查询词典 proximal

They involve long tubular bones, pelvic, proximal femur, tibial plateau and calcaneum. Authors introduce their experience from their clinical practice which can benefit readers a lot.

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。

However, the stress load alters in the proximal femur following THA, leading to "adaptable bone reconstruction", which is characterized by thin cortical bone, decreased bone density, and bone loss surrounding prosthesis, in particular calcar femorale.

但是全髋关节置换后股骨近端应力负荷会发生改变，导致股骨近端的所谓"适应性骨重建"，其特点是皮质骨变薄，骨密度下降，引起股骨近端假体周围，尤其是股骨距区骨丢失。

Conclusion］1? It showes a higher stress dodge in the calcar femorale after using various kinds of prosthesis implantation? After using CFR/PSF of lower elastic modulus as handle, the stress dodge rate is lower in femur, but the interface stress is higher, and this is the main factor and reason for the prosthesis loosening? 2? The stress force rule meets the design principle that the stress force decreases gradually in the bone interface from proximal to distal? The stress value in different combination of same prosthesis handle has no significant difference, that showes mechanical factor is not the main standard for selecting prosthesis combination?

［结论］ 1、各种假体植入后均在股骨距处形成较高的应力遮挡，而用弹性模量较低的CFR/PSF作为柄，其股骨相应区域的应力遮挡率较低，但股骨相应界面应力较大，而界面应力过大是产生假体微动主要因素。2、股骨界面从近端至远端呈逐渐增高趋势的应力规律符合该假体的设计原理；相同假体柄的不同组合其股骨和髋臼相应界面应力值无明显差别，实验表明力学因素并不是选择假体组合的主要标准。

［Objective］ To observe the clinical experience of artificial caput humeri substitution to senile humerus proximal fracture.

：［目的］介绍高龄肱骨近端骨折患者人工肱骨头置换的临床经验。

The cardo is the first or proximal piece, and, in many insects, is the only portion directly attached to the head

轴节是第一个或最近体躯的骨片，在许多昆虫中是与头部直接相连的唯一部分。

Results In the distal two - thirds of the upper arm, branches of the median nerve constantly formed three fascicular groups. The anterior part of nerve trunk hosted branches to the pronator teres and the flexor carpi radialis. The posterior part of nerve trunk contained the anterior interosseous nerve and branches to the palmaris longus muscle. Branches to the hand and to the flexor digitorum superficialis which was the main trunk of the median nerve at the proximal forearm were grouped to form the middle part.

结果 在臂中、下段，正中神经的分支恒定地组成3个神经束组：旋前圆肌肌支和桡侧腕屈肌肌支束组在神经干的前方，骨间前神经和掌长肌肌支束组在神经干的后方，中间束组是由指浅屈肌肌支和手部分支组成的正中神经前臂主干的近段。

This can be achieved by thumb occlusion of the distal end, retrograde cement insertion with a gun and the use of a proximal seal.

这可以用拇指闭塞其远端，用骨水泥枪将骨水泥逆行注入，并使用近端封闭。

In addition, spermiogenesis includes chromatin condensation, migration of the cytoplasm and mitochondria to the caudal pole of the nucleus, formation of a moderate axial nuclear fossa containing the proximal centriole and part of the distal centriole and presence of a short cytoplasmic canal separating mitochondria from the flagellum.

另外，精子发生过程中还包括染色质浓缩，细胞质和线粒体向细胞核的尾端迁移，在核的后端中轴位置上形成中等大小的核后凹，近端中心粒和远端中心粒的一部分嵌在核后凹之内，短的胞质内陷管将线粒体与鞭毛分隔开。
