Duchene - Erb's syndrome

Also known as outlined, neck nerve root syndrome; Upper brachial plexus palsy. Cause pathogenesis birth to the first arm traction brachial plexus palsy caused more persons. Adult caused by trauma, diseases such as cervical spine to the fifth and sixth cervical nerve root injury caused scapula and arm muscle weakness. Clinical manifestations forearm arm was extended from the ground, shoulder and upper arm muscle atrophy. Sensory dysfunction mainly distributed in the deltoid muscle, radial forearm and thumb of the lateral half. Differential diagnosis (1) neck injury (neck trauma) from the more top-down caused by external traction. If the carrying weights stretch injury. There neck and shoulder, scapula Department, chest and upper extremity pain, and the corresponding paralysis of the muscles and tendon reflexes weakened or disappeared, Neural owned distribution zone sensory dysfunction. (2) cervical disease (cervical spondylopathy) more common in adults after the age of 40 , the symptoms were gradually increased sexual initially tend to feel that the main obstacle to performance neck, shoulder and arm heavy flu, numbness and pain, with the gradually increasing the severity of the corresponding regional carotid denervation muscle paralysis, atrophy. Cervical disc disease with prominent Aristotle, Luschka joint hyperplasia, ossification of the posterior longitudinal ligament styles. (3) Multiple neck nerve root Yan (neck multiple rediculitis) disease often the precursor infection history, involving more nerve roots, not only for the performance of the upper brachial plexus syndrome, Brachial plexus may arise lower syndrome and brachial plexus Central syndrome, the performance of the hand and finger flexion, extension function obstacles, upper arm, forearm and hand the ulnar margin feeling barriers. TB usually involved bilateral cervical nerve root. (4) cervical lesions cervical syringomyelia, spinal cord tumors, such as the syndrome may arise, in addition to spinal cord still hemineglect syndrome. Sensory dysfunction was syringomyelia-Separation sensory dysfunction. (5) limitations cerebral cortex lesions may cause similar brachial plexus nerve root syndrome Duckene - Erb's - This sensory dysfunction found in head trauma and brain tumors.
