cervical dorsal branch entrapment
Introduction
Introduction to cervical nerveback compression syndrome The various extraspinal nociceptive stimuli that cause neck and shoulder pain are mainly transmitted to the central branch of the posterior branch of the spinal nerve (back branch). Therefore, in recent years, the main afferent nerve (neck nerve branch) of neck and shoulder pain caused by extraspinal causes The morphology has been studied a lot, and it is suggested that the compression of the cervical nerve dorsal branch is an important cause of head and neck pain and pain in the shoulder and upper limb. The joint joint of the medial branch of the dorsal branch of the cervical nerve is considered to cause the neck and shoulder. The main source of pain. For patients with head, neck and shoulder pain without obvious neurological signs, the possibility of cervical nerve back pain should be considered. basic knowledge The proportion of illness: 0.005% Susceptible people: no special people Mode of infection: non-infectious complication:
Cause
Causes of cervical nerve back compression
(1) Causes of the disease
The facet joints that are supported by the medial branch of the dorsal nerve of the cervical nerve are considered to be the most common cause of neck and shoulder pain.
(two) pathogenesis
The cause of extraspinal nerve is through the peripheral nerve afferent center, which is mainly caused by the posterior branch of the cervical nerve. Therefore, the main afferent nerve, which is the main afferent nerve of neck and shoulder pain caused by extra-spinal tuberculosis, is the position of the cervical nerve dorsal branch in neck and shoulder pain. A large number of studies have been done by anatomical and clinical scholars at home and abroad. It is currently believed that the cervical nerve dorsal branch and the joint and joint disease that it dictates are important sources of neck and shoulder pain.
Prevention
Cervical nerve dorsal artery compression prevention
Early detection and early diagnosis are the key to the prevention and treatment of this disease.
Complication
Cervical nerve dorsal compression complications Complication
No special complications, ear, lower occipital, neck pain, may be associated with shoulder, shoulder and chest wall pain.
Symptom
Cervical nerve dorsal artery compression symptoms common symptoms involved pain
1. History and symptoms
Most of them have a history of trauma. There is no significant difference between men and women. The main symptoms are pain and discomfort in the ear, lower occipital, and neck. It can be accompanied by shoulders, shoulder blades, pain in the front chest wall, rotation of the head, and increased pain during overextension. There are no other neurological symptoms, no symptoms of nerve root injury, and the range of pain caused by Sei Fukui et al.
(1) Neck 1, 2: the posterolateral part of the neck.
(2) Neck 3: The upper part of the occiput and the back of the neck.
(3) Neck 4: the middle and lower part of the back of the neck, the upper part of the shoulder.
(4) Neck 5: The lower part behind the neck.
(5) Neck 6: The upper corner of the shoulder blade.
(6) Neck 7: middle of the shoulder and lower scapula.
2. Signs
(1) The head rotates and the pain is exacerbated when it is overextended.
(2) There is obvious tenderness at the joints of the paraspinal joints.
(3) The ear circumference, the lower occipital part, and the neck part may have a feeling change.
(4) No signs of nerve root damage.
Examine
Examination of cervical nerveback compression syndrome
Cervical vertebrae, lateral X-ray film: visible cervical degenerative changes.
Diagnosis
Diagnosis and differentiation of cervical nerve dorsal stenosis
Diagnostic criteria
1. Ear circumference, lower occipital part, neck pain, may be accompanied by shoulders, scapula, and the front chest wall is involved in pain.
2. No nerve root damage performance.
3. Local closure of the cervical nerve dorsal or facet joints can alleviate or eliminate symptoms.
Differential diagnosis
1. The fifth cervical nerve posterior branch compression
The nature of pain is similar to that of the posterior branch of the cervical nerve, but often the phrenic nerve is involved at the same time. The deltoid muscle is atrophy and the lateral lateral sensation is reduced. The tender point is mainly at the midpoint of the posterior margin of the sternocleidomastoid muscle.
Cervical spondylosis
Peripheral nerve injury manifested as brachial numbness and weakness, neck activity was associated with upper arm pain, dome test and neck and shoulder pull test were positive, and neck X-ray and MRI examination were helpful for differential diagnosis.
3. Shoulder inflammation
More common in middle-aged people around the age of 50, mainly characterized by shoulder pain and limited mobility, passive activities are also limited, the front of the shoulder is the biceps femoris tendon sheath tenderness is obvious.
4. Shoulder joint impact
Shoulder joint pain has a pain arc of 80 ° ~ 120 °, tenderness mainly under the shoulder.
