The aim of the present study was to investigate the anatomical and morphological characteristics and the maximum elongation of the calcaneofibular ligament (CFL) in cadavers. In a sample of 72 cadaveric lower limbs the mean values of length, width, thickness, and angle with the sagittal plane were recorded for the CFL. The mean ligament's length was 31.8 mm, and the mean width and thickness were 4.4 mm and 1.5 mm respectively. The mean angle with the sagittal plane was 51.11°. In 72.2% of the lower limbs studied, the ligament presented one band, while 22.2% and 5.6% of them were two-banded and three-banded respectively. A common origin with the anterior talofibular ligament (TFL) was found in 24 of the feet (33%). There were also 4 cases in which the anterior TFL was absent. Finally, we measured the maximal elongation of the ligament during extreme inversion and simultaneous dorsal flexion and found it to be 2.88 mm on average. We noticed and statistically verified that women presented a greater elongation compared to men. A precise knowledge of the origin, insertion, direction, and morphology of CFL is critical for ligament injuries in ankle sprains and during ankle reconstruction. Ligament elasticity plays an important role in the range of ankle motion and ligament shearing. Male and female ankle joints differ in several anthropometric characteristics and thus the genre differences in ligament elongation are of great interest.
本研究的目的是调查尸体中跟腓韧带（CFL）的解剖学和形态学特征以及最大伸长率。在72个尸体下肢样本中，记录了CFL的长度、宽度、厚度以及与矢状面的角度的平均值。韧带的平均长度为31.8毫米，平均宽度和厚度分别为4.4毫米和1.5毫米。与矢状面的平均角度为51.11°。在72.2%的研究下肢中，韧带呈现一条束带，而其中22.2%和5.6%分别为两条束带和三条束带。在24只脚（33%）中发现与距腓前韧带（TFL）有共同起点。也有4例距腓前韧带缺失的情况。最后，我们测量了韧带在极度内翻和同时背屈时的最大伸长率，发现平均为2.88毫米。我们注意到并经统计学验证，女性的伸长率比男性更大。准确了解CFL的起点、止点、方向和形态对于踝关节扭伤和踝关节重建时的韧带损伤至关重要。韧带弹性在踝关节活动范围和韧带剪切中起重要作用。男性和女性踝关节在一些人体测量学特征上存在差异，因此韧带伸长率的性别差异备受关注。
