I. How is cervical spine curvature retroflexion caused? Cervical curvature anteversion is mainly caused by long-term ambulatory work, head down, such as long-term like to play cell phones, play games, long-term paperwork will cause the original forward curvature of the cervical vertebrae gradually disappear, and then become cervical curvature straightening, and then further into the backward bending, called anteversion. Second, what is the effect of cervical curvature retroflexion? The force of the cervical spine is abnormally altered because of the change in the mechanics of the cervical spine caused by the retroflexion. Under such circumstances, the cervical intervertebral discs, including the hook vertebral joints, will easily degenerate, resulting in herniated cervical intervertebral discs and hyperplasia of the hook vertebral joints, further causing spinal stenosis of the cervical spine. Third, how to treat and prevent? When the cervical curvature is reversed, you should pay attention to your living habits, avoid long-term low-headed work, and do not play cell phones and computers for a long time with your head down. Strengthen the cervical spine resistance to forward bending and backward extension functional exercise, appropriate traction treatment. Local physiotherapy can relax muscle tension with hot compresses. In addition, you can do more aerobic exercise, such as swimming, playing badminton, running, etc. If the neck muscles are often fatigued and painful, you can wear an inflatable neck brace, which can provide moderate traction and muscle support protection for the cervical spine at home and easily allow the muscles to return to normal.
