Naffziger's syndrome

Also known as outlined scalenus syndrome, Adson's syndrome, Coote's syndrome. Cause pathogenesis due to the former scalene muscle and, after the scalene muscle through the brachial plexus and the subclavian artery in the muscle between two compression caused. Take frequent cervical rib or malformation of the first rib, and other anatomical factors, as well as carrying heavy loads or use of muscle relaxants, such as ptosis Additional factors working together. Clinical features of the upper extremity from shoulder to the radiation of pain, paresthesia, muscle strength and reduce blood circulation to the upper extremity obstacles. Was particularly prevalent in the 20 - 30-year-old female, right see more. Symptoms generally occur gradually, the onset of pain are, to varying degrees, mainly for the performance from shoulder to the radiotherapy arm numbness and pain. to be strong at the hands of the ulnar margin, sometimes to radial expansion, scalenus first rib is attached to the Ministry of tenderness, arm extension and lateral rotation so that the pain got worse and try to jack up the elbow for passive upward shoulder pain relief, increased tired, rest at ease. Movement disorders arise later, the performance of muscle weakness and atrophy, in his own small hand muscles. Obstacles rare blood circulation, see the hand was Raynaud's phenomenon. Adosn test pilot shoulder-tight shoulder external rotation test positive. Seldinger do with subclavian arteriography and in light of the above can be clear compression test site. Differential diagnosis (1) amyotrophic lateral sclerosis (amyo trophic lateral scerosi s) is an adult sexual diseases. 30-year-old previously uncommon, usually in 40-50-year-old disease, the male preponderance. Clinical particularly implicit attack onset, slow increase of the upper and lower motor nerve paralysis, muscular atrophy and muscle fibrillation. Tendon hyperreflexia and pathological reflex, and have no sensory dysfunction, the most common symptom is the incidence of hand small muscle atrophy and weakness, gradually extended to the trunk and neck. EMG has diagnostic value. (2) syringomyelia (symptom) Refer Morvan's syndrome. (3) spinal cord tumors (spinal tumor) primary tumors were the most common in middle-aged and elderly metastatic tumors to the majority. Spinal cord tumors of nerve root compression caused the regional distribution of intermittent tingling or knife-like, electric shock-like pain, and the ants take, numbness paresthesia, and easy to confuse Naffziger's syndrome. But for spinal cord tumor development, part of the spinal cord compression, compression plane under the motor, feeling about the expansion muscle weakened or disappeared. Spinal film 50% see changes in bone and spinal angiography, CT, MRI useful for the diagnosis, especially in the largest value of MRI. (4) brachial plexus neuritis (brachial plexus neuritis) more common in adults. Often catch cold, influenza after acute or subacute onset of pain in the neck first roots and the upper clavicle, the rapid expansion of the posterior shoulder-length hair, A few days later that spread to the upper arm, forearm and hand, the beginning of intermittent pain was soon shall be sustained and extended to the entire upper extremity, Patients taking the arm elbow flexion posture. Weakened upper limb muscle strength, muscle atrophy and the skin barrier is not obvious. (5) cervical disease (cervical spondylosis) occurred in 40 ~ 60 years old, more men than women. Major performance for different levels of pain in the neck to the shoulder, arm, forearm and fingers radiation, associated with upper extremity sensory dysfunction and reduced tendon reflexes, and Hoffmann's levy, lower extremity increased muscle tone, hyperreflexia tendon pathology or any reflection. Should be combined with X-ray abnormalities comprehensive analysis. (6) cervical OPLL (ossification of the posterior long udinal ligment) demonstrated clinical cervical spondylotic myelopathy similar, previously believed cervical disease is a type, is defined as an independent disease. Pain in the cervical excessive activities there, the early symptoms of nerve root compression, fingers gradually to the neck, shoulder, Equality development arm, and then numbness, weakness, the limbs are not completely spastic paralysis, hyperreflexia with physiological and pathological reflex positive, Irregular sensory dysfunction and dispersion. X-ray films are characterized, lateral films can be seen in the cervical cord behind-ossifying shadow C2 range from under the extension, beyond 2-10 I vertebral range. (7) Other cervical disc and also, obliterans, Dupuy6tren's contracture. dermatomyositis, and other identification.
