Cervical spinal stenosis cervical defense sign: Such patients often keep their necks in a natural supination and extension position (functional position), which allows forward flexion and fears supination and extension. Under normal conditions, the internal diameter of the cervical spinal canal (anterior and posterior sagittal diameters and left and right transverse diameters) is of a certain size to accommodate the spinal cord nerves and other tissues in the spinal canal. However, if the internal diameter is less than normal, especially if the absolute sagittal diameter is less than 12 mm, it constitutes a relative stenosis of the spinal canal, and less than 10 mm is an absolute stenosis, which can lead to a series of symptoms. The treatment of this disease is still based on non-surgical treatment, but the sagittal diameter of the spinal canal should be expanded surgically if the treatment is ineffective for a long time. The general dietary principles for patients with forward flexion of the neck and fear of supination and extension are: a reasonable diet, a reasonable diet, and no single partial diet. 2, the neck can be forward flexion, fear of supination patients are generally divided into two categories of food: one is the main food, mainly to provide calories, such as rice, noodles, belong to this type of food; another food, can regulate physiological functions, known as side dishes, such as beans, fruits and vegetables. The nutrition contained in the main food is different, coarse and fine to eat at the same time, not a single partial food. Coarse and fine, dry and sparse, main and secondary with a comprehensive nutrition can meet the needs of the body, to promote the recovery of patients and maintain the needs of the normal body. 3, the neck can be forward flexion, fear of supination and extension patients need to eat symptomatically: because cervical spondylosis is caused by vertebral hyperplasia, bone degeneration and osteoporosis, so cervical spondylosis patients should be rich in calcium, protein, vitamin B, vitamin C and vitamin E diet. Calcium is the main component of bone, with milk, fish, pig tail bones, soybeans, black beans and other content as much. Protein is also an indispensable nutrient for the formation of ligaments, bones and muscles. Vitamins B and E, on the other hand, can relieve pain. Relieve fatigue. Experts remind you that if cervical spondylosis is a damp-heat blocking meridians, you should eat more fruits and vegetables such as kudzu, bitter melon, loofah, etc. that clear heat and unblock the muscles; if it is a cold-damp blocking meridians, you should eat more food such as dog meat, mutton, etc. that warm the meridians and disperse cold; if it is a blood deficiency and qi stagnation, you should eat more food such as rooster, carp and black beans. In short, the right food, can be conducive to the recovery of the neck can be forward flexion, fear of supination and extension patients.
