为了探讨排球运动对手部骨关节形态结构的影响,分析了青少年男排运动员腕骨CT图像的结构特点。选取省级青年队专业排球运动员9人（排球组）,非排球运动员11人（对照组）。用64排螺旋CT对手腕部进行扫描并三维重建,测量各腕骨体积及CT值（骨密度）。结果显示：与对照组各腕骨相比,排球组右手手舟骨和小多角骨,左手手舟骨、大多角骨和小多角骨体积均显著增加（P〈0.05）;排球组右手三角骨、豌豆骨、大多角骨、钩骨以及左手钩骨CT值明显小于对照组（P〈0.05）;排球组左手各腕骨体积及CT值与右手相比差异无显著性（P〉0.05）。结果说明：排球运动可使青少年男性运动员部分腕骨体积增大,骨密度降低;排球运动员非扣球手腕骨形态结构与扣球手发生相似的改变。

In order to probe into the effects of volleyball on the morphological structures of carpal bones of volleyball players,the authors analyzed the structural characteristics of CT images of carpal bones of mage teenage volleyball players.The authors selected 9 professional volleyball players（the volleyball group） and 11 non volleyball players（the control group） from provincial teenage teams,and used a 64-row spiral CT scanner to scan the wrists of the players and reconstruct a 3D image of their wrists,measured the volumes and CT values（bone densities） of carpal bones,and revealed the following findings： as compared with carpal bones of the players in the control group,the volumes of the scaphoideums and trapezoideums of the right hands and the scaphoideums,trapeziums and trapezoideums of the left hands of the players in the volleyball group were significantly higher（P0.05）;the CT values of the triquetrums,pisiforms,trapeziums and hamatums of the right hands and the hamatums of the left hands of the players in the volleyball group were significantly smaller than those of the players in the control group（P0.05）;there was no significant difference in carpal bones and CT values between the right hands and left hands of the players in the volleyball group（P0.05）.The said findings indicate the followings： volleyball can increase the volumes and lower the densities of some carpal bones of male teenage players;the morphological structures of carpal bones of the hands of non spiker volleyball players have changes similar to those occurring to spikers.
