Abstract

INTRODUCTION

Prosthesis loosening is an alteration of the function and position of a total hip prosthesis with reference to the initial surgical moment. The main mechanism unanimously accepted for aseptic prosthetic losses at the level of the cup is represented by the biological mechanism.

MATERIAL AND METHOD

Experimental and virtual, interdisciplinary tools, techniques and methods were used to determine the behavior of the hip replacement prosthesis with the morcellated graft and the reconstruction net. Performing an orthopedic assembly with a morcellated bone graft and reconstruction net. An assembly was performed on a hip joint taken from an animal (cow). The biological material and the components of the prosthesis were prepared similarly to the revision prosthesis intervention. Experimental testing of orthopedic assembly with morcellated bone graft and reconstruction net. This assembly was tested on a universal machine to determine the maximum force at which it yields. This was 1790 Kgf, i.e. 17559 N. Virtual experimental testing of the hip joint with orthopedic revision assembly with a morcellated bone graft and reconstruction net for normal gait loading. The orthopedic assembly with the morcellated graft and the reconstruction net was reconstructed in the virtual environment. Normal load was used. Results maps were obtained.

CONCLUSIONS

Analyzing the results from the two tests, experimental and virtual, and important conclusions were drawn regarding this orthopedic assembly.

摘要

引言

假体松动是指全髋关节假体相对于初始手术时的功能和位置发生改变。髋臼水平无菌性假体松动被一致认可的主要机制是生物学机制。

材料与方法

运用实验和虚拟的跨学科工具、技术及方法，来确定带有碎骨移植和重建网的髋关节置换假体的性能。使用碎骨移植和重建网进行骨科组装。在取自动物（牛）的髋关节上进行组装。生物材料和假体组件的制备与翻修假体干预类似。对带有碎骨移植和重建网的骨科组装进行实验测试。该组装在万能试验机上进行测试，以确定其屈服时的最大力。此力为1790千克力，即17559牛。对带有碎骨移植和重建网的骨科翻修组装的髋关节进行正常步态负荷的虚拟实验测试。在虚拟环境中重建带有碎骨移植和重建网的骨科组装。使用正常负荷。获得结果图。

结论

分析实验和虚拟这两项测试的结果，得出了关于该骨科组装的重要结论。
