显微外科技术修复肌腱的实验研究——(二) 成人屈指肌腱血管密度研究

THE STUDY OF VASCULAR CONCENTRATION OF FLEXOR TENDO IN FINGER FROM HUMAN

用5只截肢的新鲜上肢标本,用体视学方法,研究了45条屈指肌腱的血管密度。结果为:成人屈指肌腱血管体积比为0.45％,单位体积的血管长度为1.9,不同屈指肌腱血管密度无显著差异,同一屈指肌腱在鞘管区段血管密度较掌、腕、前臂段为低,经统计学处理,有显著性差异。

Five fresh human forearms removed from cadavers were used to study the vascular concentration of the flexor digital tendons by stereology method. The results showed: (1) The Vv is 0.45%, and Lv is 1.9; (2) The vascular concentration of the flexor digital tendons of different fingers showed no significance statistically; (3) The vascular concentration of the tendons within the digital sheath was less than that outside the digital sheath (p<0.01); (4) The vascular concentration of the tendons were decreasing gradually from the thumb to litter finger.
