To determine the gender and age differences in posterior tibial tendon (PTT), flexor digitorum longus tendon (FDLT), medial malleolar groove (MMG), and posterior, anterior, and total posterior malleolus (PMP, APM, and TPM, respectively) and evaluate the use of these parameters for posterior malleolus plating.
Descriptive study.
Department of Radiology, Etimesgut Şehit Sait Ertürk State Hospital, Ankara, Turkey, from January to December 2020.
The magnetic resonance images (MRI) of the ankle were evaluated. PTT and FDLT thickness and width, MMG depth, width, length, and groove opening angle, and APM, TPM, and PPM length were measured. Receiver operating characteristic analysis was conducted to determine whether the variables differed between gender and age.
The study included 103 patients (61 women, 42 men). For gender discrimination, the sensitivity, specificity, and cut-off values were 78.6%, 72.1%, and 7.48 mm, respectively. For the PTT width: 76.2%, 77%, and 3.88 mm, respectively; for the PTT thickness: 85.7%, 86.9%, and 40.41 mm, respectively; and for the APM length, the APM, TPM, and PPM length measurements were statistically and significantly differed between the genders (p<0.001). The APM/PPM ratio was 0.47±0.057 mm in women and 0.47±0.060 mm in men, and TPM/PPM was determined as 0.55±0.604 mm and 0.56±0.657 mm. There was a statistically significant weak positive correlation among the age, MMG length, and FDLT width.
The groove depth and width, PTT and FDLT width and thickness, and TPM, PPM, and APM length can be used in gender prediction. The APM/PPM ratio can be calculated to determine the plating length in posterior malleolus fractures.

确定后胫肌腱（PTT）、趾长屈肌腱（FDLT）、内踝沟（MMG）以及后踝、前踝和总后踝（分别为 PMP、APM 和 TPM）的性别和年龄差异，并评估这些参数在后踝钢板固定中的应用。
描述性研究。
土耳其安卡拉埃特米兹古特沙伊特·埃尔图尔克州立医院放射科，2020 年 1 月至 12 月。
评估踝关节的磁共振成像（MRI）。测量 PTT 和 FDLT 的厚度和宽度、MMG 的深度、宽度、长度和槽口角度，以及 APM、TPM 和 PPM 的长度。进行受试者工作特征分析，以确定变量在性别和年龄之间是否存在差异。
该研究纳入了 103 名患者（61 名女性，42 名男性）。对于性别鉴别，敏感性、特异性和截断值分别为 78.6%、72.1%和 7.48 毫米。对于 PTT 宽度：分别为 76.2%、77%和 3.88 毫米；对于 PTT 厚度：分别为 85.7%、86.9%和 40.41 毫米；并且在 APM 长度方面，男女之间的 APM、TPM 和 PPM 长度测量值存在统计学显著差异（p<0.001）。女性 APM/PPM 比值为 0.47±0.057 毫米，男性为 0.47±0.060 毫米，TPM/PPM 为 0.55±0.604 毫米和 0.56±0.657 毫米。年龄、MMG 长度和 FDLT 宽度之间存在统计学上显著的弱正相关。
沟的深度和宽度、PTT 和 FDLT 的宽度和厚度以及 TPM、PPM 和 APM 的长度可用于预测性别。可以计算 APM/PPM 比值来确定后踝骨折的钢板固定长度。
