A recent cadaveric study revealed that the tensed calcaneofibular ligament (CFL) lifts the peroneal tendons. This suggests that the CFL acts as a tensioner to transmit the contractile activity of the peroneal muscles effectively. However, the onset points of the lift-up and actual CFL-generated contact pressures against the peroneus brevis tendon (PBT) remain unclear. This cadaveric study aimed to elucidate the lift-up phenomenon through the quantitative measurement of changes in the contact pressure between the CFL and PBT under precise monitoring of the ankle position.
We performed a quantitative analysis of 11 cadaveric ankle specimens with a pressure-sensitive sensor under accurate three-axial joint angle monitoring using inertial measurement units. The output values from the pressure-sensitive sensor inserted between the CFL and PBT were measured at different inversion (INV) angles, converted into contact pressure values (mV), and statistically analysed.
Although the onset points differed across the samples, the contact pressure values of all samples showed a positive change as the INV angle increased. Friedman and post hoc Steel-Dwass tests revealed significant differences between INV 0° versus 10° ( < 0.01), 0° versus 15° ( < 0.001), 5° versus 10° ( < 0.05), 5° versus 15° ( < 0.001), and 10° versus 15° ( < 0.05). In addition, the sensor output values indicated an intraclass correlation coefficient (1, 1) of 0.90.
Our findings strongly suggest that INV enhances the tensioner effect of CFL. Specifically, an ankle with a relatively early onset point and high contact pressure may exhibit a superior tensioner effect and, through the control of peroneal tendons, potentially prevent an ankle sprain.

最近一项尸体研究表明，紧张的跟腓韧带（CFL）会抬高腓骨肌腱。这表明CFL起到张紧器的作用，以有效地传递腓骨肌的收缩活动。然而，抬高的起始点以及CFL对短腓骨肌腱（PBT）实际产生的接触压力仍不清楚。这项尸体研究旨在通过在精确监测踝关节位置的情况下，定量测量CFL与PBT之间接触压力的变化，来阐明抬高现象。
我们使用惯性测量单元在精确的三轴关节角度监测下，对11个尸体踝关节标本进行了压力敏感传感器的定量分析。插入CFL与PBT之间的压力敏感传感器的输出值在不同内翻（INV）角度下进行测量，转换为接触压力值（mV），并进行统计分析。
尽管各样本的起始点不同，但所有样本的接触压力值均随INV角度增加而呈正向变化。Friedman检验和事后Steel-Dwass检验显示，INV 0°与10°（<0.01）、0°与15°（<0.001）、5°与10°（<0.05）、5°与15°（<0.001）以及10°与15°（<0.05）之间存在显著差异。此外，传感器输出值表明组内相关系数（1,1）为0.90。
我们的研究结果有力地表明，内翻增强了CFL的张紧器效应。具体而言，起始点相对较早且接触压力较高的踝关节可能表现出更好的张紧器效应，并通过控制腓骨肌腱，有可能预防踝关节扭伤。
