Abstract

Whether the lateral ankle ligaments contribute to syndesmotic stability is still controversial and has been the subject of frequent research recently. In our study, we tried to elucidate this situation using the finite element analysis method. Intact model and thirteen different injury models were created to simulate injuries of the lateral ankle ligaments (ATFL, CFL, PTFL), injuries of the syndesmotic ligaments (AITFL, IOL, PITFL) and their combined injuries. The models were compared in terms of LFT, PFT and EFR. It was observed that 0.537 mm LFT, 0.626 mm PFT and 1.25° EFR occurred in the intact model (M#1), 0.539 mm LFT, 0.761 mm PFT and 2.31° EFR occurred in the isolated ATFL injury (M#2), 0.547 mm LFT, 0.791 mm PFT and 2.50° EFR occurred in the isolated AITFL injury (M#8). The LFT, PFT and EFR amounts were higher in the both M#2 and M#8 compared to the M#1. LFT, PFT and EFR amounts in M#2 and M#8 were found to be extremely close. In terms of LFT and PFT, when we compare models with (LFT: 0.650 mm, PFT: 1.104) and without (LFT: 0.457 mm, PFT: 1.150) IOL injury, it is seen that the amount of LFT increases and the amount of PFT decreases with IOL injury. We also observed that injuries to the CFL, PTFL and PITFL did not cause significant changes in fibular translations and PFT and EFR values show an almost linear correlation. Our results suggest that ATFL injury plays a crucial role in syndesmotic stability.

踝关节外侧韧带是否有助于联合韧带的稳定性：一项有限元分析研究。

踝外侧韧带是否有助于联合韧带的稳定性仍然存在争议，并且是最近频繁研究的主题。在我们的研究中，我们试图使用有限元分析方法来阐明这种情况。建立了完整的模型和13个不同的损伤模型，以模拟踝外侧韧带（ATFL、CFL、PTFL）的损伤、联合韧带（AITFL、IOL、PITFL）的损伤及其复合损伤。从LFT、PFT和EFR三个方面对模型进行了比较。观察到0.537 mm LFT，0.626 mm PFT和1.25°EFR发生在完整模型（M#1）中，0.539 mm LFT，0.761 mm PFT和2.31°EFR发生在孤立的ATFL损伤中（M#2），0.547 mm LFT，0.791 mm PFT和2.50°EFR发生在孤立的AITFL损伤中（M#8）。与M#1相比，M#2和M#8中的LFT、PFT和EFR量更高。发现M#2和M#8中的LFT、PFT和EFR的量非常接近。就LFT和PFT而言，当我们将模型与（LFT:0.650 mm，PFT:1.104）和不带（LFT:0.457 mm，PFT:1.150）IOL损伤，可见LFT的量随着IOL损伤而增加，PFT的量减少。我们还观察到，CFL、PTFL和PITFL的损伤不会导致腓骨平移的显著变化，PFT和EFR值显示出几乎线性的相关性。我们的研究结果表明，ATFL损伤在联合韧带的稳定性中起着至关重要的作用。
