背景:骨结构已被证明是慢性踝关节不稳(CAI)的危险因素。以前,研究人员只关注脚踝的骨结构,但忽略了距下关节(STJ)的骨结构。因此,我们的研究目的是研究CAI中STJ骨结构的形态特征。
方法:选取西南医科大学附属中医医院52例CAI患者和52例性别、年龄相匹配的对照组。采用负重踝关节侧位片比较两组的差异。具体来说,跟骨的长度,跟骨小平面高度和脚的绝对高度,Böhler的角度,Gissane\的角度,跟骨倾角,Talocalcanalangle,胫骨角,胫骨角,Talar-水平角,距骨偏角,测量两组的面倾角。
结果:伯勒的角度,跟骨倾斜,Talocalcanalangle,胫骨角,Talar-水平角,距骨偏角,CAI组切面倾角和足部绝对高度均显著高于正常对照组(P<0.05)。Gissane的角度没有显著差异,胫骨角,CAI患者跟骨长度和跟骨小关节高度与正常对照组比较(P>0.05)。
结论:CAI患者的STJ骨结构在形态上与正常人不同。因此,在CAI的诊断和预防中,应重视STJ解剖参数的变化。

BACKGROUND: Osseous structures have been demonstrated as risk factors for chronic ankle instability (CAI). Previously, the researchers only focused on the osseous structures of ankle, but ignored the osseous structures of subtalar joint(STJ). Accordingly, the aim of our study was to investigate the morphological characteristics of STJ osseous structures in CAI.
METHODS: 52 patients with CAI and 52 sex- and age- matched control subjects were enrolled from The Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University. The lateral radiographs of ankle in weight-bearing were used to compare the diversity of the two groups. Specifically, The Length of calcaneus, Calcaneal facet height and Absolute foot height, Böhler\'s angle, Gissane\'s angle, Calcaneal inclination angle, Talocalcaneal angle, Tibiotalar angle, Tibiocalcaneal angle, Talar-horizontal angle, talar declination angle, facet inclination angle were gauged in the two groups.
RESULTS: The Böhler\'s angle, Calcaneal inclination, Talocalcaneal angle, Tibiotalar angle, Talar-horizontal angle, Talar declination angle, Facet inclination angle and Absolute foot height of CAI group were significantly higher than normal control group (P < 0.05). There were no significant differences in Gissane\'s angle, Tibiocalcaneal angle, Length of calcaneus and Calcaneal facet height between patients with CAI and normal controls (P > 0.05).
CONCLUSIONS: The osseous structures of STJ in CAI patients are different from normal people in morphology. Therefore, we should pay more attention to the changes of STJ anatomical parameters in the diagnosis and prevention of CAI.
