METHODS: A thorough search was conducted across databases, including PubMed, Scopus, Cochrane library and grey literature. A total of 59 articles were identified, and after rigorous evaluation, six articles were included in the review.
RESULTS: The analysis underscores two principal findings. Firstly, the principal and accessory collateral ligaments exhibit consistent tension influenced by the MCP joint\'s position. This tension varies across different sections of the ligaments. Secondly, the ligaments\' interaction with the joint structure plays a pivotal role in defining the range of motion of the joint.
CONCLUSIONS: Preliminary findings from this review indicate that MCP joint collateral ligament tension varies with joint position. Increased tension in the principal collateral ligament during flexion and isometric behavior of its volar portion in extension are observed. The accessory ligament may tighten during extension. The shape of the metacarpal head appears to influence this tension. These insights, while informative, call for further detailed research to deepen our understanding of MCP joint mechanics.
方法:对数据库进行了彻底的搜索,包括PubMed,Scopus,科克伦图书馆和灰色文献。共确定了59篇文章,经过严格的评估,审查中包括六篇文章。
结果:分析强调了两个主要发现。首先,受MCP关节位置的影响,主韧带和副韧带表现出一致的张力。这种张力在韧带的不同部分之间变化。其次,韧带与关节结构的相互作用在确定关节的运动范围中起着关键作用。
结论:本综述的初步结果表明,MCP关节侧副韧带张力随关节位置的变化而变化。观察到屈曲过程中主侧副韧带的张力增加,并且其掌侧部分在伸展时的等距行为。副韧带可能在伸展期间收紧。掌骨头的形状似乎会影响这种张力。这些见解,虽然信息丰富,呼吁进一步详细的研究,以加深我们对MCP关节力学的理解。
