解剖指引:弯曲异常

脊椎前凸脊柱后凸脊柱侧凸

脊椎前凸
脊椎前凸(Lordosis)表示脊椎向后弯曲。正常的脊椎在颈部与下背(腰部)处向后弯。当这个弯度过于朝内时,称为脊椎前凸或者背部过分下凹。

脊柱后凸
脊柱后凸(Kyphosis)字面上看来代表背部拱起,也就是脊椎往前弯曲的一种状况。正常来说,中背段(胸椎)仅略为弯曲。脊柱后凸时,上背(胸椎)往前环绕。可能是先天的或者生产时的脊椎缺损所引起,或者是骨质疏松病患的压迫性骨折所造成。

脊柱侧凸
脊柱侧凸(Scoliosis) 字面上看来代表弯曲,也就是脊椎弯向一侧。有诸多原因,包括出生时的畸形、骨质疏松或者创伤造成的骨折、脊椎感染造成的伤害、神经或肌肉异常等。

骨质疏松症
骨质疏松症(Osteoporosis)是骨骼渐渐变得衰弱而容易受伤的一种现象。变弱的脊椎会因为体重塌陷或者因为一些小伤而骨折,甚至咳嗽也会产生影响。压迫性骨折会导致身高减少,脊椎扭曲变形,有时候引起如老妪般的驼背。
