Abstract

Background: This study aimed to compare various ankle alignment parameters in the hip-to-calcaneus (H-C) view and conventional whole-leg standing radiographs.

Methods: We retrospectively reviewed 61 patients with end-stage ankle arthritis (Takakura stage 3b/4) who underwent ankle arthrodesis. Preoperative H-C views and conventional radiographs were used to measure the hip-knee-ankle angle, weight-bearing line percentage, talar tilt, and medial distal tibial angle. The percentage of the H-C axis crossing the talus was also analyzed for asymmetry and correlated with the tibiocalcaneal angle, talar tilt, and hip-knee-ankle angle.

Results: Strong correlations were observed between the H-C view and conventional radiographs for the hip-knee-ankle angle (r = 0.88), weight-bearing line percentage (r = 0.90), and talar tilt (r = 0.87). The H-C axis asymmetry showed a strong correlation with tibiocalcaneal angle (r = -0.96).

Conclusions: The H-C view is a reliable tool for assessing hindfoot and lower limb alignment in end-stage ankle arthritis.

Level of evidence: III.

终末期踝关节关节炎患者髋关节-跟骨位踝关节对准的影像学评价。

背景：本研究旨在比较髋-跟骨（H-C）位和常规全腿站立x线片中各种踝关节对齐参数。方法：我们回顾性分析了61例接受踝关节融合术的终末期踝关节关节炎（Takakura 3b/4期）患者。术前使用H-C片和常规x线片测量髋关节-膝关节-踝关节角度、负重线百分比、距骨倾斜和胫骨内侧远端角度。还分析了H-C轴穿过距骨的百分比是否不对称，并与胫跟角、距骨倾斜和髋关节-膝关节-踝关节角相关。结果：髋-膝-踝关节角度（r = 0.88）、负重线百分比（r = 0.90）和距骨倾斜（r = 0.87）与常规x线片有很强的相关性。H-C轴不对称与胫跟角有很强的相关性（r = -0.96）。结论：H-C视图是评估终末期踝关节关节炎的后足和下肢对线的可靠工具。证据水平：III。

期刊介绍： Foot and Ankle Surgery is essential reading for everyone interested in the foot and ankle and its disorders. The approach is broad and includes all aspects of the subject from basic science to clinical management. Problems of both children and adults are included, as is trauma and chronic disease. Foot and Ankle Surgery is the official journal of European Foot and Ankle Society. The aims of this journal are to promote the art and science of ankle and foot surgery, to publish peer-reviewed research articles, to provide regular reviews by acknowledged experts on common problems, and to provide a forum for discussion with letters to the Editors. Reviews of books are also published. Papers are invited for possible publication in Foot and Ankle Surgery on the understanding that the material has not been published elsewhere or accepted for publication in another journal and does not infringe prior copyright.
