Abstract：
The Achilles tendon (AT) is reportedly the most vulnerable to rupture at the midportion, a section of relative hypovascularity. It has been postulated that the twisted structure of this tendon may constitute a critical factor contributing to increased propensity to vascular compromise, decreased regenerative capacity, and rupture in the midsection of the AT. In this review, we will give an overview of the most relevant research on AT vasculature and twist, and delve into the interplay between the two elements in the context of AT disorders. The pertinent body of research suggests a considerable variability in tendon twist among individuals, which likely constitutes a determining factor in the extent to which vessels coursing along and between AT fibers are compressed during contraction-induced elongation of the tendon. Consequently, further research is necessary to investigate the precise association between tendon torsion and blood flow within the AT.
摘要：
据报道，跟腱（AT）在中部最容易破裂，血管相对不足的部分。据推测，这种肌腱的扭曲结构可能是导致血管受损倾向增加的关键因素，再生能力下降，并且在AT的中段破裂。在这次审查中,我们将概述有关AT脉管系统和扭曲的最相关研究，并在AT障碍的背景下深入研究这两个元素之间的相互作用。相关研究表明，个体之间的肌腱扭曲存在相当大的差异，在收缩引起的肌腱伸长过程中，沿着AT纤维和在AT纤维之间流动的血管被压缩的程度可能构成决定因素。因此,需要进一步的研究来研究肌腱扭转与AT内血流之间的精确关联。
