Cervical degenerative disease is an aging phenomenon in humans. After 30 years of age, all people will gradually appear aging degeneration phenomenon, suffering from this disease, what examinations need to be done, let’s take a look at the following: cervical vertebral segment has obvious degeneration examination: In addition to the general symptoms of cervical spine injury, the main manifestation of the patient is the flexion of the neck forced position, head lifting difficulties, and in the posterior small joint with pressure pain. If the compression is severe, or the spinal canal is narrowed, or the cervical vertebral segments have obvious degeneration, there can be serious symptoms of spinal cord or spinal nerve root involvement, which should be carefully examined to determine the extent of the condition. 1, history of trauma: mainly due to flexion longitudinal violence; lateral wedge compression, mostly due to the cervical spine in a state of lateral bending. 2, clinical manifestations: as mentioned above, the lighter cases are dominated by cervical symptoms, while the heavier cases have a series of symptoms due to cervical vertebral segment instability. At this time, detailed examination should be required according to the neurological examination to confirm whether the symptoms are accompanied by spinal cord involvement. 3, imaging examination: according to the X-ray orthogonal and lateral films can mostly determine the diagnosis. In the conventional X-ray plain film can show a wedge-shaped widening of the spinous process gap, the vertebral body is also wedge-shaped, and there can be a triangular bone block in the subvertebral body. In severe wedge-shaped cases, there are spinal symptoms of varying degrees. MRI or CT should be used in such cases. Myelography can also be chosen for advanced cases (not suitable for early post-injury, but CTM examination can be performed as appropriate). 4.Test examination The test examination of cervical spondylosis, i.e. physical examination, includes: 1) Forward flexion and rotation test Make the patient flex his neck forward and ask him to rotate to the left and right. If there is pain in the cervical spine, it indicates degenerative changes in the small joints of the cervical spine. 2) intervertebral foramen squeeze test (pressure top test) make the patient’s head tilted to the affected side, the examiner’s left palm on the top of the patient’s head, the right hand clenched fist tapping the back of the left hand, then there is radiating pain or numbness in the limbs, indicating that the force downward transmission to the intervertebral foramen becomes smaller, there is radicular damage; for radicular pain is very strong, the examiner with both hands overlapping on the top of the head, intermittent pressure, can induce or aggravate the symptoms. A positive pressure test when the patient’s head is in a neutral or posterior extension position is called a positive Jackson head press test. 3) Brachial plexus pull test The patient lowers his head, the examiner holds the patient’s head and neck with one hand and the wrist of the affected limb with the other hand, pushing and pulling in opposite directions to see if the patient feels radiating pain or numbness, which is called the Eaten test. If pulling and then forcing the affected limb for internal rotation, it is called the Eaten strengthening test. 4) Upper limb posterior extension test The examiner places one hand on the shoulder of the healthy side to play a fixed role, and the other hand holds the patient’s wrist, and makes it gradually stretch backward and outward to increase the pulling on the cervical nerve root.
