【摘要】 <正> 足弓具有缓冲行走时产生的振动,保护足底血管和神经免于受压的作用。若维持足弓组织过度劳损、先天性软组织发育不良或骨折损伤,均可导致足弓变形塌陷,形成扁平足关于足弓的记载已有很多,在教科书上也有较详细的记述(H.Gray,G.J.Romanes)。足弓的 X 线测量,L.R.Sonte记载得很详细。国内,卢小娥、李景学、张芳等也作过报导。但对足弓各角度的测量及其在负重后的变化方面,报导不多。尤其中国人足弓的标准,尚需作大量的调查测量工作,以确定正常数值。为此目的,我们对101青年的202只足进行了足弓的 X 线照片测量,报导如下:更多还原

【Abstract】 We measured 202 foot arches of normal youths by roentgenogram,including 102 males and 100 females. a.The average angle of the male’s medial longitudinal arch is 121.07 + 0.57° and that of the female’s is 122.58 + 0.53°.But when loaded,the male’s medial longitudinal angle increases by 4.73° and the female’s increases by 6.04°.The average height of the male’s longitudinal arch is 39.48±0.35mm while that of the female’s is 35.64±0.32mm.when loaded,the height of male’s medial longitudinal arch decreases by 3.24mm and that of the female’s decreases by 3.74mm. b.Anterior angle.The male’s anterior angle is 19.77+ 0.30° on an average. When loaded,the angle is 17.59+0.29°.The female’s anterior angle is 18.81±0.32°.When loaded,the angle is 15 c.Lateral longitudinal arch angle.The male’s lateral longitudinal arch angle is 143.22±0.63° and female’s is 146.14+0.63° on an average.The angle increases when loaded.The average height of male’s lateral longitudinal arch is 20.17+ 0.29mm.That of female’s is 17.50+0.30mm. d.Posterior angle.The male’s posterior angle is 22.07+0.41° and female’s is 20.58+0.39° on an average.There is no significant difference between the leftside and right side in the items mentioned above,but a significant difference does exist between sexes. e.Calcaneo-astrgalar angle(Boehler):The mean angle of the male’s and female’s is 39.08±0.60° and 38.41±0.66° respectively.There is no significant difference between sides as well更多还原
