解剖指引:彎曲異常

脊椎前凸脊柱後凸脊柱側凸

脊椎前凸
脊椎前凸(Lordosis)表示脊椎向後彎曲。正常的脊椎在頸部與下背(腰部)處向後彎。當這個彎度過於朝內時,稱為脊椎前凸或者背部過分下凹。

脊柱後凸
脊柱後凸(Kyphosis)字面上看來代表背部拱起,也就是脊椎往前彎曲的一種狀況。正常來說,中背段(胸椎)僅略為彎曲。脊柱後凸時,上背(胸椎)往前環繞。可能是先天的或者生產時的脊椎缺損所引起,或者是骨質疏鬆病患的壓迫性骨折所造成。

脊柱側凸
脊柱側凸(Scoliosis) 字面上看來代表彎曲,也就是脊椎彎向一側。有諸多原因,包括出生時的畸形、骨質疏鬆或者創傷造成的骨折、脊椎感染造成的傷害、神經或肌肉異常等。

骨質疏鬆症
骨質疏鬆症(Osteoporosis)是骨骼漸漸變得衰弱而容易受傷的一種現象。變弱的脊椎會因為體重塌陷或者因為一些小傷而骨折,甚至咳嗽也會產生影響。壓迫性骨折會導致身高減少,脊椎扭曲變形,有時候引起如老嫗般的駝背。
