由于后踝骨折（PMF）时施加的力不同，骨折碎片之间矢状角（SA）的差异可能会影响踝关节的稳定性。但这方面研究较少，本研究的目的是探讨SA与PMF稳定性之间的关系。回顾性收集2014年1月至2022年11月120例PMF患者的影像学资料并进行重建。我们首先测量了SA、后碎片面积（PFA）和碎片面积比（FAR），分别重新分析了SA与PFA和FAR的相关性。为了更好地描述裂缝碎片的形态特征，我们进一步测量了碎片宽度直径比（FWR）、碎片长度比（FLR）、碎片高度（FH）、接触面积（CA），最后将这些数据带入SA与FAR的回归模型中起中介作用。 SA与PFA(s)呈负相关（r = −0.583，P < 0.001），回归方程s = −0.063SA + 3.066； SA与FAR呈负相关（r = −0.204，P< 0.05），回归方程FAR = −0.002SA + 0.198； FWR、FLR、FH、CA 和 SA 之间存在显着相关性（P < 0.05），FWR、FLR、FH 和 FAR 之间也存在显着相关性（P < 0.05）；进一步的中介作用分析表明FWR、FLR、FH在SA和FAR之间具有部分中介作用。随着SA的增加，PFA和FAR降低，因此SA越大是由于垂直剪力的作用，反映踝关节稳定性越高，同时骨折碎片的固定方法还应考虑FWR、FLR和FH。后踝骨折的 CT 扫描和 3D 重建。
Due to the different force exerted during the posterior malleolus fracture (PMF), the difference in sagittal angle (SA) between the fracture fragments may affect ankle stability. But this aspect is less well studied and the aim of this study was to investigate the relationship between SA and the stability of PMF. The imaging data of 120 patients with PMFs from January 2014 to November 2022 were collected retrospectively and reconstructed. We first measured SA, posterior fragment area (PFA) and fragment area ratio (FAR), reanalyzing the correlation of SA with PFA and FAR, respectively. To better describe the morphological characteristics of the fracture fragments, we further measured the fragment width diameter ratio (FWR), the fragment length ratio (FLR), fragment height (FH), contact area (CA), and finally carried these data into the regression model of SA versus FAR to conduct the intermediary role. SA was negatively correlated with PFA(s) (r = −0.583, P < 0.001), with regression equation s = −0.063SA + 3.066; SA was negatively correlated with FAR (r = −0.204, P < 0.05), with regression equation FAR = −0.002SA + 0.198; A significant correlation was found between FWR, FLR, FH, CA and SA (P < 0.05), as well as between FWR, FLR, FH and FAR (P < 0.05); Further intermediary role analysis showed that FWR, FLR, FH had a partial intermediary role between SA and FAR. As SA increased, PFA and FAR decreased, so the larger the SA was due to the effect of vertical shear force, reflecting higher ankle stability, meanwhile, FWR, FLR and FH should also be considered on the fixation method of fracture fragments.
