Abstract

Purpose: 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.

Methods: 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.

Results: 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.

Conclusions: 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.

胫骨远端和后踝骨的形态测量及其对全踝关节假体的临床意义。

目的：本研究旨在揭示胫骨远端和后踝骨的形态测量，并为全踝关节假体的胫骨组件生成形态测量参考数据：本研究对 121 块人体干胫骨（右侧 47 块，左侧 74 块）进行了测量。本研究测量了胫骨远端结构、胫骨长度以及内侧和后踝骨之间的距离。对 44 块胫骨重复测量三次并取平均值，以尽量减少观察者内部的误差：胫骨长度为 34.19 ± 2.31 厘米。胫骨平台处和胫骨平台近端 10 毫米处腓骨切迹宽度的平均值分别为（25.71 ± 2.44）毫米和（17.81 ± 2.46）毫米。胫骨平台处和胫骨平台近端10毫米处的腓骨切迹平均深度分别为（3.60±1.04）毫米和（3.37±1.24）毫米。腓骨切迹的平均高度为（48.21 ± 10.51）毫米。内侧踝的平均宽度和高度分别为（25.08 ± 2.13）毫米和（14.73 ± 1.85）毫米。胫骨平台的平均宽度和长度分别为（27.71 ± 2.74）毫米和（26.96 ± 2.62）毫米。后臼壁宽度和高度的平均值分别为（21.41 ± 3.26）毫米和（6.74 ± 1.56）毫米。踝内侧与踝后之间的平均距离为（37.17 ± 3.53）毫米。踝沟的平均宽度和深度分别为（10.26 ± 1.84）毫米和（1.73 ± 0.75）毫米。平均类内相关值介于 0.959 和 0.999 之间：了解胫骨远端形态对于为土耳其人设计便捷的踝关节置换假体至关重要。据我们所知，这项研究是文献中首次对干胫骨后臼齿形态进行鉴定。我们相信，这项研究将对有关胫骨远端形态测量，尤其是踝后臼形态测量的文献做出重大贡献，我们的研究数据可用于设计土耳其人的全踝关节假体。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
