摘要

本文提出了一个应用Burmester的圆形理论,以确定最佳的机制,用于复制运动的胫骨相对于股骨。这项研究的出发点是研究一种外部固定架,以一种与实际患者的解剖结构物理相容的方式引导胫骨的运动,以便在关节重建手术后牢固地引导两块骨头,同时避免关节表面之间的任何接触。生理数据由其他论文的研究确定。然而,在最初的研究阶段,我们的想法是确定现有的四杆连杆的最佳位置,为骨科导师生产,没有任何尝试合成一个特别的连杆。在这次手术中使用伯梅斯特理论的想法实际上是一个古老的想法,但以前的尝试都不成功。当然,所需的四杆连杆也必须小,以适应外部固定架。研究的结果非常令人满意,因为有可能确定一种机制,当施加的运动必须使两块骨头保持至少一毫米的距离时,它允许相对运动的误差在毫米的数量级上。因此,两根骨头永远不会受压,而韧带的轻微拉扯将永远存在。使用该方法,还确定了不同人类类型的典型四杆连杆。

Use of Burmester’s Circular Theory in the Determination of the Optimal Four-Bar Link Reproducing Actual Tibia-Femur Relative Motion
The paper presents an application of Burmester’s circular theory to the determination of the optimal mechanism used to reproduce the motion of the tibia with respect to the femur. The research takes its start from the idea of studying an external fixator to guide the motion of a tibia in a way physically compatible to the actual patient’s anatomy, in order to firmly guide the two bones after, for instance, joint reconstructive surgery, while avoiding any contact between the articular surfaces. The physiological data were determined in researches presented in other papers. However, in the initial research phases the idea was to determine the best position of an existing four-bar link, produced for an orthopaedic tutor, without any attempt at synthesising an ad hoc one. The idea of using Burmester’s theory in this operation was in reality an old one, but previous attempts were not successful. Naturally, the required four-bar link had also to be small in order to fit on the external fixator. The results of the research are extremely satisfactory, since it was possible to determine a mechanism which allows relative motion with errors in the order of fractions of millimetres, when the imposed motion had to keep the two bones separated by a minimum of one millimetre. As a consequence the two bones will never go in compression, while a gentle pulling of the ligaments will always be present. Using the approach, typical four-bar links for different human typologies were also determined.
