背景：慢性踝关节不稳定（CAI）是运动中常见的骨科疾病。尽管其他危险因素已被广泛研究，但对骨性关节结构对其的影响知之甚少。目的：探讨骨性踝关节形态对CAI的影响。设计：病例对照研究，III级。设置：由独立放射科医生使用数字DICOM/PACS系统进行侧位x线测量的放射检查。患者：52名至少有过三次复发性扭伤的患者与52名年龄和性别匹配的健康对照组进行了比较。主要观察指标：测量距骨面半径、距骨胫骨覆盖范围（胫距段）和距体高度。结果：CAI患者距骨半径（21.2 (2.4)mm）大于对照组（17.7 (1.9)mm）；P < 0.001，功率bb0 95%)。CAI患者的胫距区（80度（5.1度））小于对照组（88.4度（7.2度））；P < 0.001，功率bb0 95%)。CAI患者距体高度（28.8 (2.6)mm）与对照组（27.5 (4.0)mm）无显著差异；P = 0.055)。结论：CAI与不稳定的骨性关节结构有关，其特征是距骨半径较大，胫距区较小。有证据表明，较高的距骨也可能起到一定作用，尤其是对女性而言。
Background: Chronic ankle instability (CAI) is a common orthopaedic entity in sport. Although other risk factors have been studied extensively, little is known about how it is influenced by the osseous joint configuration.Aim: To study the effect of osseous ankle configuration on CAI.Design: Case-control study, level III.Setting: Radiological examination with measurement of lateral x rays by an independent radiologist using a digital DICOM/PACS system.Patients: A group of 52 patients who had had at least three recurrent sprains was compared with an age-matched and sex-matched control group of 52 healthy subjects.Main outcome measures: The radius of the talar surface, the tibial coverage of the talus (tibiotalar sector) and the height of the talar body were measured.Results: The talar radius was found to be larger in patients with CAI (21.2 (2.4) mm) than in controls (17.7 (1.9) mm; p < 0.001, power >95%). The tibiotalar sector, representing the tibial coverage of the talus, was smaller in patients with CAI (80 degrees (5.1 degrees)) than in controls (88.4 degrees (7.2 degrees); p < 0.001, power >95%). No significant difference was observed in the height of the talar body between patients with CAI (28.8 (2.6) mm) and controls (27.5 (4.0) mm; p = 0.055).Conclusion: CAI is associated with an unstable osseous joint configuration characterised by a larger radius of the talus and a smaller tibiotalar sector. There is evidence that a higher talus might also play some part, particularly in women.
