椎间盘是相邻两个椎体间的一个弹性结构,由外层坚韧无弹性的纤维环以及其内部胶冻状的髓核组成,具有承载压力和缓冲冲击震动的重要功能。当椎间盘承受过度压力和扭转力时,椎间盘就会退变、突出。实际上人体腰椎的退变从20岁就开始了,因此,发生腰椎间盘突出是人体衰老的自然生理过程。从侧面看,人体的脊柱有4个生理弯曲,特别是腰椎凸向前方的生理弯曲对维持身体直立特别重要。腰椎负担上半身重量,活动度很大。因此,腰椎间盘最容易受到伤害。如果长时间的歪斜坐姿、弯腰弓
The intervertebral disc is an elastic structure between two adjacent vertebral bodies. It consists of a tough, inelastic fibrous ring outer layer and its internal jelly-like nucleus, which has the important function of bearing pressure and shock-absorbing shock. When the disc to withstand excessive pressure and torque, the disc will degenerate, highlight. In fact, the degeneration of the lumbar spine began from the age of 20, so the occurrence of lumbar disc herniation is a natural physiological process of aging. From the side view, the body’s spine has four physiological bending, in particular, lumbar convex to the front of the physiological curvature of the body to maintain erection is particularly important. Lumbar burden upper body weight, great activity. Therefore, the lumbar disc is the most vulnerable. If you sit for a long time, bend your bow
