The aim of this study is to reveal the morphometry of the distal tibia and posterior malleolus and to generate morphometric reference data for the tibial component of total ankle prosthesis.
This study was performed on 121 human dry tibiae (47 right, 74 left). The morphometric measurements of distal tibial structures, tibial length and the distance between the medial and posterior malleolus were measured in this study. Measurements on 44 tibiae were repeated three times and averaged for minimizing intra-observer error.
The tibial length was found 34.19 ± 2.31 cm. Mean values of width of fibular notch at tibial plafond and 10 mm proximal to the tibial plafond were 25.71 ± 2.44 mm and 17.81 ± 2.46 mm, respectively. Mean depth of fibular notch at tibial plafond and 10 mm proximal to the tibial plafond were 3.60 ± 1.04 mm and 3.37 ± 1.24 mm, respectively. Mean height of fibular notch was found 48.21 ± 10.51 mm. Mean width and height of medial malleolus were 25.08 ± 2.13 mm and 14.73 ± 1.85 mm, respectively. Mean width and length of tibial plafond were 27.71 ± 2.74 mm and 26.96 ± 2.62 mm, respectively. Mean values of width and height of posterior malleolus were measured 21.41 ± 3.26 mm and 6.74 ± 1.56 mm, respectively. Mean distance between medial and posterior malleolus was found 37.17 ± 3.53 mm. Mean width and depth of malleolar groove were 10.26 ± 1.84 mm and 1.73 ± 0.75 mm, respectively. The mean intra-class correlation values were found between the 0.959 and 0.999.
Knowing the distal tibial morphometry is crucial for designing convenient ankle replacement implants for Turkish population. To our knowledge, this study is the first in the literature that identifies posterior malleolar morphometry on dry tibiae. We believe that this study will make a significant contribution to the literature about distal tibial morphometry and especially the posterior malleolus and the data of our study can be used for designing total ankle prosthesis in Turkish population.
本研究旨在揭示胫骨远端和后踝的形态，并为全踝关节假体的胫骨部件生成形态学参考数据。
本研究共纳入 121 例成人干胫骨（47 例右侧，74 例左侧）。本研究测量了胫骨远端结构、胫骨长度以及内踝和后踝之间的距离等形态学测量值。其中 44 例胫骨的测量值重复测量 3 次，取平均值以最小化观察者内误差。
胫骨长度为 34.19±2.31cm。距胫骨平台 10mm 处胫骨平台下腓骨切迹的宽度和 10mm 处的平均值分别为 25.71±2.44mm 和 17.81±2.46mm。距胫骨平台 3.60±1.04mm 和 3.37±1.24mm 处的腓骨切迹深度平均值分别为 3.60±1.04mm 和 3.37±1.24mm。腓骨切迹的平均高度为 48.21±10.51mm。内踝的平均宽度和高度分别为 25.08±2.13mm 和 14.73±1.85mm。胫骨平台的平均宽度和长度分别为 27.71±2.74mm 和 26.96±2.62mm。后踝的平均宽度和高度分别为 21.41±3.26mm 和 6.74±1.56mm。内踝和后踝之间的平均距离为 37.17±3.53mm。距骨槽的平均宽度和深度分别为 10.26±1.84mm 和 1.73±0.75mm。组内相关系数的平均值在 0.959 到 0.999 之间。
了解胫骨远端的形态学特征对于设计适合土耳其人群的踝关节置换植入物至关重要。据我们所知，这是文献中首次对干胫骨的后踝形态进行研究。我们相信，这项研究将对胫骨远端形态学特别是后踝的文献做出重要贡献，并且我们研究的数据可用于设计土耳其人群的全踝关节假体。
