What are the examination methods of cervical spondylosis?

X-ray examination X-ray examination should be a routine examination for the diagnosis of cervical spondylosis. X-ray includes positive position, lateral position and double oblique position. According to the need, you can take over-stretched and over-stretched lateral films. 2. Tomography Tomography can avoid overlapping on plain films and can be used to observe earlier and smaller lesions that are difficult to display on general X-rays. 3. myelography myelography can know the location, degree and scope of spinal cord compression, and can exclude new organisms and congenital malformations in the spinal canal. However, spinal puncture and contrast agent itself will cause a series of problems and various reactions, so it is necessary to be cautious when applying this examination. 4. Vertebral angiography The diagnosis of cervical spondylosis of vertebral artery type is mainly based on clinical examination. Vertebral arteriography is generally only used for preoperative diagnosis and location. 5. EMG examination EMG examination is to observe the electrical activity of muscles at rest and actively contract and stimulate peripheral nerves. Measuring the conduction velocity of peripheral nerve is helpful for the diagnosis of neuromuscular diseases and peripheral nerve injury. Judging the degree of injury is helpful to distinguish the diseases of superior neurons or inferior neurons. 6.CT scanning CT scanning can accurately understand the size and shape of spinal canal, the size and position of osteophyte, the ossification of posterior longitudinal ligament and ligamentum flavum, its position and scope, and understand the shape of spinal cord in spinal canal and its relationship with surrounding diseases. Therefore, CT scan can be used as an important basis for preoperative diagnosis and choice of surgical methods. Although CT scanning has many advantages, small lesions between two sections are easy to be missed, so the judgment should be closely combined with clinical and other examinations. 6. Magnetic resonance imaging (MRI) can obtain the three-dimensional structure of cervical spine, and can observe the structural changes in cervical spinal canal from sagittal plane, transverse plane and coronal plane. The sagittal diameter of the spinal canal, osteophyte at the edge of the vertebral body, nucleus pulposus protrusion and new organisms in the spinal canal, especially the spinal cord itself, can be easily detected. In addition, arachnoid adhesion and its degree can also be directly judged.
