Calcification of ligaments in cervical spondylosis, the causes of calcification of ligaments in cervical spondylosis are as follows: First, because of long-term poor posture, such as working with the head down, playing with cell phones for a long time, or because of exertion and cold, but also because of injuries or fractures caused by ligamentous calcification; Second, ligamentous calcification of the site, the anterior longitudinal ligament is easy to cause after calcification of the esophagus compression, this is relatively rare, the most common is the proliferation and calcification of posterior longitudinal and ligamentum flavum. The most common cases are proliferation and calcification of the posterior longitudinal ligament and ligamentum flavum, because cervical spondylosis itself has herniated discs, which compresses the nucleus pulposus, nerve roots and spinal cord, and if the ligamentum flavum is added to the discs, it will result in spinal stenosis, which will lead to weakness of the lower limbs and instability in the body, and if the condition is serious, surgery is needed, but if it is relatively mild, it can be treated conservatively, and the medicines for activating blood circulation and removing blood stasis or the medicines for nutritive nerves can be used. Too much activity, calcification need to pay attention to avoid bad posture, at the same time can carry out appropriate exercise of the cervical spine.
