Symptoms + physical signs + imaging are required to confirm a diagnosis of cervical spondylosis. Diagnosis of cervical spondylosis requires clinical symptoms, physical examination and imaging of the patient. Although there are many auxiliary examinations available, a detailed in-person consultation and careful physical examination by a physician are still indispensable. Commonly used ancillary examinations include cervical spine x-ray, CT and MRI. Cervical spine X-ray includes orthogonal and lateral films of the cervical spine, mainly to see whether the overall physiological curvature of the cervical spine is abnormal, whether there is osteophytes and ligament calcification in the front and back, and whether the nerve root foramen is narrowed in special positions such as double oblique X-ray. Usually, X-rays are used for preliminary screening. Cervical spine frontal and lateral X-ray cervical spine double oblique X-ray MRI is also a common means of examining the cervical spine. Nowadays, MRI films are becoming clearer and can provide doctors with a lot of accurate information. The MRI can see if the patient has bone growth and compression, and if there is compression, whether the compression is on the nerves or the spinal cord. If a patient is unable to have an MRI because of a contraceptive ring, pacemaker, or claustrophobia, the next best thing is to have a CT of the cervical spine. CT is particularly advantageous in determining whether there is ossification of the cervical spine (ossification means that what should be soft tissue becomes bony, such as ossification of the posterior longitudinal ligament). Sometimes both MRI and CT may be required to develop a surgical plan. CT of the cervical spine In order to diagnose cervical spondylosis, sometimes patients need to have some electromyography and evoked potentials. This is a localization test that can determine which nerve root is being compressed and is often relied upon for the diagnosis of orthopedic conditions.
