacement femoral components, as illustrated in Fig. 7-33 , are aailable for patients with loss of arying amounts of the proximal femur in lieu of the use of bone grafts.

如图7－33所示，几种带股骨距的股骨置换假体可用于股骨近端有不同程度骨缺损的病人，以替代骨移植。

On the fracture section, three strain gauges were put above the pins of groups fixed with external fixator. The gauges were recorded when the femurs were loaded vertically. Results (1) The compressive trabeculae and femoral calcar in the femoral neck region are the main load-bearing construction. The contract of the abductor muscle can protect the hip joint. When the model femur was abducted in small degree (10-30°), the stress improved gradually with the abductor angle. But adduction of the model will gradually decrease the stress in that area. When external violence was put on it, the main stress distribution was on the upper femur, which was in the middle and lower part of the femoral neck and between greater trochanter and lesser trochanter.

同时在④⑤两组又应用电阻应变片贴于断端间的三枚斯氏针上方以测定钢针上的应力与应变结果(1)股骨颈处的压力骨小梁和股骨距是重要的承载结构；载荷的传导主要通过压力骨小梁和股骨距由股骨颈区传至股骨干的中下1/3处；外展肌力的收缩对髋关节有一定的保护作用；在小角度外展实验中（10-30°）股骨颈区的应力递增，超过30°时股骨颈区的应力又逐渐减小，但在内收实验中随角度增大股骨颈处应力呈递减趋势；当外界暴力作用时，应力主要集中在股骨上段，即股骨颈中下段和大小转子处及其之间。

Laboratory proof was provided for the structural and functional changes of Hallux Valgus before and after the operation.

方法1。在临床上选取行小切口第一跖骨远端截骨手术的拇外翻患者56例111足，在术前及术后3个月拍摄足负重正位X线片；选取正常人9例18足作为对照组。

This design feature has been associated with early deelopment of osteolysis about the tip of the stem despite bone ingrowth proximally.

该设计特征与近端骨长入良好而柄末端周围早期发生的骨溶解有关。

Dry virgin surface for cementation proximally and distal press-fit, with limited compromise of the remaining distal femur.

干燥纯净的表面，用于骨水泥近端和远端匹配，剩余股骨远端有限的影响。

Made hook????pin and sutural pin were used to suture the ACL by bidirectional 'U' shape suturation. The silk was fixed on the end point of tibia through anterior tunnel of tibial tuberosity.

关节镜探查膝关节、修整ACL残端，使用自制钩针和缝合针，双向&U&形缝合ACL断端，缝线经胫骨结节前骨隧道固定ACL于胫骨端止点。

Methods Knee joint was examined with arthroscopy and the remanant end of ACL was repaired. Then self made hook pin and sutural pin were used to suture the ACL by bidirectional 'U' shape suturation. The silk was fixed on the end point of tibia through anterior tunnel of tibial tuberosity.

关节镜探查膝关节、修整ACL残端，使用自制钩针和缝合针，双向&U&形缝合ACL断端，缝线经胫骨结节前骨隧道固定ACL于胫骨端止点。

METHODS: The articular surfaces of the proximal ulna and cortex of horse ulnas were sawn to expose the trabecular bone, and only 15 cm proximal ulna was retained.

将40根马尺骨近端关节面及皮质锯除，使其正好暴露骨小梁面，保留近端15 cm锯除远端。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
