1.What are the clinical manifestations of cervical cervical spondylosis? Neck pain and straightness, pain in the whole spine, stiffness, limited head flexion and rotation in a sloping neck position. The neck and trunk must rotate together when turning back. A few patients may have reflex shoulder, arm and hand pain, as well as swelling and numbness, but there is no radiological increase in the upper limbs when coughing or sneezing. The patient has head, neck, shoulder, and arm pain with corresponding pressure points at the lesion, but there are no degenerative changes such as spinal space narrowing on the X-ray. This type of cervical spondylosis is an early lesion. It is caused by strain on the neck muscles and ligament joints due to long-term single posture of the head and neck. Patients often have easy fatigue in the neck, cannot read and write for a long time, often feel stiffness in the neck in the morning, inflexible activities, and a sense of ringing when moving. 2.What are the clinical manifestations of neurogenic cervical spondylosis? In the early stage, the symptoms are not typical, and the function of the neck activity is basically normal, but with the aggravation of osteophytes, the patient has pain and numbness in the neck, shoulder, arm and hand, but the numbness mostly appears in the fingers and forearm, and can be radiated upward to the occiput. The symptoms can be triggered or aggravated by a change in neck position, especially when the neck is suddenly rotated backwards. Some patients have muscle atrophy in the forearm and hand, sensory impairment and muscle weakness. The cervical foraminal compression test and brachial plexus nerve pull test are positive, and the affected spinal process is positive for pressure pain. Cervical 5-6 was the best site of hyperplasia. When the hyperplasia stimulated the nerve root of cervical 6, pain and numbness along the neck and shoulder to the lateral side of the upper arm and the radial side of the forearm and wrist, and radiated to the thumb and index finger, and when the hyperplasia stimulated its nerve root, numbness and pain symptoms along the above route to the index and middle fingers, reduced biceps muscle strength, abnormal tendon reflexes, and pressure pain in the supra-scapular angle. X-ray examination of oblique film shows that the spur of the hook vertebral joint protrudes into the intervertebral foramen, and the intervertebral foramen becomes smaller or irregular.
