目的研究足印角及C-S指数与扁平足内侧纵弓的相关性,探讨应用足印角及C-S指数诊断扁平足的可行性。方法选取162例受试者(308足)的双足负重正侧位X线片和Harris Mat足印图。负重侧位X线图像上测量距骨第1跖骨角,跟骨倾斜角,距骨倾斜角和距骨跟骨角。Harris Mat足印图测量足印角及C-S指数。根据距骨第1跖骨角将研究对象分为:正常足弓组,轻度扁平足组,中度扁平足组和重度扁平足组,将内侧纵弓各测量结果与其对应的足印角和C-S指数进行差异性及相关性分析。结果足印角:正常足为(42.79±6.93)°,轻度扁平足为(31.73±8.44)°,中度扁平足为(21.07±12.6)°,重度扁平足为(5.50±1.19)°,差异有统计学意义(F=63.90,P=0.000);C-S指数:正常足为0.37±0.05,轻度扁平足为0.41±0.05,中度扁平足为0.46±0.11,重度扁平足为0.69±0.20,差异有统计学意义(F=39.70,P=0.000);距骨第1跖骨角与足印角呈负相关关系,左足的相关系数为-0.646,右足的相关系数为-0.752;距骨第1跖骨角与C-S指数呈正相关关系,左足的相关系数为0.514,右足的相关系数为0.575;内侧纵弓与足印角及C-S指数呈显著性相关关系。结论足印角和C-S指数是测量和评价扁平足内侧纵弓的可靠指标;足印图测量结果有助于扁平足的早期诊断和分级,并指导扁平足的二级预防。
Objective To investigate the relationship of Clarke angle and Chippaux-Smirak （ C-S ） index with the medial longitudinal arch and to explore the feasibility in the diagnose of flatfoot deformity by using the Clarke angle and C-S index. Methods A total of 162 subjects （ 308 feet ） were enrolled, whose weight-bearing anteroposterior and lateral X-ray films and Harris mat footprints of both feet were collected. On the weight-bearing lateral X-ray films, the talo-first metatarsal angle, calcaneal pitch angle, talus tilt angle and talocalcaneal angle were measured. On the Harris mat footprints, the Clarke angle and C-S index were measured. According to the talo-first metatarsal angle, the subjects were divided into 4 groups： normal arch group, mild fatfoot group, moderate flatfoot group and severe flatfoot group. The difference and correlation analyses were conducted between the medial longitudinal arch measurement results and the corresponding Clarke angle and C-S index. Results The Clarke angles were （ 42.79 ~ 6.93 ） o, （ 31.73 ~ 8.44 ） o, （ 21.07 ＋ 12.6 ） ~ and （ 5.50 ＋ 1.19 ） o in normal arch group, mild flatfoot group, moderate flatfoot group and severe flatfoot group respectively, and the differences among them were statistically significant （ F= 63.90, P = 0.000 ）. The C-S indexes were 0.37 ± 0.05, 0.41±0.05, 0.46 ±0.11 and 0.69 ± 0.20 in normal arch group, mild flatfoot group, moderate flatfoot group and severe flatfoot group respectively, and the differences among them were statistically significant （ F = 39.70, P = 0.000 ）. There was a negative correlation between the talo-first metatarsal angle and the Clarke angle, and the correlation coefficients were -0.646 for the left foot and -0.752 for the right foot. The talo-first metatarsal angle and the C-S index were positively correlated, and the correlation coefficients were 0.514 for the left foot and 0.575 for the right foot. There was a significant correlation between the medial longitudinal arch and the Clarke angl
