What diseases are cervical spondylosis easily confused with? A. Neurogenic cervical spondylosis needs to be differentiated from the following diseases 1. cervical rib and anterior oblique muscle syndrome: the patient is young and mainly shows symptoms of compression of the lower brachial plexus, such as medial numbness of the upper limb, atrophy of the interosseous and interosseous muscles. The Adson test (head turned to the affected side, deep inspiration followed by temporary breath-holding, weakening or disappearance of radial artery pulsation) is positive. Cervical radiographs can confirm cervical ribs. 2. Extramedullary subdural tumors in the spinal canal, neurofibromas in and around the intervertebral foramen, and tumors near the pulmonary apex (Pancoast tumor) can cause upper extremity pain. Cervical spine radiographs may reveal signs of occupying lesions in the spinal canal and enlarged intervertebral foramina without cervical degenerative changes, CT or MRI may directly show tumor images, and patients with Pancoast tlamor are also accompanied by Horner’s syndrome. 3.Neuralgic muscular atrophy: It often involves C5 distribution area, causing severe pain, shoulder muscle weakness and atrophy. However, the sensory impairment is mild, and the symptoms can often be relieved more quickly, and usually do not involve the neck. 4.Angina pectoris: The pain can radiate to the upper limbs and shoulders and neck, but it is mostly episodic and can be relieved by oral nitroglycerin tablets, etc. The patient has a history of coronary heart disease, and it is generally not difficult to differentiate. 5.Tendon sleeve syndrome: The main manifestation is shoulder abduction weakness and pain after abduction more than 30. There is local pressure pain in the tendon, which is different from nerve root pain. 6.Rheumatic polymyalgia: similar to brachial plexus neuralgia, but not accompanied by movement disorders. Spinal cord cervical spondylosis should be differentiated from the following diseases 1. amyotrophic lateral sclerosis: spastic quadriplegia is the main cause, without sensory disorders, and often invades the medulla oblongata and presents symptoms of the lower group of cranial nerves. 2.Multiple sclerosis: symptoms of brain and spinal cord often appear at the same time, and bladder dysfunction mostly occurs before limb movement disorders. 3.Intravertebral tumor: It can occur at any age, and the symptoms develop quickly. Various imaging tests can help to identify them. 4, spinal cord cavity: mainly manifested as sensory disorders, motor disorders appear later. MRI can clearly show the thickening of the central canal of the spinal cord. Vertebral artery type cervical spondylosis is relatively rare and needs to be differentiated from other causes of inadequate blood supply to the vertebral basilar artery, such as atherosclerosis and developmental abnormalities of the vertebral artery. Vertebral arteriogram is the most reliable method of differentiation.
