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 all 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)° (P < 0.05). The length, width and height of Chinese calcaneus were significantly lower than those of westerners (P < 0.05). The Bohler’s angle and Gissane’s angle in Chinese adults showed no statistical significance compared with the westerners (P > 0.05). Experimental findings indicate that, the length, width and height of Chinese calcaneus in female were lower than that in male, but 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.
