人们对小关节生物力学的研究越来越感兴趣。因此，对于计算机模拟研究，了解与小关节相关的感兴趣输出的模型可靠性水平非常重要。在这项工作中，进行了系统的审查有限元模型的多个层面的脊柱节段与小关节输出的利益。该综述集中于用于小关节建模的方法及其相关验证。从分析的110篇论文中，有18篇对小关节输出进行了一些验证。通过将输出与文献数据（计算值或实验值）进行比较来进行验证;主要缺点是，与计算值进行比较时，基线数据很少得到验证。分析的建模方法表明，似乎有一个妥协的几何形状和压缩的软骨行为的非线性之间的准确性。大多数模型使用关节处软骨层的软接触表示或包括线性弹性的软骨层。最令人担忧的是，软接触模型通常没有包含太多的信息的压力过封闭的法律。该综述表明，为了提高脊柱小关节输出的计算机模拟模型的可靠性，需要对用于小关节建模的方法进行更多的描述，并且需要对感兴趣的特定输出进行更彻底的验证，建议系统地共享验证研究的输入和输出数据。
There is an increased interest in studying the biomechanics of the facet joints. For in silico studies, it is therefore important to understand the level of reliability of models for outputs of interest related to the facet joints. In this work, a systematic review of finite element models of multi-level spinal section with facet joints output of interest was performed. The review focused on the methodology used to model the facet joints and its associated validation. From the 110 papers analysed, 18 presented some validation of the facet joints outputs. Validation was done by comparing outputs to literature data, either computational or experimental values; with the major drawback that, when comparing to computational values, the baseline data was rarely validated. Analysis of the modelling methodology showed that there seems to be a compromise made between accuracy of the geometry and nonlinearity of the cartilage behaviour in compression. Most models either used a soft contact representation of the cartilage layer at the joint or included a cartilage layer which was linear elastic. Most concerning, soft contact models usually did not contain much information on the pressure-overclosure law. This review shows that to increase the reliability of in silico model of the spine for facet joints outputs, more needs to be done regarding the description of the methods used to model the facet joints, and the validation for specific outputs of interest needs to be more thorough, with recommendation to systematically share input and output data of validation studies.
