Abstract：
The present study was to determine the characteristics of the ankle skeletal structure in patients with talus Hepple V type. We conducted a retrospective study on the skeletal structure of the talus in 110 patients with Hepple V osteochondral lesions of the talus and in control participants. The radiographic measurements taken include the following: in the coronal plane - depth of talus frontal curvature, length of the lateral and medial malleolus; in the sagittal plane - radius and height of talus, angle of tibial lateral surface, tibiotalar sector, and vertical neck angle. The osteochondral lesion of the talus showed a significantly larger mean radius (mean ± SD, 21.4 ± 2.5 mm; p < .001) and height (mean ± SD, 26.0 ± 2.7 mm; p < .005). It also demonstrated a longer mean medial malleolus length (mean ± SD, 15.7 ± 2.4 mm; p < .005), a larger mean vertical neck angle (mean ± SD, 86.2 ± 5.4°; p < .050), and a greater mean tibial lateral surface angle (mean ± SD, 80.0 ± 4.5°; p < .001). And there was a greater mean frontal curvature depth (mean ± SD, 3.9 ± 0.6 mm; p < .005). Overall, this study found that patients with Hepple V osteochondral lesions of the talus had a larger vertical neck angle and tibial lateral surface angle, a longer talus radius and medial malleolus length, a higher talus height, and a deeper frontal curvature depth. STUDY DESIGNS: Retrospective Case-Control Study.
摘要：
本研究旨在确定距骨HeppleV型患者的踝关节骨骼结构特征。我们对110例HeppleV骨软骨病变患者和对照组的距骨结构进行了回顾性研究。射线照相测量包括以下内容：在冠状面上-距骨额叶曲率的深度，外侧和内侧踝的长度；在矢状平面中-距骨的半径和高度，胫骨外表面的角度，tibiotalar部门，和垂直颈部角度。距骨软骨损伤显示出明显较大的平均半径（平均值±SD，21.4±2.5mm；p<0.001）和身高（平均值±SD，26.0±2.7mm;p<0.005)。它还显示出更长的平均内踝长度(平均值±SD，15.7±2.4mm;p<0.005),较大的平均垂直颈部角度(平均值±SD，86.2±5.4°;p<0.050),和更大的平均胫骨外表面角(平均值±SD，80.0±4.5°；p<0.001）。并且平均额叶曲率深度更大(平均值±SD，3.9±0.6mm;p<0.005)。总的来说,这项研究发现，HeppleV骨软骨损伤患者的距骨有较大的垂直颈角和胫骨外表面角，较长的距骨半径和内踝长度，较高的距骨高度,和更深的正面曲率深度。
