摘　　要：背景:跟骨为不规则骨,具有复杂的三维立体结构,过往多基于X射线平片进行测量研究,利用螺旋CT三维成像技术进行跟骨相关解剖测量具有明显的技术优势与良好的应用前景,但目前报道较少。目的:利用螺旋CT三维重建测量国人跟骨的解剖数据并探讨其临床意义。方法:收集100例成人正常跟骨CT扫描数据,男50例,女50例,将其重建后进一步测量跟骨长、宽、高及Bohler’s角及Gissane’s角,将测量数据与西方人数据进行对比。结果与结论:中国男性组跟骨长、宽及高分别为(74.60±5.06),(29.71±2.93),(45.23±4.46)mm;女性组为(71.48±5.36),(26.65±3.01),(42.23±4.49)mm,男性组显著大于女性组(P<0.05)。男性组Gissane’s角度为(123.3±8.5)°,女性组为(122.7±8.9)°,差异无显著性意义(P>0.05)。男性组Bohler’s角为(35.98±4.34)°,女性组为(38.31±4.43)°,男性组显著小于女性组(P<0.05)。国人跟骨全长、宽度及高度显著小于西方人数据(P<0.05)。中国成人Bohler’s角及Gissane’s角测量数据与西方人比较差异无显著性意义(P>0.05)。提示中国女性成人跟骨长、宽、高较男性小,跟骨Bohler’s角明显大于男性,不同性别间Gissane’s角无明显差异。与西方人相关数据比较,中国成人的跟骨长、宽、高明显偏小,跟骨Bohler’s角及Gissane’s角则无明显差异。BACKGROUND：Calcaneus is a kind of irregular bone, with complicated three-dimensional structure. Calcaneus is often measured with X-ray plain film, while spiral CT three-dimensional imaging is a potent technology for anatomic measurement and has good application prospect. However, little is known about it. OBJECTIVE：To measure calcaneal anatomic data in Chinese peoples with spiral CT three-dimensional reconstruction and to explore its clinical significance. METHODS：Calcaneal spiral CT three-dimensional reconstruction in 100 Chinese adults （including 50 males and 50 females） were performed. The length, width, height of calcaneus, and Bohler’s and Gissane’s angles were measured after reconstruction, and compared with the data of westerners. RESULTS AND CONCLUSION：The mean length, width and height of the Chinese calcaneus were respectively （74.60±5.06） mm, （29.71±2.93） mm and （45.23±4.46） mm in male group, and （71.48±5.36） mm, （26.65±3.01） mm and （42.23±4.49） mm in female group. There were no significant differences between male group and female group in al the above parameters （P〉0.05）. There was no significant difference in the Gissane’s angle between the two groups （123.3±8.5° versus 122.7±8.9°;P〉0.05）. The Bohler’s angle in male group （35.98±4.34）° was significantly lower than that in female group （38.81±4.43）° （P0.05）. Experimental findings indicate that, the length, width and height of Chinese calcaneus in female were lower than that in male, but＆nbsp;Bohler’s angle is significantly higher than that in male, there was no significant difference in Gissane’s angle between males and females. Compared with the data of westerners, the length, width and height of Chinese adult calcaneus are significantly decreased, and no difference is found in Bohler’s angle and Gissane’s angle.
