摘要

骨软骨疾病发生在马腕骨的所有骨骼和软骨内,可导致运动功能丧失,偶尔还会导致灾难性的损伤,需要安乐死。导致这种伤害的压力的强度和方向是未知的。关节建模是人类骨科研究中常用的一种技术,它允许研究人员确定关节的内应力。通过使用计算机模型,可以模拟各种情况,如韧带损伤,并确定由此产生的关节表面应力的变化[1]。本研究的目的是通过实验获得马腕骨桡骨远端关节面、桡骨近端和远端以及第三腕骨近端关节面的精确定量接触面积数据。这些数据为马腕骨提供了规范的接触和软骨厚度值,这将有助于将该关节作为骨关节炎研究的大型动物模型。此外,这些实验数据将作为开发和校准马腕骨全关节计算机模型的基础。

Precise Quantitative Models of the Equine Articular Carpus Anatomy and Contact Areas
Osteochondral diseases occur within ail bones and cartilages of the equine carpus and can lead to loss of athletic use and occasionally catastrophic injury that necessitate euthanasia. The intensity and direction of stresses that lead to such injuries are unknown. Joint modeling is a commonly used technique in human orthopaedic research that allows investigators to determine the internal stresses of joints. Through the use of computer models, various scenarios, such as ligament damage, can be simulated and changes in the resulting joint surface stresses determined [1]. The purpose of this study was to experimentally obtain precise quantitative contact area data of the articular surfaces of the distal radius, the proximal and distal aspects of the radial carpal bone and the proximal aspect of the 3rd carpal bone of the equine carpus. These data provide normative contact and cartilage thickness values for the equine carpus that will facilitate the use of this joint as a large animal model for osteoarthritis studies. Furthermore, these experimental data will serve as the basis for the development and calibration of an equine carpus whole joint computer model.
