生物力学

Methods 30 femurs were tested for bone mineral density,Singh index and biomechanical properties.

30侧股骨标本行骨密度与Singh指数测定，并行生物力学测试。

Objective: This experimental study is based on earlier animal and clinical experiment, drawn thinkings of combinations with two methods and pursued a synthesis method of high-efficiency, cheap and convenient calcium and exercise treatment. We adopt taking natural-clam's casing powder and preconcereted-intensity excises to intervene shape of osteoporosis in gelded rats, than we compare the indexes such as the biomechanics indexes of the right femur and the third lumbar vertebrae, the weight and uterus quotiety of rats before the experiment to these indexes after the experiment. We hope to find better and suitable way to prevent and treat the postmenopausal osteoporosis and offer reference for clinic.

目的 本实验的主要目的是在前期动物实验的基础上，引入两种方式联合干预的思维，立足于探求既高效又经济、方便的补钙剂加上与运动疗法相联合的方式，对切除雌性大鼠卵巢而复制成的骨质疏松症模型进行服用天然贝类蛤蜊壳粉，同时施以预定强度的运动刺激的方法，再通过试验前后大鼠体重、子宫指数的变化及大鼠股骨和椎体生物力学指标的对比变化进行分析，以期探索出防治绝经后骨质疏松症的更好的、更适宜于大众的手段；并为天然钙剂和运动联合作用防治PMOP提供参考。

For example, since biomechanics requires muscle force against a stationary object to produce bodily movement, muscle contractions must occur; however, the typical person overexerts himself on simple, preprogrammed movements, such as climbing stairs, because of a lack of efficient movement.

例如，生物力学要求肌肉通过对固定物体发力来推动身体的位移，肌肉收缩是必然的。

METHODS: Eight fresh patellae specimens were divided into two groups at random, AO steel wire group (n = 2) and absorbable tension band group (n = 6) to create models of transverse fractures, which were separately fixed by absorbable tension band, steel wire tension band + Kirschner wire to measure their biomechanics function. If fracture gap reached 1.0 mm, the fixation failed.

随机分成AO钢丝组2个和可吸收张力带组6个，制成横断骨折模型，分别用可吸收张力带、钢丝张力带加克氏针进行内固定，测定它们的生物力学性能，骨折端分离1.0 mm为固定失效。

Methods Twelve half pelvises were classified into 3 groups randomly.

笔者选用髋臼横断骨折常用的3种内固定方法进行生物力学稳定性比较。

The experimental method was improved, by using a ball to press the sclera samples, which were obtained nine months after surgery. The pretesting, relaxing and creeping experiments were carried out.

改进实验方法，采用球面致压拉伸巩膜的实验方法，对术后9月组上述5种兔眼巩膜试件进行预拉伸、应力松弛、蠕变的生物力学实验研究。

Methods: The tenderness of normal points in subjects with acute neck pain were firstly diagnosed with current diagnostic method, secondly were measured with tonic measurement system of local soft tissue, then whose stress-strain curves were analysized to find proper indexes reflexing the difference.

采用自制软组织张力测试系统，观察急性颈痛患者自身压痛点及无压痛点的力－位移曲线，分上颈椎、下颈椎及颈肩背部等三部位，对生物力学指标按照&压痛点&、&无痛点&配对比较。

OA was caused in the rabbit by resecting the cartilage between diaphsis and condyle of proximal tibia.

针对临床中大量的继发性膝关节OA病例，孟和教授强调了生物力学在病因学、病理学及治疗学中的重要地位：&尽管有酶类及免疫反应的参予降低了关节软骨的屈服强度，但要磨损到骨质外露却离不开应力的作用&。

Objective To study the biomechanical significance of hip resurfacing arthroplasty at the femoral side by finite element analysis.

目的 通过有限元分析探讨髋关节表面置换后股骨侧的生物力学意义。
